Changwon City collects 45 tons of dead sardines...Last year's cause was ``lack of oxygen'' = South Korean report

After a large number of sardines died at Masan Port in Changwon City, South Gyeongsang Province, the city is awaiting analysis results after collecting all the carcasses.
On the 15th, Changwon City announced that it had recovered all 45 tons of dead sardines off the coast of Nuri Park in Masan.
On the same day, approximately 220 people including city employees and fisheries personnel were at the scene, including fishing boats and equipment.
40 vehicles were mobilized. On the 11th, Changwon City sent samples of dead sardines to the National Institute of Fisheries Science and is awaiting analysis results to determine the cause of the mass mortality.
Changwon City Mayor Hong Nam-pyo said, ``Regarding the mass death of sardines that occurred on the 11th, we have recovered all of the carcasses.''
We will also keep a close eye on the possibility of mass deaths and minimize the concerns of the public." Approximately 200 tons of sardines died off the coast of Masan last year.
At the time, the National Institute of Fisheries Science concluded that the cause of the sardine's death was suffocation due to lack of oxygen. In the same area, a lack of oxygen in the seawater caused a large number of sardines to grow.
This is because no infectious disease-causing bacteria or harmful substances that could cause death were detected. Normally, when fish die due to lack of oxygen, they exhibit the characteristic symptom of opening their mouths, but many dead bodies like this occur.
This was also one of the factors that led to the diagnosis of oxygen deficiency. In May, Changwon City took measures to prevent a recurrence of the mass death of sardines. In addition, the sunken sardine carcasses were resurfaced.
The plan is to continue deploying treatment teams in consideration of the possibility that the virus will surface.
