Metal (Hg, As, Se), lipid and nitrogen levels within fish muscular system in two fish species (Striped Bass from aquaculture and wild Northern Pike)

Distribution of methylmercury, selenium and arsenic within fish muscular system of Striped Bass and Northern Pike. Distribution of metal(loid)s was assessed according to muscle zone, muscle depth and muscle type. Methylmercury and selenium were positively linked to the protein content, while arsenic was positively correlated to the lipid content. In individual Striped Bass muscle tissues, metals varied on average by 2.2-fold, in contrast of the pike with 1.4-fold. The heterogeneous distribution of metal(loid)s in the Striped Bass muscle seems to came from the presence of the red muscle at its lateral line. In Pike flesh, red muscle were negligible.

本数据集聚焦条纹石鮨（Striped Bass）与白斑狗鱼（Northern Pike）肌肉系统内甲基汞、硒及砷的分布特征。研究依据肌肉区域、肌肉深度及肌肉类型对金属及类金属（metal(loid)s）的分布进行了评估。甲基汞与硒的含量与蛋白质含量呈显著正相关，而砷的含量则与脂质含量呈正相关。在单尾条纹石鮨的肌肉组织中，金属元素的平均变异倍数为2.2倍；与之相比，白斑狗鱼的金属元素平均变异倍数仅为1.4倍。条纹石鮨肌肉中金属及类金属的不均匀分布，似乎与其侧线处存在红肌密切相关。白斑狗鱼的肌肉组织中红肌占比极低，可忽略不计。(10.5281/zenodo.4717607)
