补充资料:淡水养殖
淡水养殖
淡水养殖利用池塘、水库、湖泊、江河以及其他内陆水域饲养和繁殖水产经济动物的生产。养殖的对象主要为鱼类。中国淡水养殖鱼类主要包括青、草、维、鳍、鲤、螂、编、妨、非卿等经济性鱼类。中国淡水养殖面积和产量均居世界首位。淡水养殖有以下几种主要生产方式:①池塘养鱼。一般指在面积较小的封闭水体中的鱼类养殖。这种经常处于静水状态的小型水体,多由人工开挖或天然水潭改造而成,是中国历史上最早的一种养鱼方式。②湖泊、河道养鱼。指在中小型湖泊或河道的进出口建筑拦鱼设备养鱼。主要利用天然饵料,辅以人工施肥投饵。③水库养鱼。利用各种类型的水库养殖鱼类。在小型的农田灌溉水库,凡可以防逃、容易捕捞的,可采取池塘养鱼方式;一般较大的平原水库,常采取湖泊、河道方式经营;大型综合水库,主要繁殖保护鱼类资源,辅以少量的人工放养。在水库的库湾修建堤坝或拦网,将其与水库主体部分分开,在被拦的库湾中养鱼,可以有效地提高整个水库的渔业产量。④稻田养鱼。利用水稻田养鱼,既可增加鱼产量,又可消除稻田中的害虫、杂草,疏松土壤,肥沃稻田,增加水稻产量。⑤工厂化养鱼。运用机械的、电气的、化学的、自动化的现代化措施,在水质、水温、水流、溶氧、光照、投饵等方面进行人为控制,创造和保持最适宜于鱼类生长和发育的生态条件,使鱼类的繁育、苗种培育、商品鱼的养殖等各个环节都处在人工控制的水体环境中进行无季节性的连续生产工厂化养鱼主要有自流水式、循环流水式和温流水式⑧网箱养鱼用纤维网片、金属网片等材料缝制成长方体、圆柱体等具有一定形状的箱体,将其架设在较大水体中,使箱体内外水体可以自由交换。
