在这一次超级寒潮中,广东地区渔业生产遭受严重损失,近海海水网箱养殖也受到严重打击。对于这一现象,中山大学教授、海水网箱养殖专家黎祖福无奈表示,目前针对海水网箱养殖并没有直接有效的抗寒办法。“海水网箱养殖前期要考虑几个因素,包括海域的选择和网箱的深度。”黎祖福说,海水的水深差每5米就存在温差2~3℃,看上去这2℃不起眼,但事实上,一些不耐寒的品种,从健康状态到冻伤,就差这2~3度。
In this super cold, fishery production in Guangdong suffered serious losses, and offshore seawater cage culture was also severely hit. For this phenomenon, Sun Yat-sen University professor, sea cage culture expert Li Zu-fu reluctantly said that at present there is no direct and effective cold-resistant cage farming methods for seawater cage culture. “There are several factors to consider in the early stage of seawater cage farming, including the choice of sea area and the depth of the cage.” "Zizhu Fu said that there is a temperature difference of 2 ~ 3 ℃ every 5 meters of seawater, which seems like 2 ℃ , But in fact, some not cold-resistant varieties, from the state of health to frostbite, the difference is 2 to 3 degrees.
