Proteases in Aquaculture: Efficacy and Function
Below are the main functions of Protease in Aquaculture
1、 Accelerate feed digestion and improve breeding efficiency
Proteases are enzymes that hydrolyze proteins, breaking them down into small molecules of amino acids and peptides, making it easier for fish to absorb and utilize proteins in feed. Therefore, adding Protease in aquaculture can accelerate the digestion and absorption of feed, increase the growth rate and weight of fish, and improve aquaculture efficiency.
2、 Reduce the nitrogen and phosphorus content of aquaculture excrement and alleviate water pollution
In aquaculture, excessive feed can cause fish to be unable to fully digest and absorb, and the excrement contains a large amount of nutrients such as nitrogen and phosphorus, resulting in eutrophication of the aquaculture water and causing water pollution. Protease can break down difficult to digest proteins in feed, allowing them to be absorbed and utilized by fish, reducing the phenomenon of low immunity and high mortality rate. At the same time, it also reduces the nitrogen and phosphorus content of aquaculture excrement, effectively reducing the degree of water pollution.
3、 Other functions
In addition to the above functions, Proteases also have other functions:
1. Improve feed quality: Adding an appropriate amount of Protease can reduce the undigested protein content in feed and improve feed quality.
2. Promote healthy growth: Proteases can promote the metabolic activity of fish, improve their immunity, and enhance their overall health.
In summary, Proteases have a wide range of applications in aquaculture, which can improve feed utilization and breeding efficiency, reduce water pollution, and ensure the healthy development of the ecological environment.
Let's take a look at a more specific example:
The mechanisms of action of Protease in shrimp farming mainly includes the following aspects:
Promote feed digestion: Protease can accelerate the digestion speed of feed, allowing shrimp to absorb nutrients more efficiently. Proteases can break down peptide bonds in proteins, as well as breaking down large protein molecules into small peptides and amino acids that are more easily digested and absorbed by shrimp.
Accelerate feeding speed: The addition of Protease can shorten the feeding time of shrimp, improve feed utilization, and save time for breeders.
Thickening shrimp intestines: Protease helps to repair the intestines of shrimp, promote the growth of intestinal villi, enhance intestinal function, and effectively prevent problems such as white stool and diarrhea.
Enhancing shrimp vitality: By increasing the palatability and conversion rate of feed, Protease can enhance shrimp vitality, making them healthier and more active.
Promoting shrimp growth: The addition of Protease can promote shrimp growth, making it grow faster and better.
Reduce feed coefficient: The use of Protease can reduce the amount of feed used, lower costs, and improve aquaculture efficiency.
Reducing environmental pollution: The use of Proteases in aquaculture can help reduce the accumulation of organic waste in ponds, improve water quality, and lower the risk of shrimp diseases.
Enhance resistance: Certain enzymes such as glucanase can stimulate the immune system of shrimp, improve their resistance, and help shrimp better resist diseases.
