Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0023] figure 1 It is a flow chart of the method for predicting the output of freshwater aquaculture fish of the present invention, and the specific steps are as follows:

[0024] Access to historical freshwater farmed fish production data;

[0025] Obtain meteorological data for the corresponding period of historical freshwater aquaculture fish production data, including temperature, precipitation, sunshine duration and humidity;

[0026] Stepwise regression analysis is a method in multiple regression analysis. Stepwise regression analysis is often used to establish the optimal or appropriate regression model, so as to study the dependencies between variables more deeply. The purpose of the present invention using stepwise regression analysis is to screen out more important influencing factors from many...

Abstract

The invention belongs to the technical field of fish production estimation and discloses a method for predicting the production of freshwater cultured fish, which can realize accurate prediction of the production of freshwater cultured fish. Collect historical meteorological data and historical freshwater aquaculture fish production data, and use stepwise regression analysis to screen meteorological factors that have a significant impact on freshwater aquaculture fish production. In order to judge whether to introduce or delete new variables without changing the overall significance of the equation, Therefore, a coefficient is set to distinguish the introduction and deletion of new variables. Using these significant meteorological factors to establish a forecasting model for predicting freshwater aquaculture production, the use of this model can provide assistance for the production management of freshwater fish aquaculture.

Description

technical field [0001] The invention belongs to the technical field of fish output estimation and relates to a method for predicting the output of freshwater cultured fish. Background technique [0002] Today's climate change has become a major environmental issue that seriously affects human production and life. Climate change has wide-ranging impacts on future ecosystems, socio-economy. Putting more pressure on fisheries and aquaculture. Global warming is one of the main effects of climate change. The increase in temperature brings a series of changes in hydrology and hydrogeography to water bodies. The increase in temperature leads to increased evaporation, increased cloud thickness, and reduced sunlight. These changes have important implications for aquaculture. [0003] At present, research on climate change at home and abroad mainly focuses on the impact of climate change on crops and marine fishery resources, ignoring the impact on freshwater aquaculture fish. Co...
