Isn't there a small shark? that does that plugging thing only with a larger plug? The cookie-cutter shark? I'm afraid if a species can't survice that type of damage they wouldn't last long in the ocean.

One Phd said you don't get anywhere in biology without homoginizing a lot of dog brains. Beagles are usually the preferred species.

I did my bit for better treatement of test animals I helped program the "whole rat counter" and "whole dog counter" for Nuclear Data, Inc (now Canbera). Used to be you dosed the animal with whatever you wanted to study (say iron uptake in the liver) then you "harvested" the animal, puried the organ and ran it through a test to check for iron. With the whole animal counter you added some radioactive iron to the normal iron and then shielded the rest of the animal and counted the area around the liver using an external detector.

Allowed the animal to be used in multiple studies. I guess that was more humane...

Good information Rocha.

I'm not sure what the fishing regulations are in U.S. waters, but they can't be too strict. I'm still seeing alot of Orange Roughy at the supermarket, and I'm 600 miles inland. I believe its been known for a long time that it takes these fish 30 years to reproduce. So are Roughy populations just going to be fished until they collapse?

No, regulations are not very strict! And scientists are always suggesting measures that err on the side of safety. But everytime we try to do something about it the fishermen come back with arguments that we have no data to prove that these populations are collapsing (even though the total catch has been decreasing and the fishing effort increasing). It is really a vicious circle, fishing lobies and most fisheries agencies won't accept incomplete data to establish fishing regulations, and that requires money and effort (for a lot of species).

But the big problem is that instead of just ajusting to the quotas, the commercial fishing industry just changes the target to a species that is not in the spot light and the circle begins again (because there is no data for that species).

Yes, that's exactly right, the cookie-cutter shark (Isistius brasiliensis) is a species distributed world wide that feeds on cookie size pieces of dolphins, whales and larger fish. It bites the dolphin and rotates to remove the piece, it is common to find marine mammals with bite marks. The sampling of the dolphins with the hollow point sampler is not harmful (oh well, maybe it is painfull but it doesn't have lasting effects). The problem is that those pieces are usually used for genetic research and scientists have to be very careful not to sample the same individual more than one time, or that will mess up the statistical analysis.

Deep benthic fisheries suffer far less regulation for one basic reason. They tend to be new fisheries.

Orange roughy (slimeheads), Chilean sea bass (patagonian toothfish) and other deepwater stocks are very poorly known compared to a well-established fishery. Lacking sufficient data to formulate regulations, no regulations are going to be made until that data is compiled... and bumped up to the management level... and then attempted to be placed under a regulatory regimen. It's a long drawn-out process.

Orange roughy fisheries are rather interesting. The species congregate around seamounts. Boats target individual seamounts and fish them till the fish are locally extirpated. Then the boats move on to another seamount. This "clearcutting" approach isn't unique to orange roughy or even deepwater species, but it is particularly susceptible to animals with low regenerative capability.

Which is indicative of many (large) deepwater fishes, and lots of large fishes in general.

Thanks for the summary of the species management/lack of data cycle -- nice, clear way of describing it. Similar sorts of cycles are seen in other industries as well, from energy to agriculture. I agree that a big key to controlling these cycles is who has the power to assign the burden of proof. Until there is a big policy change in that regard, the coupling between research and policy will be pretty weak.

But speaking of research and policy, where are we in the process of shifting fisheries management from focusing on species statistics toward considering ecosystem characteristics? I hear a lot of talk about that in MPA literature and in various "state of the ocean" reports to govt. bodies, but I don't get any sense of how much that is actually affecting management policy.
 
The "coupling between research and policy" has always been weak, and will continue to be weak till the end of time. Scientists do research. Politicians make policy. The two rarely mix well, particularly considering how incompatible the scientific method is with the thought processes of untrained people.

Ecosystem-based management has been around for a long time, if under different names and titles. I believe it even predates species-based management, at least from terrestrial examples. Most species-based management systems are actually ecosystem-based ones from a functional perspective. Which is why you're not seeing much change in management policy. In many ways it's little more than another layer of lingo being thrown around... a lot of cool-sounding stuff is getting said, but close inspection reveals that little of it is anything new, at least to trained biologists.

But people like the idea of "new". Particularly politicos. Case in point, our department wanted a new greenhouse. We couldn't get funding approval for it, because there were greenhouses plastered all over campus. They were humdrum... BORING... What good would another one do? No problem, it'll just get renamed a "genetic growout facility" (I forget what we actually called it). POOF! Instant funding for a brand new greenhouse. Nothing "new" is really being done there, but its still important work. That work wouldn't be going on if not for a little twist on words at one small moment of time.:)

Back to habitat conservation:
Heck, a lot of protected wildlife areas around the world were placed into such status simply to safeguard one or two "threatened" species. Or were they? Sometimes you have to ascribe more than a bit of deviousness to conservation scientists. WINK WINK.;)

Pelagic fisheries are tougher. Ecosystem-based approaches won't work well, 'cuz your ecosystem boundaries may comprise an entire friggin' ocean basin. Target species may not even have fixed enclave areas. It's a big pain in the butt.:mooner:
 
Interesting observations archman, but I don't understand why you're being so dismissive. Examples of poor mixing of policy and science may abound, but the two are still interdependent. The mechanism for making science based policy isn't anywhere near perfect, but I think it makes more sense to do what we can to help improve it than to just throw up our hands and say it's busted "till the end of time."

