Aguita, I think I read at a fisheries web site that HSB have a maximum life expectancy of 7 years. So they recommended a laddering of them. The second event seems consistent with that life expectancy. But it is not clear if the first made it to 6 years in the pond. If you could be satisfied with limited age in the pond (5-6 years max), the HSB showed they could live to that age, then consider a ladder program if you enjoy them.
