Characteristics of 425 Norwegian study lakes

Morphometric and climatic as well as trout yield data (i.e., grams of brown trout per 100 m2 of survey net per night) from 425 lakes in Norway, Northern Europe. "LakeNumber" refers to individual lake numbering by the Norwegian Water Resources and Energy Directorate (NVE; www.nve.no). Lake morphometry data (area, shoreline development, altitude, coordinates in UTM33) is obtained from NVE database. The lake climatic and catchment data (mean July air temperature, NDVI = Normalized Difference Vegetation Index, and terrain slope) is obtained and measured as described by Finstad et al. (2014; DOI: 10.1111/ele.12201). "Stocking" and "Regulation" refer to presence/absence of brown trout stocking and water level regulation for hydropower, respectively. "GillnetSeries" refer to type of gillnet series used for catching brown trout, whereas "FishRichness" and "FishCommunity" refer to total number of recorded fish species and fish community type present in the lake (see the main article for description of the latter). The remaining binary data indicates presence/absence of different fish species coexisting with brown trout at the time of the survey fishing.

北欧挪威的425个湖泊的形态测量、气候及褐鳟产量数据（即每夜每100平方米调查网的褐鳟捕获克数）。"LakeNumber"指代挪威水资源与能源管理局（Norwegian Water Resources and Energy Directorate, NVE；www.nve.no）对单个湖泊的编号。湖泊形态测量数据（面积、岸线发育度、海拔、UTM33坐标系坐标）取自NVE数据库。湖泊气候与集水区数据（7月平均气温、归一化差异植被指数（Normalized Difference Vegetation Index, NDVI）、地形坡度）按照Finstad等人（2014；DOI: 10.1111/ele.12201）的研究方法获取与测算。"Stocking"与"Regulation"分别指代褐鳟人工放流与水力发电水位调控的存在与否。"GillnetSeries"指代用于捕获褐鳟的刺网系列类型，而"FishRichness"与"FishCommunity"分别指代调查记录的鱼类物种总数与湖泊内现存的鱼类群落类型（后者的详细说明见主论文）。其余二进制数据指代调查捕捞时与褐鳟共存的各鱼类物种的存在与否。
