Supplement 1. Data for all 295 coho salmon bycatch handled in the study.

File List coho_salmon_raw_data.txt (MD5: 7ee1482980ea9c51cadf1b280e817a5b) Description The file named "coho_salmon_raw_data.txt" is a tab-delimited file that contains raw data from at-capture metadata and measurements, and basic post-release outcomes for all 295 coho salmon caught as bycatch in the Raby et al study. Columns headers are provided. Further description of column definitions: YearFish.No: an arbitrary and sequential fish number identifier, within each study year. Date: Day of the month (all dates in September) Year: Study year TagSite: Refers to the location of capture/release – see Fig. 1 in paper for further details Set: Seine set identifier TotalCatch: Estimated number of fish caught in the set in which that fish was caught FisheryHandlingTime (s): Total number of sections that fish was in the beach seine (see paper for more details) Treatment: Refers to whether a fish was radio-tagged, blood sampled, or simply assessed for RAMP DOA?: Dead on arrival. 1 = fish that was dead when pulled from the net. 0 = alive. StockID: Individual spawning stream to which the fish was DNA-identified RAMP: RAMP score for that individual (see paper for detail on how this was calculated) Revival: 0 if not revived, 1 = revived for 30 min a fish recovery bag (see paper for further detail) ResearchTime: Time from release from the seine (entry into fish tagging bag) to release by the research team, in seconds. WaterTemp: Daily mean river temperature for the day of capture and tagging AirTemp: High local air temperature recorded on the day of tagging Survival: 0 = failed to reach spawning areas based on telemetry tracking, 1 = survived FallBack = 1 if the first receiver detection was downstream of the release site, 0 if otherwise Strayed = 1 if the fish was a successful migrant but assessed as straying to a non-natal spawning stream

文件描述：本文件名为coho_salmon_raw_data.txt的文件为制表符分隔格式文件，收录了Raby等人的研究中作为副渔获物捕获的全部295条银大麻哈鱼（coho salmon）的捕获现场元数据、实测数据以及基础放流后结局数据，文件已预置列标题。
各列详细定义如下：
年度内鱼编号（YearFish.No）：各研究年度内分配的任意连续型鱼只识别标识
捕捞日期（Date）：当月具体日期（所有日期均处于9月）
研究年度（Year）：本次研究的实施年度
标记放流位点（TagSite）：指捕获/放流的具体位置，详细说明参见论文图1
围网作业批次（Set）：围网作业的唯一识别码
总捕获量（TotalCatch）：该鱼所在围网批次的预估总捕获鱼数
捕捞处理时长（秒，FisheryHandlingTime）：该鱼在岸置围网中停留的总时段数（详细说明参见论文）
处理方案（Treatment）：指该鱼是否被施加无线电标记、采血，或仅进行RAMP评估（RAMP）
到岸存活状态（DOA?）：即是否为死体。其中1代表从网中取出时已死亡的个体，0代表存活个体
产卵种群溯源编号（StockID）：通过DNA鉴定确定的该鱼所属的产卵溪流标识
RAMP评分（RAMP）：该个体的RAMP评分，评分计算方式详见论文
复苏状态（Revival）：0代表未完成复苏，1代表在30分钟复苏袋中完成复苏的个体（详细说明参见论文）
研究处理时长（ResearchTime）：从将鱼从围网中取出放入标记袋，到研究团队完成操作后放流的总时长，单位为秒
河流水温（WaterTemp）：捕获及标记当日的日均河流水温
当地最高气温（AirTemp）：标记当日记录的当地最高气温
存活结局（Survival）：0代表通过遥测追踪确认未抵达产卵场，1代表成功抵达产卵场
洄游反向状态（FallBack）：若首个接收器检测记录位于放流位点下游，则记为1，否则记为0
洄游偏离状态（Strayed）：若该鱼为成功洄游个体，但被判定为偏离至非出生地的产卵溪流，则记为1，否则记为0
