Octopus, raised for over 200 days from hatching in South Korea

Published 2024년 9월 2일

Tridge summary

The National Institute of Fisheries Science in South Korea has made history by successfully rearing octopuses for over 200 days, a feat only achieved twice globally previously. This advancement, which extends the previous record by nearly sevenfold, is part of ongoing efforts to establish artificial seed production technology for octopuses, a notoriously challenging process. Since 2018, the institute has consistently extended the rearing period, with the current record being 123 days in 2023. The institute's findings will be shared with the Aquaculture Research Council to advance octopus aquaculture technology, potentially improving the income of fishermen by allowing for the farming of octopuses from larvae to adults.

The National Institute of Fisheries Science announced on August 23 that it had recently succeeded in hatching and raising octopuses for over 200 days to grow them into a form similar to that of juvenile octopuses. The National Institute of Fisheries Science explained that the difficulty of raising octopuses through artificial seed production is very high, as only two cases have been reported worldwide. In 1980, one octopus was raised in Japan for 1 year and 2 months, and in 1986, one octopus was raised in the United States for 3 years and 2 months. There have been various research attempts at domestic research institutes, but no successful cases have been reported yet. The East Sea Fisheries Research Institute of the National Institute of Fisheries Science has been conducting basic research on initial food procurement and raising conditions to develop artificial seed production technology for octopuses since 2018, and has been developing raising technology every year.
