Technical Field

The invention relates to the field of eel culture feed, in particular to eel seedling culture bait and a preparation process thereof.

Background

Eel is a rare edible fish with warm water, has high nutritive value, is called as 'ginseng' in water, and enjoys a great name at home and abroad. Eel is a kind of river-lowering fish, and is bred by laying eggs in the deep sea of congeneric eel matured in autumn every year. The eel fries are subjected to bait dressing from spring to the vicinity of river mouths and grow in fresh water for 1 week, and can grow to 15 cm in spring of the next year and have the weight of about 5 g. Eel is fierce in sexual condition, greedy in eating, good in mobility, pronounced in daytime and night, strong in phototaxis and loves flowing water. When the water temperature is above 12 ℃, the eel starts to eat. The white eel mainly ingests zooplankton, aquatic insects and organic debris. Young eels with a weight of about 5 g begin to prey on fry, and young eels with a weight of 100 g can catch small fishes and shrimps. Adult eel staple food animal feed. The artificial feed can be used for artificial feeding.

The eel breeding industry in China starts in the seventies of the last century, and the existing problems are that the formula is unscientific, the nutrition is unbalanced, the quality is poor, the feed conversion rate is low, the breeding period is prolonged, and the breeding cost of farmers is increased; the processing technology is imperfect, the fineness is poor, the mixing is not uniform, the digestion and absorption rate of the eel is low, the feed loss is caused, and the environment is polluted.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide eel seedling culture bait with natural raw material components, proper proportion and remarkable growth promoting effect according to the digestive physiological characteristics of eels and a preparation process thereof.

The technical scheme adopted by the invention for solving the technical problem is as follows:

the eel seedling raising bait consists of the following raw materials in parts by weight: 50-60 parts of imported fish meal, 10-15 parts of soybean meal, 1-5 parts of cuttlefish powder, 2-6 parts of hemoglobin, 20-30 parts of cassava starch, 1-6 parts of beer yeast, 1-3 parts of lecithin, 1-3 parts of monocalcium phosphate and 1 part of marine fish premix.

Preferably, the raw material components are as follows: 50 parts of imported fish meal, 10 parts of bean pulp, 4 parts of cuttlefish powder, 5 parts of blood globulin powder, 25 parts of cassava starch, 3 parts of beer yeast, 1 part of lecithin, 1 part of calcium dihydrogen phosphate and 1 part of marine fish premix.

Preferably, the imported fish meal and the cuttlefish powder are both crushed dry powder raw materials and are good protein raw materials of the eels; the soybean meal is expanded soybean meal after soybean oil is extracted by a vegetable oil factory; the cassava starch is standard cassava starch of a starch factory; the beer yeast is processed by beer fermentation; lecithin is prepared by defatting semen glycines.

The preparation process of the eel seedling culture bait comprises the following steps:

(1) weighing the following raw materials in parts by weight: imported fish meal, soybean meal, cuttlefish powder, globulin powder, cassava starch, beer yeast, lecithin, calcium dihydrogen phosphate and marine fish premix;

(2) uniformly mixing the imported fish meal, the bean pulp, the cuttlefish powder, the blood globulin powder, the cassava starch, the beer yeast, the lecithin, the monocalcium phosphate and the marine fish premix weighed in the step (1), sequentially carrying out coarse crushing and ultrafine crushing, then carrying out secondary mixing, and packaging to obtain the eel seedling culture bait.

The invention has the beneficial effects that:

according to the digestive physiology and feed characteristics of eel, the invention takes green, environmental protection, nutrition and energy conservation as starting points, and utilizes the superfine grinding technology to improve the feed quality and the feed conversion rate. The bait disclosed by the invention is aromatic in flavor, rich in nutrition, high in feed conversion rate, scientific in compatibility and synergistic, and can meet the growth requirements of eel in a seedling stage.

Detailed Description

The present invention will be further described with reference to specific examples to assist understanding of the invention. The method used in the invention is a conventional production method if no special provisions are made; the starting materials used, unless otherwise specified, are conventional commercial products.
