Please do. I am interested in knowing the schools you studied and the classes you took. Biology(especially marine biology and the study of piscivores), physiology, piscivoric anatomy and necroscopies are demanding areas of study. To become an expert in such areas would take a great deal of discipline, dedication, time and money to attend schools that offer such advanced areas of study. They are not something that any lfs employee can pick up on the sly or from just reading a book on the subject(s). A great deal of teaching from highly qualified professors and listening to lectures given by such minds, and lab time would be required. Having a microscope in the fishroom, a reference book at hand would not make one an expert in the field.
Hundreds, if not thousands, of post mortem autopsies would have to be taken and a controlled experiment and environment would be needed. Biopsies taken and examined, data gathered, archived and processed, it would take years and years of experimenting, collecting the data and processing the information to make such a claim. Literally feeding fish highly regimented diets, all monitored and varied, in order to kill them to collect the data. I don't believe that happened here. I will stand corrected if wrong and admit being so, but I would have to see it to believe it.
