Tridge summary

The National Institute of Fisheries Science in South Korea has released 200,000 young sea breams into the waters around Geojin Port and Ayajin Port in Gangwon-do, and Nam-ae Port in Yangyang-gun, in an effort to restore the rapidly depleting sea bream resources. This initiative is part of a larger plan by the East Sea Fisheries Research Institute to collect and hatch eggs stuck to nets during the spawning season. The institute has also successfully hatched and released sea cucumber fry using outdoor incubators, with plans to release approximately 4.6 million sea cucumber fry over the past four years. The institute is collaborating with local fishermen, governments, and organizations to monitor the effectiveness of these release projects.

Sea breams come to shallow coastal waters every November to December and lay eggs on seaweed, and the eggs hatch around January to February of the following year. However, domestic sea bream catches have decreased by nearly 95% from 7,462 tons in 2016 to 431 tons this year, raising concerns about the depletion of resources. Accordingly, the East Sea Fisheries Research Institute of the National Institute of Fisheries Science formed a ‘Sea bream Resource Recovery Task Force (TF)’ with fishermen, local governments, and related organizations at the end of last year and promoted a plan to collect eggs that are stuck to nets during the spawning season and hatch and release them. The East Sea Fisheries Research ...
