Still in Arkansas, but away from the food industry, I visited the University of Arkansas. At least, I intended to move on from agriculture but got caught up with the Aquaculture/Fisheries Center.
I now know that fish get sick and die for a number of reasons such as bacteria, viruses, parasites, environmental and man-made toxins, and poor water quality. The Diagnostic lab at the university can tell you why a fish died but there is an art to collecting the right fish to take there. Freshly-dead fish are not preferred as they are very inferior to live sick fish. However if the freshly dead fish has clear eyes and red gills they could be okay, for analysis that is. I would not suggest eating.
Catching a sample selection of fish from a lake is haphazard.
Catching with a line is useless as only healthy fish will feed. There was a cute drawing showing the odds of catching (using a number of fishing lines) four sick fish swimming with about forty healthy fish was zero in ten.
What I learned that was special:
• From a technical standpoint, freshwater shrimp can be raised in Arkansas, but it is not clear if doing so will make any money.
