Notable 2023 events and conditions
Indicator: Commercial landings
Indicators: Recreational harvest
Multiple potential drivers of landings changes: ecosystem and stock production, management actions, market conditions, and environmental change.
The long-term declining trend in landings didn't change.
Indicator: Stock status
Most stocks have good status. Spiny dogfish B and F status have improved. Mackerel F status has improved, but B is still below the threshold. Summer flounder F exceeds the limit.
Indicators: Total ABC or ACL, and Realized catch relative to management target
Few managed species have binding limits; Management less likely playing a role
Stock status affects catch limits established by the Council, which in turn may affect landings trends. Summed across all MAFMC managed species, total Acceptable Biological Catch or Annual Catch Limits (ABC or ACL) have been relatively stable 2012-2020 (top). With the addition of blueline tilefish management in 2017, an additional ABC and ACL contribute to the total 2017-2020. Discounting blueline tilefish, the recent total ABC or ACL is lower relative to 2012-2013, with much of that decrease due to declining Atlantic mackerel ABC.
Nevertheless, the percentage caught for each stock’s ABC/ACL suggests that these catch limits are not generally constraining as most species are well below the 1/1 ratio (bottom). Therefore, stock status and associated management constraints are unlikely to be driving decreased landings for the majority of species.
Biomass does not appear to drive landings trends
Key: Black = NEFSC survey; Red = NEAMAP survey New species categories, more southern species in Benthivores
Declining managed benthos, aggregate planktivores
Markets and availability (benthos), fishery consolidation (planktivores)
Monitor:
Stock status is above the minimum threshold for all but two stocks, and aggregate biomass trends appear stable, so the decline in managed commercial seafood landings is most likely driven by market dynamics affecting the landings of surfclams and ocean quahogs, as landings have been below quotas for these species. In addition, regional availability of scallops has contributed to the decline of benthos landings not managed by the MAFMC, with some of the most productive grounds currently closed through rotational management. The long term decline in total planktivore landings is largely driven by Atlantic menhaden fishery dynamics, including a consolidation of processors leading to reduced fishing capacity between the 1990s and mid-2000s.
Recreational drivers differ: shark fishery management, possibly survey methodology
Climate change also seems to be shifting the distribution of surfclams and ocean quahogs, resulting in areas with overlapping distributions and increased mixed landings. Given the regulations governing mixed landings, this could become problematic in the future and is currently being evaluated by the Council.
Indicator: Commercial Revenue
Recent change driven by benthos
Monitor changes in climate and landings drivers:
Indicator: Bennet--price and volume indices
baseline year for indicator has changed from previous reports Although the Mid-Atlantic region shows declining revenue trends since 2016, inflation-adjusted revenue from harvested species was still greater than 1982 levels until 2022. In a similar manner to seafood landings, the results here are driven in large part by market dynamics affecting the landings of surfclams and ocean quahogs, as landings have been below quotas for these species, as well as lower quotas for Atlantic scallops. The declining Benthos category since 2012 may be partially caused by decreases in surfclam and ocean quahogs in the southern part of their range as harvest have shifted northward. 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:
Net revenue calculable for ~ 1/2 of the revenue generated within the Greater Atlantic Region. Trends between the total gross revenue and gross revenue for which we can estimate costs are different. Net revenue looks to be just a scaled gross revenue metric: similar trend, different magnitude.
Indicators: Recreational effort and fleet diversity
Implications
Adding 2022 data, recreational effort (angler trips) again has a long term increase.
The increasing long term trend changed the risk category for the RecValue element back to low-moderate (previously ranked low risk).
New risk element: Decline in recreational fleet diversity suggests a potentially reduced range of opportunities.
Driven by party/charter contraction and a shift toward shore based angling.
Changes in recreational fleet diversity can be considered when managers seek options to maintain recreational opportunities. Shore anglers will have access to different species than vessel-based anglers, and when the same species, typically smaller fish. 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.
Fishery Indicators: Commercial fleet count, fleet diversity
Most recent fleet counts at low range of series
Fishery Indicators: commercial species revenue diversity, recreational species catch diversity
Most recent near series low value. Covid role?
