Correlation of Rhopilema hispidum with Hydrobiological Parameters from Coastal Waters of South Konkan, West Coast of India

Present study was conducted along the coastal waters of Ratnagiri, West coast of India from October 2023 to May 2024. Total 15 individuals of Rhopilema hispidum belonging to genus Rhopilema were caught in trawl net. Spearmen correlation was done to correlate Rhopilema hispidum with hydrobiological parameters. Result showed significant positive correlation with water pH and nutrients such as phosphate and silicate, while negative correlation was observed with nitrate, nitrite and water temperature. Positive correlation was observed with fish species such as Arius maculatus, Alepes djedaba, Cynoglossus arel, Epinephelus diacanthus, Gerres filamentos and other fish species. High abundance of Rhopilema hispidum was recorded when high nutrient concentration of phosphate and silicate were recoded.
