Catalogue of Defra Historical Catch and Effort Charts: Six Decades of Detailed Spatial Statistics for British Fisheries - PDFs

PDFs of unpublished historical 'Statistical Charts' held at the Centre for
Environment, Fisheries and Aquaculture Science (Cefas), Lowestoft, UK. These
charts provide annual and monthly fisheries statistics at a fine spatial scale
for the period 1913-81 (excluding both World Wars). More specifically, they
show the annual and monthly landings and catch rates per fish species, and the
fishing effort for various components of the British commercial fishing fleet.
These values are indicated separately for each rectangle of 1° longitude by
30' latitude (equivalent to International Council for the Exploration of the
Sea [ICES] rectangles) as well as for the entire area charted (generally
equivalent to ICES fishing areas).

存放于英国洛斯托夫特环境、渔业和水产科学中心（Cefas）的未发表历史‘统计图表’PDF文件。这些图表以精细的空间尺度提供了1913-1981年（排除两次世界大战期间）的年度和月度渔业统计数据。具体而言，它们展示了各类鱼种的年度和月度捕捞量和捕捞率，以及英国商业渔船队的不同组成部分的捕捞努力程度。这些数值分别以1°经度、30'纬度（相当于国际海洋探险理事会[ICES]的矩形）的每个矩形以及整个绘制的区域（通常相当于ICES捕鱼区）的形式单独表示。
