Historical Length, Weight, and Fecundity of Silver Chub (Macrhybopsis storeriana) in Western Lake Erie
收藏资源简介:
This data set provides a table of length, weight, sex, and estimated fecundity of Silver Chub Macrhybopsis storeriana in western Lake Erie from 1979 through 1987. These data are potentially useful to those studying recovery and restoration of Silver Chub in Lake Erie. These data were collected as part of routine trawl surveys in western Lake Erie. Other data associated with these data can be found in the Great Lakes Research Vessel Operations 1958-2018. (ver. 3.0, April 2019). A drawn map, originally packaged alongside the hard copy data sheets, is included in this data release. This map guides users in identifying specific locations of capture. Due to the legacy nature of these data, location data is estimated based on the points on this map and knowledge of Lake Erie geography.
本数据集收录了1979年至1987年伊利湖西部银突吻鱼(Silver Chub,Macrhybopsis storeriana)的体长、体重、性别及估算繁殖力数据表。该数据集可为研究伊利湖银突吻鱼种群恢复与修复的科研人员提供参考。本数据集的数据采集自伊利湖西部的常规拖网调查项目。与之关联的其他数据集可查阅《1958-2018年五大湖研究船作业数据集》(版本3.0,2019年4月发布)。本次数据发布还附带了原纸质数据表配套的手绘捕捞点位地图。该地图可帮助使用者定位具体的捕捞位点。鉴于本数据集属于历史遗留数据,其点位坐标系基于该地图标注点与伊利湖地理知识估算所得。
