Catfish Post Fingerlings
The Clarias catfish post fingerlings have given a great boost to aquaculture and impacted the livelihoods of many catfish farmers. The Clarias spp. can adapt to a wide variety of environments and is very tolerant of extreme water conditions.
- You will recognize the Clarias gariepinus by their cylindrical body with scaleless skin, small eyes, elongated spineless dorsal fin, and flattened bony head.
- The adult males are easily recognized by their distinct sexual papilla just behind the anus.
- They appear greyish black in color with a creamy-white underside.
- The Clarias spp. (African Catfish) are cannibals, hence, farmers need to properly sort them into different sizes and put them in the appropriate ponds.
Handling catfish fingerlings
- Handling live African catfish is easy because, as long as the skin remains wet, they can stay alive for many days out of water.
- Depending on fish size and market demand, the fish may be steaked; filleted; or sold headed, gutted, and skinned.
- Male African catfish exhibit the best dressing and fillet percentage.
- Compared to other species, C. gariepinus is low in lipid and consequentially has no intense flavor (smell and taste).
- Smoked African catfish are also in high demand be because they can be stored for longer periods without power while retaining nutritional quality.
- These fish are remarkably resilient.
