G. SMITH, J. D. SIBUNKA, and A. WELLS SEATTLE, WA June 1975 ATMOSPHERIC ADMINISTRATION / Fisheries Service NOAA TECHNICAL REPORTS National Marine Fisheries Service, Special Scientific Report—Fisheries Series The majnr responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of these resources, and to establish levels for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through- marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The Special Scientific Report—Fisheries series was established in 1949. The series carries reports on scientific investigations that document long-term continuing programs of NMFS. or intensive scientific reports on studies of restricted scope. The reports may deal with applied fishery problems. The series is also used as a medium for the publica- tion of bibliographies of a specialized scientific nature. NOAA Technical Reports NMFS SSRF are available free in limited numbers to governmental agencies, both Federal and State. They are also available in exchange for other scientific and technical publications in the marine sciences.

There are four major families of flatfish with representative species found in the Gambian nearshore waters: Soleidae, Cynoglossidae, Psettododae and Paralichthyidae. The species below have been confirmed through literature review, and through discussions with local fishermen, processors and the Gambian Department of Fisheries.

Flounders Are Flat Fish Which Live on the Sand at the Bottom of the Ocean, Usually in Inlets and Estuaries
Fall 2013 Newsletter That Time of Year The word autumn first came to be used in the fourteenth century, and it’s usually associated with an end of things, such as the saying, “the autumn of life”. Around here, autumn is the second best season (after all, summer just can’t be beat). During the first part of fall we can still wear flip flops and shorts, and the ocean water is still warm, but the evenings start getting a pleasant chill in the air, and the drive down Ocean Isle Beach Road is ablaze with color. There’s also the OIB Ghost Walk, and the Longwood Haunted Trail to look forward to. For you fishermen out there, the spots and flounder will soon be running. There’s also the Annual OIB Oyster Festival, which will run October 19 and 20. Fall is also the start of the football season. It doesn’t get much better than that. Flounder Flounders are flat fish which live on the sand at the bottom of the ocean, usually in inlets and estuaries. They’re also called Flukes, or Flatfish. They don’t have an air bladder, like most fish, so they can stay on the bottom very easily. They tend to “hide” in the sand by camouflaging their body the color of the sand surrounding them. They do this so well, that a predator could be swimming right next to one and not see it. Flounders are carnivorous, feasting mainly on shrimp and small crabs. The male flounder can grow up to about twelve inches long, but the female can sometimes reach 25 inches.
