Characteristics of Marine Environment in Coastal Waters for Stationary Fisheries.- Physical and Chemical Environments

To illustrate the characteristics of marine environment in coastal waters of stationary fisheries, field observations were carried out in August and November, 2001. Water temperatures in Jindong Bay compared with those in Masan Bay were about higher in August and about in November. Salinities were lowest in the western part of Jindong Bay. It was found that salinity increased gradually from the western part of Jindong Bay to Masan Bay. Sea water in Masan Bay can be characterised as lower temperature and higher salinity, compared with those in Jindong Bay. Concentrations of suspended solids in the inner parts of Jindong Bay were higher than 15mg/L in August. Suspended solids in both regions of Jindong Bay and Masan Bay showed contrastive distributions, especially in November. That is, higher concentrations of suspended solids were found in the inner parts of Jindong Bay and off Masan Bay. Concentration of chemical oxygen demand in Masan Bay was highest, 7mg/L.
