When I made my first large field collection, in North Sulawesi (still
analysing data...) I killed many fishes.
I grew so disgusted by killing those wonderful creatures (even if I tried
to do it in the fastest and putatively less painful way, by cold), that I
decided not to sacrifice them anymore, but to take fin-clips for the DNA.
I collected about one-third of the whole collection in this way.
To be honest, I had some problems in subsequent developments of the
study, since I didn't have so many morphological specimens to compare
some genetic variants, nonetheless, I found another way.
I tried another analytical technique: I used an emulsion of clove oil and
ethanol to anesthetize them. I made several trials with concentrations
and timings, and I found a good protocol to assure that they could be
examined in a convenient time, wait for them to completely recover, and
release them the next day.
I can say that with the exception of the body colouration, which is
sometime altered during anesthesia (but that can be documented in a few
freshly killed specimens or in live ones), all other types of external
measures and counts can be made on anesthetized specimens, which can
completely recover also after 1/2 hr of anesthesia.
Basic measurements as length and weight can also be made on live and not
anesthetized specimens, straightening them in a transparent polyethylene
bag for a few moments.
In some of my subsequent field studies (e.g. Polgar and Crosa 2009), I
used to make a small reference collection of all the studied species (to
be deposited in museums) and then ID species in the field. I can say that
if you get sufficiently acquainted with the studied species, it is
definitely possible to visually ID them in the field (see also Takita et
al. 1999), at least above a certain size (for oxudercine gobies,
approximately > 40% the recorded maximum size - SL or TL). A set of
characters to ID species in the field can always be found (or at least
desperately searched for... :-) ).
Forgive me, I also assumed that the person asking for identifications
was a scientist of some sort.
But having said that, the point that people can often identify fish
from photographs does demonstrate that in theory at least, digital
images may be adequate instead of dead specimens. We don't tend to
think about this with small animals like gobies, but for bigger
animals, particularly large mammals, it is standard practise now to
identify them by sight and sometimes even individuals can be
identified by its particular markings.
Of course, the flip side is that large mammal species are relatively
few, and they usually look very different; with small animals like
gobies, you can often have dozens of extremely similar species within
one genus. Our old friend the bumblebee goby is a prime example, and
while Naomi Delventhal was writing part of the brackish water fish
book with me, she commented words to the effect that virtually every
photograph of this fish in the hobby literature was probably
misidentified at species level!
A thought crossed my mind though about your "Hey guys, I caught a
fish..." comment. I wondered if in the life of every person who
becomes an animal expert, there's a phase in their life when they're
cruel to animals. What I mean is this: young children, as they develop
an interest in wildlife, often have little to no feeling for
conservation or welfare. Myself, I used to catch fish from rock pools
and streams, keep them in buckets, take them home, and in some cases
ended up killing them through neglect or misuse. As an aquarist who
writes about how to keep fish better, there were times when I wasn't
experienced and I wasn't keeping fish well at all.
In other words, there's cruelty and then there's cruelty. Animals are
cruel to each other, and the PETA-type approach, while viable if you
live a life far removed from animals, isn't particularly practical if
you're engaged with animal life at some level, whether as a hobby, for
farming, for conservation, or for science. But as others have stressed
eloquently already, the important thing is whether you learn to
minimise cruelty, that you try to move past it in whatever you do, and
that you see your interactions with animals as part of a bigger
picture where respect and understand are at issue.

