Problems solved by technology

Although high-protein feed can speed up the growth of river crabs, the price of high-protein feed is relatively high, and the cost of breeding has increased significantly.
[0005] 3. Increase the feeding amount of artificial feed or small miscellaneous fish to increase the nutrient intake of river crabs, but excessive feeding will inevitably lead to waste of feed, increase in feeding costs and water pollution, and easily cause diseases
[0007] 5. Cultivate natural bait through fertilization or feed low-value waste as part of the bait source for river crabs and Procambarus clarkii. Although this method reduces the cost of breeding, it pollutes the water body
[0008] The nesting of Procambarus clarkii in river crab breeding ponds can increase additional income, but the diet and living habits of the nesting Procambarus clarkii are similar to those of river crabs, and the competition for food and habitat is not conducive to the survival rate and breeding of Procambarus clarkii. The size and the efficiency of nesting are improved. At the same time, Procambarus clarkii is extremely destructive to aquatic plants. After raising Procambarus clarkii in crab ponds, the aquatic plants in the pond are often eaten by a large number. Ponds lacking aquatic plants are ecologically stable. Poor sex and high morbidity, and the risk of raising Procambarus clarkii in crab ponds is obviously increased. Therefore, how to strengthen the bait guarantee and ecological stability of shrimp and crabs after raising Procambarus clarkii in crab ponds has become a problem for crab farmers. The key to higher returns

Abstract

The invention relates to preparation and application methods of fermented materials of a bait biological bed for mainly cultivating river crabs and intercropping procambarus clarkii and belongs to the technical field of cultivation. The method comprises the following steps: adding materials fermented by probiotics; and carrying out rotary cultivation to construct the bait biological bed which takes the fermented materials as main components at the bottom of a pond. The fermented materials can be directly supplied to the procambarus clarkii to eat; cultured animals and plants including tubificidae, chironomidae larvae, snails, aquatic plants and the like can be used as baits for shrimps and crabs; the abundant natural baits can be used for reducing the competition intensity of foods and inhabit domains; the survival rate of intercropping the procambarus clarkii is improved. The bait biological bed can dually supply oxygen in summer by an oxygen bottle and a micro-pore aerator and is good for improving the cultivation efficiency of demersal food organisms; the cultivated natural baits can be used for providing an extra nutrition source to the growth of the shrimps and the crabs, and are good for improving the cultivation yield and benefits of the shrimps and the crabs; meanwhile, a stable cultivation ecology can be formed by aquatic plant colonies in the pond and the cultivation risk is reduced.

Description

technical field [0001] The invention relates to a shrimp and crab nesting method that puts materials that have been fermented by probiotics into ponds, and makes the fermented materials used by river crabs, Procambarus clarkii and benthic organisms, and at the same time can promote the proliferation of aquatic plants The invention relates to a method for cultivating river crabs and nesting Procambarus clarkii by converting cheap raw materials and wastes into high-quality natural bait, which belongs to the technical field of cultivation. Background technique [0002] How to improve the efficiency of river crab farming is a common concern of crab farmers, and common measures to increase production and efficiency are: [0003] 1. Increasing the stocking density of river crabs is a common technical measure to increase production and benefits, but increasing the stocking density of crab seedlings will greatly increase the cost of breeding, and the average size of commercial crabs...
