摘要：
A cephalopod fishery forecasting method in northwest African waters based on environmental factors, including the following steps: step 1: acquiring catch production statistical data from cephalopod fisheries in northwest African waters of many years； step 2: acquiring marine environmental data corresponding to the catch production statistical data, the marine environmental data including sea surface temperature (SST) and sea surface height anomaly (SSHA)； step 3: studying the relationship between the operating haul, the operating output ratio and the average output per haul in each interval as indexes of a central fishery and the marine environmental data of step 2； and step 4: establishing suitability indexes (SI) of different environmental factors, and calculating habitat suitability indexes (HSI) under different weight cases by using an expert assignment method, thus obtaining distribution waters of the central fishery of cephalopod fisheries in northwest African waters for forecasting the central fishery.
