I think those waterfowl studies are mostly interested in movement but I’m not 100% sure. On the Horseshoe study the main purpose is to look at what percentage of tagged fish are harvested. This helps us determine if a minimum length limit will be appropriate. If harvest is too low, fish will become stunted below or right around that length limit. Not sure if it will work but here’s a link to an article that D10 wrote that explains length limit use for crappie.
