Ponds :

Send me the paper at my email above and I will take a look and report back.

I have read hundreds of studies and can state that they each one has to be examined closely and often one can not infer very much or far with their conclusions. One difference I always note first is was it from field studies or in the lab. In some studies that alone can make a world of difference. It is next to impossible to compare results form one fish species and extrapolate its results to another species that it is not closely related to genetically. Unfortunately some studies are written with a purpose in mind to advance an idea for reasons other than science. For what its worth one very good fisheries text has a chapter on how to look at studies and how they were set up to see if they are valid or not. Most good fisheries organizations have very tough and stringent peer review before they can be posted. I have even found papers that were well planned and subject to the strictest peer review from excellent fisheries scientists that found opposite results which can not be explained.
