The aquaculture industry continues to grow, with a gradual shift from small-scale to high-density factory farming, which increases the demand for sustainable protein sources in fish and shrimp feeds. Krill is one of the most abundant species on earth. It is rich in 17.56% protein, unsaturated fatty acids and 8 kinds of amino acids needed by the human body, Krill meal plays an important role in the Food, Medicine and Chemical. Studies have shown that krill meal can be used as a feed attractant. It contains omega-3 fatty acids combined with phospholipids and highly digestible peptides. The source is sustainable, and it is naturally pure and stable. Therefore, adding krill meal to fish and shrimp feed can promote growth and increase yields. Especially in feeds low in fishmeal, the phagocytic properties of krill meal can improve palatability and improve growth performance.
The sustainability of feed ingredient sources is an increasingly important factor for the aquaculture industry, which is why the use of Antarctic krill helps salmon farmers reduce their reliance on expensive and limited supplies of fishmeal. Is krill a good fish food? Here are the advantages of krill meal in aquaculture
* Krill meal can be used as an effective feed attractant and growth promoter for fish and shrimp.
* Krill is a gregarious shrimp-like crustacean that is primarily used in feed formulations in the form of high-protein krill meal.
* Krill meal is a feed attractant and a growth promoter for fish and shrimp.
* Krill meal is a sustainable marine alternative to fish meal and is characterized by a high content of omega-3 phospholipids.
* In shrimp farming, krill can increase shrimp yield and enhance stress resistance without increasing production costs.
* In fish farming, krill not only increases yield, but also improves fillet quality and overall fish health.
Krill meal is a brown-orange powder processed from Antarctic krill caught in the Southern Ocean, containing about 60% protein and nutritionally balanced amino acids, and about 25% fat, including a large number of Phospholipids (about 40%), omega-3 fatty acids (EPA and DHA) and astaxanthin esters. Astaxanthin not only acts as a colorant, it is also a potent antioxidant that counteracts oxidative stress and damage to proteins, fats and DNA by scavenging free radicals. In addition, krill meal is rich in chitin and soluble compounds from the shell, such as trimethylamine oxide (TMAO), free amino acids and nucleotides, which act as feed attractants. Partial replacement of fish meal with krill meal in the feed can stimulate feeding, thereby promoting the growth of fish and shrimp.
