PIKE – Distribution, extinctions and introductions of freshwater fish in Sweden

The PIKE database are assembled by Göran Englund and co-workers at the Department of Ecology and Environmental Science at Umeå University. It contains information on presence of fish species, as well as introductions of new species, extinctions and rotenone treatments. Most data has been collected by governmental agencies and individuals who have shared their knowledge and data sets. The information derives from field surveys, interviews and inquires. A few hundred lakes have been surveyed within the project to obtain complementary data. Most of the occurrence data have been collected in the period 1890-2012. PIKE also includes information on water chemistry, lake depth, lake area,and much more. Most of the lakes are found in Sweden, but Norway and Finland are also represented.

PIKE 数据库由乌普萨拉大学生态与环境科学系的 Göran Englund 及其同事汇编而成。该数据库包含了鱼类物种的分布信息，以及新物种的引入、物种灭绝和罗丹宁处理的相关数据。大部分数据由政府部门和个人收集，他们共享了他们的知识和数据集。信息来源于实地调查、访谈和查询。在项目中调查了几百个湖泊以获取补充数据。大部分的分布数据是在 1890-2012 年期间收集的。PIKE 还包括关于水质化学、湖泊深度、湖泊面积等方面的信息。大部分湖泊位于瑞典，但挪威和芬兰也有所代表。
