The problem with aquaponics
Currently, too many systems cruelly compromise fish quality to favour plant production. But there’s a simple solution to this unacceptable state of affairs that will see both flourish.
Aquaculture jobs and training
Fish farming is an attractive occupation that appeals to many young people. What should they do to get started?
Aquaculture feed
The main operating cost of intensive aquaculture ventures is feed, and many ventures fail due to excessive spending on this input. Larger, warm water projects are now carefully scrutinising feed costs.
Controlling diseases in aquaculture systems
Producers can use a variety of methods to limit diseases in their commercial aquaculture systems.
Fish farming in Winter
When it comes to temperature levels, warm water fish farms and trout farming are at opposite ends of the spectrum. While tilapia hibernates in winter, trout prefer the cooler weather.
A fingerling’s happy home
Spacious tanks, consistency in water temperature and quality, and using both natural and live feed will ensure robust, healthy fish.
Fish breeding do’s & don’ts
There’s more to breeding than sticking fish in the water and hoping for the best. Start off with the right type of tank, get quality fish, and avoid inbreeding.
Tilapia on our shelves
Long considered the ‘aquaculture fish of the future’, tilapia products are now being imported in quantity from Zimbabwe, writes Stephen McVeigh.
Developing a pond farm
There is no reason that pond fish-farming could not be viable in parts of South Africa, as it is already successful elsewhere in Africa.
Fish fall foul of new laws
For many years, aquaculture in South Africa has had to play second fiddle to the various departments of nature conservation. Now this
has changed. Or has it?
Aquaculture: Are we making progress?
A brief overview of the current state of fish farming in South Africa.
Infrastructure for aquaculture
Adapting existing buildings and dams for aquaculture seems a neat, money-saving solution. Yet this usually leads to failure. Unless you know what you’re doing, build a dedicated setup – you won’t regret it.
