Are you keeping your fish feed outside?

Storing fish feed near the fish is convenient, but in the hot summer the feed can go off.

I’ve had a case where salmon feed was not stored in an insulated shed, and one hot summer in Tasmania (yes shockingly, Tasmania can get rather warm!) their fish started dying in numbers. Down the microscope, I saw hepatic necrosis and some saponification of adipocytes. Deaths abated once new feed was brought in to replace the ones that went off.

So this summer, make sure you keep your fish feed stored properly.
