Commercial fishermen have harvested black drum in Louisiana waters for more than a century. Historically, black drum was harvested commercially as bycatch in other fisheries and secondary to its more popular cousin, the red drum (Sciaenops ocellatus). However, as commercial harvests for red drum were prohibited in federal and most state waters (including Louisiana’s) in the late 1980s, markets for black drum grew and the commercial fishery rapidly expanded. Recent commercial harvests of black drum have averaged nearly 3.9 million pounds per year with a dockside value of more than $3.7 million. Black BLACK DRUM (POGONIAS CROMIS). drum are typically a secondary target for recreational fishermen in Louisiana but increased slightly in popularity beginning in the 1980s as more restrictive regulations were placed on more popular primary target species such as red drum and spotted seatrout (Cynoscion nebulosus). As Louisiana’s black drum fisheries developed, managers implemented a number of measures to prevent overharvesting and maintain the black drum population at sustainable levels. Biologists regularly monitor and assess the condition of this valuable resource to ensure these measures are effective and to inform future management decisions, all in an effort to protect the viability of the black drum resource for future generations. This fishery management plan creates a centralized document that summarizes current information about the biology and status of Louisiana black drum, Louisiana’s commercial and recreational fisheries for black drum, effects of Louisiana’s black drum fisheries on the ecosystem, and environmental influences on Louisiana’s black drum resource. In addition, this plan describes management approaches within the state and regional framework, defines long-term management goals and objectives, identifies management issues, recommends options to address these issues, and outlines future research and data needs. 7 Introduction Definition of Management Unit The management unit includes black drum and its fisheries in coastal and estuarine waters of Louisiana. Management Authority and Process The Louisiana Legislature (Legislature), Louisiana Wildlife and Fisheries Commission (Commission), and Louisiana Department of Wildlife and Fisheries (LDWF) are responsible for managing black drum fisheries in Louisiana’s state waters, which include inland waters and extend seaward from the shoreline to 3 nautical miles. Louisiana Revised Statutes (LA R.S.) Title 56 provide for the preparation and implementation of fishery management plans that will prevent overfishing and achieve and maintain plentiful fish populations to ensure, on a continuing basis, the optimum yield from each fishery. Louisiana’s fishery management plans are developed according to applicable principles and standards of the Food and Agriculture Organization of the United Nations’ (FAO) Code of Conduct for Responsible Fisheries. Responsible fisheries management requires an ongoing process of continual improvement, with active monitoring of fisheries resources and fisheries and timely response to any observed changes. Fishery management plans are flexible and can be

    SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES BY KYLE E. LUTH A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADAUTE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology May 2016 Winston-Salem, North Carolina Approved By: Gerald W. Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips.

  • Parasites of Coral Reef Fish: How Much Do We Know? with a Bibliography of Fish Parasites in New Caledonia
    Belg. J. Zool., 140 (Suppl.): 155-190 July 2010 Parasites of coral reef fish: how much do we know? With a bibliography of fish parasites in New Caledonia Jean-Lou Justine (1) UMR 7138 Systématique, Adaptation, Évolution, Muséum National d’Histoire Naturelle, 57, rue Cuvier, F-75321 Paris Cedex 05, France (2) Aquarium des lagons, B.P. 8185, 98807 Nouméa, Nouvelle-Calédonie Corresponding author: Jean-Lou Justine; e-mail: [email protected] ABSTRACT. A compilation of 107 references dealing with fish parasites in New Caledonia permitted the production of a parasite-host list and a host-parasite list. The lists include Turbellaria, Monopisthocotylea, Polyopisthocotylea, Digenea, Cestoda, Nematoda, Copepoda, Isopoda, Acanthocephala and Hirudinea, with 580 host-parasite combinations, corresponding with more than 370 species of parasites. Protozoa are not included. Platyhelminthes are the major group, with 239 species, including 98 monopisthocotylean monogeneans and 105 digeneans. Copepods include 61 records, and nematodes include 41 records. The list of fish recorded with parasites includes 195 species, in which most (ca. 170 species) are coral reef associated, the rest being a few deep-sea, pelagic or freshwater fishes. The serranids, lethrinids and lutjanids are the most commonly represented fish families. Although a list of published records does not provide a reliable estimate of biodiversity because of the important bias in publications being mainly in the domain of interest of the authors, it provides a basis to compare parasite biodiversity with other localities, and especially with other coral reefs. The present list is probably the most complete published account of parasite biodiversity of coral reef fishes.

  • Sciaenops Ocellatus Geographic Range Habitat
    Sciaenops ocellatus Class: Actinopterygii Geographic Range The red drum, Sciaenops ocellatus, can be found along the Gulf Coast of the United States from Texas to Florida. It is also found along the United States east coast from Florida northward into northern Maine. The red drum can also be found along the Gulf Coast of Mexico, southward through Central America along the northern coast of Brazil southward to central Argentina. advanced intermediate Center for Quantitive Fisheries Ecology, 2014; Scharf and Schlight, 2000; Stunz and Minello, 2001 Biogeographic Regions: Nearctic; Neotropical; Atlantic Ocean. Other Geographic Terms: Habitat The red drum thrives in marine environments with various types of substrates. The red drum inhabits areas with oyster bottoms, unvegetated sand bottoms, and in marsh grasses along the coastline. The species will also inhabit deeper coastal waters, at a depth of up to 40 meters. On average, the red drum inhabits depths of 20 meters, but will be found in shallow waters along land in a depth of about 1 meter. Threat of predation and available food will influence the mean depth of the red drum. In the spawning seasons, the red drum will move into inlets and estuaries, primarily into the marsh grasses, depending on the tidal region, and can also survive in brackish water. advanced intermediate Powers et al., 2012; Wenner, 1992 Elevation: Depth: 1 to 40 m These animals are found in the following types of habitat: Saltwater or marine. Terrestrial Biomes: Aquatic Biomes: Coastal; Brackish Water. Wetlands: Marsh. Other: Estuarine. Physical Description The red drum is on average 100cm long and weighs 22kg, but individuals in the wild can be as long as 160cm and weigh 42.6kg.
