Catfish

To the family of catfish (Siluriformes) belong 1727 different species. They are called catfish due to their distinctive feelers. Catfish can weight over 100 kilograms, however, most species are significantly smaller. Catfish possess the organ of Weber which is a small set of bones that are connected to the swimbladder and transmit vibrations.

Catfish are commercially very important and are either farmed or wild-caught. Well-known species are pangasius and the African sharp tooth catfish.

African sharptooth catfish

This catfish can be found in lakes, rivers, and swamps in Africa and the Middle East. It has an elongated, dark coloured body that can reach up to 1.70 m and weigh as much as 60 kg. The African catfish is not a very demanding species in terms of water quality. This makes it is a very popular fish to farm; the fish has already been used for aquaculture practices since the 80s.

Explanation assessment

Catfish gets a good rating on the VISwijzer because the aquaculture does not lead to negative effects on the direct environment and the fish does not need a large amount of wild fish to grow. A unique feature is that a large part of the Dutch catfish is killed humanely.

The African sharptooth catfish (Clarias gariepinus) is a fish species that has been farmed for 30 years in the Netherlands. In nature they can reach a length of 1,50 meters and a weight of 60 kg, however in the Netherlands they get a weight of a few kilo’s.

Catfish have a special organ which allows them to get oxygen from the air, a lack of oxygen is therefore less of a problem. They can generally live with well with other specimens of the species, even stronger, the more space a catfish has available, the more territorial it gets.
