Blotched catfish

Introduction: The blotched catfish (Clarias stappersii) is a species of freshwater catfish found in various water bodies across Africa, including parts of Namibia. It belongs to the family Clariidae and is known for its adaptability to different aquatic habitats.

Distribution: The blotched catfish is widely distributed throughout Africa, including countries such as Namibia, Angola, Zambia, Democratic Republic of Congo, and others. In Namibia, it can be found in rivers, lakes, and swamps, particularly in regions with slow-moving or stagnant waters.

Diet: The blotched catfish is a highly opportunistic feeder and is known to consume a wide variety of food items. Its diet includes small fish, aquatic invertebrates, insects, crustaceans, and organic detritus. It is an essential part of the aquatic food chain, helping to control populations of smaller organisms.

Colouration: The blotched catfish has a typical catfish appearance with a cylindrical body covered in silvery scales. It has a flattened head and a wide mouth with numerous small, sharp teeth. The fish's colouration may vary slightly depending on the specific environment, but it generally exhibits a silvery or greyish hue.

Breeding: Breeding behaviour of the blotched catfish is not well-documented. Like other catfish species, they likely engage in internal fertilization, with males using specialized structures to transfer sperm to females. Females may then lay adhesive eggs in submerged vegetation or suitable crevices.

Size: The blotched catfish can vary in size depending on environmental conditions and age. Juvenile specimens can be relatively small, but adult individuals can reach lengths of up to 60 centimetres or more.