Gianluca,
Your message was very interesting. Your decision to switch from using
cold to kill small fishes to using clove oil is mirrored by my own
practises.
Having kept very many fishes, I've inevitably had to deal with fish so
sick or injured they cannot recover. This is an aspect of fishkeeping
often overlooked (and misunderstood) by hobbyists. About a year ago, I
summarised "best practise" for euthanasia according to books and
papers written by vets, as opposed to rumours put around by hobbyists.
You can read the article here:
http://www.wetwebmedia.com/euthanasia.htm
One interesting thing about the use of specimens to identify fishes
(and animals in general) is that taxonomy has very largely moved on.
It seems to me that all the big research projects, and the ones that
get funded, are based on DNA, not counting bones or fin spines.
I have mixed feelings about this. Personally, having worked for a
while in a molecular biology lab, I found this approach extremely
dull. But I can see from the books and papers than genetics provides
far better resolution. You can define species more accurately, and
because the method itself is a bit "cook book" in approach, you only
need experts at the procedure, not the groups of animals being studied.
(In parenthesis, I know respected taxonomists who work in molecular
biology labs doing excellent work, but who also know virtually nothing
about the natural history of the animals being studied.)
People like Richard Fortey and Bill Bryson have written wittily about
the death of old school "experts" in particular groups. It's a very
sad thing for me, because I worked with some of these people when
doing my PhD and post-doc, and I loved the fact there were people who
spent decades studying one small group. They seemed to know everything
about their subjects! But on the other hand, the science has
definitely moved on, and animals and plants are often viewed as
sources of genetic material for study, rather than interesting things
in their own right.
But that, as they say, is a discussion for another day!
Cheers, Neale
I've had the same experience with microbiology. Nowadays the young scientists know everything about their genomes, but little about the organism. It's good that better and easier speciation can be done, but in the end it is how the organism lives and what it does that is really important.

Dennis

I fear science funding encourages this sort of thing. By focusing on
2-3 year projects, and by expecting young scientists to move onto
different labs (cities, countries) each time, the result is selective
pressure against deep *and* broad expertise.

I do agree.
Molecular biology is a useful tool to get insight into biological
mechanisms and processes.
Nonetheless, neither answers nor questions can be properly formulated
without a proper knowledge of the organisms at hand.
Being an ecologist, I would even add that a proper investigation of the
evolutionary and system ecology of whole communities in different
biogeographic contests is also needed if one wants to really try and
understand something of the organisms that form them.

True: fin clips per se cannot always tell us what species is the
fish.
Specifically, they can't tell whether the fin clip is of a species which
was only morphologically described.
To compare morphology and genetic markers we often need both, even if the
fast grow of genetic databases will possibly make this need gradually
less critical.
Nonetheless, in a first approximation (there still are problems), fin
clips can tell us whether a sample of 100 specimens contains one or more
species, both allowing us to make hypotheses on the reliability of
morphological descriptions, and to sacrifice a much smaller sample as a
reference collection for future studies.
I don't need to kill 300 specimens in a study site to show that only one
species is present in a putatively morphologically homogeneous sample: it
is sufficient to make a genetic analysis of 300 tissue samples (with a
good outgroup) and keep a few deposited specimens as a morphological
reference.
I think we should keep trying and find procedures to get morphological
data without sacrificing animals.
I mean, this is a routine procedure for many living organisms, man
included...
If the specimen is properly prepared (e.g. when it's anesthetized), high
quality digital images (X-rays included), can convey a great deal of
morphological information, some of which are often unavailable in museum
specimens (e.g. colouration patterns, some morphometric measures).
Furthermore, many traditional characters that are used by morphological
taxonomy and are not visible in photos can be of little use in some
groups (e.g. scale counts in Boleophthalmus spp., pers. obs.), and in any
case can be even more efficiently measured on anesthetized individuals.
Of course, you can measure only what you are observing. That is, what you
are looking for. If you want to make another measurement to dissipate a
doubt or because a second idea takes the place of the former one (which
in my case is almost the rule), and you don't have a preserved sample,
you simply cannot do it. If you work with live specimens all replicates
must be made during the first measurement session. Alternatively, another
sample must be collected... if you can afford it.
On the other hand, while I obviously agree that there are many
measurements that can be made only on dead specimens (e.g. anatomical
ones), certainly this is not the case of all scientific studies. And
certainly I am not talking of type specimens, whose usefulness is
apparent.
In my opinion, time and money are the biggest problems for a scientist to
spare animals' lives... it's much easier and cheaper to kill the guy and
do the work later, if and when the opportunity comes, than design complex
and expensive protocols. Just think that you usually have a very limited
time to finish all measurements after capture, and that each survey would
imply double costs and time just for the release of the examined
specimens.
Yet one point remains. Museums are repositories of the past and for the
future. Here modern information can be obtained from specimens that were
analysed when modern tools and equipments were simply not available. Such
specimens are in some cases of rare or extinct species, and are the only
remains we have to know something about them and compare them with the
present.. this point cannot be underestimated, and this is a vital
function that museums still have today, while species continue to go
extinct at impressively increasing rates (which are in most cases
substantially unrelated both to museum collections, and to taxonomical
research).

