I plan to soon start raising some catfish once my system is cycled. It sounds like with catfish, you cant keep a population going in the tank because they will eat their fry. I think im going to keep one or two small fish tanks inside to keep a couple breeders in, for when I need to restock my main tank with young. I plan to breed the top fish that have fastest weight gain, hardiness, etc. I would think that if only siblings were bred with one another inbreeding problems would appear.
Because of that, I was thinking of using a family breeding method. So lets say I choice 10 of my best fish and divide them into two groups of 5 (group A and B). Then each group would be bred and produce pure B offspring and pure A offspring. From then on, A males would be bred with B females, and B males with A females.
Do you think this method of breeding would work okay with my fish? I was thinking of doing it this way because I don't really want to have to get new fish to introduce to the lines, but also don't want inbreeding problems.
Im interested in hearing the methods of breeding that people use with their fish
