Embodiment Construction

[0031] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0032] like figure 1 As shown, a method for cultivating new strains of low-salt-tolerant Penaeus monodon, the salinity of the culture water is divided into several gradient ranges, and the median salinity of each gradient range is the first salinity range from high to low to the 5th salinity range, and the 6th salinity range to the 9th salinity range; the adjustment operation time of each salinity range corresponds to its own specific period of time; put some Penaeus monodon into the culture pond, and then Cultivate sequentially according to the corresponding periods from the first salinity range to the ninth salinity range in the step range;...

Abstract

The invention discloses a low-salt-resistant penaeus monodon new species breeding method. Low-salt-resistant penaeus monodon species can be better sorted through breeding in a salinity regulation modewithin multiple stepped ranges. According to the low-salt-resistant penaeus monodon new species breeding method, a stepped range mode, rather than a mode in which a certain low salinity value maintains invariable fundamentally, is adopted, in this way, the process in which the salinity of a breeding water body changes to a low salinity direction naturally can be simulated better, and thus the sorted penaeus monodon species has higher capability to adapt to the situation that the salinity is influenced because river water rises suddenly or rainstorm is heavy in a natural state.

Description

technical field [0001] The invention relates to a technique for cultivating a new species of Penaeus monodon, in particular to a method for cultivating a new species of Penaeus monodon resistant to low salt. Background technique [0002] Penaeus monodon is eurysalinity, can tolerate high temperature and low oxygen, and has weak adaptability to low temperature. Strong disease resistance. The individual is large, the shell is thicker, and the edible ratio is lower than that of Chinese prawns. The meat is delicious and nutritious. The body shell is relatively solid and can withstand being caught by hand. After leaving the water, it has a strong endurance to dry and expose to the air, so it can be sold as a live shrimp. Its adaptability to salinity ranges from 5 to 25, and the closer to 10, the faster the growth. Coastal and estuary beaches that are suitable for the living habits of P. monodon can be used to build ponds to raise shrimp. The water source should be pure and fr...
