Many experts have the theoretical knowledge, but fail to put themselves in the shoes of the rural, small-scale fish farmer.
Green water culture provides a highly nutritious ‘soup’ of feed for fish stock, promoting faster growth. It also cuts out the high cost of artificial feed.
Small-scale aquaculture will never succeed if producers are forced to finance heavy-security fencing for their ponds.
Nile tilapia has become the species of choice for global commercial aquaculture after years of selective breeding.
If you want to grow plants and decent-sized fish, the first step is to get rid of those plastic circular bins.
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!
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.
On paper, many aquaculture systems look appealing, but are they suited to South Africa’s challenging conditions?
A Pretoria-based teenager is running a successful aquaponics farm, and doing so with expertise and foresight.
Because of their scale, these systems have very limited yields. Choosing a complex, small system will not increase yield; it will only increase cost!
Fish species that are adapted for rivers generally perform better under aquaculture’s challenging conditions.
With its wide temperature tolerance, the humble bass may be a good option for commercial production.
