Introduction to Indicator

Feeding guilds are groups of species that feed similarly. At the ecosystem level, the food web is likely stable if overall biomass of feeding groups is stable over time, even if populations of species within the groups may be changing.

We defined feeding guilds for fish and invertebrates captured by bottom trawl surveys using diet similarity, either from diet analysis or from literature [@garrison_dietary_2000; @smith_trophic_2010], and see NEFSC food habits online

Key Results and Visualizations

Each management body (MAFMC, NEFSC, State etc) has its managed species associated with different feeding guilds. This data set shows which managed species for each management body are in which guilds.

Implications

We changed species groupings in response to comments over the years. The table shows feeding guilds used in the 2024 report.
