L-ascorbate-2-phosphate, or ascorbyl-2-phosphate or AAP, is a stable vitamin C derivative. It is commonly used as a feed additive in fish, salmon, shrimp, and crab diets. Here are some benefits of using L-ascorbate-2-phosphate in the feeding of these aquatic species:
- Antioxidant activity: L-ascorbate-2-phosphate is a potent antioxidant, helping protect cells and tissues from oxidative damage. It can scavenge free radicals and reactive oxygen species, reducing oxidative stress. By including L-ascorbate-2-phosphate in the diet, fish, salmon, shrimp, and crabs can benefit from enhanced antioxidant defence mechanisms, promoting overall health and reducing the risk of cellular damage.
- Immune system support: L-ascorbate-2-phosphate plays a crucial role in supporting the immune system of aquatic species. It aids in the production and function of immune cells, such as lymphocytes and phagocytes, which are involved in defending against pathogens and diseases. By including L-ascorbate-2-phosphate in the diet, the immune response of fish, salmon, shrimp, and crabs can be strengthened, leading to improved disease resistance and overall immune function.
- Collagen synthesis: L-ascorbate-2-phosphate is involved in the synthesis of collagen, a structural protein necessary for the integrity of connective tissues, skin, scales, and other structural components in aquatic species. Including L-ascorbate-2-phosphate in the diet supports collagen synthesis, contributing to healthy skin, improved wound healing, and overall structural integrity.
- Stress mitigation: L-ascorbate-2-phosphate supplementation has been associated with stress mitigation in fish, salmon, shrimp, and crabs. It helps regulate stress responses and aids in maintaining overall well-being during stressful conditions such as handling, transportation, or changes in environmental conditions.
- Improved growth and development: L-ascorbate-2-phosphate plays a role in the growth and development of aquatic species. It is involved in various metabolic processes, including the synthesis of hormones and enzymes that support growth. By providing an adequate supply of L-ascorbate-2-phosphate, growth rates can be improved, leading to better production outcomes in aquaculture.
- Enhanced nutrient absorption: L-ascorbate-2-phosphate has been shown to enhance nutrient absorption in the intestine of aquatic species. It promotes the absorption of minerals, such as iron and calcium, and improves the utilization of other nutrients in the diet. This contributes to improved nutrient availability and overall nutrient utilization.
The inclusion levels of L-ascorbate-2-phosphate in the diets of fish, salmon, shrimp, and crabs should be based on factors such as the species, life stage, health status, and specific nutritional requirements. Careful formulation and consideration of other dietary components are necessary to achieve the optimal benefits of L-ascorbate-2-phosphate supplementation. It’s important to note that while L-ascorbate-2-phosphate provides benefits to aquatic species, the specific requirements and response to supplementation may vary between different species and their unique physiological needs. Consulting with an aquaculture nutritionist or veterinarian experienced in the specific species is recommended to determine the appropriate inclusion levels and benefits of L-ascorbate-2-phosphate in the diets of fish, salmon, shrimp, and crabs.
