Abundance and biomass of fish species collected during the day from 1979 to 2000 off the coast of the southeastern United States (Cape Fear, NC to Cape Canaveral, FL). The short bottom longline consists of 25.6 m of 6.4-mm treated solid braid Dacron groundline. 20 gangions (#5 or #7 hooks) are placed 1.2 m apart on the groundline, which is attached to polypropylene line and buoyed to the surface with polyball buoy and a trailer Hi-Flyer buoy.
本数据集记录了1979年至2000年日间于美国东南部沿海（北卡罗来纳州费尔角至佛罗里达州卡纳维拉尔角）采集的鱼类物种丰度与生物量。所用短型底延绳钓采用长度25.6米、直径6.4毫米的经处理实心编织达克纶（Dacron）底纲；底纲上以1.2米间距布置20组支绳（搭配5号或7号鱼钩），该底纲连接聚丙烯绳，并通过聚球浮标（polyball buoy）与牵引式Hi-Flyer浮标将钓具浮升至海面。
