Pond Boss Forums INTRO Questions & Observations New Fish Cage Designs?

Russ I think some 3" yellow perch will swim through 1/2" plastic mesh esp if they loose some body weight. I would trust 1/2" mesh to contain uniform sized 3"BG but not 2" BG which have a body height of 15mm +/-. 1/2" mesh on the diagonal runs about 15mm and assuming there are NO gaps in the cage seams. I have measured a skinny 3.1" YP as having a 14mm body height.
