Problems solved by technology

However, most of the current early warning methods for aquaculture water quality focus on the study of water quality parameters such as ammonia nitrogen, nitrite, and dissolved oxygen, ignoring the prediction and early warning of calcium and magnesium ion content in aquaculture water.

Embodiment 1

[0021] From June 17th to September 25th, 2020, a water quality monitoring and prediction breeding experiment was carried out on a prawn culture pond in Magang Village, Shunde District, Foshan City, Guangdong Province. The pond area is 4 mu, and the salinity of the pond culture water body is 5ppt. The content is 100-140ppm, the magnesium ion content is 130-210ppm, the dissolved oxygen is kept at about 6.5-8.0, and the pH is 8.0-8.5. On June 17, 2020, 55,000 shrimp seedlings of Penaeus monodon with a size of about 4g / tail were stocked. Real-time monitoring of aquaculture water quality, and prediction and analysis of large ammonia nitrogen content in aquaculture water without artificial large-scale adjustment of water quality, the data analysis is as follows:

Embodiment 2

[0045] From May 15th to September 25th, 2020, another prawn breeding pond in Magang Village, Shunde District, Foshan City, Guangdong Province was tested for water quality monitoring and forecasting. The ion content is 120-200ppm, the magnesium ion content is 130-180ppm, the dissolved oxygen is kept around 6.5-8.5, and the pH is 7.5-8.5. On May 15, 2020, 100,000 shrimp seedlings of Penaeus monodon with a size of about 2g / tail were stocked. Real-time monitoring of aquaculture water quality, and prediction and analysis of ammonia nitrogen content in aquaculture water without artificial large-scale adjustment of water quality, the data analysis is as follows:

Abstract

The invention discloses a prediction and early warning method for prawn culture water quality, which comprises the following steps of continuously detecting the ammonia nitrogen content of prawn culture water, and establishing a linear equation of the ammonia nitrogen content by using continuously detected ammonia nitrogen content data to predict the numerical value of the ammonia nitrogen content in the culture water. When the predicted value of the ammonia nitrogen content exceeds 2.0 mg/L, early warning is started to continuously detect the ammonia nitrogen content of the prawn culture water body, and a linear equation of the relationship between the ammonia nitrogen content and time is established by using continuously detected ammonia nitrogen content data and is used for predicting the numerical value of the ammonia nitrogen content in the future culture water body; and when the predicted value of the ammonia nitrogen content exceeds 2.0 mg/L, early warning is started. According to data monitored in real time, the water quality change trend and short-term ammonia nitrogen content data can be effectively predicted by using a simple linear equation, water quality prediction and early warning are realized, and a scientific basis is provided for effectively improving an aquaculture water environment. The prediction and early warning method for the prawn culture water quality does not need specific software or tools, is simple and easy to operate, and is convenient to popularize in farmers.

Description

technical field [0001] The invention belongs to a water quality monitoring and analysis method. Specifically, it relates to a method for forecasting and early warning of water quality in shrimp culture. Background technique [0002] The shrimp aquaculture industry is the pillar industry of aquaculture in my country. In 2018, the total aquaculture output of freshwater shrimp in my country reached 2.64 million tons, and the total aquaculture output of marine shrimp reached 1.3 million tons. During the breeding process, most farmers adjust the water quality based on their own experience, and generally take measures only after the water quality deteriorates, which makes the health of prawns susceptible to being affected, thereby reducing the production of aquaculture. The water quality parameters that need to be paid attention to in shrimp farming mainly include ammonia nitrogen, nitrite, calcium and magnesium ion content, etc. [0003] Ammonia nitrogen accumulation often occu...
