(4) The prawn nauplii stage is fed with no bait, 6 times daily, the early stage larvae have poor vigor, a small amount of water is added from a water inlet to improve the water quality, the middle and later stages are aggravated along with the pollution of pond water, water is changed through a sewage outlet, the water changing amount is gradually increased, and the feed is supplemented until the larva period begins to supplement with artemia to ensure sufficient nutrition;
(5) Culturing shrimp larvae until the body length is 1cm, stopping heating by a boiler, randomly selecting 50 shrimp larvae per family, leaving the shrimp larvae in a culture barrel, covering a layer of escape preventing net above the culture barrel, avoiding bouncing out of the shrimp larvae, feeding for 4 times per day, and changing water amount to 60% per day;
(6) And (3) keeping 50 shrimp fries randomly selected and reserved in each family in a culture barrel for continuous culture until 150 days old, counting the culture survival rate of each family, weighing the total weight of the shrimps in each culture barrel, taking the body mass as a main selection target property weight of 60%, and the survival rate as an auxiliary selection property weight of 40%, comprehensively selecting the families entering the next breeding step, and finally retaining 18 families with obvious advantages after selection.
2. The seedling cultivation method of the aquatic animals under the common environments of different families is characterized by comprising the following steps:
(1) Assembling, cleaning and sterilizing various devices of the system: the method comprises the steps of soaking or splashing a blower, a boiler, a water tank, culture barrels, a bolting silk net, PVC vertical pipelines, an inflatable hose, inflatable stones, a heat supply line pipe, PVC parallel pipelines and a circular ring piece with potassium permanganate solution, cleaning with clean water for later use, placing two rows of culture barrels in a single water tank, placing 51 culture barrels in each row, connecting the culture barrels with the PVC parallel pipelines, and mounting 500-mesh bolting silk net at the bottom of the culture barrels;
(2) And (3) water storage: seawater enters a water tank through a water inlet after passing through a dark sedimentation tank, a foam separator and a sand filter, water is added until the water surface is 0.8m, then slaked lime, EDTA, a microbial preparation and shrimp slices are added, then a blower is turned on to charge air so that the water in a PVC vertical pipeline is continuously and slowly added into a cultivation barrel, then a heat boiler is burned, the pH value is kept between 8.0 and 8.6, and the water temperature is adjusted between 29 and 31 ℃;
(3) Marking the outer wall of a water tank corresponding to each cultivation barrel by using a Mark pen, starting to number X01-X51 from the first cultivation barrel in the front row, starting to number Y01-Y51 from the first cultivation barrel in the rear row, putting fertilized eggs of prawns into corresponding cultivation barrels one by one, putting the same fertilized egg family into each cultivation barrel, controlling the putting quantity of each cultivation barrel to be equal to or less than 500g fertilized eggs, and freeing the two corresponding cultivation barrels of X51 and Y51 for standby, so that 100 different families can be cultivated simultaneously, wherein 1-50 different families are corresponding to barrels with numbers X01-X50, and 51-100 different families are corresponding to barrels with numbers Y01-Y50;
(4) The prawn nauplii stage is fed with no bait, 6 times daily, the early stage larvae have poor vigor, a small amount of water is added from a water inlet to improve the water quality, the middle and later stages are aggravated along with the pollution of pond water, water is changed through a sewage outlet, the water changing amount is gradually increased, and the feed is supplemented until the larva period begins to supplement with artemia to ensure sufficient nutrition;
(5) Culturing shrimp larvae until the body length is 1cm, stopping heating by a boiler, randomly selecting 50 shrimp larvae per family, leaving the shrimp larvae in a culture barrel, covering a layer of escape preventing net above the culture barrel, avoiding bouncing out of the shrimp larvae, feeding for 4 times per day, and changing water amount to 60% per day;
(6) And (3) keeping 50 shrimp fries randomly selected and reserved in each family in a culture barrel, continuously culturing for 150 days, counting the culture survival rate of each family, weighing the total weight of the shrimps in each culture barrel, taking the body mass as a main selection target property weight of 60%, and comprehensively selecting the family entering the next breeding by taking the survival rate as an auxiliary selection property weight of 40%.
3. The method for cultivating seedlings in a common environment of different families of aquatic animals according to claim 2, wherein in the step (3): when the excrement is cleaned in the culture barrel, the excrement can be gradually transferred to the empty culture barrel of the partition wall, namely, firstly, the corresponding families in the X50 culture barrel are transferred to the empty culture barrel of X51, then the empty culture barrel of X50 is cleaned, then the corresponding families of X49 are transferred to X50, and the families in X01 are cleaned and transferred one by one according to the sequence until the families in X02 are transferred, and meanwhile, in the transferring process, the original bolting silk net in the culture barrel is replaced by the sterilized and insolated bolting silk net, so that the bolting silk net is prevented from being not replaced and larvae are hung on the bolting silk net, and the next family is prevented from being mixed; the method for cleaning the excrement in the culture barrel of the Y01-Y51 can be used for cleaning the excrement in the culture barrel of the X01-X50.
