ABSTRACTGROWTH CHARACTERISTICS OF THE SILVERSTRIPE BLAASOP (Lagocephalus sceleratus Gmelin, 1789) IN ANTALYA BAYSuna TÜZÜNM.Sc. Thesis, Department of BiologySupervisor: Prof. Dr. Murat BİLECENOĞLU2012, 41 pagesIn this study, growth characteristics of the silverstripe blaasop (Lagocephalus sceleratus Gmelin,1789) was investigated in Antalya Bay. A sample of 321 fish with total lengths ranging from 5.9 cm to 46.3 cm was collected from trawl and coastal fisheries between April 2010 and November 2011. Growth and length data were measured from 115 of the fish, with a length ? weight relationship of W = 0,0228L2,9109. Growth parameters of Lagocephalus sceleratus were calculated using the ELEFAN-I routine of the FISAT-II software, using length frequency data. In length frequency analysis, seasonal data was used and data was classified as per 2 cm length groups, containing three seasons: summer (June + August), spring (April) and fall (September + November). The von Bertalanffy growth equation was calculated as Lt = 48.2 [1 - e -0.52 (t + 0.27)].Key words: Lagocephalus sceleratus, Antalya Bay, Growth characteristics
