Crocodile meat meal for juvenile dusky kob in South Africa

Short or long-term supplementation using omega-3-rich oils is proposed for crocodile meat meal (CMM)-fed juvenile dusky kob (Argyrosomus japonicus). A preliminary study in South Africa investigated the effect of replacing fishmeal with raw or cooked crocodile meat meal on feed utilization, growth performance, blood parameters, and tissue nutrient composition in juvenile dusky kob (Argyrosomus japonicas). It concluded that crocodile meat has good characteristics as a fishmeal substitute. “Using crocodile meat as an alternative source of protein for carnivorous fish, such as the dusky kob, could be an ingenious strategy that adds value to the crocodile farming enterprise, while ensuring economically and environmentally sustainable dusky kob aquaculture,” Reginah M. Mdhluvu et al. said in the study published in Aquaculture Reports. As a fishmeal substitute, however, the study showed that CMM compromised growth of juvenile dusky kob. It likewise had an adverse impact on the level of ...
