Growth and development are the most basic biological processes of animals, and crustaceans are no exception. Due to the existence of chitin exoskeletons, researches on the growth and development of crustaceans mostly focus on the regulation and control of molting mechanisms, and a lot of research results are obtained. It is undeniable that the molting mechanism does play an important role in the growth and development of crustaceans. It is also to be clearly understood that the growth of crustacean carcasses is responsible for molting. From this perspective, molting is merely an outward manifestation of crustacean growth. Therefore, the identification of important genes of crustacean body growth not only helps to understand the basic biological process of crustacean growth and development, but also has important production significance for improving the yield and quality of crustaceans by molecular means.
Macrobrachium nipponensis (Macrobrachium nipponense) commonly called freshwater shrimp and river shrimp belongs to Macrobrachium, brachialidae and Macrobrachium. Has the characteristics of strong adaptability, high growth speed, strong fecundity, large individual, rich nutrition and the like, and is an important freshwater economic shrimp in China. According to the 'annual book of Chinese fishery statistics in 2017', the annual output of freshwater shrimps cultured in China is 272,592 tons. The cultivation of the macrobrachium nipponensis becomes one of the important means for increasing the production and creating income for fishermen, and plays an important role in the aquiculture in China. With the recent continuous expansion of the culture scale, macrobrachium nipponensis has the phenomena of production performance reduction and germplasm resource degradation, wherein the individual miniaturization is particularly prominent, and finally, the specification of commercial macrobrachium nipponensis is reduced, the quality of the macrobrachium nipponensis is seriously influenced, and the macrobrachium nipponensis becomes one of the bottlenecks of the development of the macrobrachium nipponensis culture industry.

Selecting 60 adult macrobrachium nipponensis with strong activity, uniform individuals and weight of about 2g respectively, evenly dividing the adult macrobrachium nipponensis into two groups (30 per group), wherein one group is an experimental group (RNAi group), namely the obtained dsRNA-CARP-1 solution, and the other group is a DEPC water group control group. The injection dose of the experimental group and the control group is 5 mug/g; air is filled in the glass jar before the experiment for temporary culture, the water temperature is 25 ℃, so that the culture environment of the laboratory is adapted, and the snail and artificial bait are fed in the morning and at night every day.
dsRNA injection and growth parameter detection
At an injection dose of 5. mu.g/g, dsRNA-CARP-1 solution was injected into the pericardial cavity from the basal part of the cephalic turbinate of Macrobrachium nipponensis, and DEPC water was injected into the control group. The intervention time was 4 weeks, once weekly. Muscle tissues were taken at 7d, 14d, 21d and 28d, respectively, and stored in RNA storage solutions. Finally, the total RNA of each sample is extracted and inverted into cDNA. The interference efficiency is calculated by detecting the change of the expression level of CARP-1 relative to a control group by adopting a fluorescent quantitative PCR technology. The body weights of the control group and the experimental group were measured at the end of the experiment, and the data were analyzed (see fig. 1, fig. 2, and table 1).
Interference efficiency is expressed amount after interference/expression amount before interference
As shown in FIG. 1, the expression level of CARP-1 in male Macrobrachium nipponensis in the experimental group was decreased by 88.81%, 86.72%, 85.55% and 91.80% at 7d, 14d, 21d and 28d after the interference, respectively, as compared with the expression level of muscle in the control group.
As shown in FIG. 2, the expression level of female Macrobrachium nipponensis CARP-1 in the experimental group was decreased by 87.52%, 88.82%, 89.522% and 86.95% at 7d, 14d, 21d and 28d after the interference, respectively, as compared with the expression level of muscle of Macrobrachium nipponensis in the control group.
The results show that the dsRNA-CARP-1 dissolving solution effectively reduces the expression level of CARP-1.
TABLE 1 changes in molting individuals and mean body weight in Macrobrachium nipponensis RNAi experiments
As shown in table 1, the numbers of molts of male and female shrimps in the RNAi-interfered group were 25 and 22, respectively, while the numbers of molts of male and female shrimps in the control group were 12 and 10, respectively. Compared with a control group, the average body weight of male and female shrimps in the RNAi interference group is increased by 0.31g and 0.29g respectively.
The results show that the interference of the CARP-1 gene can shorten the molting cycle and accelerate the growth of the macrobrachium nipponense, so the CARP-1 plays an important regulation and control function in the growth and development process of the macrobrachium nipponense.
