Fish length- and fishing ground depth-driven variation of diet drives Anisakis levels in a zooplankton-feeding fish

This dataset gathers trophic and parasitic information on European jack mackerel (Trachurus trachurus) collected in the English Channel during the CAMANOC survey in 2014. Each individual fish is described by size, trophic status (δ13C, δ15N, C/N and calculate trophic level), dietary items from stomach content, and levels of infestation by the parasite nematode Anisakis in 6 tissues (abdominal cavity, liver, gonads, stomach, left and right muscle).

本数据集汇集了2014年英吉利海峡CAMANOC科考中采集的欧洲竹荚鱼（Trachurus trachurus）的营养与寄生生物相关信息。每尾采样个体均记录有以下信息：体型大小、营养状态指标（碳稳定同位素δ¹³C、氮稳定同位素δ¹⁵N、碳氮比C/N及计算得到的营养级）、胃含物中的食物组成，以及6种组织（腹腔、肝脏、性腺、胃、左侧肌肉、右侧肌肉）内寄生线虫异尖线虫（Anisakis）的侵染水平。
