Feed for raising plagiognathops microlepis and preparation method of feed

Abstract

The invention provides a feed for raising plagiognathops microlepis and a preparation method of the feed. The feed comprises the following raw materials in percentage by weight: 20.00% of soybean meal, 20.00% of Peru fish meal, 20.00% of flour, 17.28% of rapeseed dregs, 10.00% of extruded soy bean powder, 7.78% of rice bran, 1.80% of monocalcium phosphate, 1.94% of soybean oil, 1.00% of plagiognathops microlepis premix and 0.20% of choline chloride. Compared with the prior art, the feed which is prepared by crushing and mixing twice is comprehensive in nutrition. The raised plagiognathops microlepis is high in growing speed, good in fish body shape and body color, low in feed coefficient which reaches 1.5: 1, high in anti-stress ability and long-distance transport resistant.

Description

technical field [0001] The invention belongs to the field of fishery, and in particular relates to a feed for raising pomfrets and a preparation method thereof. Background technique [0002] Pomfret slender scales, also known as Shaguzi, Huangwei Diao, Huangbanyu, etc., is an important economic fish in my country. It is a kind of fish of the genus Pomfret, mainly distributed in the Yangtze River Basin. [0003] Pomfrets are small to medium-sized fish. These fish have few diseases, delicious meat, high economic value, and a short food chain. They mainly feed on benthic algae and decaying debris that are abundant in water bodies and cannot be used by most economic fish. There is no food conflict with other main farmed fish. Therefore, by increasing the amount of stocking and making full use of the natural bait of the water body, a fairly high group production can be obtained, thereby improving economic benefits. [0004] Due to the delicious meat taste of Pleurotus chinensi...

Problems solved by technology

[0005] The traditional feed of Pleurotus chinensis either adds a lot of hormones to achieve the purpose of rapid growth of Pleurotus chinensis, but the added hormones are harmful to the human body

Moreover, the color of many artificially raised pomfrets is quite different from that in natural waters, which is not recognized by the market.

Moreover, due to the insufficient nutritional content of the feed, the health of the pomfret is poor, and the mortality rate is high in the process of fishing and transportation, which brings losses to the fishermen.
