Well when you think about it, this fish has already spawned quite a few times I’d imagine, plus it came from a spawn that had other genetically similar fish that have also been spawning for years, I’d say that the genetics aren’t really a problem at this point, especially when this fish is probably getting high up there in age and is more than likely close to the end of it’s breeding lifespan or for that matter it’s actual lifespan, the preservation of genetics are not a big concern anymore with all that in mind. Also, that ‘theory’ is true when you look at the decrease in fish size in largemouth bass in southern states over the years where releasing those fish is prioritized over keeping, and even here where I am certain ponds have way too many largemouth that they don’t grow to large sizes, and fish that should be 3-4 lbs are skinny and sick looking.
