I can't help you with the ID of the bump on the head but I'm impressed you could harvest 35 adult CC at one time. What is the secret for harvesting them?
These catfish are fed twice daily. They are in our hybrid Bluegill pond feeding very well on them. Busting them in the middle on the surface. I set 3 rods using small goldfish, circle hooks with drag off.
I transferred about 10 to pond I hope they will spawn in next season. I did not put any with odd bump into the hatchery pond. Thinking maybe a tumor or cyst.
