Embodiment 1

[0020] The bait provided in this example is suitable for feeding at the larval stage of shrimp and crabs.

[0021] The bait is made of scallop hydrolyzate, kelp slurry, and dextrin, which are concentrated, dried, and granulated; the scallop enzyme hydrolyzate accounts for 20%, the kelp slurry accounts for 50%, and the dextrin accounts for 20%. The proportion is 30%.

[0022] After the bait prepared by the above ratio is fed, the bait is basically suspended at a depth of 0.5-1M underwater after absorbing water, which is very suitable for feeding at the larval stage of shrimp and crab.

Embodiment 2

[0024] The bait provided in this embodiment is suitable for the feeding of shrimp and crabs in the early stage of catching.

[0025] The bait is made of scallop enzymatic hydrolyzate, kelp slurry, and dextrin, which are concentrated, dried, and granulated; the scallop enzymatic hydrolyzate accounts for 10%, the kelp slurry accounts for 20%, and the dextrin accounts for 10%. The proportion is 70%.

[0026] After the bait prepared by the above ratio is fed, the bait is basically suspended at a depth of 4-5M underwater after absorbing water, which is very suitable for feeding mature shrimp and crabs in the early stage of harvesting.

Embodiment 3

[0028] The bait provided in this example is suitable for feeding in the mid-growth stage of shrimp and crabs.

[0029] The bait is made of scallop enzymatic hydrolyzate, kelp slurry and dextrin, which are concentrated, dried and granulated; the scallop enzymatic hydrolyzate accounts for 15%, the kelp slurry accounts for 35%, and the dextrin accounts for 15%. The proportion is 50%.

[0030] After the bait prepared by the above ratio is fed, the bait is basically suspended at a depth of 1.5-3M underwater after absorbing water and swelling, which is very suitable for feeding shrimp and crabs in the mid-growth stage.

[0031] In actual feeding, farmers can grasp the proportion of shrimp and crabs in different growth stages in the culture pond according to the feeding situation of shrimps and crabs in the pond, and mix and put in the bait of the above-mentioned different stages according to the ratio.

[0032] The concrete preparation method of above-mentioned bait is as follows: ...

Abstract

The invention relates to a feed and a preparing method thereof, and aims to provide a bait which can promote shrimps and crabs to eat in actively, and can promote the growth of the shrimps and the crabs. According to the technical scheme, the shrimp and crab bait preparing from a scallop zymolyte is preparing by steps of mixing, the scallop zymolyte, kelp size and dextrin, concentrating, drying and pelleting, wherein the scallop zymolyte accounts for 10-20% of the total weight, the kelp size accounts for 20-50% of the total weight, and the dextrin accounts for 30-70% of the total weight. A preparing method comprises the following steps of: preparing scallop zymolyte, preparing kelp size, and concentrating, drying and pelleting the mixed components. The bait can promote the heath growth of the shrimps and the crabs, the preparing method is scientific and reasonable, easy, convenient and feasible to operate and suitable for factory scale production.

Description

technical field [0001] The invention relates to a feed and a preparation method thereof, in particular to a shrimp and crab bait prepared from scallop enzymatic hydrolyzate and a preparation method thereof. Background technique [0002] Shrimp and crab larvae live in planktonic life, and mainly filter and feed on planktonic microalgae, protozoa and suspended particles in the water. Adult shrimp and crabs live at the bottom and mainly feed on benthic organisms. Shrimp mainly feed on bottom crustaceans and shellfish, and crabs can also prey on fish. At present, the shrimp and crab breeding water surface is expanding day by day, and the shrimp and crab feed in the limited breeding water surface is seriously insufficient, and farmers need to regularly throw bait for feeding. The bait to be fed should not only have the water smell that can cause shrimp and crabs to actively eat, but also need to be rich in nutrients that can promote the vigorous growth of shrimp and crabs.
