The invention provides a method for forecasting the
fishing situation of Symplectoteuthis australis in the
South China Sea, which comprises the following steps: different points are selected in the sea area where the
fishery situation prediction of Symplectoteuthis australis needs to be carried out, and environmental factors affecting the
habitat quality of Symplectoteuthis australis at corresponding positions are obtained; the environment factors affecting the
habitat quality of Symplectoteuthis australis are analyzed; according to the model of different seasons and different environmental factors and adaptability index, the adaptability index of the selected point position is obtained; according to the model of
habitat adaptability index and seasonal adaptability index, the habitat adaptability index of selected sites is obtained; the habitat adaptability index distribution map of Symplectoteuthis
ulna is obtained by
image processing of habitat adaptability index corresponding to theselected points in the
fishery forecasting sea area, and the range of Symplectoteuthis
ulna fishery could be predicted. The method of the invention can make short-term prediction of the fishery situation of the
South China Sea kite
squid and reflect the habitat change of the
cephalopod resources in a short time, and the accuracy rates of forecasting the fishery situation of the
South China Sea kite
squid in different seasons are 83%, 86%, 88% and 90%, respectively.
