Buckeye -- I thought it would be a tough question to answer, especially for the small fish. My thought was thin fish = too many, problem to manage. Plump fish = young fish that likely are still growing fast. If you had some way to get a weight on the fish, such as grams, I probably could give you some interpretation. You'd have to find a pretty good quality scale.
