Water environment evaluation method and water environment evaluation system for culture of Chinese mitten crabs

Abstract

The invention provides a water environment evaluation method for the culture of Chinese mitten crabs. According to the invention, the culture cycle of Chinese mitten crabs is divided into a pluralityof culture stages according to the shell shedding cycle of Chinese mitten crabs. The method comprises the steps of S1, acquiring water environment parameters for the culture of Chinese mitten crabs during any culture stage, and obtaining water environment features according to the change of water environment parameters over the time and the relationship between water environment parameters and a water environment threshold value; S2, inputting feature vectors into a staged water environment classification model, and obtaining the valuation result of the water environment for the culture of Chinese mitten crabs. According to the invention, corresponding water environment features are obtained from the water environment parameters acquired during any culture stage. Meanwhile, water environment features are adopted as feature vectors to be inputted into the staged water environment classification model. In this way, the evaluation result of the water environment during the culture stagesof Chinese mitten crabs can be obtained. Moreover, according to the evaluation result of the water environment, the water environment is correspondingly adjusted. As a result, farmers for the cultureof Chinese mitten crabs can be assisted to make production decisions.

Description

technical field [0001] The present invention relates to the field of agricultural Internet of Things information processing and analysis, and more specifically, to a water environment evaluation method and system for river crab farming. Background technique [0002] River crab, scientific name Chinese mitten crab, has high nutritional value and economic value, and occupies a high position in China's aquaculture species. In 2016, the national river crab breeding water area exceeded 10 million mu, and the annual output exceeded 800,000 tons . After more than 20 years of development of river crab farming, conventional farming has been promoted and popularized on a large scale, and the production and benefits of farming have also been continuously improved. However, with the continuous expansion of the farming area and scale, the market price trend of river crabs is changing. Benefits are on a downward trend. In this context, the cultivation of river crabs puts forward higher ...

AI Technical Summary

Problems solved by technology

River crab farming has developed from the initial resource release type farming to the current intensive high-density intensive farming, and has developed from decentralized to regional intensive. However, there are still many problems in the field of river crab precision farming: for example, when making production decisions, still rely on individuals Experience guides production; the data collected by using the Internet of Things technology is simply stored and queried, and the analysis and processing are not sufficient to guide the actual production.

[0004] Although the Internet of Things technology has achieved good monitoring of the water environment, due to insufficient data analysis, the utilization rate of a large amount of real-time monitoring data is very low
