A nighttime water quality dissolved oxygen prediction method suitable for an aquaculture pond

Abstract

The invention discloses a nighttime water quality dissolved oxygen prediction method suitable for an aquaculture pond. The nighttime water quality dissolved oxygen prediction method comprises the steps of 1) establishment of water quality data and meteorological data source channels, 2) collection and processing of water quality data and meteorological data, 3) establishment of a dissolved oxygenprediction model and 4) prediction of nighttime water quality dissolved oxygen. The invention aims to solve the problem that oxygen deficit easily occurs at night in the water body of an aquaculture pond. taking the pond water body dissolved oxygen concentration at night as a prediction target; The device is simple in structure and convenient to use, meets actual breeding production conditions andmanagement requirements, can predict the concentration of dissolved oxygen in other breeding ponds at night on the basis of a small amount of online water quality monitoring instruments and equipmentin combination with online meteorological monitoring data and water quality data obtained by daily pond inspection of managers, and greatly reduces the equipment cost of water quality monitoring andearly warning of the breeding farms.

Description

technical field [0001] The invention relates to the field of pond culture, in particular to a method for predicting the amount of dissolved oxygen in water quality at night suitable for culture ponds. Background technique [0002] Pond aquaculture is an important source of aquatic products in my country and occupies an important position in the entire aquaculture. With the development of aquaculture in the direction of scale and intensification, the breeding density continues to increase and the amount of feeding increases, resulting in deterioration of water quality, and the phenomenon of death of farmed fish due to lack of oxygen occurs from time to time, especially at night in hot summer days , the risk of hypoxia in pond water is greater. [0003] Although there are dissolved oxygen monitoring instruments and equipment that can monitor the dissolved oxygen concentration in pond water in real time, due to the high price of these monitoring instruments and equipment, and ...

AI Technical Summary

Problems solved by technology

However, the intensity of solar radiation changes frequently, especially in summer, when the weather often changes suddenly, so it is very difficult to accurately predict the concentration of dissolved oxygen in the water body in the next period based on the current water quality and meteorological data

[0006] 2. It is necessary to install real-time water quality monitoring equipment in the pond, which cannot reduce costs. For large farms, a large number of monitoring equipment requires a lot of manpower and material resources for maintenance

Dissolved oxygen in the water body is rapidly consumed at night on high temperature days in summer, so the lack of oxygen in the water generally occurs at night in summer, and it is not easy to observe at night, often causing dead fish due to lack of oxygen
