Inshore Survey (Massachusetts) {#mass_inshore_survey}

Description: Biomass time series for aggregate species groups from three inshore bottom trawl surveys conducted throughout the NE US:

• NEAMAP (mab_inshore_survey) from Cape Hatteras to RI

• MA Inshore in MA state waters (mass_inshore_survey)

• ME/NH Inshore in ME and NH state waters (ne_inshore_survey)

Indicator family:

• [X] Megafauna

Introduction to Indicator

Indicators from these inshore surveys are analagous to those produced by the NEFSC trawl survey in the aggregate_biomass indicator dataset

Key Results and Visualizations

Each survey shows trends by aggregate group.

Indicator statistics

Spatial scale: Nearshore regions of the MAB and GOM

Temporal scale: Spring and Fall

Synthesis Theme:

• [X] Multiple System Drivers

# Either from Contributor or ecodata

Implications

Some trends match the NEFSC survey, some dont. This is driven by different species availability to surveys in time and space as well as the surveys sampling different habitats. Nearshore habitats are important to fish and fisheries so we monitor them as as well as trends from the larger EPUs.
