Kindai University in Japan achieves closed-cycle eel breeding

Published 2024년 3월 19일

Tridge summary

Japan's Kindai University Fisheries Research Institute has successfully achieved closed-cycle breeding of Japanese eels, a process first accomplished by the National Fisheries Research and Education Organization in 2010. The university aims to improve and develop original methods for this type of eel breeding, focusing on enhancing feed and producing glass eels for practical use in aquaculture. However, the process is currently labor- and equipment-intensive, necessitating further innovation for scalability and profitability. This development in closed-cycle aquaculture is a step towards reducing risks in traditional aquaculture and decreasing dependence on wild-caught elvers.

The Fisheries Research Institute at Kindai University in Higashiosaka, Japan, announced it succeeded in achieving closed-cycle breeding with Japanese eels by raising parent fish from artificial seedlings.This feat was first accomplished in 2010 by Japan’s Fisheries Research Agency (FRA), which has since been renamed as the National Fisheries Research and Education Organization, but the university’s replication of the achievement marks a major step forward in Japanese aquaculture research – especially coming from scientists at a university level.Kindai has previously garnered acclaim for its work on closed-cycle bluefin tuna breeding and is engaged in a wide range of fish breeding and aquaculture research.While the university’s most recent eel-breeding work used the methods developed by the FRA, it plans to conduct further research to develop original methods of completing closed-cycle eel breeding. Specifically, the researchers plan to work on improving the feed they use and aim ...