Ecological Indicators: zooplankton and larval fish diversity (not updated)
Ecological Indicator: expected number of species, NEFSC bottom trawl survey
Implications:
While larval and adult fish diversity indices are stable, a few warm-southern larval species are becoming more dominant. Increasing zooplankton diversity is driven by declining dominance of an important species, which warrants continued monitoring.
Indicators: Environmental justice vulnerability, commercial fishery engagement and reliance
Implications: Highlighted communities may be vulnerable to changes in fishing patterns due to regulations and/or climate change. When also experiencing environmental justice issues, they may have lower ability to successfully respond to change.
These plots provide a snapshot of the presence of environmental justice issues in the most highly engaged and most highly reliant commercial and recreational fishing communities in the Mid-Atlantic. These communities may be vulnerable to changes in fishing patterns due to regulations and/or climate change. When any of these communities are also experiencing social vulnerability including environmental justice issues, they may have lower ability to successfully respond to change.
Indicators: Environmental justice vulnerability, recreational fishery engagement and reliance
Implications: Highlighted communities may be vulnerable to changes in fishing patterns due to regulations and/or climate change. When also experiencing environmental justice issues, they may have lower ability to successfully respond to change.
Indicators: Harbor porpoise and gray seal bycatch
Implications:
Currently meeting objectives for harbor porpoise and gray seals
Risk element: TechInteract, evaluated by species and sector: 14 low, 7 low-mod, 2 mod-high risk, 1 improved
The downward trend in harbor porpoise bycatch can also be due to a decrease in harbor porpoise abundance in US waters, reducing their overlap with fisheries, and a decrease in gillnet effort.
The increasing trend in gray seal bycatch may be related to an increase in the gray seal population (U.S. pup counts).
Indicators: North Atlantic right whale population, calf counts
Implications:
Signs the adult population stabilized 2020-2022
Population drivers for North Atlantic Right Whales (NARW) include combined fishery interactions/ship strikes, distribution shifts, and copepod availability.
Additional potential stressors include offshore wind development, which overlaps with important habitat areas used year-round by right whales, including mother and calf migration corridors and foraging habitat.
Unusual mortality events continue for 3 large whale species. 1 UME is pending closure for pinnipeds.
Indicators: Fish distribution shifts
Cetacean distribution shifts
Drivers: Forage shifts, temperature increase
Drivers: changing ocean habitat
Cold pool temperature and spatial extent
Future considerations
Adapting management to changing stock distributions and dynamic ocean processes will require continued monitoring of populations in space and evaluating management measures against a range of possible future spatial distributions.
Indicators: spawning timing, migration change
Drivers
Cold pool seasonal persistence
Future considerations
Management actions that rely on effective alignment of fisheries availability and biological processes should continue to evaluate whether prior assumptions on seasonal timings still hold.
New indicators should be developed to monitor timing shifts for stocks.
Indicators: fish productivity and condition
Drivers: Forage Quality and Abundance
Drivers: Low tropic levels
Drivers: Environmental
2023 Thermal habitat area by depth
OA in shellfish habitat
Drivers: Predation
Seals increasing, sharks stable, 50% of HMS populations above target
Future considerations
Indicators: fishery and community specific revenue in lease areas
Council request: which New England ports have significant reliance on Mid-Atlantic managed species?
Implications:
Evaluating the impacts to scientific surveys has begun.
Record low hypoxia in Chesapeake Bay since 1995, relatively cool summer with high salinity.
Sea scallop recruitment detected Spring 2022, gone in Spring 2023
Days in 2022 at or above scallop stress temperature 17-19 C →
In Chesapeake Bay, hypoxia conditions were the lowest on record (since 1995), creating more suitable habitat for multiple fin fish and benthic species. Cooler Chesapeake Bay water temperatures paired with low hypoxia in the summer suggest conditions that season were favorable for striped bass. Cooler summer temperatures also support juvenile summer flounder growth. However, warmer winter and spring water temperatures in the Chesapeake Bay, along with other environmental factors (such as low flow), may have played a role in low production of juvenile striped bass in 2023. Higher-than-average salinity across the Bay was likely driven by low precipitation and increased the area of available habitat for species such as croaker, spot, menhaden, and red drum, while restricting habitat area for invasive blue catfish.
Intermittent warm waters like this can be threats to temperature sensitive species, especially species at the southern end of their range or are not mobile (e.g. scallops), while also providing suitable habitat for more southern species.
