Problems solved by technology

Argentine squid is an annual marine organism. Rational fishing and utilization of Argentine squid resources can provide food and protein for humans, but overfishing may lead to a break in the food chain and damage the ecology
A problem with current Argentine squid stock management is that traditional fishery stock assessments use commercial catch data
Commercial fishing data are time-delayed and inaccurate, with low spatio-temporal resolution
Although commercial fishing data can provide scientific decision-making assessments for medium- and long-term fishery resource management, medium- and long-term fishery resource management alone is not enough for annual marine organisms

Abstract

The invention relates to a method for extracting fishing intensity spatial information of a squid fishing ground. The method comprises the following steps: acquiring ship position trajectory data of all squid fishing ships in the squid fishing ground based on AIS data; mining operation states of all the squid fishing boats according to the obtained ship position trajectory data of the squid fishing boats by adopting two factor data of speed and brightness; and calculating the fishing effort of the squid fishing boat according to the operation states of all the squid fishing boats. The fishing intensity information of the squid fishing ground can be mined.

Description

technical field [0001] The invention relates to the technical field of fishery resource management, in particular to a method for extracting spatial information of squid fishing ground fishing intensity. Background technique [0002] Argentine squid, also known as Argentine squid, is an oceanic shallow sea species, mainly distributed on the continental shelf and slope of the Southwest Atlantic Ocean. It is an important cephalopod resource and an important fishing target for squid fishing in China. plays an important role. Argentine squid is an annual marine organism. Reasonable fishing and utilization of Argentine squid resources can provide food and protein for humans, but overfishing may lead to a break in the food chain and damage the ecology. A problem with the current management of squid stocks in Argentina is that traditional fishery stock assessments use commercial catch data. Commercial fishing data are time-delayed and inaccurate, with low spatio-temporal resoluti...