Oh, God.
I have received more than ten emails (messages) for this (and the previous)
topic!?
Can we stop arguing to kill or not to kill!? As all of us know, killing should
be the last but also would be the necessary protocol in fish identification,
especially when we meet an unknown species. Keeping a specimen in museum for
academic/ taxonomic purposes is also a must!
I think there is no point to argue any more.

I was talking of taxonomic ID for ethological/ecological studies: the
question is not trivial.
Some peer reviewed journals may even reject papers if ethical issues are
not respected.
And unnecessary killing is an ethical issue.

Hello Tony,
I couldn't disagree more strongly.
For one thing, this mailing list often seems nothing more than a
succession of photos from collectors who want experts to identify
their fish for them. This recent discussion has added some much-needed
variety.
Secondly, discussions between scientists and the public about this
topic are critical. In liberal democracies scientists are obliged to
explain to the public why they make certain ethical decisions. Last
week I was covering precisely this topic with regard to animal
experimentation in my History of Science class at Pepperdine
University. Scientists have no right to do things the public find
distasteful, especially where animal welfare is concerned. By
explaining why scientists do this sort of thing, the public become
educated and are more likely to be supportive.
The worst thing scientists can do in a liberal democracy is to shut
themselves off from the public. Some scientists think publishing in
journals is all they need to do. It most certainly is not! Mailing
lists like this Yahoo Group allow, in a small way, for the public and
scientists to interact. That's a fantastically constructive and
helpful thing for both sides.
If you don't want to participate in science communication, that's your
choice. But for science in general, nothing is more important. Without
the public supporting science through their taxes, science with no
immediate commercial value simply wouldn't get done. I'd hazard a
guess that most research on gobies is paid for by the taxpayer and not
by drug companies!
Cheers, Neale

Hi, Monks and Polgar,
Thanks for your explanation.
I think the point I don't really know is that this forum would contain a large
amount of (or some) non-fish scientists/ laymen (That's why at the very first
beginning I think there is no point to argue among "scientists" on the issue).
I totally agree with Monks that there should be more interaction between
"scientists" and "the public", so as to educate them (scientists would also
learn something through this kind of interaction).
I also agree with Polgar that unnecessary killing should not be done. Indeed,
as I said, killing should only be conducted when we really need a voucher
specimen to be kept in museum (or something like that).
Thanks god that we are all living in liberal democracies: allowing us to have
such a valuable discussion and to have interaction with general public from all
around the world, no matter from the east or from the west.

Tony Nip

In regard to your original post, I'm unsure as to whether you've actually been reading all the messages, as there has actually been very little true "arguing" but lots of welcome reflection and information on the issues surrounding the killing of specimens.
And about this being a discussion among scientists only - certainly not the case, as in terms of zoology, I'm just a tropical fish hobbyist who happens to really like gobies (I am doing an MSc in Consciousness & Transpersonal Psychology, but sadly there's no fish-study involved in that type of 'science'!). It's been very interesting for me to read about the perspective of scientists who actually do fieldwork and thus have to / have had to make decisions about specimen collection. I've been glad to see this kind discussion get going on a message board that, as Neal (I think) said, is usually just used for fish identification.
I have also been very happy to see that some of the scientists who have chimed in seem to have given significant thought to these complex ethical issues and don't go into the field killing indiscriminately, but rather with a reverence for life as well as science.
Also, Gianluca, if I read one of your messages correctly, you have devised a method of temporarily anaesthetizing small fish using clove oil? Or did you mean that when necessary you killed them this way?

Hi, Sarah,
I am also glad that you begin to understand the ethics behind, and give us a
chance to communicate on this topic.
To be honest, in our team, killing would only be the last protocol in fish
identification/ fish survey (and we seldom do). What we usually (now nearly
always) do is using underwater digital camera (UDC) to make records instead of
electrofishing/ fishing using chemicals (i.e. rotenone)/ gill-netting (as I
know, these are still regarded to be "standard sampling methods" in many
so-called developed countries, and are still frequently being used (you can read
more scientific papers and you can see)). Of course, UDC would only be useful
when the water is not turbid and in some cases, gill-netting would still be
employed. Nevertheless, our government has already banded electrofishing and
chemical-fishing.

