Abstract

The invention relates to a method and a system of pool culture. The method for regulating water quality of pool complex culture comprises the following steps: the water body discharged from a fish pool (1) inflows into an ecological crab pool (3) after being treated by a biological purifying channel (2), the water body inflows into a water body purifying equipment of clay and ceramsite (4) by power after purifying treatment in the ecological crab pool (3) and finally refluxes into the fish pool (1). The system for regulating water quality of pool complex culture comprises the following steps:arraying a plurality of fish pools (1) and crab pools (3) in a way of juxtaposition with one side provided with a biological purifying channel (2) and the other side is provided with the water body purifying equipment of clay and ceramsite (4); communicating the fish pools (1), the biological purifying channel (2) and the ecological crab pool (3) subsequently through a cannula device (5), wherein, the ecological crab pool (3) is connected with the water body purifying equipment of clay and ceramsite (4) through a water pump (6), the water body purifying equipment of clay and ceramsite (4) is connected with the fish pool (1) through an inlet channel (7). The invention is the culturing method for regulating complex water quality, which has the characteristics of low cost, low energy consumption and high efficiency and conforms to the pool culturing model of ecological principle.

Description

(1) Technical field

[0001] The invention relates to a pond culture mode construction technology, in particular to a method and a control system for adjusting and controlling the water quality of compound culture in ponds. (2) Background technology

[0002] Pond aquaculture is the main way of aquaculture in China and occupies an important position in my country's aquaculture industry. However, problems such as environmental pollution, water resource waste, and food safety in traditional pond aquaculture have become increasingly prominent, and these problems have seriously restricted the sustainable development of pond aquaculture.

[0003] There are many studies on pond culture models at home and abroad. In my country, the "Sankey fishery" model that emerged in the Pearl River Delta more than 400 years ago is recognized as a model of ecological fishery. In 1992, it was praised by UNESCO as "a rare beauty in the world and a virtuous circle model". Since the 1980s, my country...
