Description:
The use of United States Defense Meteorological Satellite Program Operational Linescan System (DMSP-OLS) data has enabled the precise location of the distribution of the global light-fishing fleet over a six month period in relation to the large and general mesoscale oceanography of the ecological provinces where they occur. The squid catch in these light fisheries can be identified to genera or species in seven ecological provinces where DMSP-OLS imagery reveals light-fishing activities. The DMSP-OLS data provide the information needed to review the relationship between the squid fisheries using lights and other fisheries for finfish with better spatial resolution than has been previously possible using data for FAO statistical areas alone. This chapter demonstrates that 62–70%, and possibly up to something 〈96, of the world squid catch can be accounted for in the light fisheries identified in the images. This provides the opportunity of being more specific about possible interactions between cephalopod fisheries and declining groundfish stocks and allows the hypothesis about the inverse relationship between the trends in these fisheries. The ability to visualize the spatial distribution of fishing fleets and their movements over time with DMSP-OLS data has implications for the assessment and management of the exploited squid stocks.