Tony

I am also a fish hobbyist and have kept large catfishes (Red tail catfish, giraffe catfish and Oxydoras niger), lungfishes and bichirs. Catching them and moving them between hobbyist auariums over long distance can be problematic and often we would use anaesthetic agents to sedate them. With such large fish there is some error of margin in dosage but I would expect it would be quite easy to make a mistake and kill smaller fishes.

I meant I anesthetized them to spare their life.
That was the plan... and it worked.
No problem for the small size: it's only a matter of concentrations and
timing.
I also know a group studying the behaviour of "guppies"
(Poecilia reticulata) in Padova (Dr. A. Pilastro): they routinely use
MS-222 on fishes that are under laboratory observation. It also works
well, but it's maybe more difficult to find in some countries.

there is a mailing lists exclusively dedicated to goby specialists
(gobiidae@yahoogroups.com).
For some reasons, this one is mixed and much more active.
I agree with Neal that for the moment this makes this list even more
precious and useful.

Hello Tony,
Good to hear there's a consensus here. Makes this sort of discussion
more pleasant.
Forgive me for using the phrase "liberal democracy" in a way that
might have seemed I was trying to contrast values in one place with
values somewhere else. I was really trying to avoid saying, "here in
England..." or "here in the West..." since those sorts of things
wouldn't be appropriate to an international group like this one.
Have a nice weekend, all.
Cheers, Neale

Hi, Gianluca and Neale,

Thanks Gianluca for the new mail list and I will try.

With all this talk about to kill or not to kill I think that folks need to
step back a little bit and consider the broader picture. Many folks here
are aquarists (I'm a scientist and an aquarist), but in reality the
aquarium hobby kills more fish, in terrible ways that the scientific
community ever could. Consider fish like gobies, they are not suitable
for the average home aquarium, how many of them in the trade end up dying
terrible long drawn out deaths? They require specialized care that most
folks are ignorant about, or unable to provide. Indeed, I often tell
people that to become a good fish keeper you need to kill a lot of fish as
that is the only way that folks typically learn how to take better care of
their fish. Consider wild harvest of fish for food or the trade. From
what little I know most food fish do not die in a humane fashion.
Consider angling, how many people catch their fish, dump them in a bucket
where they suffocate to death.
I certainly don't advocate doing away with aquarium keeping, harvest or
angling. I would advocate that certain things could be done much better.
I also advocate that we need these things too because without people being
able to interact with fish then the justification for their conservation
and appreciation goes away. But I would also advocate that scientists
should be killing more fish too (in a humane fashion) because our museums
really lack good collections for many species of fish for most of the
world. Photographing fish is fine, and for some parts of the world with
very well known faunas there is little point in keeping many if any
specimens, but this is by far in the minority of places globally. But if
scientists are releasing all of their fish as part of their studies, and
the taxonomy changes later, without specimens it is likely impossible to
know what the actual species was that they were studying which devalues
their study in the long term. There is little point in keeping large
number of specimens of common and well known species, but few species are
well characterized taxonomically, or are that well known.
Cheers
Peter Unmack
Hello Peter,
I agree 100% with what you're saying here.
However, to play devil's advocate for a moment. One issue is that
fishermen are catching fish to eat; scientists are collecting fish for
no practical value.
Let me clarify this. I know fish taxonomy is important. I also know
that science is important. But most people see a difference between
useful science (e.g., finding a cure for cancer) and useless science
(e.g., determining if the genus Brachygobius is monophyletic or
paraphyletic). You can wave your arms and say, "Yes, but understanding
diversity is important, for things like conservation". But really, do
we need to know about how many species of Brachygobius there are to
understand chopping down rainforest and mangrove habitats is a Bad

I see your point, but I don't fully agree. Clearly though public
education and appreciation are important points. Fisherman will often
toss things like suckers (that lack "practical" value) on the bank as they
think they compete with trout, but once you explain to them that suckers
are actually a food resource for trout and that they are potentially
harming their trout by killing suckers they are more likely to change
their ways.

