Farming remarks
Ictalurus punctatus is a nocturnal catfish species native to North America (St. Lawrence-Great Lakes, Hudson Bay, and Missouri-Mississippi rivers basins) and highly invasive in most of the USA, in some European countries, and Japan. In the US, it is dominating the aquaculture industry; worldwide, its production is highest in China, and it is also cultured in Cuba, Mexico, Russia, and Bulgaria. In aquaculture, it is often hybridised with the related species Ictalurus furcatus, and it can be co-cultured with this and with other species such as Polyodon spathula, Oreochromis niloticus, Pimephales promelas, and Lepomis microlophus. Escapees can be a threat to local populations of FISHES. There is a common high-standard slaughter method in place, and it is cultured with appropriate substrate and depth. However, further information is needed on stress during husbandry procedures and on the proportion of malformations in farms. There are several reports of natural spawning in farming conditions, and there is some potential to improve home range, migration needs, and aggregation needs and to reduce aggression levels.

Series 8 of our Fish Talk podcast programme on the FishEthoBase just launched. Please find it here. In audio features of less than 3 minutes each, you are invited to learn about Milkfish (Chanos chanos), Channel catfish (Ictalurus punctatus), and Pond loach (Misgurnus anguillicaudatus) and which aspects of their natural needs may or may not be accommodated in captivity. If you would like to dive deeper into our assessments of these species, you will find their profiles in our FishEthoBase.
2022-08-17: New species profile: Ictalurus punctatus
The latest addition to our Species tree is the nocturnal Ictalurus punctatus or Channel catfish. You are invited to explore the Overview and the Short profile for this species which dominates the aquaculture sector in the USA. Under ideal conditions, depth and reproduction needs are covered, and a slaughter protocol is in place. On the other hand, migration and substrate needs as well as a tendency towards solitary lifestyle, aggression, and stress prevent reaching good welfare in captivity.
