Black drum (Pogonias cromis) can be found in nearshore waters along the Atlantic coast from the Gulf of Maine to Florida and as far south as Argentina. Atlantic coast black drum migrate inshore to the north in the spring, and to the south in the fall. Fish can reach over 46", 120 pounds and 60 years of age. They grow rapidly until the age of 15, at which time growth slows.
Spawning occurs during the winter and early spring, occurring earlier in the southern areas (November - April) and later in the northern areas (April - June). An average-sized female (13.4 pounds) may spawn 32 million eggs each year. Recruitment appears to be sporadic, with infrequent large events.
Black drum are primarily bottom feeders. Young black drum feed on small fish and invertebrates, such as copepods, annelids, and amphipods. The eggs and larvae of this species were shown to be subject to high predation. As juveniles, they are prey to a wide range of estuarine fish species, such as spotted seatrout and crevalle jack.
With sizes reaching over 46 inches in length and 120 pounds in weight, black drum are drawing increasing interest from recreational anglers. While recreational landings in 2016 were similar to recent years at about 1.3 million pounds, landed fish constituted only 27% of all black drum caught by the fishery. The other 73% of recreationally caught fish were released alive, making 2016 the third highest year for releases in number of fish and second highest in percent released. Outside of a large peak in 2008, recreational and commercial landings have remained fairly stable since 2000, with recreational landings typically being 5-6 times those of commercial (by weight). The commercial fishery landed about 225,000 pounds in 2016. Florida and North Carolina fisheries comprised the majority of total (commercial and recreational) harvest and recreational live releases in 2016. In recent years, gillnets and pound nets have been the primary gear used.
The first coastwide benchmark stock assessment for black drum was performed in 2014 and approved for management use in 2015. Based onassessment results, black drum is not overfished and not experiencing overfishing. The median biomass is estimated to be declining slowly, though it is still estimated to be well above that necessary to produce maximum sustainable yield.
Black drum are a data-poor species. Their rarity and complex migratory patterns lead to highly variable levels of encounter in state surveys and fisheries. Further, limited size composition data has been collected, making the use of age-structured models unreliable. For these reasons, data-poor, catch-based modeling methods were used for the assessment. These models estimate reference points based on historical catch data and life history information.
In 2013, the Commission adopted the Interstate Fishery Management Plan (FMP) for Black Drum, which requires all states to implement a maximum possession limit and a minimum size limit of no less than 14 inches in addition to maintaining their previous regulations. Further, the FMP establishes a management framework to address future concerns or changes in the fishery or population.
The FMP also includes a management framework to adaptively respond to future concerns or changes in the fishery or population. Concern about the increase in harvest by both recreational and commercial fishermen in recent years was alleviated by the findings of the 2015 stock assessment. Given the assessment findings, the Board chose to not make any additional changes to the management program at that time.
In March 2017, a report on Sciaenid Fish Habitat was released including information on habitat for several species, including black drum, during all stages of their lives, their associated Essential Fish Habitats and Habitat Areas of Particular Concern, threats and uncertainties to their habitats, and recommendations for habitat management and research. This report is meant to be a resource when amending FMPs in the future for these species.
The Board approved Addendum I to the Black Drum FMP in May 2018. The Addendum allows Maryland to reopen its black drum commercial fishery in the Chesapeake Bay with a daily vessel limit of up to 10 fish and a 28-inch minimum size. Over the next year, Maryland will develop a management program for the commercial fishery with implementation by April 1, 2019.