Sure, but governments don't base decisions on what to do simply based on
the premise that cutting down trees is bad. If they are going to spend
money on conservation (or tell people that they have to stop cutting down
trees) they want to be sure that they are hitting the most important
places, and hence spending public money as wisely as possible for the
biggest bang for the buck. You need biodiversity information in order to
make those decisions. Ecotourism is the same thing, folks want to go
where biodiversity is, they aren't going to pay money to visit a tree
farm.

I am away from my office and country (am using Brazilian keyboard) and reading emails intermittently.
Have just had a fascinated read-through of the most discussion that this group seems to have ever had. And it is interesting to see the different ways people perceive killing and using fish. I'm
one of those scientists who kills fish to study them or uses fish that were killed by other people (often 100 years ago or more) and put in museums. I also keep fish as pets - but nearly always wild-caught myself from local streams and rivers (a safe and permitted
activity in Australia) as often 'petshop' fish just drop dead a few days after you take them home (who knows what's happened to them en route).
The number of fish that I kill is very small compared to most fisheries for food, pets, entertainment etc - all the other reasons people take and kill fish. I do it quite selectively - unless I am using something
like rotenone, which is used if I am working in an area about which little or nothing is known. And even then, I have had fishermen come and look in the esky of ice at the bags of fish and say "Is that all you got? those little things?" or "Wow I had no idea
all those fish lived in that muddy/rocky shallow pool". Yes clove oil works as an anaesthetic - you can relax them and revive them or you can painlessly put them to sleep. But first you have to actually see the fish to get the oil close to them - not practical
at all in turbid tropical habitats where \i do much of my work.
And yes, some people just use this forum to get their fish photos identified by experts/scientists - but you should remember that a good scientist has learned the hard way how to identify fishes, and that is by examining
them very carefully, and if theyre gobies, which is what we really are talking about here - then we are faced with very small fishes that have many useful features that can only be seen using a microscope. I can identify many gobies just by looking, but then
I have been doing this since about 1966 which is probably longer than some of you have been alive.
There are not many people like me left - someone said that "taxonomy has moved on" - the funding has, yes, but I've seen a number of papers published using genetic analyses that came to some silly conclusions because
the fish were not identified properly. The worker took a guess, or looked at a photo and thought it the same, or believed an old identification label in a jar, who knows. These people did not check the identity of their specimens by keeping vouchers in a museum
and/or sending them to an expert to identify.
I guess the upshot is that I want to remind you that morphological taxonomy is not in good shape and is very poorly funded. Many of us who do this job do it because we are madly passionate about it. On the 20th of
this month I will be officially retired and no more salary. But I will continue to work on fish until I can't - just like several of my equally mad colleagues. The disheartening thing about the whole process has been the lack of carryover or chance to mentor
someone in my job. And I asked. More than once. No funding. No govt willpower.
So next time you send in a dubious photo of a goby, spare a thought for those of us who are willing to help you - the info in our minds has not just appeared there quickly.
Sorry for the long-winded post - but it was so good to see some real discussion going on between a very different miXture of people!

Hi Tony,
In regard to your original post, I'm unsure as to whether you've actually been reading all the messages, as there has actually been very little true "arguing" but lots of welcome reflection and information on the issues surrounding the killing of specimens.
And about this being a discussion among scientists only - certainly not the case, as in terms of zoology, I'm just a tropical fish hobbyist who happens to really like gobies (I am doing an MSc in Consciousness & Transpersonal Psychology, but sadly there's
no fish-study involved in that type of 'science'!). It's been very interesting for me to read about the perspective of scientists who actually do fieldwork and thus have to / have had to make decisions about specimen collection. I've been glad to see this
kind discussion get going on a message board that, as Neal (I think) said, is usually just used for fish identification.
I have also been very happy to see that some of the scientists who have chimed in seem to have given significant thought to these complex ethical issues and don't go into the field killing indiscriminately, but rather with a reverence for life as well
as science.
Also, Gianluca, if I read one of your messages correctly, you have devised a method of temporarily anaesthetizing small fish using clove oil? Or did you mean that when necessary you killed them this way?
-Sarah

