Individual Measurements from trawl surveys of fish and invertebrates in Coastal Alabama, Mississippi, and the Chandeleur Islands, March - December, 2016

Fishes and macroinvertebrates were collected using a 12.8m semi-balloon otter trawl with 4 cm mesh in Spring and Fall of 2016 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.

2016年春、秋两季，研究团队于阿拉巴马州、密西西比州近岸海域及尚德勒尔群岛海域，采用网目规格4厘米、总长12.8米的半囊式翼拖网（semi-balloon otter trawl）采集鱼类与大型无脊椎动物样本。针对每一次拖网作业，均记录了该次拖网采样中选取的部分鱼类及大型无脊椎动物的体长数据与个体生物量。其中，针对各物种适配的体长测量值精确至最接近的毫米，生物量则精确至克。
