Relationship Between The Occurrence Of Noctiluca Scintillans Bloom And Physicochemical Characteristics Of Seawater Off Bhatye Beach, Ratnagiri, Maharashtra
Main Article Content
Abstract
Harmful algal blooms (HABs) pose a significant threat to marine ecosystems, impacting both aquatic organisms and coastal communities. Noctiluca scintillans, a bioluminescent dinoflagellate, is a substantial contributor to HABs worldwide, particularly along the coastal regions of Bhatye Beach, Ratnagiri. This research explores the intricate relationship between the occurrence of Noctiluca scintillans blooms and the physicochemical characteristics of seawater in the specified region. Conducted from November 2022 to January 2023, the study involved comprehensive field investigations and data analysis, focusing on elucidating the environmental factors influencing the proliferation of Noctiluca scintillans. Physicochemical parameters assessed included phosphate, nitrate, nitrite, silicate, temperature, salinity, pH, and Dissolved Oxygen. The findings provide valuable insights into understanding the dynamics of Noctiluca scintillans blooms in the coastal waters of Bhatye Beach, Ratnagiri, and lay the foundation for developing effective monitoring and management strategies to mitigate the impact of HABs in this ecologically sensitive region.
