Pond crab and vegetable mutualism breeding method

Abstract

The invention discloses a pond crab and vegetable mutualism breeding method. According to the method, a terrestrial vegetable planting technique and a pond crab aquaculture technique are combined, vegetables are planted on the water surface, pond crabs are bred under the water surface, nutrient substances in a pond are absorbed by the aid of the vegetables, water eutrophication degree is reduced,water is purified, shading and cooling effects in a high-temperature period are achieved, good ecological environments are provided for the pond crab, nutrient substances such as inorganic salt decomposed by residual feed baits fed in the breeding process of the pond crabs, excrement of aquatic animals, aquatic plant remains and the like are continually provided for growth of the vegetable, mutualism effects are achieved, benefits are increased, ecology is improved, and environments are protected. According to the breeding method, breeding water can be effectively and sufficiently used, breeding environments are improved, income-increasing ways of farmers are widened, risks of single planting and breeding are reduced, worry of consumer groups for safety of agricultural product quality is eliminated, and market competitiveness of agricultural products is enhanced.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a cultivation method for symbiosis of crabs and vegetables in ponds. Background technique [0002] Crab and vegetable symbiosis is a new type of compound farming system. It combines aquaculture and hydroponics, two completely different farming techniques, through ingenious ecological design, to achieve scientific synergy and symbiosis, so as to realize crab farming without changing water. There is no water quality concern, and the ecological symbiosis effect of growing vegetables normally without fertilization. [0003] In the traditional culture of river crabs, with the accumulation of excrement and residual bait of aquatic products such as river crabs, the ammonia nitrogen in the water body increases, and the toxicity gradually increases. In the crab-vegetable symbiosis system, river crabs are cultured in eutrophic water bodies. With the help of microporous pipeline oxyg...

Problems solved by technology

Because there are crabs, shrimps, fish and other aquatic products in the crab-vegetable symbiosis system, no pesticides can be used. A little carelessness will cause the death of crabs and other aquatic products and beneficial microbial populations and the collapse of the system
