Just to add in my 2 cents, we had GSH put in our pond the spring of 2018, after stocking new LMB, to help boost growth and take some pressure off our BG population as our forage base that spring. We still see adult GSH, and occasional catch 7 to 8 inch adults on small jigs. This spring, the ones I caught were fat with eggs. However, if I recall my reading, all those adult females are sterile by now, correct? Something about a parasite that impacts the ovarian function of the females? So the adults can still stake claim to some of the food chain (small fish, eggs, etc) but are no longer contributing new fry?
