dc.description.abstractResearch the distribution and growth patterns of mud crab S. tranquebarica in mangrove ecosystem Belawan, North Sumatra has been done. The research aims to determine the physical chemistry characteristics of mangrove ecosystem with the distribution of mud crab S. tranquebarica based on size class and gender, determine growth pattern of mud crab S. tranquebarica in Belawan mangrove ecosystem, North Sumatra. Habitat characteristics of mud crab based on physical chemistry parameters in each station were analyzed using principal component analysis, growth pattern with linear regression and distribution of mud crab based on size class and gender using correspondence analysis. The result of principal component analysis able to classify three groups of stations. The first group consists of station I and V are characterized by nitrate, phosphate and high clay substrate. The second group consists of station II and III are characterized by substrate pH, salinity and high sand substrate. The third group consists of station IV is characterized by substrate temperature and high clay substrate. The result of the analysis distribution of size class and gender shows small size of male and female mud crab were distributed in habitat had nitrate, phosphate and high clay. Medium size of male and big female were distributed in habitat had substrate pH, salinity and high sand substrate. Large male and medium size femal were distributed in habitat had substrate temperature and high dust substrateen_US
