I’m a little confused still are Catfish at this pond Catch and Release or can you keep them and same question for Bluegill and Crappie?

They are all catch and release. However I have seen people take them home.

Only the big mouth bass is catch n release..limit 3 on the catfish and bluegill and others

Yes, all of the above.

All fish in the pond are catch and release

Don't know what type of fish are there but it is supposed to be catch and release.
