Distribution sources
Identification
Scaleless skin, a broad head, eight barbels and a small adipose fin characterise Ameiurus melas. The pectoral and dorsal fins bear spines; do not grasp it blindly.
Habitat
Ponds, lakes, backwaters and quiet river sections, including turbid water. Its ecological tolerance does not authorise moving it to another habitat.
Diet
Omnivorous: bottom organisms, larvae, worms, eggs and small fish, as well as plant material.
Behaviour
A bottom fish often active at night. This activity is neither permission for night fishing nor a reason to keep an individual alive for later.
The metropolitan order of 14 February 2018 consulted, in the consolidation displayed for 10 October 2026, subjects live specimens to the restrictions in Article 3, including keeping, transport, use and introduction into the natural environment, subject to regulated authorisations. The practical procedure after capture still requires local confirmation.
Indicative biological size
Generally 15–20 cm according to DORIS; not a legal size limit.
Fishing context and precautions
Ameiurus melas — Prevention after an incidental capture: do not release this fish, transport it alive or use it as bait. Before fishing, establish the procedure and destination specified by the manager or competent authorities. This identification sheet describes neither targeted fishing nor a personal eradication operation.
A distinctive feature
The fry can remain grouped in a compact ball for several weeks.
