Abstract

In the rapid development of marine aquaculture, the water quality of aquatic environments is regarded as a main limiting factor. Physicochemical characteristics of seawater play crucial role for productive marine ecosystem and fisheries activities. In the present study, the physico-chemical parameters such as sea surface temperature, salinity, pH, and dissolved oxygen were studied for a period of 12 months (July 2019– June 2020). Sea surface temperature varied from 25.5 to 32.5 °C. Salinity varied from 28.0 and 37.0 ‰, hydrogen ion concentration ranged between 7.15 and 8.22. Variation in dissolved oxygen content was from 3.86 to 5.85 mg l−1. In the present study the seasonal variations of various factors were studied and interrelationships existing between them discussed.
