Special compound feed for breeding parent shrimps of Litopenaeus vannamei

Abstract

The invention discloses a special compound feed for breeding parent shrimps of Litopenaeus vannamei. The special compound feed contains the following components in percentage by weight: 20%-45% of whole squid meal, 5%-20% of Peru fish meal, 5%-15% of copepod dry powder, 2%-5% of enzymolysis fish soluble meal, 2%-8% of spirulina powder, 3%-10% of fly maggot meal, 5%-20% of oyster powder, 1%-4% of enzymolysis beer yeast powder, 1%-4% of sea rhodotorula, 5%-20% of alpha-starch, 1%-3% of soybean lecithin, 1%-5% of squid liver oil, 0.5%-2% of calcium dihydrogen phosphate and 1%-3% of a compound premix. The special compound feed is specially used during the breeding of the parent shrimps of Litopenaeus vannamei and is used for supplying nutrients required by the parent shrimps in the breeding stage; by adding multiple components which can mutually generate synergistic interaction effects, the digestion and utilization of the main nutrients are promoted, the immune capacity and health condition of prawns can be improved, the gonadal maturation quality is improved, and the hatching rate of fertilized eggs and the survival rate of larvae are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed and breeding, and more specifically relates to a special compound feed for breeding of Litopenaeus vannamei broodstock. Background technique [0002] Litopenaeus vannamei, commonly known as Penaeus vannamei, is a euryhaline crustacean native to the Americas. This species has rapidly become an aquaculture species due to its large output, high meat yield, easy intensive farming, and delicious meat. The upstart in the industry. In the past two decades, my country's Litopenaeus vannamei aquaculture output ranks first in the world, and it is an important force in the development of the blue agricultural economy industry. The continuous shrimp farming dilemma in recent years highlights the huge demand and market call for excellent shrimp seedlings of Litopenaeus vannamei and their broodstock breeding germplasm resources. In recent years, the cost of importing broodstock from the United States...

Problems solved by technology

The common shrimp feed used in market farming cannot meet the nutritional needs of the broodstock cultivation stage, especially the high-quality sources of protein, fat, vitamins and other related nutrients

At present, the nutrient sources used to cultivate broodstock in the domestic market are directly fed with fresh baits such as squid, clamworm, and oysters. These baits are not only expensive, but the quality is unstable and the supply is limited. They have specific nutritional and functional requirements and are easy to carry germs and viruses. During the feeding period, it is easy to damage the water quality and breed pathogens, which brings a greater potential threat to the management of broodstock breeding and the cultivation of shrimp seedlings.
