The application of betaine hydrochloride in aquaculture is mainly reflected in improving the vitality of fish and shrimp, promoting growth, improving meat quality, and reducing feed efficiency.
1. Feeding attraction
Betaine has a sweet and fresh taste similar to amino acids, which can effectively stimulate the sense of smell and taste of aquatic animals, significantly improve the palatability of feed, and promote food intake.
Especially during the juvenile stage or environmental stress (such as high temperature, low dissolved oxygen), betaine can help animals adapt to feed faster.
2. Promote growth
Betaine promotes the secretion of digestive enzymes, enhances the digestion and absorption of nutrients such as protein and fat, and accelerates growth.
As a methyl donor, betaine participates in metabolism in the body, reducing the consumption of essential amino acids (such as methionine) and indirectly lowering feed costs.
3. Regulating osmotic
Betaine can help fish and shrimp maintain cell osmotic pressure balance in high or low salt environments, reduce energy consumption for osmotic regulation, and improve survival rates.
Betaine can enhance animal tolerance under stress conditions such as sudden temperature changes and deterioration of water quality.
In summary, the application of betaine hydrochloride in aquaculture is multifaceted, which can not only improve aquaculture efficiency but also enhance the quality of aquatic products, and is of great significance for promoting the sustainable development of aquaculture.
