[Fish for Aquaponics]

Perch are a pest fish and therefore it is illegal to posses live specimens.

In New Zealand options are very limited. Goldfish are a possibility (I don't imagine they'd taste very good though) Tropical fish are another possibility, maybe oscars? Another option would be mullet, not sure if this has been attempted yet.

[Fish for Aquaponics]

I am in the process of setting up an aquaponics system and would really like to stock my system with an edible fish variety to provide food for the table to go along with the vegies it will produce.

The choices available seem pretty limited however perch would make a great option. Does anyone know where I could purchase some fingerlings or junior fish?

If not, is it possible / legal to catch them from natural waterways? I am in Southland and I believe they are in abundance down here. Can anyone point me in the right direction for learning how to catch, care for and transport them?
