吴郭鱼,又称台湾改良罗非鱼,是经过改良的一种罗非鱼新品种。与普通罗非鱼比较,该鱼有以下几方面的优点: 一、生长速度快 养成500克以上的商品鱼,普通罗非鱼要10个月以上,而吴郭鱼只要6个月。 二、适应性强 吴郭鱼在4℃以上水温条件下均可养殖。我国长江以南地区均可越冬。最适水温25～35℃,放氧2个月可达150克。吴郭鱼耐低氧能力很强。即使离水后,只要鳃部保持潮湿,还可活3～5小时,比一般鲤科鱼类的耐低氧能力都强。因此,吴郭鱼在密养情况下,在水质较肥的池塘环境中,也能适应生存,并
Tilapia, also known as Taiwan’s improved tilapia, is a modified tilapia new breed. Compared with ordinary tilapia, the fish has the following advantages: First, the growth rate to develop more than 500 grams of commercial fish, ordinary tilapia to more than 10 months, while the tilapia just 6 months. Second, the adaptability of tilapia in 4 ℃ above water conditions can be breeding. China’s winter region south of the Yangtze River. Optimum temperature 25 ~ 35 ℃, oxygen up to 150 grams 2 months. Tilapia Hypoxia tolerance is very strong. Even after leaving the water, as long as the gills remain moist, but also live 3 to 5 hours, than the general carp resistance to hypoxia are strong. Therefore, the tilapia in the close-packed case, in the pond water environment more fat, but also to adapt to the survival, and
