Weighing how many shrimps are 1 jin after 7 months, then obtaining the average weight of one prawn, weighing the total weight of the shrimps, and calculating the total tail number of the alive shrimps by dividing the total weight of the shrimps by the average weight of the shrimps:
survival (%) × (total mantissa of surviving shrimps/initial mantissa) × 100%.
Disease incidence (%) — area of onset/area of measure.
The survival rates and disease incidence rates for the different breeding test groups are shown in table 5.
TABLE 5
As can be seen from tables 1 and 2, regardless of the water quality change in the middle stage of cultivation or the water quality change in the later stage of cultivation, compared with the comparative example, the microbial water quality regulator of the embodiment of the invention can keep stable water quality after different probiotics are added in different cultivation stages, is beneficial to good intestinal micro-ecology of aquatic animals, and inhibits the propagation of pathogenic microorganisms in water. As can be seen from tables 3 and 4, after the probiotics in the water-rich period is added into the water body in the early stage of cultivation, the water quality is tender, the growth of the young prawns is fast, and in the early stage of cultivation, the transparency of the embodiments 1 to 3 is lower than the ratio, which indicates that after the microbial water quality regulator of the embodiments of the invention is added, the biomass in the water body is higher, more bait is eaten by aquatic animals, and the growth of the prawns is facilitated. In the later stage of cultivation, the transparency of the comparative example is obviously lower, and the chemical index is correspondingly higher, which shows that pathogenic bacteria and blue-green algae in the water body are bred, so that the health of aquatic animals is easily influenced. After the microbial water quality regulator in the embodiment 1-3 is used, the water body transparency in the later period of cultivation is higher. Therefore, the microbial water quality regulator provided by the embodiment of the invention can effectively solve the pollution problem of aquaculture. As can be seen from Table 5, the weight of the prawns using the microbial water quality regulator of the embodiments 1-3 of the invention is increased significantly, the feed conversion rate is high, and the yield of the prawns is relatively increased by more than 10% compared with the yield of the prawns of the comparative example.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
