Problems solved by technology

[0003] At present, the culture of Penaeus vannamei in my country tends to have two characteristics: one is intensive, high-density, high-yield culture, and requires fast growth and short culture cycle; the other is desalination culture, even in pure fresh water, plus antibiotics The non-standard use of chemical drugs in production has led to the continuous increase of drug-resistant strains and the decline in the

Abstract

The invention discloses a natural pigment feed additive for freshwater aquaculture of vannamei. The natural pigment feed additive for the freshwater aquaculture of the vannamei comprises the following components in parts by weight: 5-9 parts of dunaliella salina powder, 5-7 parts of carrot powder, 1-8 parts of spirulina powder and 22-38 parts of pigment stabilizer. 0.1-2% of the natural pigment feed additive for the freshwater aquaculture of the vannamei by mass is added into feed for the freshwater aquaculture of the vannamei, so that the astaxanthin content in the body of the adult vannamei can be obviously improved to improve the color, and the non-specific immunity of the vannamei can be improved to reduce diseases and further the economic benefit is improved.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a pigment feed additive for freshwater culture of Penaeus vannamei. Background technique [0002] Vannamei Boone (Penaeus vannamei Boone), native to the waters of the Pacific coast of the Americas, is mainly distributed from northern Peru to the coast of the Gulf of Mexico, with the most concentrated distribution along the coast of Penaeus vannamei in Ecuador. Penaeus vannamei has the advantages of large individuality, fast growth, low nutritional requirements, and strong disease resistance. It has a strong adaptability to changes in water environment factors, has low requirements for feed protein content, has a meat yield of over 65%, and survives out of water. With the advantages of long time and other advantages, it is an excellent variety for intensive high-yield farming, and it is also the shrimp species with the highest yield per unit among the three major cultured prawns ...
