Lady of the Lake: Figuring out fish kills
A “fish die-off” is generally a natural phenomena and occurs in summer when low oxygen and warm temperatures causes large mortality in a localized population of fish. Fish die-offs can also happen in winter months when temperature stress can kill a fish population. We have seen winter die-off happen during extreme winters here in Clear Lake and her tributaries, especially to the fragile, small bait fish populations like the threadfin shad and silversides.
