黄鳝无土流水饲养法与常规的静水有土饲养法相比,具有生长快、成本低、产量高、起捕操作方便等优点,有条件的地方不妨一试。技术要点介绍如下: 一、建池选择有常年流水的地方建池,如水位差较大的河水、水库水、电厂发电后排出的冷却水,大工厂排放的机器冷却水等,如有温泉水的地方则更好,可以通过调节水温使黄鳝一直在适温条件下生长。池最好建在室内,用水泥砖砌,每只池大2～3平方米,池壁高40厘米左右,并在池的相对位置设直径3～4厘米大的进水孔一个和排水孔二个,进水孔与池底等高,排水孔一个与池底等高,一个高出池底4—5厘米,孔口都装金属网罩防逃。若干池形成一排,将几排池排列在一起,排与排之间既可以是进水渠,也可以是出水
Eel soilless water feeding method and the conventional hydrostatic soil feeding method compared with fast growth, low cost, high yield, easy operation and so on, the conditions may wish to try. Technical points are as follows: First, the pool choose to have perennial flow of water to build the pool, such as water level difference between the larger water, reservoir water, power plants after the discharge of cooling water, large factory discharge of machine cooling water, etc., if hot spring water The place is better, you can adjust the water temperature so that the eel has been growing under suitable temperature conditions. The pool is best built indoors, with cement brick, each pool 2 to 3 square meters, the pool wall height of about 40 cm, and the relative position of the pool to set a diameter of 3 to 4 cm large water hole and a drainage hole Two, the inlet hole and the bottom of the contour, a drainage hole and the bottom contour, a 4-5 cm above the bottom of the pool, the holes are fitted metal mesh hood to prevent. A number of pools form a row, the rows of pools arranged together, row and row can be between the intake channel can also be water
