Abstract

A research aims to determine the abundance of Dog Conch (Strombus turturella) and its relationship with water quality in the coastal area of the Tanjungpinang Kota Sub District was conducted in December 2012 to January 2013. The method used in this research is a survey method. Water quality parameters measured were temperature, turbidity, pH, salinity and DO, while Dog Conch (Strombus turturella) studied were abundance. Result shown that abundance of the Dog Conch (Strombus turturella) ranged from 31852 ind/ha – 37407 ind/ha. Water quality parameters are as follow: temperature ranged from 28,3 to 32,00 ° C; salinity ranged from 24,33 to 29,67 ‰; turbidity ranged from 5 - 11 NTU; dissolved oxygen ranged from 1,73 – 2,33 mg/l. Organic materials present in the substrate ranged from 28,80 - 49,07 %. Turbidity level were more than the standard issued by Indonesian Government (KepMen LH No.51. 2004).
