1 DR. COOPER: I have a very strong feeling here that we are not 



2 writing these short 100 words here for some peer view science journal; 



3 it is for the general public. I think we want to be careful not to 



4 nitpick the total accuracy or all fired concern about whether there are 



5 exceptions. 



6 If we do these studies in another 10 or 20 years, we will find an 



7 exception to virtually everything we have said here in the last day and 



8 a half. If there are some species that are--that are what, that 



9 are-'I'm not sure what the word to use is here. 



10 DR. VALENTINE: Not the "U" word. 



11 DR. COOPER: There are species that are relatively distinctive-- 



12 DR. HECKER: Yes. Can I qualify that even more? In the North 



13 Atlantic. 



14 DR. COOPER: Primarily found within canyons. Then I think we 



15 ought to make that point. 



16 DR. HECKER: Yes, in the North Atlantic. The Mid-Atlantic shows a 



17 different pattern, so if we want to put our qualifiers in, let's put all 



18 of them in. 



19 DR. COOPER: The tile fish is a classic example. Virtually all of 



20 the tile fish populations that I have seen or heard anything about are 



21 strictly canyon populations, but there are one or two very small 



22 isolated fisheries, for whatever reason, on the outer shelf/upper slope 



23 environment where these tile fish occur. 



24 But, that wouldn't stop me, just as one participant in this 



25 workshop, from making the statement that these tile fish are primarily 



26 unique to canyon environments. 



27 DR. VALENTINE: Couldn't you say that these species are 



28 concentrated in the canyons? I mean, after all, if the upper slope at 



29 comparable depths had the same habitat diversity, they would be all over 



30 the upper slope, but they are not because the habitats are different, so 



31 they are concentrated in the canyons, although they can live on the 



32 upper slope if they find a boulder or something to attach to. 



33 DR. NEFF: That's the obvious thing, the substrate availability.
