I am not sure of the low temperature tolerance of HSB. It is feasible that aerating too much all winter lowered the water temperature enough the HSB died. Do you pull the diffusers into shallow water for winter aeration? Cold water of 39F and <39F mixes very easily and even regular aeration moved to shallow water can have big influence on a large area. The striped bass genetics from the marine habitat of the hybrid I suspect is not well adapted to water less than 39F. Prolonged cold water stress may have contributed to death of your HSB.