Hi, Monks and Polgar,
Thanks for your explanation.
I think the point I don't really know is that this forum would contain a large amount of (or some) non-fish scientists/ laymen (That's why at the very first beginning I think there is no point to argue among "scientists" on the issue).
I totally agree with Monks that there should be more interaction between "scientists" and "the public", so as to educate them (scientists would also learn something through this kind of interaction) .
I also agree with Polgar that unnecessary killing should not be done. Indeed, as I said, killing should only be conducted when we really need a voucher specimen to be kept in museum (or something like that).
Thanks god that we are all living in liberal democracies: allowing us to have such a valuable discussion and to have interaction with general public from all around the world, no matter from the east or from the west.
Regards,
Tony Nip

Hello Helen,
It was I who said that "taxonomy has moved on". And I agree with you,
yes, that's from the perspective of the money.
My PhD and post-doc were in morphological taxonomy. I was working on
heteromorph ammonites -- among the least useful animals to have ever
evolved on this planet -- and all my work was done "by eye". After six
or seven years, I got pretty good at identifying some pretty shabby
bits of fossil! But as much as I enjoyed doing this work, and running
cladistic analyses based on the data I was collecting, it was crystal
clear to me that this was a dead end. There is little/no money (i.e.,
research grants) in morphological work, at least not by itself.
Those young scientists I know working in the field, including one
friend who works on cichlid taxonomy, all work either partly or
entirely with genetics.
I have know serious museum administrators who talk about shipping off
all the specimens to warehouses somewhere, and simply concentrating on
"the big picture data" instead.
I cannot begin to tell you how much I respect the kind of work you do,
and all those other "old school" taxonomists I've met over the years.
There's a level of enthusiasm *for their pet animal group* that seems
to be missing from the younger generation (i.e., my age, and I'm 38).
The younger scientists -- who were much better and more successful
than me -- all realise that it's the funding, not the subject, that
matters.
Yes: you are absolutely right about how people take for granted the
skills of museum workers the world over when it comes to identifying
material. In my own field, it is telling that most of the key ammonite
stuff was written pre-1980, and a lot of it pre-1950. I seriously
doubt that the sort of people who could write a monograph exist today,
at least, not under the age of 50.
Cheers, Neale
PS. For those who have no idea what a heteromorph ammonite is, I have
some of my drawings of them on my web site. There are a few papers
online there, too.

There is a long way to public understanding of the meaning and utility of the biodiversity thinking. But if this is true and therefore worthwhile, we should never stop but to strive in whatever little way or long time to go for this course.
See some change in accurate and serious popular science writing can do in the last 30 years. We shall at least have some hope.

Hello Peter,
I agree 100% with what you're saying here.
However, to play devil's advocate for a moment. One issue is that fishermen are catching fish to eat; scientists are collecting fish for no practical value.
Let me clarify this. I know fish taxonomy is important. I also know that science is important. But most people see a difference between useful science (e.g., finding a cure for cancer) and useless science (e.g., determining if the genus Brachygobius is monophyletic or paraphyletic) . You can wave your arms and say, "Yes, but understanding diversity is important, for things like conservation" . But really, do we need to know about how many species of Brachygobius there are to understand chopping down rainforest and mangrove habitats is a Bad Thing?
I hasten to add: this isn't my point of view at all. But it is a common viewpoint in the public at large.
Cheers,
Neale

Hi fellow members! I've very much enjoyed following this conversation. It's good to know that everyone has these ethical questions in mind while they persue their scientific objectives. I'd like to give a big thank you to all those that take the time here to help hobbyists like myself identify and better understand the fish we keep. It really is a great resource! I'd like to share a few very interesting videos that have recently come up on one of the forums that I frequent.

Very cool videos! Thanks for sharing.
A general question: did gobies evolve their sucker-like pelvic fins in
the sea or in freshwater? Does the fossil or genetic record help
answer this at all? I'd be curious to know whether their suckers were
for helping to resist fast flowing streams (as here) or for holding
themselves in place in shallow marine habitats, as is often suggested
in marine biology textbooks.

Contact Michael Hammer "michael at bold dot net dot au" he is working on
Australian goby genetics and will likely have some samples that he is
potentially willing to share.
Folks at the Australian Museum and the Museum of Victoria may also have
ethanol preserved material too, but you should probably double check any
identifications.
