Relative abundance and body size of fishes observed by Alaskan fishers from the 1980s to 2010s

The data are relative abundance and body size of seven fish species reported by 98 subsistence and charter fishers from Southeast and Southcentral Alaska. Data were collected through semi-structured interviews with fishers in 2014-2016. Fishers were asked to indicate relative abundance for each species on a Likert scale, from 1 (very low) to 7 (very high), for each decade in which they had fished. They also provided the typical size (or size range) of fish caught for each species and decade. The data are contained in a single file titled: “LEK_abundance_size.csv”

本数据集包含来自阿拉斯加东南部及中南部的98名自给自足渔民与特许捕捞渔民报告的7种鱼类的相对丰度与体尺数据。数据于2014至2016年间通过对渔民的半结构化访谈采集得到。受访渔民需根据自身从事捕捞的每个十年时段，为各鱼种按李克特量表（Likert scale）标注相对丰度，量表取值范围为1（极低）至7（极高）。同时，渔民还需提供对应十年时段内捕捞的各鱼种的典型体尺（或体尺范围）。所有数据均收录于名为"LEK_abundance_size.csv"的单个文件中。
