I. Parents At present, the more common operation is to select the "header" in the pond where the male and female are selected in different ponds, and some will also select some wild species of fish. Individual powerful companies will select the best through genetic testing. Variety conservation and breeding work. At the same time, parental cultivation and management are also more critical. It is necessary to strengthen nutrition while adopting an ecological cultivation method. This determines the amount and quality of carp eggs. Second, water quality We all know that the water quality requirements for hatchery use are relatively high. Without a good water source condition, the quality of fry can't be discussed. Third, medication At present, what we call salmonid virus disease is also related to this seedling application. Frequent use of antibiotics to prevent disease will severely damage the immune function of fry and cause white liver easily. If the probability of outbreak of virus disease during improper management is high, Greatly increased, and this medication situation we generally do not know the personnel, it is recommended that the seedling field to write a medication record at the same time install the camera for full monitoring, perhaps many people think that is not realistic, but I believe that will soon be realized, who dares to do first Whoever is the pioneer, the harvest will also be the biggest. Fourth, management For example, select the parents with better egg maturity, accurately grasp the amount of oxytocin, open the hatching of the later fry, do not use antibiotics to prevent disease, and the fry are often screened to eliminate the seedlings and sell seedlings.
