Supplier told me they grow fast to 12-14 inches and then it takes several months to gain more length. I am more interested in them putting on weight.
When you say they grow fast, is that length or weight or both? Thanks.
I put in 10-12 inchers in early December, probably averaged 0.8 lb. By mid Feb they were 16-17 inches and were around 2 to 2.25 lb. Then they paused in growth for about a month or so. Finally ended up around 3 to 3.5 lb, 18 to 21 inch max in late April early May. Gone by late May.
I don't aerate, so my thermal refuge is pretty good until anoxia sets in by around mid to late May.
