In order to examine the health of the coastal waters off Visakhapatnam in terms of prevalence and abundance of heterotrophic (H), indicator and pathogenic (P) bacterial counts (BC) and influence of physical processes on them, time-series observations were conducted during January (winter), March (spring), July (summer) and October (post-monsoon). We noticed the impact of physical forces on substantial variations in abundance and distribution of the HBC, total coliforms, Enterococcus faecalis and Pseudomonas aeruginosa in the study region. Based on our results Escherichia coli and other PBC were not much influenced by the physical conditions. It has been noticed that the perennial existence of the high abundance of IBC and PBC above the standard limits during the entire study period leading to an alarming situation in the coastal waters off Visakhapatnam.
为了研究维沙卡帕特南沿海水域的健康状况，我们检测了异养（H）、指示和病原（P）细菌计数（BC）的流行率和丰度，以及物理过程对它们的影响。在 1 月（冬季）、3 月（春季）、7 月（夏季）和 10 月（后季风期）进行了时间序列观测。我们注意到物理力量对研究区域 HBC、总大肠菌群、粪肠球菌和铜绿假单胞菌的丰度和分布的重大变化有影响。根据我们的结果，大肠杆菌和其他 PBC 受物理条件的影响不大。我们注意到，在整个研究期间，IBC 和 PBC 的高丰度常年存在，超过标准限值，导致维沙卡帕特南沿海水域的情况令人担忧。
