EXPLOITATION RATE OF MEAT OYSTER (CRASSOSTREA GIGAS) AGAINST THE DYNAMICS OF ITS POPULATION IN THE COASTAL AREA OF BANDA ACEH

Research on the rate of exploitation ofmeat oyster especially Crassostrea gigas to the dynamics of its population has been conducted in Banda Aceh, Aceh Province. This study was conducted in 6 months starting from July to December 2017. Surveys and activities were conducted in two locations: Tibang and Ulee lheue, where samples were collected at least 150 samples per location per month. Data collection was done by line transect method. Total samples of oyster collected 1800 samples, where all samples fall into the adult category. The long frequency value was dominated by 40-50 mm long class with estimated age of 1 year oyster. Analysis of the rate of mortality showed the total mortality rate (Z) reached 7.22year-1 , natural mortality rate (M) 1.27year-1 , the catching mortality rate (F) 5.95year-1 and the exploitation rate (E) 0.82year-1 . Based on the data of the rate of exploitation indicates that the activity of oyster catching has been included in overexploitation category.
