Background
Along with the continuous improvement of living standard, the demand of aquatic products on the market is also continuously increasing. Wherein, the freshwater shrimps are high-grade high-quality aquatic products, have delicious taste and rich nutrition, are suitable for both the old and the young, are greatly advocated culture varieties, and are very expensive in the long triangle and the surrounding areas.
At present, freshwater shrimps can grow only under fresh and clean water environment conditions, the standard of the environmental conditions is high, a large amount of aquatic plants such as submerged plants are generally needed to be planted, proper density space is needed to be kept, the freshwater shrimps are relatively small in individual, the yield per unit area is low, the price of the freshwater shrimps is very high, the freshwater shrimps are produced in low yield, the annual yield per mu is only about forty to fifty kilograms, the proportion of the large-size freshwater shrimps is low, and the direct reason for the phenomenon is the early propagation phenomenon of the freshwater shrimps in the cultivation process.
Specifically, the optimal water temperature for breeding freshwater shrimps is about eighteen to thirty ℃, the breeding temperature is suitable for the freshwater shrimps in the temperature range, and when the length of the shrimp larvae reaches about two centimeters after the freshwater shrimps are put in culture, the freshwater shrimps are continuously bred, so that a large number of shrimp larvae appear in the pond, and the breeding period is continued from summer to autumn. The large amount of early-bred shrimp fries can fight against water and bait with the initially bred shrimp fries, the feed coefficient is high, the hypoxia is easy to be caused, and the breeding period is also obviously prolonged. Due to the early propagation phenomenon, too many shrimps in the shrimp pond exceed the culture bearing capacity of the culture pond, and the growth of initially-bred shrimp fries is affected, so that the specification size difference is large. Therefore, in the current freshwater shrimp culture process, the freshwater shrimps cannot be bred and caught once like fish culture, and in the freshwater shrimp pond, a method of taking out the freshwater shrimps from the pond in a round manner is adopted, namely the grown freshwater shrimps are continuously caught and marketed regularly, otherwise, the survival rate is very low when the freshwater shrimps are eaten greatly, especially when the freshwater shrimps are peeled off, so that the total annual yield is too low, and the failure in control is very easy to cause the culture failure.
Therefore, the prior freshwater shrimp culture technical scheme has the following defects in actual use: the existing freshwater shrimp culture method has the phenomenon of early propagation in the culture process, so that the specification and the size of freshwater shrimps are greatly different.

A method for controlling the number of early-bred shrimp larvae, which is characterized by adopting the aquatic offspring seed number control system according to any one of claims 1-5, specifically comprising the following steps: the utility model provides a shrimp larva collection device, including the pump body, seal assembly, the net cover is installed to the pump body, make with the outlet pipe of the seedling remover of the input intercommunication of the pump body produces the negative pressure, when under the negative pressure condition, seal assembly orientation the outlet pipe removes, seal assembly seals the net cover is so that the aquatic body in the breed pond can not get into the net cover, and then makes accommodation chamber, seal assembly, the net cover takeover, water guide and outlet pipe constitute the communication structure jointly, thereby inhale the shrimp larva of early propagation to the outlet pipe under the negative pressure condition and pour into in the collection box with the control breed pond in the shrimp larva quantity of early propagation.
7. The method for controlling the quantity of the early-bred shrimp fries according to claim 6, further comprising the step of biological control, wherein a plurality of mixed culture net cages are arranged on the inner side of the culture pond along the ridge trend, and the mixed culture net cages are used for stocking filter-feeding fishes and/or herbivorous fishes.
8. Use of the method for controlling the number of early-bred shrimp fries according to any one of claims 6-7 in large-scale breeding of aquatic products.
