Development of Oyster Larvae Feed with Sea Lettuce

Published 2025년 12월 5일

Tridge summary

A new prospect for utilizing the problematic green algae, Undaria pinnatifida, as a raw material for abalone feed has emerged along the coast of Jeju. The National Institute of Fisheries Science (Director Choi Yong-seok, hereinafter referred to as the Institute) announced on the 2nd that it has recently developed a manufacturing technology (national patent) to use Undaria pinnatifida as a raw material for abalone feed. Undaria pinnatifida mainly occurs in large quantities along the coast of Jeju Island during the summer, causing problems such as deteriorating the natural landscape and generating bad odors, and it incurs a significant cost for collection and disposal every year. The amount of Undaria pinnatifida collected in the Jeju region from 2020 to 2024 is approximately 22,000 tons, and the annual disposal cost is around 200 million won.

The problem of green nori in Jeju's coastal waters is expected to be newly utilized as a raw material for abalone feed. The National Institute of Fisheries Science (Director Choi Yong-seok, hereinafter referred to as the Institute) announced on the 2nd that it has recently developed a manufacturing technology (national patent) to use green nori as a raw material for abalone feed. Green nori mainly occurs in large quantities along the coast of Jeju Island in the summer, causing problems such as degrading the natural landscape and causing bad odors, and it costs a lot of money to collect and dispose of it every year. The amount of green nori collected in the Jeju region from 2020 to 2024 is approximately 22,000 tons, and the annual disposal cost is about 200 million won. The Institute's Feed Research Center has been conducting research on the development of abalone feed using green nori since 2023, and as a result, it has been confirmed that it can completely replace the main raw ...
