A Review on Japanese Eel (Anguilla japonica) Aquaculture, With Special Emphasis on Nutrition

Abstract Aquaculture has experienced tremendous growth over the last few decades as global production has increased from 16 million tons in 1990 to 110 million tons in 2016. Meanwhile, the modern aquaculture industry is interested in the production of endangered species with great economic potential. Japanese eel (Anguilla japonica) is one of the most valuable species in East Asia with high market demand. But, unfortunately, this fish is critically endangered largely due to excessive harvesting at early life stages and deteriorating environmental conditions. Therefore, a sustainable aquaculture strategy is necessary to conserve and rehabilitate Japanese eel stocks while meeting market demand. In order to achieve this goal, efficient artificial breeding of Japanese eel and knowledge of nutritional requirements during every life stage is critical. The present review will cover recent research and technology in the areas of aquaculture and artificial breeding, and provide comprehensive information regarding the nutrition of Japanese eel. The information provided in this study is intended for researchers working on the aquaculture of Japanese eel by identifying the current knowledge and research gaps. This review is also helpful to feed manufacturers in producing practical diets for different life stages of Japanese eel.
