Abstract

The invention discloses a Mauritania cephalopod fishery prediction method based on habitat indexes. According to the method, SST, SSHA and sea depth obtained by satellite remote-sensing are combined to analyze Mauritania cephalopod fishery distribution and a habitat index model thereof under different environment weights according to production statistics collected and acquired at Mauritania fishery work from 2010 to 2015, and a basis is provided for carrying out Mauritania cephalopod fishery forecasting. Relationships of the Mauritania cephalopod fishery distribution and marine environments are very close, and suitable environment ranges of work fisheries between January and April and July and December are also different to a certain extent. Optimum work fishery SST, SSHA, sea depth are 16-22 DEG C, -35-25cm and -5-5cm and 15-25m and 45-75m respectively. According to the model, degrees of impacts formed by different environment factors on the cephalopod fisheries are not the same, theSST is greatest in impacts, the SSHA is the second, and the sea depth is the last.

Description

technical field [0001] The invention relates to the technical field of cephalopod fishery forecasting, in particular to a habitat index-based forecasting method for cephalopod fishery in Mauritania. Background technique [0002] Mauritania is a country in the west of the African continent, with a long coastline and unique marine environment. Fishery is the main source of national economic income. Ocean fishery resources have 400×10 4 There is a large amount of storage, especially cephalopods, which are also the main fishing targets of my country's ocean-going fishing vessels. Carrying out research on cephalopod resources and fisheries in the waters near Mauritania is of great significance to the efficient production of my country's ocean-going trawlers. [0003] Xu Jianguo and others have explored and improved the operating tools for catching cephalopods in Mauritanian fishing grounds; Zhang Jinbao’s research believes that the development potential of fishery resources in ...
