DOWNLOAD EBOOKSpotted seatrout (Cynoscion nebulosus) receive considerable fishing pressure as the most popular saltwater target species in the north-central Gulf of Mexico. The potential for alternate management strategies, including stock enhancement and reducing discard mortality, to support the sustainability of the stocks and the desires of stakeholders is unknown. The purpose of this study was to provide an objective evaluation of the efficacy of alternate management strategies for spotted seatrout in Louisiana, Mississippi, and Alabama. I used a management strategy evaluation (MSE) to measure the performance of 18 alternate management scenarios relative to control scenarios. Scenarios with a high hatchery input exhibited the highest expected benefit to the stock and fishery in each state; reducing discard mortality had a substantially lesser predicted effect. MSE model results indicated that the expected outcome of alternate management strategies was highly variable by state in the north-central Gulf of Mexico. Characteristics of the stock and fishery in the three states provided information to describe the observed geographic variability in MSE model results. States with a large stock size such as Louisiana exhibited the lowest potential benefit from the management alternatives evaluated. Key fishery characteristics included the proportion of fishing mortality due to discarding, and the minimum length limit imposed by managers. Results from this study provide insights regarding the optimal management of spotted seatrout in the north-central Gulf of Mexico.

DOWNLOAD EBOOKThe United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.

DOWNLOAD EBOOKThe association of juvenile spotted seatrout (Cynoscion nebulosus) and red drum (Sciaenops ocellatus) with Submerged Aquatic Vegetation (SAV) is well documented. However, their association with other estuarine habitats including shallow (non-vegetated) sandy areas is not well understood. The goal of this project was to evaluate habitat use and distribution of juvenile spotted seatrout and red drum along shallow habitats in Pamlico River, North Carolina. The specific objectives were: 1) to evaluate the spatiotemporal patterns of juvenile spotted seatrout and red drum distribution; 2) to determine the effect of habitat type (SAV, sand, and detritus) on growth and mortality; 3) to determine the accuracy and precision in estimating fish age from otoliths with two methods: polishing and oil immersion; and 4) to distinguish how fish community structure (intraspecific and interspecific networks) may affect the presence of juvenile spotted seatrout and red drum distribution in the fish community. Pamlico River was divided into three 21.6-km strata from Fork Point Island westward, to the mouth of the Pungo River. The three areas were identified as West, Central, and East and each contained six fixed stations. Juvenile spotted seatrout and red drum were collected twice a month with an 18-m beach seine from August through November 2009 and 2010. Three substrate samples at each site were also collected once during the second sampling season. All fish were weighed (nearest 0.01 mg), measured (TL, SL in mm). Size (TL) ranged from 30 to 160 mm TL for spotted seatrout and from 15 to 65 mm TL for red drum. The West area of Pamlico River had the highest abundance of juvenile spotted seatrout and the Central had the highest abundance of juvenile red drum. Juvenile spotted seatrout hatch dates were most frequent in June, while juvenile red drum were most frequent during August. Red drum were mostly associated with detritus (52%) compared to sand (20%) or SAV (28%), whereas spotted seatrout were primarily associated with SAV (57%). Furthermore, instantaneous growth of spotted seatrout and red drum did not differ among habitats. Results of this study show how a euryhaline environment and habitat type could potentially influence fish distribution patterns. Results herein will support the development and updating of a fishery management plan for spotted seatrout and red drum in North Carolina.

DOWNLOAD EBOOKThe spotted seatrout is an important species not only for recreational and commercial fisheries, but also as an integral part of many estuarine ecosystems. As one of the few fishes that live its entire life within an estuarine system, the species has tremendous potential as a monitor or sentinel for estuarine conditions. Prepared by the foremost au
