Regional study on small tunas in the Mediterranean including the Black Sea.
This study was undertaken upon request by the General Fisheries Commission for the Mediterranean (GFCM) and according to the suggestion made by the seventh meeting of the Joint GFCM/ICCAT Working Group on Large Pelagic Species. It summarizes the available information about different aspects of the small tuna species in the Mediterranean Sea and the Black Sea and provides data on their biology and ecology, their exploitation, including the fishery statistics by species, and the socio-ec onomic aspects of these fisheries. It is generally known that thousands of small- and medium-sized vessels, engaged in small-scale, artisanal or recreational fisheries, are carrying out activities that also target small tuna species. In addition, catches are also obtained as a bycatch in other fisheries. The fishery production is estimated at a minimum of about 150 000 tonnes. Considering only the total official production for the four most relevant species, it is likely that the estim ation of the real production might reach about 300 millions euros in the best years. A specific problem can be noted in relation to the small tuna species fishery in the Marmara Sea and in the Black Sea. Apart from Turkey, no recent data are present in any of the databases used for this study. The level of catches reported by Turkey in that area is, however, important. A secondary difficulty is the lack of data on fleet segmentation targeting these species, on catch per unit of fishing effort and on socio-economic parameters.
