Pond Boss Forums INTRO Questions & Observations How big is too big for cast net?

I used a cast net quite a bit in the ocean for bait, then I started using it in my pond to catch BG to transplant in other ponds or use for big catfish bait in the river. Pretty effective, but I learned I need to stay away from the spawning beds. Very productive, but I can only imagine what I am doing to my breeding base.
