Aquaponics: how to get plumper, healthier fish
If you want to grow plants and decent-sized fish, the first step is to get rid of those plastic circular bins.
Cage culture for SA: small scale, big benefits
There are massive dams and reservoirs in South Africa that are ideal for cage culture, yet are not used for this purpose. What a waste of this marvellous resource!
Reared in brackish water, and worth its salt!
Brackish water can be put to good use in the cultivation of tilapia. Despite being primarily a freshwater species, tilapia are salt-tolerant and actually thrive in saline conditions.
A single ideal aquaculture system? Forget it!
On paper, many aquaculture systems look appealing, but are they suited to South Africa’s challenging conditions?
Aquaponics: a teenager’s passion grows into a business
A Pretoria-based teenager is running a successful aquaponics farm, and doing so with expertise and foresight.
Small aquaculture systems: the simpler, the better!
Because of their scale, these systems have very limited yields. Choosing a complex, small system will not increase yield; it will only increase cost!
Bass: an easy-to-breed alternative in aquaculture
With its wide temperature tolerance, the humble bass may be a good option for commercial production.
The World Aquaculture Society Conference 2017
The World Aquaculture Society held its first-ever conference in Africa, in Cape Town from 27 June to 30 June, along with the biannual conference of the Aquaculture Association of Southern Africa.
How the state is ‘capturing’ aquaculture
Legislative control of the aquaculture industry in South Africa is so restrictive that it impedes any development.
Lowveld fish farming: an indisputable investment
Cool, high-altitude regions with soil unsuitable for crop production can be turned into lucrative fish farms.
Three decades later: progress or regress?
In South Africa, it’s easy to become depressed, but the progress made in other African countries shows that, with the right attitude, fish farming can flourish.
Cold-tolerant tilapia can weather winter’s chill
Taking tilapia cold tolerance ranges into account shows how just a few degrees can make for a worry-free season.
Why you don’t need an intricate filtration system
Filtration systems with sophisticated designs rarely work efficiently. Instead, growers should focus on higher volumes.
South Africa’s potential pond farming bonanza
Pond aquaculture systems may be the answer to producing bulk quantities of tilapia simply and affordably.
Small-scale fish farming
With government assistance, many rural small-scale fish farmers could turn their operations into viable enterprises.
Selling your fish: which customers are best for you?
Before embarking on a tilapia farming business, carefully consider who your buyers will be – your success will depend on it!
Diseases in the fish farming sector
Keeping rearing conditions clean and sourcing fingerlings from reputable hatcheries will help contain outbreaks.
SA aquaculture success lies with government
The success and viability of the industry is largely government’s responsibility, because only it makes and implements legislation.
Managing water temperature in winter
The high altitude in parts of Southern Africa can play havoc with temperature control on the sub-continent’s tilapia farms. There are, however, measures that can be implemented to counter this.
