Aging data of reef fish collected at natural reefs sites in the northern Gulf of Mexico from 2015-08-30 to 2017-11-03

This dataset contains aging data of reef fish collected at the natural reef sites in the northern Gulf of Mexico from August 2015 to December 2017. Sagittal otoliths were sampled from reef fishes and sectioned and aged depending on fish size. Opaque zones were counted and the margin of the otolith was indicated as being either Opaque (“O”) or Translucent (“T”).本数据集涵盖2015年8月至2017年12月期间，在墨西哥湾北部天然礁场采集的礁栖鱼类的年龄鉴定数据。研究人员从礁栖鱼类体内采集矢耳石（Sagittal otoliths），并根据鱼类个体体型对耳石进行切片与年龄鉴定。研究人员会计数耳石的不透明生长轮，并将耳石边缘标记为不透明（以"O"标识）或半透明（以"T"标识）。
