Problems solved by technology

Not only is the input cost high, but the pond is also prone to water damage, resulting in low survival rates of crabs and shrimps and low catch rates, which eventually lead to poor harvests or even losses

Embodiment 1

[0013] A culture medium for shrimp and crab seedling ponds. The medium is prepared according to the following formula, and the proportions of the components are calculated in parts by weight: 20 parts of cow dung, 20 parts of sheep manure, 15 parts of distiller's grains, 10 parts of straw, and 10 parts of corn flour 10 parts of soybean meal, 5 parts of molasses, 5 parts of vegetable cake, 5 parts of livestock and poultry manure fermentation bacteria.

[0014] The preparation method of this culture medium is as follows:

[0015] 1) Mix cow dung, sheep dung, distiller's grains, and straw in proportion, and carry out primary fermentation at a temperature of 55-60°C and a humidity of 20-25%, until the fermentation is complete to obtain a primary fermentation product;

[0016] 2) Add corn flour, soybean meal, molasses, and vegetable cakes to the primary fermentation product in proportion, and after mixing evenly, carry out secondary fermentation at a temperature of 25~30°C and a hu...

Embodiment 2

[0022] A culture medium for shrimp and crab seedling ponds, the medium is prepared according to the following formula, and the proportions of the components are calculated in parts by weight: 24 parts of cow dung, 20 parts of sheep manure, 18 parts of distiller's grains, 8 parts of straw, and 10 parts of corn flour 10 parts of soybean meal, 3 parts of molasses, 3 parts of vegetable cake, 4 parts of livestock and poultry manure fermentation bacteria.

[0023] The preparation method of this culture medium is as follows:

[0024] 1) Mix cow dung, sheep dung, distiller's grains, and straw in proportion, and carry out primary fermentation at a temperature of 60-70°C and a humidity of 25-30%, until the fermentation is complete to obtain a primary fermentation product;

[0025] 2) Add corn flour, soybean meal, molasses, and vegetable cakes to the primary fermentation product in proportion, and after mixing evenly, carry out secondary fermentation at a temperature of 30~35°C and a hum...

Embodiment 3

[0030] A culture medium for shrimp and crab seedling ponds, the medium is prepared according to the following formula, and the proportions of the components are calculated in parts by weight: 20 parts of cow dung, 22 parts of sheep manure, 15 parts of distiller's grains, 10 parts of straw, and 10 parts of corn flour 11 parts of soybean meal, 3 parts of molasses, 4 parts of vegetable cake, 5 parts of livestock and poultry manure fermentation bacteria.

[0031] The preparation method of this culture medium is as follows:

[0032] 1) Mix cow dung, sheep dung, distiller's grains, and straw in proportion, and carry out primary fermentation at a temperature of 75-85°C and a humidity of 25-30%, until the fermentation is complete to obtain a primary fermentation product;

[0033] 2) Add corn flour, soybean meal, molasses, and vegetable cakes to the primary fermentation product in proportion, and after mixing evenly, carry out secondary fermentation at a temperature of 45~50°C and a hu...

Abstract

The invention discloses a breeding medium used for a juvenile shrimp and crab pool and a preparation method of the breeding medium.The breeding medium is prepared from, by mass, 10-30 parts of cow dung, 10-30 parts of sheep manure, 10-20 parts of distillers' grains, 5-15 parts of straw, 5-15 parts of corn flour, 5-15 parts of bean pulp, 1-6 parts of molasses, 1-7 parts of vegetable cakes and 2-6 parts of livestock excrement zymophyte.When the breeding medium is used for the breeding processes of freshwater shrimps, eriocheir sinensis and the like, a large number of fresh and good-quality aquatic organisms of water earthworms, chironomidae larvae, plankton and the like can be easily bred, good-quality bait is provided for growth of juvenile crabs, and therefore input of artificial bait is reduced, and the input cost is reduced; meanwhile, by means of the breeding medium, the purified water oxygen dissolving degree is easily increased, the water body environment is adjusted, a good ecological environment is provided for growth of shrimps and crabs, and the survival rate of shrimps and crabs is greatly increased; meanwhile, by means of the breeding medium, the water body fertility can be effectively increased, and growth of aquatic plant root systems is promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a culture medium for shrimp and crab fry ponds and a preparation method thereof. Background technique [0002] Crabs and shrimps are generally cultivated in ponds for two years. In the first year, crabs and shrimp seedlings are cultivated into crabs and shrimp species (young crabs and shrimps). In the second year, crabs and shrimp species are cultivated into crabs and adult shrimps Shrimp (commercial crab, shrimp) is on the market. Now that people's living standards have improved, freshwater prawns and Chinese mitten crabs have become popular products. For crab and shrimp farming, a large amount of feed and ice fish must be put in, and naturally fermented fertilizers need to be put in the breeding pond to adjust the fertility of the water body. Not only is the input cost high, but the pond is also prone to water damage, resulting in low survival rates of crabs and shrimps a...
