近年来,福建省莆田市后海垦区网箱养殖一直使用冰鲜杂鱼,过量投喂,致使水质严重恶化,达到富营养化状态,已造成养殖海域的严重污染,致使养殖鱼类品质下降,养殖病害时有发生,给养殖户造成重大的经济损失,因此,改造传统的网箱养殖模式、整治养殖环境是十分必要和迫切的。后海垦区通过对500口网箱全程推广使用配合饲料,经过17个月的实施,水质环境得到明显改善,养殖病害也较少发生,取得了较好成效。
In recent years, cage farming in the Houhai Reclamation Area of Putian City, Fujian Province, has been using chilled trash fish for overfeeding, resulting in a serious deterioration of water quality and eutrophication, which has resulted in serious pollution of aquaculture waters, resulting in a decline in the quality of farmed fish and breeding Diseases have occurred from time to time, causing serious economic losses to farmers. Therefore, it is very necessary and urgent to transform the traditional cage culture model and rehabilitate aquaculture environment. After the reclamation of 500 cages throughout the promotion of the use of feed, after 17 months of implementation, water quality and environment have been significantly improved, less serious breeding diseases, and achieved good results.
