Long-term fish size data for Wisconsin Lakes Department of Natural Resources and North Temperate Lakes LTER 1944 - 2012 (Reformatted to the ecocomDP Design Pattern)

This data package is formatted as an ecocomDP (Ecological Community
Data Pattern). For more information on ecocomDP see
https://github.com/EDIorg/ecocomDP. This Level 1 data package was
derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-ntl/357/2. The
abstract below was extracted from the Level 0 data package and is
included for context: This dataset describes long-term (1944-2012) variations in individual fish total lengths from Wisconsin lakes. The dataset includes information on 1.9 million individual fish, representing 19 species. Data were collected by Wisconsin Department of Natural Resource fisheries biologists as part of routine lake fisheries assessments. Individual survey methodologies varied over space and time and are described in more detail by Rypel, A. et al., 2016. Seventy-Year Retrospective on Size-Structure Changes in the Recreational Fisheries of Wisconsin. Fisheries, 41, pp.230-243.

本数据包采用ecocomDP（生态群落数据模式，Ecological Community Data Pattern）格式进行组织。关于ecocomDP的详细信息，可访问：https://github.com/EDIorg/ecocomDP。
本一级数据包源自如下链接中的零级数据包：https://pasta.lternet.edu/package/metadata/eml/knb-lter-ntl/357/2。
下述摘要提取自该零级数据包，用于提供背景参考：
本数据集记录了1944年至2012年间威斯康星州各湖泊内鱼类个体总长度的长期变化特征，涵盖19个物种的共计190万条鱼类个体数据。该数据由威斯康星州自然资源部渔业生物学家作为常规湖泊渔业评估工作的一部分采集获得。不同调查的方法会随空间与时间存在差异，相关细节可参阅Rypel A. 等人2016年发表的研究论文：《威斯康星州休闲渔业体型结构变化的七十年回顾》，刊载于《渔业》（Fisheries）第41卷，第230-243页，可通过以下链接获取：http://afs.tandfonline.com/doi/abs/10.1080/03632415.2016.1160894
