The data we provide here have been assembled to categorise fish into feeding guilds and determine change in populations of fish with different feeding traits relevant to food web status assessment advocated by OSPAR. We provide four datasets: the first is a csv file titled ‘stomach data observations’ contains observations from fish stomach contents of individual prey weight, prey functional group (i.e., zooplankton, benthos, fish, nekton and other), predator taxonomy, predator size, and the region and year the samples were collected (Table 1; see Column_headers_readme.txt); the second is a csv file titled ‘modelled stomach data’ provides predictions from a linear mixed effects model of individual prey weight based on those stomach contents observations, alongside modelled estimates of prey counts and biomass which enable the full collation of stomach contents information to be used in our feeding guild classification (Table 2; feeding guilds are predatory categories assigned using cluster analysis on stomach ...
