From table 2 it can be seen that the yield of red shell shrimp is 141Kg/ mus in experimental group, the yield of blue or green shell shrimp is 126Kg/ mus, total yield It is 5534 yuan/mu to measure as 267Kg/ mus, income；The yield of red shell shrimp is 135Kg/ mus in experimental group, and the yield of blue or green shell shrimp is 115Kg/ mus, total output are 250Kg/ mus, and income is 4844 yuan/mu.And experimental group than control group feed cost more than 200 yuan/ Mu or so, COMPREHENSIVE CALCULATING experimental group than control group income more than 490 yuan/mu, amplification is up to more than 10%；Carried simultaneously using the present invention The blue or green shell shrimp accounting 47.2% that the feed of confession obtains, and control group is 46.0%；Use 7 money that feed provided by the invention obtains with On cray accounting 37.5%, and control group be 31.6%, i.e., using the present invention forage feed cray（Change the shell phase）'s Condition is more preferable, has higher competitiveness.
Cultivate embodiment 2
Using 20-40m2Little pond raising mode to food-intake, shelling the parameter such as survival rate and water quality check, other With cultivation embodiment 1, the data of the cultivation embodiment are carried out using sampling observation estimation form, certain error be present.Take juvenile prawn Shelling and is averaged at data for the first time for shelling and sexal maturity three times；Wherein, average feeding amount is the feed feelings according to cray Condition is fed, and it is the weight ratio with cray（Daily）, survival rate is the average value of survival rate twice, and water quality data is Start to feed the numerical value after 5 days.
Table 3
　 Experimental group Control group
Average feeding volume 4.21% 4.03%
Survival rate 93.30% 89.70%
Transparency 40cm 36cm
Dissolved oxygen 6.83mg/L 6.16mg/L
Phytoplankton 24550000/L 20390000/L
Zooplankter 37420000/L 29340000/L
Feeding volume, survival rate, transparency, dissolved oxygen, plant of swimming from table 3 it can be seen that experimental group for control group, is averaged The numerical value such as thing and zooplankter is improved, and what the raising of above-mentioned numerical value not only can directly improve cray changes shell success rate, also Contribute to the growth of pasture and water etc.（Whole growth period can improve the water surface coverage rate 3-5% of pasture and water）, changing for cray is promoted indirectly Shell survival rate.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
