The Clarias catfish has given a great boost to aquaculture and impacted the livelihoods of many catfish farmers. The Clarias spp can adapt to a wide variety of environment and is very tolerant of extreme water conditions.
The Clarias Spp (African Catfish) are cannibals. Hence, farmers need to properly sort them into different sizes and put them in the appropriate ponds.
Precautions when stocking ponds with post juveniles
- Reduce stress from point of transportation to point of introduction into the pond.
- Avoid exposure to heat by covering transport containers
- Avoid shaking containers unnecessarily while transporting.
