海鲤,学名尖鳍鲤,是鲤属鱼类中长期生活在我国南海少数河口咸淡水水域的种类。为了丰富咸淡水养殖种类,有关科研人员在咸淡水及淡水池塘中进行驯化养殖及选育,先后突破海鲤的全人工繁殖及成鱼的饲养技术关。 1.食性在自然条件下,体长2.5～10厘米的个体主食轮虫、枝角类、桡足类、寡毛类、端足类及多毛类等;在人工饲养条件下,可用冰冻沙蚕等投喂。饲料中粗蛋白含量以35%以上为好。体长10厘米以下的个体要求饵料新鲜、质细、蛋白含量高。在性成熟前,水温10℃以上时海鲤保持摄食活动,尤以秋季的摄食强度较
Sea carp, scientific name fin carp, carp genus is long-term living in the South China Sea a few estuarine brackish freshwater waters. In order to enrich the species of brackish and freshwater aquaculture, relevant researchers conducted domestication breeding and breeding in brackish and freshwater ponds and successively broke through the whole artificial breeding of sea carp and the feeding techniques of adult fish. 1. Feeding In natural conditions, the body length of 2.5 to 10 cm of the individual staple food rotifers, cladocerans, copepods, oligochaetes, amphipods and polychaetes, etc .; in artificial feeding conditions, available frozen Nereis And so fed. Feed protein content of more than 35% as well. Body length of 10 cm below the individual requirements of fresh food, fine, high protein content. Prior to sexual maturity, the sea carp maintained its feeding activities when the water temperature was above 10 ℃, especially when the feeding intensity in autumn was lower than that in autumn