I was involved in the designation of several MPAs in Puget Sound quite some years ago, and as near as I could tell, the Dept. of Fish and Wildlife based their decision-making mainly on two species: fishers and divers :) More recently, their efforts have been directed at creating a network of MPAs that interact in a way that makes some sort of big-picture ecological and oceanographic sense. I seriously doubt that they were really doing the same thing the whole time WINK WINK but making it look like 2 different processes because in the earlier days they weren't collating the same sort of data as part of the decision making process.

And I'm baffled by why you say that ecosystem-based approaches to MPAs won't work for pelagic fisheries. Sure the boundaries may be an entire ocean, or more. You don't have to make the whole ecosystem a harvest refugia. Haven't gains been demonstrated by protecting/restoring spawning grounds, setting seasonal limitations, protecting nursery areas and areas where prey congregate, etc.? Aren't these examples of considering ecosystem characteristics in policy decisions?

And even if marine biologists have always thought in terms of the ecosystem and it's only the policy makers who are finally catching on, isn't that a potential step in the right direction? Might not the political acceptance of an ecosystem perspective make it easier to obtain resources necessary to better implement studies of same?

But as I said before, I don't know what's going really on, but I'm trying to understand it so that I can be more helpful than destrictive when I shoot my mouth off.
 
Please forgive me for this essay addressing (I hope) your questions, stillhope. I didn't have anything to do, and enjoy hearing myself talk.

That last statement was never inferred by me at any time. Please do not confuse the difficulty of being able to do something to equate with not doing it at all. But if you operate in the sciences and your work is directly relevant to any form of policy making (which is a VERY small subset of science, incidentally), it is commonplace for policy makers to ignore or be highly selective in how they view data or scientific advisories. Usually the former (ignore). Extra steps are typically required by scientists if they want their information to have a *reasonable shot* at making it to the policy level. These steps include tailoring research objectives to meet policy objectives, locating the relevant intermediary management personnel AND establishing a strong working relationship with them, and THEN having the good fortune of your research to be completed and key highlights submitted to policy makers (with proper middle management endorsements) at a time which the research is *politically convenient* to broach.

Basically, it's a lot of extra work that more often than not gets the luck of the draw at endgame. Which is one reason why only a teeny tiny ratio of scientists involve themselves directly in it. Government scientists often have to, but they're a minority.

**As an aside, the MAIN reason most scientists don't involve themselves in policy is that their work has no direct bearing on political decisions and they could care less. ** :D

Key points here.
1. Dept of Fish and Wildlife. Government agency whose scientists perform specific objectives in accordance with government policies. This is the tiny minority of scientists that actually are involved much with policy decisions (its in their job title).
2. Yes, the hallmark of ecosystem-based approaches is integrating (collating) different sorts of research all together. The difference between this approach and "classical research" has less to do with science than it has to do with data management and inter-lab cross-communication. Which isn't a paradigm shift in *science*, but in how that science is used. Only with the advent of compatible computer databases has this management tool become viable.

And I'm baffled by why you say that ecosystem-based approaches to MPAs won't work for pelagic fisheries. Sure the boundaries may be an entire ocean, or more. You don't have to make the whole ecosystem a harvest refugia. Haven't gains been demonstrated by protecting/restoring spawning grounds, setting seasonal limitations, protecting nursery areas and areas where prey congregate, etc.? Aren't these examples of considering ecosystem characteristics in policy decisions?
This argument is dependent on how the term "ecosystem management" is defined. It is very easy to confuse it with habitat management. Habitat management is the cornerstone concept behind the majority of wildlife protected areas. Habitat is a term linked to species, not ecosystems. And if one peruses the long list of protected wildlife areas around the world, it can be easily seen that such areas have an overwhelming bias towards habitat protection centered around target species.

Therefore, the ecological consideration of the target species is the sum goal of protective legislation, not the ecosystem. It just SO HAPPENS (here's the wink wink part ;)) however that a great deal of species protection can't take place without protection of its habitat. Which in essence, protects the ecosystem wrapped part and parcel with that habitat.

Some ecologists have referred to this quirky situation as "the ends justifying the means". Accurate, if not somewhat tacky. :)

With pelagic fisheries, classical "habitat protection" is problematic. Sure aggregation areas can be set aside, but animals don't stay there throughout their life history. Therefore only portions (and small ones at that) of habitat can be protected. Then there's the "irritation" of deciding which fishery species *deserves* priority on habitat protection. Remember, we can only protect little pieces of pelagic habitat. A spawning ground for some species may be little more than migration ground for others. If that same species doesn't have its other main aggregation sites protected, the point of protecting the spawning ground is moot. Heck, some species may have aggregatation areas that MOVE from time to time. Dang, what a regulatory mess!

