Universal fixed feed for grass carp and tilapia parent fish and preparation method thereof

Abstract

The invention discloses a universal fixed feed for grass carp and tilapia parent fish and a preparation method thereof and aims at providing a fixed feed for improving nutrition, constitution, reproductive capacity of the grass carp and tilapia parent fish, improving egg cell fertility rate, hatching rate and quality and survival rate of larval and juvenile. The universal fixed feed is composed of the following raw materials including 4-10 parts of fish meal, 1-7 parts of shrimp meal, 25-45 parts of soya bean meal, 3-8 parts of corn gluten meal, 15-25 parts of high protein flour, 2-8 parts of dried brewer's grain, 3-8 parts of mixed oil, 1-4 parts of squid ointment, 1-5 parts of soya bean lecithin, 1-3 parts of monocalcium phosphate, 0.1-2.0 parts of fine bran, 0.2-0.6 part of vitamin premix, 1-4 parts of mineral substance premix, 0.01-0.1 part of vitamin E, 0.1-0.6 part of vitamin C acetate, 0.02-0.06 part of astaxanthin, 0.1-0.3 part of choline chloride, 0.01-0.06 part of yeast cell wall, 0.02-0.06 part of antioxidant and 0.02-0.06 part of mildew preventive.

Description

technical field [0001] The invention relates to a freshwater fish broodstock compound feed, in particular to a nutritious, healthy, green and environment-friendly compound feed suitable for grass carp broodstock and tilapia broodstock; it belongs to the technical field of fish feed. Background technique [0002] Grass carp is one of the main freshwater aquaculture fishes in my country. In 2011, the total output of grass carp aquaculture in China was about 4.4422 million tons. In 2012, the total output of grass carp aquaculture was about 4.7817 million tons. The total annual breeding output has increased by more than 5%, ranking first. Tilapia is one of the most widely farmed fish species in the world. It is a freshwater fish cultured species that is mainly cultivated by the world's aquaculture industry. It is known as the main source of animal protein. Since the 21st century, the global tilapia production has grown rapidly, especially from 2004 to 2009, the global production...

Problems solved by technology

Although the spawning time interval has been significantly shortened and the number of broodstock spawning has increased, this has led to the fact that most of the nutrition in the broodstock is used for the development of sex cells, the physique of the broodstock is reduced, the fecundity is weakened, the amount of spawning and the frequency of spawning are reduced, and the quality of eggs and sperm Decrease in fertilization rate, hatching rate, survival rate of larvae and juveniles, and degradation of seed resources
