Parâmetros Populacionais de Caretta caretta (Linneaus, 1758) em Praia do Forte , Mata de São João , Bahia, Brasil

Abstract

The loggerhead sea turtle, Caretta caretta has circunglobal distribution occurring in tropical seas, subtropical and temperate of the major ocean basins your status in the world is classified as Vulnerable A2B (IUCN, 2016). In south eastern Atlantic, nesting occurs in the Brazilian coast, with the most records, compared to other species that occur on our beaches. In Brazil the population is recovering and the main nesting areas are protected by the Projeto TAMAR. Although we know a lot about the species there are no parameters to estimate the population of loggerhead turtles in Brazil. Monitor trends in populations is important for the managements of endangered species. To do this more assertively is necessary to use own population’s parameters to be inserted in population models. Thinking about this need was planned a sample design to increase female meeting applied in observing the loggerhead turtles that nest in Praia do Forte, Mata de Sao Joao, Bahia. The sample design was tested in the nesting season of 2008 and successfully applied between 2009 and 2015. We estimated the Internidal Period PI (15 days) Estimated Clutch Frequency ECF (4 DP 1), and remigration IR range (two seasons) important parameters to perform estimates of the population of C. caretta Brazil.
