Abstract
This interactive version of the Atlas presents the global distribution of catches by gear from 1950 to 2012, at 5° latitude by 5° longitude resolution, of those tuna and tuna-like species for which this distribution is generally well known on the global scale. These species consist of the so-called principal market tunas and some billfishes.
The atlas of tuna and billfish catches is an interactive web-based mapping tool. It uses geographic information system (GIS) technology to enable users to map and display global catches of major tunas and billfishes by fishing gears an 5° by 5° degrees resolution.
FIGIS.
To select the range of years and quarters, use the sliders available along bottom and right edges of the map. Select at least one gear types and one species and the preferred aggregation method. Click the Map button to see results. Subsequent changes to one of the time slider are immediately reflected on the map. Due to the amount of data, it may take some time to obtain the result, please be patient. The animations panel allows creating an animated sequence of maps of catches by year or quarter.
Each cell in the map is defined through a 6 digits number: "XYYZZZ". X is the Quadrant (1=NE, 2=SE, 3=SW and 4=NW), YY is Latitude and ZZZ is Longitude. Latitude and longitude define the corner of the cell nearest to the point where the Equator is crossed by the Greenwich Meridian. For further information please refer to Section G in CWP Handbook of Fishery Statistical Standards.
