The Impact

Abstract Anadromous populations of striped bass occur along the Atlantic coast of the US from Maine to North Carolina. Recruitment overfishing and declining water quality led to substantial reductions in striped bass abundance during the 1970s and 1980s. Cooperative interstate fishery management of striped bass began in 1981, with the development of a fishery management plan by the Atlantic States Marine Fisheries Commission, an organization of Atlantic coastal states. Effective fishery management and additional research and monitoring contributed to a tenfold increase in abundance of striped bass stocks by the late 1990s. This dramatic increase resulted in increased predation on a variety of anadromous fish species including American shad, blueback herring, and alewives. Predation by striped bass on Atlantic salmon smolts in North America has been documented, but the impact of this predation has not been quantified. Moderate to strong correlations were found between estimates of striped bass abundance and the return of Atlantic salmon to three of the four major New England salmon rivers. Further research is required to quantify the proportion of smolt production consumed by striped bass, particularly for salmon populations listed as endangered under the US Endangered Species Act.

Abstract Haring, P., and Maguire, J-J. 2008. The monkfish fishery and its management in the northeastern USA. – ICES Journal of Marine Science, 65: 1370–1379. The domestic monkfish (Lophius americanus) fishery off the northeastern USA is described, along with the management response to the expansion of the fishery and the challenges posed to the management and scientific processes. The US fishery was virtually non-existent in the early 1980s, but it expanded rapidly over the next decade to the point that a management plan became necessary to regulate harvesting. By law, US fishery management plans must include measurable biological reference points based on maximum sustainable yield or a proxy; management plans must stop overfishing and rebuild overfished stocks. For monkfish, the limited biological and historical fisheries information presented significant challenges to science and management and resulted in the adoption of innovative approaches to comply with the law.

We examined the consequences of ignoring the distinction between measurement error and natural variability in an assessment of risk to the Hudson River stock of striped bass posed by entrainment at the Bowline Point, Indian Point, and Roseton power plants. Risk was defined as the probability that recruitment of age-1+ striped bass would decline by 80% or more, relative to the equilibrium value, at least once during the time periods examined (1, 5, 10, and 15 years). Measurement error, estimated using two abundance indices from independent beach seine surveys conducted on the Hudson River, accounted for 50% of the variability in one index and 56% of the variability in the other. If a measurement error of 50% was ignored and all of the variability in abundance was attributed to natural causes, the risk that recruitment of age-1+ striped bass would decline by 80% or more after 15 years was 0.308 at the current level of entrainment mortality (11%). However, the risk decreased almost tenfold (0.032) if a measurement error of 50% was considered. The change in risk attributable to decreasing the entrainment mortality rate from 11 to 0% was very small (0.009) and similar in magnitude to the change in risk associated with an action proposed in Amendment #5 to the Interstate Fishery Management Plan for Atlantic striped bass (0.006)— an increase in the instantaneous fishing mortality rate from 0.33 to 0.4. The proposed increase in fishing mortality was not considered an adverse environmental impact, which suggests that potentially costly efforts to reduce entrainment mortality on the Hudson River stock of striped bass are not warranted.

Migratory Pattern

Northern gannets, Sula bassanus, and possibly other seabird species nesting on Funk Island off northeastern Newfoundland preyed on postsmolt Atlantic salmon, Salmo salar. Salmon comprised less than 1% of 2928 regurgitated food samples collected from gannets at the colony. Ten smolt tags were recovered in and near the gannetry during August or September in 1984 through 1986. The tags were from smolts released 3–4 mo earlier in the Penobscot River (Maine) (n = 7) and one each from the Saint John River (New Brunswick) and the Lower Clyde and LaHave rivers (Nova Scotia). These recoveries provide evidence that postsmolt Atlantic salmon from rivers in New England, the Bay of Fundy, and the Atlantic coast of Nova Scotia migrate off eastern Newfoundland This migratory pattern contrasts with that of postsmolts from the Gulf of St. Lawrence, which tend to move northwards along Newfoundland's west coast and through the Strait of Belle Isle.

