Individual Measurements from trawl surveys of fish and invertebrates in Coastal Alabama, Mississippi, and the Chandeleur Islands, April-July 2015

Fishes and macroinvertebrates were collected using a 12.8m semi-balloon otter trawl with 4 cm mesh in Spring and Fall of 2015 in the coastal waters of Alabama and Mississippi, as well as the Chandeleur Islands. Length measurements and individual biomass of a subset of fish and macroinvertebrates taken in the trawls were recorded for each trawl. Length measurements appropriate for each species were recorded to the nearest millimeter, and biomass was recorded to the gram.

2015年春季与秋季，研究人员使用网目尺寸为4厘米、总长12.8米的半囊式底拖网（semi-balloon otter trawl），在阿拉巴马州、密西西比州近岸海域以及尚德勒尔群岛（Chandeleur Islands）周边水域采集鱼类与大型无脊椎动物样本。针对每一次拖网作业，研究人员均记录了该次拖网采集样本中部分鱼类与大型无脊椎动物的体长数据及个体生物量。其中，针对各物种适配的体长测量标准，将体长精确记录至最接近的毫米值；生物量则以克为单位进行登记。
