Problems solved by technology

However, at present, most seawater fish still rely on feeding chilled fish or small miscellaneous fish for farming. This farming mode causes a lot of waste of natural fishery resources and serious pollution to the water environment. It is urgent to use compound feed for farming. model to achieve sustainable development of fisheries and aquaculture
However, due to insufficient international and domestic research on marine fish nutrition, many commercial feeds for marine fish have poor food-attracting properties, and farmed fish do not want to eat, slow feeding speed and low food intake.
As a result, the growth rate of seawater fish is slow during the breeding process, the commercial specifications cannot be reached in the normal breeding cycle, and the mortality rate remains high.
This situation has seriously hindered the further development of marine fish farming and feed manufacturing

Embodiment Construction

[0015] The feed attractant for mariculture fish is formulated as follows, which is based on the amount added per ton of feed: crystal taurine 1000g, L-glycine 800g, L-alanine 800g, L-glutamic acid 1200g, L- Aspartic acid 1200g, betaine hydrochloride 2000g, dimethyl-β-thiatin propionate (DMPT) raw powder 1500g, defatted fish soluble protein powder 6500g. The order of feeding is to put the defatted fish soluble protein powder first, then add the other raw materials mentioned above one by one, mix thoroughly every time a new raw material is added, and finally mix evenly to prevent classification. Promptly finally obtain the feed attractant for seawater fish of the present invention, and the addition amount of this product in every ton of seawater fish feed is 15 kilograms.

[0016] It has been proved by multiple breeding experiments in seawater fish feeds such as Japanese perch, crocodile, oval pomfret and grouper that the feed attractant for seawater cultured fish of the present...

Abstract

The invention relates to a feed additive, in particular to a feed promoting agent for seawater cultured fishes, which comprises the raw materials in weight ratio in the terms of addition per ton of feed: 300-1200g of crystal taurine, 300-1000g of L-glycine, 500-1000g of L-alanine, 500-1200g of L-glutamic acid, 800-1500g of L-aspartate, 500-3000g of betaine hydrochloride, 1000-2000g of dimethyl-beta-propiothetin (DMPT) crude powder and 1100-8000g of degreased condensed fish soluble protein powder. Proved by multiple culture tests in seawater fish feeds, such as Japanese sea bass, sciaenops ocellatus, trachinotus ovatus, garrupa and the like, the feed promoting agent for seawater cultured fishes is capable of remarkably enhancing the food intake of the seawater fishes to the composite feed by above 10 percent and quickening the intake speed as well as remarkably improving the stress-resisting capability of the cultured objects; and the cultured the seawater fishes have the advantages of high survival rate, bright color and strong stress resistance.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed attractant for seawater cultured fish. Background technique [0002] China is the world's largest aquaculture country and aquatic product trade country, and it is also the only country in the world where aquaculture output exceeds fishing output. The output of aquaculture aquatic products accounts for 70% of the world, and the export value of aquatic products ranks first in the world for 6 consecutive years and 8 consecutive years. It ranks first in the export of bulk agricultural products in my country, and aquaculture occupies a very important position in the national economy. In recent years, my country's aquaculture industry has developed vigorously, especially the fourth wave of aquaculture represented by marine fish farming is in the ascendant. However, at present, most seawater fish still rely on feeding chilled fish or small miscellaneous fish for farming. This farming mode cause...
