Biological Indicators and Mercury Concentrations in Smallmouth Bass

Biological indicators including morphometric (length, weight), age, sex and health indicators including organismal (health assessment index, condition factor), organ (hepatosomatic index, gonadosomatic index), cellular (intersex, parasite density, macrophage aggregate density), subcellular (plasma vitellogenin, estradiol, testosterone, 11-keto testosterone) and molecular (hepatic transcript abundance) were measured in smallmouth bass from tributaries in the Chesapeake Bay watershed. Total mercury was measured in these fish and correlations between mercury and biological indicators were assessed.

本数据集针对切萨皮克湾流域支流中的小口黑鲈，测定了多项生物指标：包括形态测量学（morphometric）指标（体长、体重）、年龄与性别信息，以及多维度健康指标——涵盖个体水平（organismal）的健康评估指数、条件因子，器官水平（organ）的肝体指数（hepatosomatic index）、性腺指数（gonadosomatic index），细胞水平（cellular）的雌雄同体现象、寄生虫密度、巨噬细胞聚集密度，亚细胞水平（subcellular）的血浆卵黄蛋白原（plasma vitellogenin）、雌二醇（estradiol）、睾酮（testosterone）、11-酮睾酮（11-keto testosterone），以及分子水平（molecular）的肝脏转录本丰度（hepatic transcript abundance）。同时对受试小口黑鲈体内的总汞含量进行了测定，并评估了总汞水平与各项生物指标之间的相关性。
