Description

Sea urchin rapid fattening bait and preparation method thereof Technical Field The invention relates to sea urchin bait and a preparation method thereof, in particular to sea urchin quick fattening bait and a preparation method thereof, and belongs to the technical field of aquaculture feeds. Background The economic value of sea urchins is mainly represented on the gonads thereof, namely sea urchin yellow. The color, fullness, flavor and nutritional value of sea urchin yellow are key indicators for determining the commodity grade of sea urchin. Fattening is carried out by feeding high-efficiency special baits in a period of time before sea urchin harvesting, and the method is a core means for improving the cultivation benefit. At present, the bait for sea urchin cultivation and feeding is mainly divided into three types, namely natural fresh large algae (such as kelp and undaria pinnatifida), simply processed dry algae powder and few attempted compound feeds. However, these baits have obvious drawbacks, in particular: 1. unbalanced nutrition, fixed nutrition component of single algae, and difficulty in meeting quick gonad of sea urchin The development has high requirements on proteins, specific glycogen and trace elements, and the fattening efficiency is low; 2. the water quality pollution is serious, fresh algae and dry algae powder are very easy to be dispersed and spoiled after being added into water, the utilization rate of baits is low, a large amount of residual baits and metabolic wastes seriously pollute the culture water body, the culture environment is deteriorated, and the disease risk is increased; 3. The nutrition cannot be accurately enhanced, namely the nutrition components of the natural bait cannot be enhanced and adjusted according to the special requirements of the sea urchin fattening stage; 4. the fresh algae are inconvenient to store and feed, the fresh algae need to be transported by a cold chain, the shelf life is short, the dry algae powder is easy to float and the sinking property is poor. Although research is carried out on artificial compound baits, most of the main stream of aquatic granulated feed ideas, and the processing process often involves high-temperature granulation, so that thermosensitive nutrients are easily destroyed, and the hardness of the prepared feed is possibly unsuitable for sea urchin ingestion. Disclosure of Invention Aiming at solving the defects of the prior art, the invention aims to provide the bait which has comprehensive nutrition, good palatability and extremely high stability in water and can pertinently promote the rapid development of the gonad of the sea urchin, and the preparation method of the bait. In order to achieve the above object, the present invention adopts the following technical scheme: A sea urchin rapid fattening bait consists of the following raw materials in parts by weight: 10-25 parts of kelp powder, 10-25 Parts of undaria pinnatifida powder, 5-15 Parts of ulva pertusa powder, 5-15 Parts of mussel powder, 8-20 Parts of corn flour, 1.5 To 4.5 parts of gelatin powder, 30-50 Parts of purified water. Preferably, the material comprises the following raw materials in parts by weight: 15-20 parts of kelp powder, 15-20 Parts of undaria pinnatifida powder, 8-12 Parts of ulva pertusa powder, 8-12 Parts of mussel powder, 12-16 Parts of corn flour, 2-3.5 Parts of gelatin powder, 35-45 Parts of purified water. More preferably, the material comprises the following raw materials in parts by weight: 18 parts of kelp powder, 17 Parts of undaria pinnatifida powder, 10 Parts of ulva pertusa powder, 10 Parts of mussel powder, 15 Parts of corn flour, 3 Parts of gelatin powder, 40 Parts of purified water. Or comprises the following raw materials in parts by weight: 15-parts of kelp powder, 20 Parts of undaria pinnatifida powder, 12 Parts of ulva pertusa powder, 8 Parts of mussel powder, 16 Parts of corn flour, 2.5 Parts of gelatin powder, 38 Parts of purified water. The preparation method of the sea urchin rapid fattening bait comprises the following steps: 1. adding gelatin powder with formula amount into purified water with formula amount heated to 85-98deg.C, and continuously stirring until gelatin powder is completely dissolved to obtain transparent gel matrix liquid, and maintaining the temperature at 60-75deg.C for use; 2. Mixing kelp powder, undaria pinnatifida powder, ulva pertusa powder, mussel powder and corn powder according to the formula amount, and stirring uniformly to obtain a mixed dry material for later use; 3.
