Attractants from tilapia skin, Oreochromis niloticus (Perciformes: Cichlidae), to reduce feed waste in aquaculture farms
Introduction: Aquaculture has emerged as an alternative to traditional fishing due to the collapse of fish populations from intensive off-shore fishing. However, many aquaculture farms could reduce feed waste by using chemical attractants to concentrate fish during feeding. Objective: To test a tilapia skin attractant. Methods: Attractants were tested with 16159 mature and immature tilapias in confined indoor freshwater and saltwater ponds, and in outdoor ponds. Results: With the attractant, the immature fish approached food faster than in the controls (p<0.05). Attractants extracted from waste skin reduce pollution, are not bio-accumulable in tissue and use reagents that do not affect meat quality because they are highly soluble in water. Conclusions: The use of skin attractants is recommended as chum and not as an additive for food under controlled environments, but more research is needed in open environments
