Matrix of functional traits of species sampled in the annual survey of the estuary and the northern Gulf of St. Lawrence

This dataset contains functional traits for fish and invertebrate taxa sampled in the annual ecosystem bottom trawl survey in the Estuary and northern Gulf of St. Lawrence. The purpose of this functional trait matrix is to contribute to the development and monitoring of community indicators to support the implementation of ecosystem-based management. In a context of climate change, this information will better inform and facilitate sustainable management processes and the adaptation of human activities that directly depend on the state of marine species and communities. The functional trait matrix was established based on a literature review, the knowledge of experts who have worked for over twenty years to develop knowledge on marine species in the St. Lawrence, and empirical data from the ecosystem bottom trawl survey conducted by DFO Quebec Region in the Estuary and Northern Gulf of St. Lawrence (NGSL) since 1990. It includes a total of 103 fish taxa and 178 invertebrate taxa captured in the survey. Each trait is compiled for all or a subset of the selected taxa. The trait matrix includes a grouping of taxa into trophic guilds based on fuzzy coding, a categorization of taxa…
