Furthermore, in the step (4), oxygen is supplied through the dissolved oxygen cone, a ceramic aeration disc is additionally arranged to serve as standby emergency oxygen supply, and oxygen is increased when power failure or system failure occurs.
Further, a microfiltration machine, a foam separator, a biological oxidation system, a water-soluble aerator, a gas/water mixing dissolver, an ultraviolet disinfection system and a hatching tank are also required in the step (4).
Further, detoxification and water fertilization before seedling release in the step (6): 2 days before putting the seedlings, adding water into the cultivation pool to a depth of 50-80cm, adding water into the antidote, and splashing antidotal agent into the cultivation pool; 1 day before putting seedlings, adding water into the cultivation pool to the depth of 80-100cm, activating the composite lactobacillus biological ferment with the water in the cultivation pool for 4-6h, splashing the composite lactobacillus biological ferment onto the water surface of the cultivation pool, and diluting the water ecological restoration agent with the water in the cultivation pool and splashing the diluted water onto the water surface of the cultivation pool.
Further, feeding the whitebait fries in the breeding pool in the step (7), selecting special puffed compound feed for breeding the whitebait fries, feeding for 4-6 times every day, adjusting according to the weight of the whitebait fries, wherein the feeding amount of each time accounts for 6-8% of the total weight.
Further, in the step (7), the hatched fries are subjected to specification selection and are placed into different breeding ponds in a classified mode.
The method is suitable for the industrial silver salmon fry high-efficiency cultivation method for cultivating large-area silver salmon fries.
The application has the advantages that:
the method is simple to operate, and the problem that the industrial silver salmon fry is high in survival rate and yield due to the fact that large-scale industrial production cultivation is achieved is solved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
