Introduction to African catfish

African catfish (Clarias gariepinus) is appreciated for its meat quality and taste in many countries in Africa, Europa and Asia. It was introduced in The Netherlands in the early 80’s of the last century as a promising candidate for Dutch aquaculture. From 1985 catfish was cultured commercially in The Netherlands.

Right from the start we were involved in the production of catfish fingerlings for the growing aquaculture sector in The Netherlands from our hatchery in Someren, The Netherlands. Our broodstock originated from wild strains from different regions in Africa and Israel. By selection on specific traits, like stress resistance, improved growth capacity and high filet percentage, using data obtained from customers, it was possible to develop the “Dutch Strain”.

Our fish performs very well in RAS grow out farms as well as semi-flow through and pond systems. Its docile character allows the fish to quickly regain normal behavior after a stressor like grading.

Performance of Dutch Strain African catfish

Under optimal circumstances (RAS facility, using extruded diet 44% protein 12% fat) our fish show the following performance:

Growth capacity In 6 months from newly hatched fry to 1,5 kgs
Filet percentage 45%
Feed Conversion Ratio (FCR) 0,85

Hybrid catfish

Next to the Dutch Strain African catfish, Aquaculture ID also supplies Hybrid catfish (Heteroclarias sp.). This is a hybrid between the Dutch Strain African catfish (Clarias gariepinus) and the Vundu (Heterobranchus longifilis). The hybrid catfish has the same growth performance as the Dutch Strain African catfish, but has an almost white fish fillet and a higher fillet percentage. The higher fillet percentage is caused by the absence of ovaries in the female fish; these hybrid fish do not produce eggs or sperm.

From our hatchery in The Netherlands Aquaculture ID supplies fry and fingerlings as well as ready-to-spawn broodstock to farmers worldwide.
