Abstract

The invention discloses functional feed used for inhibiting growth of gonads of Nibea albifloras and a preparation method thereof. The fish feed comprises the following raw materials: super steamed fish meal, wheat flour, cottonseed meal, fish oil, corn protein powder, distiller's grain protein feed, bean pulp, beer yeast, vital gluten, phospholipid oil, squid ointment, spray-dried blood cells, monocalcium phosphate, bentonite, castor seed kernels, special fish microelements, choline, mildew preventive, special fish multivitamin, vitamin, antioxidant, inositol and carnitine, wherein every 1000 kg of raw materials contain 8.3 kg-9.85 kg of bentonite and 6.5 kg-8 kg of castor seed kernels. The fish feed is low in cost, and can effectively inhibit the growth of the gonads and the natural ovulation of the Nibea albifloras in the growth period of the gonads of the Nibea albifloras to promote weight growth and improves economic benefit of culturing. The preparation method of the fish feed is simple and convenient in operation and is beneficial for improving culturing efficiency.

Description

technical field [0001] The invention specifically relates to a functional feed for inhibiting gonad development of yellow croaker and a preparation method thereof. Background technique [0002] Yellow croaker [Nibea albiflora (Richardson)] belongs to the order Perciformes, Totoabaidae, and genus crocodile. It is a mid- and lower-level fish in the coastal waters and is widely distributed along the coast of China. Its meat is delicious, and it is one of the favorite fishes used by coastal residents in my country. At present, it is widely cultured in cages in the coastal areas of Zhejiang, Guangdong and Fujian. However, during the breeding process of large yellow croaker, yellow croaker ovulates due to natural sexual maturity from May to July every year. During this period, it consumes a lot of nutrients and energy, and its weight gain is slow, which is very uneconomical for commercial fish farming. At present, there is no report on the functional feed for controlling the grow...