Which is why pelagic fisheries have such complicated regulations already in place. Catch limits that vary by season, area, and species. Fishing grounds that go off limits periodically. Gear restrictions. There's good reason that "fisheries" is a science major all to itself in some universities.:11: I think Luiz on this board has one of these, in fact.

Therefore, an ecosystem-based approach sounds rather corny when applied to pelagic systems. About the only *new* thing that can be done (other than setting aside vast tracts of ocean) is integrate life history information of as many species as possible into one big management plan that focuses on points of commonality between large species groups. Example: locating a "super-species feeding ground and making it the hell off limits". But this work is already being done. God bless modern databases!

And I'm being overly simplistic regarding marine organisms. Many of the non-pelagics have pelagic larval stages. Corals, crabs, urchins, blah blah. Makes for a management nightmare, Bleah!

And even if marine biologists have always thought in terms of the ecosystem and it's only the policy makers who are finally catching on, isn't that a potential step in the right direction? Might not the political acceptance of an ecosystem perspective make it easier to obtain resources necessary to better implement studies of same?
Spot on! Throwing around these newfangled terms is "cool and exciting" to politicos and the lay public, which means (hopefully) funding and enhanced habitat protection. Only now it's called "ecosystem protection". ;). A lot of coral reef and hard bank MPA's fall into this new pattern of environmental management.

Protecting the marine environment isn't easy by any stretch. Bringing in different approaches like "ecosystem-based management" doesn't hurt and it has the possibility to do a great deal of good, particularly regarding funding and researcher collaboration. It's just that the science isn't changing much, just the way that that science is viewed. Go back 60 years, and basic ecology wasn't even on the radar of politicians. Go back a century, and public thinking of "nature" was a negative!

Public perception of the environment always lags far behind that of the (relevant) science crowd. Which doesn't make it any less important for the public to know *new* things, it just might not be viewed with the same excitement by dorks like us. After all, whatever gets disseminated into the public probably took 5-20 years of prodding by researchers to get there in the first place. Ha ha.

Oh, and every biologist and ecologist has their own opinions on this. I'm sure Luiz or DrBill will ream me for it for something outrageous I said. It's the *duty* of scientists to professionally ream out one another.:blinking:
 
I have similar feelings about beach seining. I was encouraged to do it once for research purposes, but decided against it due to my own ethical stance. Though I didn't choose to contribute in that way, I'm sure the data it creates is very useful- I just don't want to be a part of what it puts the fish though.
 
It's been a while, but I'd like to return to this conversation.

ME (today)
What I don't understand here is why you seem to be considering only a tiny subset of the intersection between science and policy -- the part that occurs directly and during the career of the scientist. Policy decisions are made every day that rely on (or ignore) research results by people who have been long dead. It sounds as if you're saying that the only science that counts is contemporary science, though evidence to the contrary abounds. The fact that I can post messages on the internet is but a single example of very intricate and extensive interactions between decades of science and decades of policy. Whether a scientist considers future potential of policy ramifications of his work or doesn't isn't really related to the discussion I was attempting to provoke.

Much science is directed (and funded) by agencies full of politicians with specific agendas (e.g. ONR, NSF, ...), even though the science may be basic or applied and the agendas may be short term, long term, narrowly or broadly focused. It's all over the spectrum. The policy makers don't have to think like scientists or mix with scientists in order to reap the benefits of the science.

In the end, the policy makers and their constituency are responsible for harvesting from the research results those gems of knowledge that will improve their insight and make their decisions better. They can find a way to do that if they want to -- the question I was raising was more about their motivation.

The point I was trying to make originally:
"I agree that a big key to controlling these cycles is who has the power to assign the burden of proof. Until there is a big policy change in that regard, the coupling between research and policy will be pretty weak." [5 Jan]

was to abstract what Rocha was saying

"But the big problem is that instead of just ajusting to the quotas, the commercial fishing industry just changes the target to a species that is not in the spot light and the circle begins again (because there is no data for that species)."

to say that the burden of proof needed to be changed. Our legal system says a person is innocent until proven guilty -- that defines the the burden of proof. In the case of these fisheries, the burden of proof does not lie with the harvesters -- if there are no data, they have a field day! To use a specific example, fishing regulations in my area are also prohibitions -- anything not prohibited is fair game. A few years ago people started catching sixgill sharks. It took a huge hue and cry to get Fish & Wildlife to say, "gee, we don't know much about them, maybe we should ban sixgill harvest until we know more." Now if harvest were only allowed when one could show that it would have no detrimental effects, then the story would have been entirely different. We might actually still have the biodiversity that was common only a few decades ago.

I was just reading the 2003 report from the Pew Oceans Commission. They said pretty much the same thing:
1) change the main priority from harvest to conservation
2) separate conservation and allocation decisions -- don't allow the same agency to do both. The FDA is another example of this principle gone amok.

Of course, not everyone would agree to this, and what will really happen is likely to look more like a compromise. But I was trying to paint the target!

Anyway, sorry for all the words, I didn't have time to say this using fewer :-)
