Rice field shrimp aquaculture water quality control system

Abstract

Disclosed is a rice field shrimp aquaculture water quality control system. The system comprises a ridge, a rice field and a shrimp gutter. The horizontal plane of the rice field is lower than that ofthe ridge, the horizontal plane of the shrimp gutter is lower than that of the rice field, any side of the rice field is directly connected with the ridge through a connecting region, a gutterway is arranged at the position, adjacent to the ridge, of the connecting region, the connecting region is flushed with the rice field, the horizontal plane of the gutterway is higher than that of the shrimpgutter and lower than that of the rice field, one end of the shrimp gutter is divided into a settling region and a water purifying region through a baffle and a filtering baffle, the other end of theshrimp gutter is communicated with the gutterway, the water purifying region is located at the outmost end and provided with a water pump, a water outlet of the water pump stretches into the portion above the gutterway. The defects in the prior art are overcome, the food distribution uniformity inside the shrimp gutter is effectively improved, the water quality inside the shrimp gutter is ensured,and therefore the quality and meat quality of crayfish are improved.

Description

technical field [0001] The invention relates to the technical field of paddy field shrimp cultivation, in particular to a water quality control system for paddy field shrimp cultivation. Background technique [0002] Crayfish are also called Procambarus clarkii, red crayfish and freshwater crayfish. It is shaped like a shrimp and has a hard shell. The adult is about 5.6-11.9 cm long, dark red, the carapace part is nearly black, and there is a wedge-shaped stripe on the back of the abdomen. The juvenile body is uniform gray, sometimes with black ripples. Claw long and narrow. The middle part of the carapace is not separated by mesh-like spaces, and there are obvious grains on the carapace. The frontal sword has side spines or the end of the forehead sword has notches. It is a freshwater economical shrimp, which is widely welcomed by people because of its delicious meat. Because of its omnivorous nature, fast growth rate and strong adaptability, it forms an absolute comp...

Problems solved by technology

[0003] Shrimp farming in paddy fields is a co-cultivation technology of rice and crayfish. Shrimp help loosen the soil in the paddy fields by moving and foraging in the paddy fields, and eat the weeds and other aquatic organisms that consume fertilizers in the fields. This not only saves weeding labor, Elimination of mosquitoes and flies that protect humans and animals can also obtain high-quality aquatic protein and increase production and efficiency; however, there is a major technical difficulty in the existing paddy field shrimp farming process, which is how to achieve an optimal ecological balance between rice and crayfish
