工厂化养鱼又称工业化养鱼,是近年来世界上蓬勃发展起来的一门养鱼新技术。与传统的天然水面养鱼或池塘养鱼不同,它是让鱼类在人工建造的鱼池中(一般为水泥、砖、石结构),通过加高水温、机械增氧、自动控制调节水的各种条件等,并经过人工投喂颗粒饵料的办法,使鱼的放养密度加大,生长加快。用这种方法可以把池塘养鱼的周期由二、三年缩短到三、四个月。以三个月为一个养殖周期计算,一年可以收获鲜鱼三到四次,亩产鲜鱼可达几万斤以上,甚至超过
Industrialized fish, also known as industrialized fish farming, is a new fish farming technology booming in the world in recent years. Different from the traditional natural water surface fish culture or pond fish culture, it is to make the fish in artificial fish ponds (usually cement, brick and stone structure), by adjusting the water temperature, mechanical aeration and automatic control Kinds of conditions, etc., and after artificial feeding particle bait approach, fish stocking density increased, growth accelerated. In this way, the cycle of pond fish farming can be shortened from two or three years to three or four months. Calculated in three months as a breeding cycle, fresh fish can be harvested three to four times a year, per mu of fresh fish up to tens of thousands of pounds, or even more
