一、为什么培育鱼苗鱼种前要先做好鱼池的清理消毒工作,怎么做?答:刚孵化出来的鱼苗体如针芒,既小又嫩,活动能力很弱,对蝌蚪、水生昆虫、野杂小鱼等敌害无抵抗及逃避能力,抗病能力也很低;稍大些的鱼种,对外界的不良环境和敌害的抵抗力也较弱,因此,要保证较高的成活率,必须对培育饲养鱼苗的鱼池进行彻底的清理消毒。这在养鱼生产上叫做清塘。 First, why cultivate fish and fish species should be done before the cleaning and disinfection of fish ponds, how to do? A: The newly hatched fry body, such as pinnacles, both small and tender, activity is weak, tadpoles, aquatic insects, wild Miscellaneous fish and other enemy non-resistant and evasive ability, disease resistance is also very low; slightly larger species of fish, the adverse environment and predators outside the resistance is weak, therefore, to ensure a high survival rate, Fish ponds that breed and raise fry must be thoroughly cleaned and disinfected. This is called Qing Tong in the production of fish.
