Freshwater Fish Counts for all Species, all Areas and all Years

PLEASE NOTE: This dataset has been superseded by the 'Freshwater fish surveys (NFPD)' dataset and is now Retired. As of March 2020 All data formerly available in 'Freshwater Fish Counts for all Species, all Areas and all Years' is now available from the new dataset. The abstract below provides a historical reference for 'Freshwater Fish Counts for all Species, all Areas and all Years' at the point of retirement.

National Fish Populations Database (NFPD): Freshwater Fish Counts for all Species for all Areas and all years. This is for Approval for Access product AfA347. NFPD consists of information collected from fisheries monitoring work on rivers, lakes and transitional and coastal waters (TraC). This monitoring work is undertaken by the Environment Agency.

This particular dataset reports fish counts per run, total fish counts, Carle and Strub population estimates for quantitative surveys and log abundance data (where applicable) for ALL Species (including hybrids) caught on each freshwater survey for all areas and years. Site and survey information and surveys where zero fish were recorded are also included.

Note: The initial version of this dataset (published February 2016) did not contain Carle and Strub population estimates for quantitative surveys or surveys where zero fish were recorded. Attribution statement: © Environment Agency copyright and/or database right 2016. All rights reserved.

请注意：本数据集已被'淡水鱼类调查（NFPD）'数据集所取代，现已退役。自2020年3月起，'所有物种、所有区域和所有年份的淡水鱼类计数'中所有可用的数据均可在新数据集中获取。以下摘要提供了关于退役时的'所有物种、所有区域和所有年份的淡水鱼类计数'的历史参考。国家鱼类种群数据库（NFPD）：包含所有区域和所有年份所有物种的淡水鱼类计数。此为访问批准产品AfA347。NFPD由河流、湖泊、过渡性和海岸水域（TraC）的渔业监测工作收集的信息组成。此类监测工作由环境署执行。该特定数据集报告了每次运行的鱼类计数、鱼类总数、Carle和Strub种群估计量（适用于定量调查）以及所有物种（包括杂交种）在每次淡水调查中捕获的鱼类（适用于所有区域和年份）的日志丰度数据。还包括站点和调查信息，以及记录为零鱼类的调查。注意：本数据集的初始版本（2016年2月发布）不包含定量调查或记录为零鱼类的调查的Carle和Strub种群估计量。归属声明：© 环境署版权和/或数据库权利2016。版权所有。