The striped bass (Morone saxatilis) is an economically and ecologically valuable finfish species that inhabits nearshore and estuarine waters of many states along the US Atlantic coast. Chesapeake Bay provides extensive nursery and foraging habitats for striped bass, yet fish in the bay exhibit high prevalence of disease caused by bacteria in the genus Mycobacterium. Detection of population-level impacts associated with mycobacteriosis has been difficult because the disease is chronic and synoptic biological and disease data have been limited. Here, we present modeling analyses of growth data for disease-positive and -negative striped bass in Chesapeake Bay. Three growth relationships were considered, and for each, a single model was parameterized to include several covariates, most notably disease status and severity. Our results indicate that disease-positive and -negative fish have differing growth patterns and that the estimated asymptotic sizes of disease-positive fish are considerably lower than those of disease-negative fish. Compromised growth along with documentation that striped bass in Chesapeake Bay are experiencing disease-associated mortality suggests that disease may be reducing the productivity of this species.

<i>Abstract</i>.—The Striped Bass <i>Morone saxatilis</i> is an extremely important commercial and recreational species with a coastal migratory stock in the United States referred to as “Atlantic Striped Bass” managed by the Atlantic States Marine Fisheries Commission (ASMFC). Atlantic Striped Bass has four major contributing stocks, including the Chesapeake Bay, which comprises 70–90%, and the Hudson River, the Delaware River, and the Albemarle Sound/Roanoke River (A/R). The collapse of Atlantic Striped Bass in the late 1970s precipitated federal funding and legislation like the Emergency Striped Bass Study for research on causative factors of the decline and potential management recommendations. The 1981 ASMFC Interstate Fishery Management Plan (ISFMP) for Atlantic Striped Bass was nonmandatory and mostly ineffective until the 1984 Atlantic Striped Bass Conservation Act provided regulatory authorities to the ASMFC and the federal government to close fisheries in states out of compliance with ISFMPs. Restrictions and moratoria on harvest imposed in several states reduced mortality, and under favorable environmental conditions and given Striped Bass life history, multiple years of good recruitment occurred. This allowed target thresholds for female spawning stock biomass to be achieved and the ASMFC to declare recoveries of Atlantic Striped Bass stocks from 1995 to 1998. Regulation of river flows was particularly important for the A/R stock recovery, and this stock is presented as a case study. During the 20+ years following recovery, long-term monitoring by states in support of adaptive management was primarily supported by the stable, nonappropriated funding of the Sport Fish Restoration Act. Monitoring includes spawning stock characterization and biomass estimation, juvenile abundance surveys, cooperative coastwide tagging, and harvest data collection. Future issues facing the recovered Atlantic Striped Bass include interspecies effects of relatively high abundance, management of stocks separately instead of as a single coastal stock, and ecosystem-based fisheries management. Key lessons learned in the Atlantic Striped Bass recovery are that high societal value of the species provided the political impetus to create and fund the recovery program, coordination of management and enforcement efforts among all jurisdictions was essential for this migratory species, and fully funded long-term monitoring programs are critical to adaptive population management.

The Impact

Impacts from proposed conservation plans in the US Atlantic menhaden industry are examined in this paper. The regulations have been proposed because of concerns that fishing pressure has been too intense on juvenile menhaden. The impacts are examined by the use of a bioeconomic model in which a time-dynamic and geography-specific framework is employed. The results indicate that a shorter fishing season would redistribute the existing pattern of catches and income. The whole industry would experience a net gain but the gainers and losers are clearly delineated spatially and temporally.

Abstract In 1979, we gathered clutch-size and reproductive-success data on Black-crowned Night-Herons (Nycticorax nycticorax) nesting in three New England and two North Carolina colonies. In 1975, we gathered similar data from one of the New England and one of the North Carolina colonies. Latitudinal differences in clutch initiation were not evident. Mean clutch size was larger in the New England than in the North Carolina colonies. Mean clutch size was smaller in late nests from one New England colony studied in both years and another New England colony studied in 1979; seasonal trends in clutch size for other colonies were not found. In 1979, nest success was greater in two New England colonies than in one North Carolina colony. Within-season differences in nest success occurred but were inconsistent among colonies. In the four instances where statistical comparisons could be made, larger clutches were more successful than smaller ones in two colonies; large and small clutches had similar success in two other colonies. One egg was collected from each of several nests in each colony in 1979 for organochlorine contaminant analysis, and the fate of the remaining eggs was recorded. Concentrations of DDE and PCBs did not differ with clutch size; concentrations of PCBs were lower, however, in eggs laid late in the season. Although the data suggest an effect of DDE on hatching success in the northern more contaminated colonies, the impact of environmental contaminants on overall reproductive success appears to be minimal.
