Heterotrophic bacteria density in the near shore waters and intertidal sediments was studied from May 2014 to May 2015 at fortnightly intervals from five stations. The mean values of water temperature, salinity, dissolved oxygen, pH and sediment organic matter were 28.6°C, 34.9 ppt, 4.73 mg/l, 7.7 and 0.73% respectively. The total bacteria density in the near-shore waters ranged from a low density of 213 x 10³ cfu/ml (Station 2; May II) to a high density of 463 x 10³ cfu/ml (Station 3; November II) and averaged to 334 x 10³ cfu/ml. The total bacteria density in the intertidal sediments fluctuated between 172 x 10³ cfu/g (Station 1; March II) and 475 x 10³ cfu/g (Station 3; December II) and averaged to 316 x 10³ cfu/g. Significant negative correlations are observed for salinity, DO and pH at Station 2. Significant positive correlations are recorded for water salinity and sediment temperature at Station 4. The paper discusses the impact of physico-chemical parameters on the density distribution of bacteria along Visakhapatnam coast.
