Grouper fishery in the Northeastern Mediterranean: An assessment based on interviews on resource users

Groupers are important components of coastal ecosystems as well as a valuable resource for fisheries. Their populations are known to be decreasing throughout the world primarily due to over-exploitation. However, even the basic data for an effective management strategy is lacking. Interviews of a representative sample of 113 fishers in Turkey in the northeastern Mediterranean were conducted with specific questions regarding fishing gears, periods and areas as well as best day's catch and the sizes of fishes caught. Fishermen recognized Epinephelus marginatus, E. aeneus, E. costae, Hyporthodus haifensis, Mycteroperca rubra and Polyprion americanus distributed in the area. “Endangered” E. marginatus and “Near Threatened” E. aeneus were the dominant species of the grouper fishery. Based on best days’ catch values and reported lengths of fish caught, the northern coasts of Iskenderun Bay were found to be important for both species. Demersal longliners, spearguns, traps, anglers and demersal trawlers were reported catching groupers in the study area. Artisanal fishermen, especially demersal longliners contributed the most to the grouper fishery. Fishing pressure were subject to seasonal fluctuations, with decreasing reported catches during summer when threatened groupers spawn. Finally, some critical aspects of fishery pressure were related to the removal of juveniles which may lead to reproduction loss. © 2017 Elsevier Ltd Rufford Foundation: 20449-1 This study was performed as a part of the project “Strongholds for Groupers in Iskenderun Bay: Defining Conservation Hotspots for Sustainability” granted by The Rufford Foundation with the grant number 20449-1 .
