Ministry of Oceans and Fisheries needs to be careful about rising water temperature after the rainy season

The Ministry of Oceans and Fisheries notified fish farmers to pay attention to the rapid rise in water temperature after the rainy season as it is expected that the southern coast will gradually escape from the rainy season influence starting this week.

On July 11, the National Institute of Fisheries Science announced a high-temperature preliminary warning for 21 sea areas in the western and southern seas and the coast of Jeju, and the Ministry of Oceans and Fisheries issued a crisis warning caution level accordingly. This week, as the rainy season front moves north, the southern coast is expected to leave the area affected by the rainy season and a full-fledged rise in water temperature is expected. Particular caution is needed as damage to aquaculture organisms may occur due to a rapid rise in water temperature, especially in the coastal and inner bays.

If a rapid rise in water temperature occurs in a sea area where heavy rain has occurred, it can cause complex stress to aquaculture organisms. Therefore, before high temperatures occur, fish farmers must manage the health of aquaculture organisms by supplying feed containing nutrients and prepare response equipment such as liquid oxygen feeders.

The Ministry of Oceans and Fisheries is supplying response equipment to fish farms in advance and checking preparedness through on-site inspections, and the National Institute of Fisheries Science is expanding its real-time water temperature observation network to provide real-time water temperature information to fishing sites.

Minister of Oceans and Fisheries Kang Do-hyeong said, “As high temperature warnings are expected to be announced in mid-July, we hope that local governments will do their best to prepare in advance.” He added, “We hope that fishermen will take measures such as controlling stocking density and increasing oxygen supply. “The Ministry of Oceans and Fisheries will also continue on-site inspections to ensure that there are no on-site difficulties.”
