Special care needs to be taken when moving fish in order to minimise their stress levels and thus prevent unnecessary deaths.

Produced on a small scale, this includes cold-water pond fish, such as koi carp, as well as tropical fish.
Most freshwater fish farms in tropical Africa operate with minimum investment and infrastructure. Despite this, many are doing well. What, then, defines ‘success’ in aquaculture?
Aquaponics is a mutually beneficial system. It is a great way of farming fish and growing plants organically – hence its increasing popularity in SA.
South Africa’s fledgling tilapia industry has now reached a stage where it needs to be able to speak to funding agencies and the government with one voice.

All too often, even well-built, hi-tech grow-out systems are let down by inadequate filtration.
Techniques to produce all-male fingerlings are now an established part of tilapia culture and the use of mixed-sex groups is a backward step doomed to failure in any undertaking.
