The researchers studied the benthic environment and polychaete communities in Gamak Bay to see how pollution affects them. They found that areas with high organic content and pollution had fewer species of polychaetes. In the summer, stations near the harbor and fish farms had more polychaetes, while in the winter, different species dominated. The researchers also discovered that the disturbance level in different parts of the bay influenced the types of polychaetes found there. Overall, the study showed that pollution and environmental factors play a significant role in shaping the polychaete communities in Gamak Bay.
