On a beach in Goseong-gun, Gangwon-do, an enormous amount of squid was pushed to the sandy beach and found dead.
7cm small squid that lives in the deep sea
There is also a group death on the beach in Sokcho in 2013
According to Goseong-gun on the 14th, residents discovered that a small school of squid was pushed to the white sand and died on the beach in Bongpo-ri, Toseong-myeon. At that time, squid was scattered about 500m from Bongpo Port to the vicinity of Cheongganjeong. Most of the squids were only 4~5cm in size. “I have lived in Bongpo-ri for more than 40 years, and this is the first time,” said one resident. “I have seen a herd of anchovies pushed to the beach, but I have never seen a squid pushed out.
On this day, the small squid pushed out of the coast of Goseong was identified as majestic squid. Squid lives in the deep sea at a depth of 200-600m, and it is only 7cm in size when it becomes an adult. Experts believe that the squid was pushed out of the beach because of the upset phenomenon of seawater. The rise-up phenomenon refers to a phenomenon in which low-level water rises to the surface to fill in voids created when seawater from the coast is pushed toward the open sea by wind.
An official of the National Institute of Fisheries Science explained, “It is highly likely that the squid, which lives in the deeper waters than the cuttlefish, died without enduring the rapid changes in water temperature and air pressure caused by the uprising phenomenon and was pushed to the shore.”
This is not the first time that large amounts of squid have been pushed out of the east coast of Gangwon-do. A similar thing happened at Sokcho Beach in December 2013. At that time, there was a scene where residents and tourists flocked to the beach to pick up squid.
At that time, the National Fisheries Research and Development Institute conducted a close examination to find out the cause of the death of a squid found in Sokcho Beach. As a result, radioactive cesium or iodine was not detected in the cuttlefish, so the cause of swarm death was not related to radioactive contamination. On the other hand, the cuttlefish is a marine luminescent species with black luminescent cells in its arms, and has a lifespan of about 1 year.
