Prawn bait and preparation method thereof

Abstract

The invention relates to a prawn bait and a preparation method of the prawn bait. The prawn bait comprises the following components in percent by weight: 40-55% of soybean cake powder, 15-25% of fish meal, 12-22% of flour, 5-13% of bran, 2-7% of prawn chaff and 0.5-2% of sodium humate. The preparation method comprises the following steps: taking the components according to the ratio, crushing, sieving by 40-mesh sieve, mixing uniformly, granulating and drying in the sun. The prawn bait provided by the invention has the advantages that the preparation method is simple, the soybean cake powder is used for replacing a great amount of fish meal, i.e., the plant protein is used for replacing partial animal protein, so that the cost of the materials is greatly reduced; since all the components act mutually, the amino acid can be balanced, convenience is brought for the absorption of the prawn, and rapid growth of the prawn can be enhanced, so that the body weight is increased rapidly; and the trace elements needed by the prawn growth can be supplemented, and the immunocompetence is improved, so that the survival rate is increased.

Description

technical field [0001] The invention relates to a prawn bait and a preparation method thereof. Background technique [0002] Prawns are arthropods. Prawns are rich in nutrition, and their meat is soft and easy to digest. They are excellent food for people who are weak and need to take care of themselves after illness. Prawns are rich in magnesium, which plays an important role in regulating heart activity. It can protect the cardiovascular system very well. It can reduce the cholesterol content in the blood, prevent arteriosclerosis, and at the same time expand the coronary arteries, which is beneficial to the prevention of high blood pressure and myocardial infarction. [0003] As people's demand for prawns is increasing, naturally bred prawns can no longer meet the market demand, and artificially cultured prawns, because protein is an indispensable nutrient to maintain the normal structure and function of prawns, therefore, shrimp farming has a great impact on protein.

Problems solved by technology

The current bait for prawns is mainly fishmeal. With the gradual expansion of the scale of the prawn farming industry, the demand for fishmeal is also gradually increasing, which promotes the increase in the price of fishmeal, thereby increasing the cost of prawn farming.

At present, there are also baits that reduce the amount of fishmeal, but the weight gain of prawns fed with this bait is slower and the survival rate is lower
