鳜鱼是野生淡水鱼类名贵品种之一,具有肉嫩、刺少、味美等优点而深受群众喜食。但从当前产销情况来看,光靠野生鳜鱼远远不能满足消费者的需要,必须要进行人工繁殖以扩大其来源。为此目的,我们于1986—1987年在广东省南海县和湖北省嘉鱼县进行了人工繁殖试验,已取得了初步成效。现将试验情况简介如下。 一、试验情况 (一)亲鳜培育 亲鳜培育在封闭式网箱中进行,网箱规格为4×4×2米,网盖离水面20—30厘米,以防缺氧浮头,亲鳜重1.0—1.5公斤。每平方米放养3—5尾。投喂的饵料鱼是以餐条鱼为主的各种野杂鱼。每日投喂一次,
Anchovy is one of the rare species of wild freshwater fish, with tender, prickly, delicious and so popular by the masses. However, judging from the current production and marketing situation, it is far from satisfying the consumers’ needs to depend on wild catfish. It is necessary to carry out artificial breeding to expand its sources. For this purpose, we conducted artificial breeding experiments in Nanhai County, Guangdong Province and Jiayu County, Hubei Province from 1986 to 1987 and achieved initial success. Now the test situation is as follows. First, the test conditions (a) nurturing parenting Nursing training in closed cages, cage size of 4 × 4 × 2 meters, cover 20-30 cm from the water to prevent hypoxic floating head, pro-Qin weight 1.0-1.5 kg. 3-5 tailings per square meter. Feeding bait fish is based on a variety of wild fish. Once a day feeding,
