Aquaculture equipment and aquaculture method

Abstract

The invention is applicable to the technical field of aquaculture, and provides aquaculture equipment and an aquaculture method. The aquaculture equipment comprises a water pipe network, at least onebreeding container and at least one impeller pump; the breeding container comprises a hollow part, a plurality of layers of breeding rooms used for aquatic product living are arranged on the hollow part, the hollow part communicates with the aquaculture chamber through a through hole; and the at least one impeller pump is used for mixing water and gas and discharging the gas in a water-gas mixtureto obtain water rich in dissolved oxygen, and the obtained water rich in dissolved oxygen is pumped into the hollow part through the water pipe network. According to the aquaculture equipment and theaquaculture method, water pumped into the breeding chamber is the water rich in dissolved oxygen, and therefore bubbles are avoided, the oxygenation effect is excellent, and growth of freshwater shrimps is facilitated; and moreover, the water rich in dissolved oxygen enters the breeding chamber through the through hole, a large flow speed cannot be generated, and the impeller pump is further located at the position far away from the breeding container, and therefore generated noise cannot affect the growth of freshwater shrimps.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to aquaculture equipment and a cultivation method. Background technique [0002] The cultivation of freshwater shrimp requires the planting of aquatic plants such as submerged plants and floating leaves in the pond. Aquatic plants can not only provide food sources for freshwater shrimp, but also play a role in purifying water quality. At the same time, they can also provide places and spaces for shelling, hiding and phototaxis for freshwater shrimp. Therefore, there is a saying that "to raise a pond of shrimp well, one must first plant a pond of grass well". [0003] However, the large-scale planting and multiplication of aquatic plants in ponds will also bring some disadvantages. During the day, due to photosynthesis, the dissolved oxygen in the pond is supersaturated. At night, due to the stop of photosynthesis, the aquatic plants undergo dark reactions, which ne...

Problems solved by technology

[0006] Due to the existence of aquatic plants, water wheels and flushing aeration devices have limited improvement in the fluidity of shrimp pond water, and the effect of oxygenation is poor. Moreover, freshwater shrimps are more sensitive to water flow rate, and a large flow rate is not conducive to the growth of freshwater shrimps. ; At the same time, the noise of the water wheel and the flushing type aeration device is large when it is running, which will also affect the growth of freshwater shrimp

The microtube and the inflatable head inflate the water, and a large number of aquatic plants will also block the gas, making the inflatable range limited. In addition, when the air bubbles in the water rise, they will bring the oxygen-enriched water to the surface, and the freshwater shrimp does not like air bubbles. Mainly live on aquatic plants, the actual oxygenation effect is limited, and cannot meet the oxygen demand of freshwater shrimp
