Fish


Fish will become an integral part of the garden as time goes by. At the time of writing this, we have 11 goldfish (Carassius auratus) in the big green tank of the aquaponics. They keep algae down, give me lots of fun watching them and their wastes feed the plants that we eat.

It’s a nice loop but we can improve it. In a small tank in the lounge so that I can watch and learn about them are 10 Silver Perch (Bidyanus bidyanus).

Silver Perch are pretty well the standard aquaponics fish in this area. They handle the lower temperatures over Winter and grow to a good eating size.

They’re a bit pricey (over $5 a piece for fingerlings) if you get them in small numbers from aquarium shops. They’re cheaper if you buy them from the local aquaponics supplier, but he sells a minimum of 50. That’s too many for our system.

Once the weather gets Warner, they’ll go into the new tank, separate from the goldfish for a while until I’m sure they’ll still survive.

Folks say that the Silver Perch will eat the Goldfish, so maybe we’ll have to keep them separate.
