Shifting trophic architecture of marine fisheries in New Zealand: Implications for guiding effective ecosystem‐based management

Summary

Here we analyse fisheries catch data and fisheries independent trawl survey data to resolve changes in community structure, trophic structure and biomass including discards between 1930 and 2019. The data provide an important history of the development of industrialised fishing in New Zealand and important ecological baseline information directly relevant to implementation of ecosystem-based management (EBM).
