Fish Farming For Self Sufficiency In My Pond?

Considering I have a pond, deepest is 18 feet, about 140 feet long, on average 30 feet wide. I have large mouth bass that I sport fish for and release back into the pond. So why not put and feed some fish that I can harvest later on? I am considering crappie, yellow perch and catfish. I am also looking into some lake trout as well. Its just a new way I never considered in quest to being self sufficient.
