Ten Hot Issues in the Global Shrimp Industry

(Summary description)In 2017, total global shrimp production exceeded 4.3 million tons, an increase of approximately 7.5% year-on-year. Among them, China, India, Ecuador, Vietnam, Thailand, Indonesia and other six major producing countries exceeded 80% of global shrimp production. More than 80% of China's farmed shrimp production comes from Penaeus vannamei. So far, Penaeus vannamei has been developed in China for more than 20 years and has formed a huge industrial chain. However, in recent years, the disease of Penaeus vannamei has been endless. According to the survey data of the Global Aquaculture Alliance (Figure 1), diseases and aquaculture costs are the main difficulties and challenges facing global South American aquaculture. How to improve the survival rate of P. vannamei farming and reduce the cost of farming is a necessary way to improve the international competitiveness of P. vannamei farming in China!



With the world's leading bio-fermentation technology, the Biochemical Business Unit of the Xijie Group has uniquely developed and produced a single Bacillus aerobic fermented protein powder, Soytide, at home and even globally. Suyopeptide is an aerobic solid-state fermented soybean meal product of Bacillus. Bacillus grows fast and has strong protease secretion ability. It is the preferred strain for soybean meal fermentation. Bacillus fermented products have complete degradation of anti-nutritional factors (Figure 2) and crude protein The characteristics of high, high digestion and absorption rate, and good water stability (Figure 3). Suyide contains 107 high-temperature-resistant bacillus, and there are still live bacteria after high-temperature granulation or even puffing (Figure 4). After feeding, aquatic animals improve their intestinal health, enhance immunity, improve water quality and reduce shrimp mortality . Through the practice in the culture of Penaeus vannamei, we found that Suyopeptide can replace fishmeal in shrimp culture and reduce the cost of culture; it has significant effects in enhancing shrimp intestinal health, reducing mortality and improving water quality.



Study on the feasibility of substituting fast peptide for fish meal

1. Experimental design

        Choose 480 healthy Penaeus vannamei juveniles, initial weight 0.5g, 3 repeats per feed treatment, 40 shrimps per repeat. The diet of juvenile shrimp includes a control group (fish meal group) and three test groups (speed peptide, fast peptide (sterilized) and fermented soybean meal D instead of part of the fish meal group). The dietary formula is shown in Table 1. The experiment uses full feeding, feeding 4 times a day for 8 weeks. The test environment is 27.0 ± 1 ℃, equipped with a seawater circulation device (salinity 33ppt).

2.1 Effect of Suyopeptide on Growth Performance of Juvenile Shrimp

Regardless of whether it is sterilized or not, Su Yi peptide has successfully replaced 9 points of fish meal. The non-sterile Su Yi peptide group also significantly increased the weight gain and specific growth rate of Penaeus vannamei (P <0.05), After sterilization, the fast peptide still improved the production performance of Penaeus vannamei to a certain extent. The results showed that the improvement of the production performance of Litopenaeus vannamei benefited from the degradation of probiotics and product antigens.

2.2 Effect of Su Yi peptide on nonspecific immunity of juvenile shrimp

There was no significant difference in the inhibition rate of superoxide dismutase between the groups (P> 0.05), but the lysozyme activity of the juvenile shrimp in the fast benefit peptide group was significantly higher than that in the fish meal and fermented soybean meal group D (P <0.05). Among them, the lysozyme activity of the Su Yi peptide (sterilized) group was significantly higher than that of the fermented soybean meal D group, and it was also improved to a certain extent compared with the fish meal group (Figure 6).

Study peptides applied to the survival rate and water quality improvement of Penaeus vannamei

1. Experimental design

Select 120 healthy Penaeus vannamei, the initial weight is 4.08 + 0.12g, 3 replicates in each group, 10 juvenile shrimps in each replicate. The diets were divided into control group, control & probiotic group (control group (+)), fish meal replacement group (speed peptide group), fish meal replacement & probiotic group (speed peptide (+)), in which probiotics were derived from A commercial brand B (Table 2). The test uses full feeding, feeding 4 times a day, the test period is 4 weeks. The test environment is 27.0 ± 2 ℃, equipped with sea water circulation device (salinity 33ppt).

2.1 The effect of Suyopeptide on the survival rate of juvenile shrimp
 
In the fourth week of the experiment, the replacement of the test water was stopped, and the mortality rate of Penaeus vannamei increased in each group. The mortality rate of the control group was the highest, up to 50%, which was significantly higher than that of the other three groups (P <0.05). However, there was no significant difference in the survival rates of the Suyeptide group, Suyeptide (+), and Control group (+). The survival rate of the Suyeptide group was higher than 60%, slightly higher than that of the control group (+). Survival rate (Figure 5).
 
2.2 The water regulating effect of Su Yi peptide
 
One week later, the NO2 concentration in the Suyipeptide group and the Suypeptide (+) group was significantly lower than that of the control group (P <0.05). At the same time, the Bacillus in the Suyotide group controlled the NO2 concentration in the water better than that used in this experiment A commercial brand B. In the second and fourth weeks of the experiment, the number of Bacillus per milliliter of water in the Suyeptide group and the Suyide (+) group was significantly higher than that of the control group (P <0.05).
 
  in conclusion
 
1. The improvement of the production performance of Suyopeptide on Penaeus vannamei benefits from the probiotic and antigen degradation in the product.
 
2. Suyi peptide improves the water quality environment of Penaeus vannamei culture while enhancing immunity and improving the survival rate of Penaeus vannamei.
