I had the minnow trap out for 3 days (checked it every 12 hours or so) and only thing I got in it were the small bg like pictured and a salamander so I may have been mistaken on the minnows. So as of right now I know there are two size classes of bg, 1-1 1/2" and 4-5", and all of the lmb I've caught have been in the 7" or 10-13" range. My theory is that when the pond almost dried up over the 2008-2009 winter, only the spawn of that year surivived, whether due to low oxygen or the larger ones being fished out. That could mean last year would've been the first year they were large enough to spawn, so there are two classes of fish in the pond, the three year old fish and the fish that were spawned last year. Does this seem feasible based on the sizes of the fish caught so far and if so, is it best just to let them be for now to see what happens?
