Culture pond for parent prawns of prawns and water changing method

Abstract

The invention discloses a culture pond for parent prawns of prawns and a water changing method thereof. The culture pond is characterized by comprising a culture pond bottom arranged in a circular oroval funnel shape, a water inlet pipe attached to the pond bottom wall, a sewage draining exit located in the center of the pond bottom, a water filtering mesh and a high-value live bait recycling device connected with the sewage draining exit. According to the culture pond for the parent prawns of the prawns, vortexes are formed through the impact force of inlet water, residual baits, excrement,prawn shells and dead prawns in the pond are gathered to the sewage draining exit, the parent prawns have the reverse water habit and can actively jack water flow to move away from the sewage drainingexit, when a sewage draining valve is opened, impurities gathered in the pond are discharged along with waste water, available live baits are sorted out from the high-value live bait recycling device, and the available live baits are washed to be used again. The water changing method is simple in design, scientific and reasonable, water changing is automatically controlled by additionally arranging an automatic control device, the working intensity of operators is relieved, and damage and death of the parent prawns in the water changing process are avoided.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a breeding pond for broodstock prawns and a water changing method. Background technique [0002] At present, the scale of industrial seedling breeding is expanding day by day, and the volume of the breeding pond is also increasing. Taking aquatic shrimp breeding as an example, in the process of aquatic biological seedling breeding, bait should be fed into the pond 4-6 times a day, including sand. For silkworms, oysters, squid, and soft pellet feeds close to live bait nutrition, the seedlings cultivated in the pond need to continuously replenish new water and discharge old water to ensure water quality requirements. When pumping and changing water from the breeding pond, the common process is to open the sewage The valve pumps water, lowers the water level, and then enters the breeding pond with a sieve. Use the sieve to stir the water to roll up the impurities to be cleaned and take the ...

[0002] At present, the scale of industrial seedling breeding is expanding day by day, and the volume of the breeding pond is increasing. Taking the aquatic breeding shrimp as an example, in the process of aquatic biological seedling breeding, bait should be fed into the pond 4-6 times a day, including sand. For silkworms, oysters, squid, and soft pellet feeds that are close to the nutrition of live bait, the seedlings cultivated in the pond need to continuously replenish new water and discharge old water to ensure water quality requirements. The valve pumps water, lowers the water level, and enters the breeding pond with a screen. Use the screen to stir the water to roll up the impurities to be cleaned and take the net away. This process needs to be carried out every morning and evening. This method of changing water will cause great damage to the cultured animals. Large, disturbing the water change process will cause damage to the breeding process of the cultured animals, and secondly, the labor cost is too large, which is not in line with long-term interests
