Trachinotus ovatus body color improving compound feed

Abstract

The present invention discloses a trachinotus ovatus body color improving compound feed which consists of the following components (in weight percentage): 30%-35% of white fish meal, 10%-14% of peanut meal, 8.5%-12% of soybean protein concentrate, 10.5%-13.5% of soybean meal, 14%-18% of wheat middling, 2%-5% of squid viscera powder, 3%-5% of beer yeast, 4%-8% of fish oil, 1.5%-2.5% of soybean lecithin, 0.65%-0.95% of choline chloride, 1.2%-2% of mineral substance premix, 1%-2% of vitamin premix and 2%-5% of spirulina. Feeding the trachinotus ovatus compound feed for about eight weeks can significantly improve the body color of the trachinotus ovatus, enable the trachinotus ovatus a closer body color to wild fish, effectively improve the commercial value of the trachinotus ovatus; and the compound feed has adequate nutrition, strong palatability, can meet all the nutritional needs of trachinotus ovatus under artificial breeding condition, has high feed utilization rate, stable source of used raw materials, and is conducive for industrial production; and at the same time, the feed preparation method is simple and convenient.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed which can improve the body color of oval pomfret. Background technique [0002] Oval pomfret (Trachinotus Ovatus), commonly known as golden pomfret and yellow wax pomfret, is a warm-water fish widely distributed in all oceans of the world. Its meat is tender, nutritious and delicious, and has always been listed as a valuable edible fish. And it grows fast, it can be listed on the market in the same year, the economic benefit is remarkable, and it is very popular among farmers. It has become the main species of seawater cage culture in southern China; In 2011, my country's aquaculture output reached 80,000 tons, and the amount of compound feed used was about 100,000 tons. The cultivation of pomfret pomfret in my country has begun to take shape; wild pomfret pomfret has a bright body color, blue back and golden abdomen. Yellow, no black spots on the side of the body, orange-yellow fins,...

[0002] Oval pomfret (Trachinotus Ovatus), commonly known as golden pomfret and yellow wax pomfret, is a warm-water fish widely distributed in all oceans of the world. Its meat is tender, nutritious and delicious, and has always been listed as a valuable edible fish. And it grows fast, it can be listed on the market in the same year, the economic benefit is remarkable, and it is very popular among farmers. It has become the main species of seawater cage culture in southern China; In 2011, my country's aquaculture output reached 80,000 tons, and the amount of compound feed used was about 100,000 tons. The cultivation of pomfret pomfret in my country has begun to take shape; wild pomfret pomfret has a bright body color, blue back and golden abdomen. Yellow, no black spots on the side of the body, orange-yellow fins, and light black edge of the odd fins. Artificially cultured pomfret pomfret is fed with compound feed, its skin color becomes pale and white, and its body color degrades seriously, which seriously affects its quality. At present, there are few research reports on the body color of the ovate pomfret, so there is an urgent need to provide an artificial compound feed that can improve the body color of the artificially cultured pomfret
