Embodiment Construction

[0007] The following will be described in detail as an embodiment of the present invention for easy implementation.

[0008] Take by weighing 30kg of trimethylamine hydrochloride, 30kg of betaine, 12kg of dimethyl-β-thiidine propionate, 7kg of citric acid, 7kg of taurine, 7kg of sodium glutamate and 7kg of glycine, and grind these seven components into fine powder (over 200 mesh), and then mix uniformly in a mixer (requiring coefficient of variation ≤ 5%), which is the turbot food attractant of the present invention.

[0009] From April 15, 2007 to June 14, 2007, turbot (initial weight: 4.01±0.10g) was cultured in Qingdao, Shandong. Prepare 3 kinds of feeds such as nitrogen and other energy, fish meal control group feed (3 repetitions) is protein source with fish meal, does not add food attractant of the present invention, contains 70% high-quality red fish meal in this feed formula; Food attractant blank Group feed (3 repetitions) is protein source with fish meal and soybean...

Abstract

The invention relates to feeding attractant used for turbot. The feeding attractant is characterized by consisting of trimethylamine hydrochloride, betaine, dimethyl-Beta-propiothetin, citric acid, taurine, sodium glutamate and aminoacetic acid; the weight percent (w / w) ranges of the components are as follow: 25 to 35, 25 to 35, 10 to 20, 5 to 10, 5 to 10 and 5 to 10. The feeding attractant used for turbot is used as additive in turbot feed, and only 0.5 percent to 1.5 percent of the feeding attractant is added. The feeding attractant used for turbot has the advantages that: (1) the feeding attractant is used in the turbot feed, and only a small amount of the feeding attractant is added; (2) the feeding attractant can obviously promote the ingestion and the growth of the turbot; meanwhile, can reduce residual bait, and is good for environment protection; (3) the feeding attractant can greatly reduced the consumption of fish meal in the feed, and reduce the feed cost; (4) the raw materials of the invention have stable sources, low cost and simple production process.

Description

technical field [0001] The invention relates to a feed additive, in particular to a food attractant for turbot fish. Background technique [0002] Turbot (Scophthalmus maximus L.) belongs to the family Bothidae and the genus Scophthalmus, and is a rare and precious flatfish native to the North Sea, Baltic Sea and Mediterranean coasts of Europe. my country began to introduce and domesticate it in 1992. At present, it has become an important new species of mariculture in the northern coastal areas. Turbot has delicious meat, small viscera, thick body, many edible parts, high commodity value and broad market prospect. However, with the expansion of breeding scale in recent years, the price of turbot has declined. Therefore, reducing the cost of turbot farming by reducing feed costs is an important issue for aquatic science and technology workers. In order to fundamentally reduce the cost of turbot feed, it is necessary to select other animal and vegetable protein sources to p...
