Think of the words biomass and dissolved oxygen crash. A body of water can only hold a certain # of pounds of fish. That's the biomass. It's a matter of the dissolved oxygen that will support the population. Crappie, bluegills and bass spawn and over spawn in a 1/2 acre pond.

Bluecats, when the get bigger, need big food to sustain themselves.

So, to have BC's, you have to have a lot of large prey. But to get there, you need a LOT of fish turning into big prey. That leads to the dissolved oxygen problem.


It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
