Longline trap data collected during R/V Apalachee cruise AP-1503 in the DeSoto Canyon from 2015-03-30 to 2015-04-23

The objectives of this project included using fish traps and demersal longlines to describe and examine differences in species assemblage and relative abundance of demersal fishes in the Gulf of Mexico. This dataset reports the samples collected and associated data from March 30 to April 23, 2015. For some species, biological data such as length and weights are reported. Additional data include the dates, set locations (latitudes, longitudes), depth, water temperature, gear deployed and bait used. These data were collected during the R/V Apalachee cruise AP-1503.本项目的研究目标为，采用捕鱼笼与底延绳钓（demersal longlines）技术，对墨西哥湾内底栖鱼类（demersal fishes）的物种群落组成及相对丰度差异进行描述与分析。本数据集收录了2015年3月30日至4月23日期间采集的样品及配套相关数据；针对部分物种，还收录了其体长、体重等生物学测定数据。补充收录的数据包括采样日期、布放位点（纬度、经度）、水深、水体温度、所用作业渔具及饵料类型。本数据集所有数据均采集自“阿巴拉契号”科研考察船（R/V Apalachee）的AP-1503航次。
