Longline trap data collected during R/V Apalachee cruise AP-1307 in the DeSoto Canyon from 2013-07-18 to 2013-08-04

This dataset reports species caught using longline and trap sets during R/V Apalachee cruise in the DeSoto Canyon from July 18 to August 4, 2013. Species data includes species name, sex, weight, length, and maturity state, if available. It also report if samples were collected from individuals for other analysis, though the results of those analyses are not reported. Information about the longlines set includes bait used, gear, effort, and sea state. Additional files in the dataset report pressure and temperature data collected during longline trapping activities. The overall objectives of this research include using large chevron traps and demersal longlines to describe and examine differences in the species assemblages and relative abundances of demersal fishes associated with the eastern and western walls of DeSoto Canyon and the adjacent continental slope (75-2000 m deep) and collecting specimens and samples (including curation of new species) to aid in resolving phylogenetic uncertainties and understanding life history traits in collected taxa.

本数据集记录了2013年7月18日至8月4日期间，在阿巴拉契号（R/V Apalachee）科考航次中于德索托峡谷（DeSoto Canyon）开展延绳钓与陷阱捕捞作业所捕获的物种。物种数据涵盖物种名称、性别、体重、体长及成熟状态（若可获取相关信息）。数据集同时记录了是否从捕获个体采集了用于其他研究分析的样本，但未公开这些分析的最终结果。延绳钓作业的相关信息包括所用饵料、渔具、捕捞努力量与海况。数据集附带的其他文件记录了延绳钓与陷阱捕捞作业期间采集的压强与温度数据。本研究的总体目标包含两部分：一是采用大型雪佛龙陷阱与底层延绳钓，描述并解析德索托峡谷东西侧壁及相邻大陆坡（水深75~2000米）相关底层鱼类的物种群落组成与相对丰度差异；二是采集标本与样本（包括新物种的标本保藏与整理），以助力解决分类类群的系统发育不确定性，并明晰所采集类群的生活史特征。
