Sequencing-batch pond culture system and method

Abstract

The invention provides a sequencing-batch pond culture system and a method, wherein the system at least comprises a size grading unit, a fingerling rearing unit, an inlet water system, and a boiler blowdown system, wherein the size grading unit sequentially comprises a first-level culture pond, a second-level culture pond, and a third-level culture pond side by side. A first division wall between the first-level culture pond and the second-level culture pond and a second division wall between the second-level culture pond and the third-level culture pond are respectively provided with a fish passage, and each fish passage is provided with a fish gate inside. The area ratio of the fist-level culture pond to the second-level culture pond to the third-level culture pond is 7 to 3.5 to 1; the fist-level culture pond and the second-level culture pond and the third-level culture pond are respectively connected with the inlet water system and the boiler blowdown system. According to the sequencing-batch pond culture system and the method, serial production, sequencing-batch appearance on the market, and accurate culture are realized, so that aquaculture capacity is improved, and culture efficiency and benefit are increased.

Description

Technical field [0001] The present invention relates to the field of aquaculture, in particular to a sequencing batch pond culture system and method. Background technique [0002] Pond culture is the main form of aquaculture in China and the main source of aquatic product supply. In 2015, there were 2.701 million hectares of freshwater ponds in the country, with an output of 21.956 million tons, accounting for 32.8% of the country's total fishery output, and played an irreplaceable role in ensuring food safety. China has a long history of pond aquaculture and is the first country in the world to carry out pond aquaculture. China’s ecological models such as “mulberry fishery” and “cane-based fishery” and healthy aquaculture technologies such as “eight-character intensive culture method” have contributed to the world’s aquaculture industry. Made a huge contribution. Since most of China’s aquaculture ponds were constructed in the 1960s and 1970s, there are currently widespread aqu...

AI Technical Summary

Problems solved by technology

[0003] First, the traditional pond culture method is extensive, and the water environment is difficult to control, which can easily lead to deterioration of the breeding environment, sediment pollution, and low breeding production efficiency

[0004] Second, although the breeding methods such as polyculture in ponds and wheel catch and release can improve ecological efficiency, in the case of high-density farming, the impact of fish emergencies is great, the risk of breeding is high, and the breeding effect is not good

[0005] Third, the current separated ponds and raceway ponds have problems such as poor sewage collection and discharge, low feed utilization rate, and the same breeding and production methods as traditional pond farming methods, which cannot solve the problem of continuous breeding and supply of aquatic products

[0006] Fourth, the current breeding ponds or farms have problems such as unclear function classification, relying on experience for production, and extensive production management, which cannot meet the needs of precision farming
