There were several factors that influence the difference in the values of parameters between the two months. These factors include the weather condition, location of sampling sites, tidal regime and anthropogenic activities from the nearby villages. Fisheries survey shows that the common technique that was practiced by the harvesters in Bako is using `lidi' stick and lime. Species that are found in Bako are Solen regularis, Solen sarawakensis, and Solen digitalis. This study found that the water quality in Bako is still sustainable for the growth of razor clams.
