i usually fish in a creek that runs by my house for small mouth bass, well i recently asked a feller if i could fish in his pond. He told me i could try but there wasnt any fish. Well i went anyway and caught about 20, they were about 9-10 inches long i think they were black bull heads, well any way after we began skinning them there were little yellow worms around thier fins... is this normal? can you still eat the fish. also i just wanted to say hello and about what lb test line do you use when fishing fo big cats at bullshoals?
