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).
