Ponds :

I think you can raise cats in a small pond if you keep a strong forage base of BG and tilapia and don't push the pond's carrying capacity. Will the numbers of cats above be small stockers or larger fish? You may want to do a search on carrying capacity to see how many pounds of fish a pond can support per acre.

A friend who is a fisheries science professor managed an isolated (a few miles from campus on univ. lands) BG pond (10 acres I think) that the university used soley to raise BG for stocking other ponds and for classes to seine and do studies. After a few years the students reported that it was getting harder to catch BG and seining results were falling. He checked it out and did not find an answer. They drained the pond and found a low number of BG and a couple dozen larger flathead cats . One over 60 lbs. a few at 25-30lbs and the rest from 5-15 lbs. Someone had been adding FH cats and using the university pond as their own FH cat growout pond. They never found out who or how many had been put in -grown out and caught and removed but he was serious in his warning about FH cats being serous predators.
