Landscape Position Project at North Temperate Lakes LTER: Fish Mercury Level 1998 - 1999

As part of the Landscape Position Project, yellow perch were collected for mercury and isotope analysis by a combination of angling, beach seining, vertical gill net, fyke net and electrofishing in the summers of 1998 and 1999. A total of 183 yellow perch from 43 study lakes with approximate length of 150 mm were analyzed. Sampling Frequency: one survey on each lake in late June through August of 1998 or 1999 Number of sites: 43本数据集作为景观位置项目（Landscape Position Project）的一部分，研究人员于1998年与1999年夏季，联合采用垂钓、海滩围网、垂直刺网、袋形陷网（fyke net）及电渔法采集黄鲈（yellow perch）样本，用于汞与同位素分析。本次研究共对来自43个研究湖泊的183尾体长约150毫米的黄鲈进行了分析。采样频率：1998年或1999年的6月末至8月期间，对每个湖泊开展1次调查。采样点位数量：43个
