The long-term declining trend in landings didn't change.

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.

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.

Although scallop decreases are partially explained by a decreased TAC, analyses suggest that the drop in landings is at least partially due to market disruptions due to the COVID-19 pandemic. However, we do not anticipate the long-term declining trend in landings to change.

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.
