二、养鳟场的条件和设施(一)选点1.水质和水量:要有水量充足清冽的冷水。水中溶氧要充足,所以水量要充沛,最好是流水,也可以造成自然落差增氧或用机械增氧。水源以涌泉水、深层地下水(自流井)为好。水质要好,无污染。适宜水温为4—20℃,最好是10—18℃。2.饲料来源:虹鳟鱼是肉食性鱼类,在人工配合饲料中要有一定比例的动物性饲料,所以,建场要考虑当地动物性饲料的来源、品种和数量能不能满足养鳟的需要。3.地形:要有一定的倾斜度
Second, raise the conditions and facilities of trout (a) the election point 1 water quality and quantity of water: to have sufficient quantity of clear water of cold water. Dissolved oxygen in the water should be sufficient, so the amount of water should be abundant, the best water, can also lead to natural oxygen or mechanical oxygen gap. Water springs to springs, deep groundwater (artesian wells) as well. Water quality is good, no pollution. Suitable water temperature is 4-20 ° C, preferably 10-18 ° C. 2. Source of feed: rainbow trout is carnivorous fish, artificial diet should have a certain proportion of animal feed, so the establishment of the site to consider the source of animal feed, breeds and quantity can not meet the needs of the trout . 3. Terrain: have a certain degree of inclination
