Farming remarks

Tachysurus dumerili
Li0  ❘  Po0  ❘  Ce0

Tachysurus dumerili is a demersal and nocturnal catfish species that lives in rivers of eastern China and western Korea. Culture of T. dumerili became popular in China due to its high market value and a rapid declining of the natural population, affected by overfishing, environmental pollution, and habitat fragmentation. Efforts have been put in researching nutritional parameters and genetics of T. dumerili. However, there is a reported lack of data on broodstock management, captive breeding, and larval rearing techniques. Additionally, there is a lack of English literature on T. dumerili's natural habitat and behaviour in the wild. T. dumerili is very aggressive while in captivity and has been reported to be stressed by handling, which are unfavourable welfare parameters for cultivated species. The most probable slaughter technique used for T. dumerili is ice slurry. Therefore, an alternative high-standard slaughter method needs to be researched for this species.
