CC should be able to control HBG F2 numbers.
george can confirm this, but HSB should survive in a small TX pond through Summer if you don't stress them via fishing when the water is warmest (george cuts off HSB fishing at 80 or 85 degrees). IIRC, he has reported a size wall for his HSB at 4-5 pounds.
The pond is 16 feet deep, right?
We have been successful in growing out HSB in our � acre pond for the past few years w/o aeration in record breaking Texas heat wave.
Last fall we transferred to main pond about 50 HSB ranging from about 1.5 lbs to ~4 lbs. Thought we had them all out of the small pond but last week caught and released 3 in the 3lb range.
Theo is correct that so far maximum wt for HSB have been in the 4-5lb range but we lost our biggest HSB last summer in a fish kill that also wiped out LMB, CNBG, CC and GC. I was expecting to break the size barrier this year with those fish.
We stop fishing for HSB when temps hit 80+ degrees as Theo mentions.
They will fight �til they die anytime unless landed quickly and resuscitated.
They are a blast on fly tackle.
A word of caution � HSB less than ~8 inches are expensive fish food if stocked in a pond with mature LMB.
