Revenue earned by harvesting resources is a function of both the quantity landed of each species and the prices paid for landings. Therefore, total revenue patterns can be driven by harvest levels, the mix of species landed, price changes, or a combination of these. The [Bennet Indicator](https://noaa-edab.github.io/catalog/bennet.html) (BI) decomposes revenue change into two parts, one driven by changing quantities (volumes), and a second driven by changing prices. All changes are in relation to a base year (1982). The 1982 base year was selected because that is the first year the relevant data is available and it allows for an extended period of time to evaluate market trends and dynamics. The BI results demonstrate that relatively high revenues in 2014-2016 were equally due to higher landings and prices (Fig. \ref{fig:bennet}). In more recent years, both landings and prices have been closer to values from the reference year (1982). A low year for prices in 2024, coupled with low volumes landed, led to low revenue. Recent lower than average revenues are partially due to declining prices of benthivores. Benthos prices increased from 2023, but overall benthos revenue remained low due to low volumes landed (Fig. \ref{fig:bennet-all}).

This year, we present new indicators of profitability: indices of cost, revenue, and profit based on trips catching federally-managed species. In this index, costs pertain to trip costs, excluding labor, estimated for all federal trips in the region using methods described in Werner et al. (2020). The profit indicator is net-revenue, determined as the difference between trip revenue and trip costs. Trips were spatially allocated to compile regional indices. Indices are presented as values relative to 2000, the first year in the dataset. In the Mid-Atlantic, costs have fluctuated, but overall remain near the time series mean, despite some high costs in 2022, 2014 and 2008. Revenue, however, has declined steadily since 2019 and is driving an overall decline in profits (Fig. \ref{fig:comdat-profit}).

For ports combined across Mid-Atlantic states, [total climate vulnerability](https://noaa-edab.github.io/catalog/community_climate_vulnerability.html) of revenue ranged from high to very high from 2000-2021, with no long-term trend.

Although the Mid-Atlantic region shows declining revenue since 2016, inflation-adjusted revenue from harvested species was still greater than 1982 levels until the past two years (Fig. \ref{fig:bennet}). However, revenue from MAFMC-managed species has been below 2000 levels in several of the past 24 years (Fig. \ref{fig:comdat-profit}). The BI demonstrates that this decline is driven by lower volumes and no inverse price effects to offset the decreases in volume. Declines in landings of surfclams and ocean quahogs since 2012 are a result of decreased landings per unit effort over the same period, which may reflect changes in surfclam and quahog aggregation or distribution patterns. Changes in other indicators, particularly those driving landings and those related to climate change, require monitoring as they may become important drivers of revenue in the future; for example:

In the GB region, revenues have been consistently lower than the 1982 baseline throughout the time series. The changes in total revenue in GB was primarily driven by volumes prior to 2010 rather than by prices (Fig.\ref{fig:bennet-ne}).In more recent years, prices have played a larger role in revenue upticks (such as in 2020), but the overall lower than baseline landings have caused a decreasing revenue in the past three years.

In the GOM, revenues have been above the 1982 baseline in all but three years, with the increase being driven more by relatively higher prices rather than landings. Breaking down the GB revenue by guild (Fig. \ref{fig:bennet-all-ne}), both the volume and price trend have been largely driven by benthivores (lobster) and benthos (scallops, quahogs and surfclams). In the GOM region, increased prices for benthivores (lobster) drove the year-over-year increases in overall prices. Benthivores also had a large influence on the overall volume indicator in the GOM.

In the GOM, the profit index closely follows the same trends as the revenue index with the exception of 2010 - 2013 where low costs created a surge in the profit index. In 2023, the GOM profit index dropped to its third lowest point in the time series due to both high costs and below average revenues. For trips in GB, the profit index is similarly low due to high costs, but a stronger cyclical cycle of revenue is present due, in part, to rotational scallop management.

While the overall number of recreational trips in the MAB is above the long-term average, the continuing decline in recreational fleet effort diversity suggests, at least in part, changes in angler behavior. Future study is required to determine whether and to what extent the range and availability of recreational fishing options may drive these changes as well.

The downward effort diversity trend is driven by party/charter contraction (down from 2.2% in 2021 to 1.3% of trips in 2023), and a shift toward shorebased angling, which currently makes up 60% of all angler trips. Private boat effort has remained relatively stable compared to 2022 values.

A contraction of party/charter trips (dropping from 2.2% of trips in 2021 to 1.3% in 2023) is the primary driver of the downward effort diversity trend, alongside a shift toward shorebased angling, which now makes up 60% of trips. Private boat effort has remained consistent to 2022 values.

Managers should consider the differing species and fish sizes for shore-based and vessel-based anglers. Some species use inshore regions as nursery grounds while other species only come inshore as adults. Many states have developed shore-based regulations where the minimum size is lower than in other areas and sectors to maintain opportunities in the shore angling sector. The MAFMC is currently considering recreational sector separation which might establish different options for managing the for-hire sector from other modes.

Shore anglers will have access to different species than vessel-based anglers, and when the same species is accessible both from shore and from a vessel, fish size differs by location, with some species using inshore regions as nursery grounds while other species only come inshore as adults.
