Description

Clarias Juveniles

The Clarias juveniles 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 clarias juveniles

• 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.
