Journal Title: International Journal of Life Science - Year 2018, Vol 6, Issue 1
Abstract
This study highlights the seasonal variation in polychaetes of intertidal mangrove area of Shirgaon, Ratnagiri, Maharashtra. All polychaetes sample was collected by stratified random sampling method during the lowest low tide of each month. A total of six polychaetes species viz; Nereis sp., Perinereis sp., Lumbrinereis sp., Marphysa sp. I, Marphysa sp. II and Unidentified polychaetes sp. were recorded. The abundance of polychaetes during pre-monsoon (3.5442 no m-2), monsoon (2.5714 no m-2) and post-monsoon (2.8571 no m-2) was recorded among which Nereis sp. and Marphysa sp. were recorded consistently in all season while other polychaete species were sporadically distributed in all three seasons. Monthly variation in-situ parameter such as atmospheric temperature, intertidal water temperature, sediment temperature, dissolved oxygen of intertidal water, intertidal water pH, sediment pH, sediment organic carbon and intertidal water salinity were recorded during the study period.
