The diversity of macro and meiobenthos was documented in order to assess the ecosystem health of an anthropogenically impacted coastal ecosystem for the first time along the southwest coast of Tamil Nadu. Offshore sediment and water samples (n = 63) were collected from 14 sampling stations using the grid sampling method. Water and sediment samples were analysed for environmental variables such as pH, temperature, electrical conductivity (EC), total dissolved solids (TDS), salinity, sulphate, dissolved oxygen (DO), carbohydrate (CHO), protein, lipid, labile organic matter (LOM), total organic carbon (Corg), total organic matter (TOM) and sediment texture using standard methods. Benthic macro and meiobenthos were isolated and identified using standard identification keys. A total of 5 phyla of macrobenthos with 29 species and 5 phyla of benthos with 60 species were identified in the study area. Relative abundance analysis showed that the largest numbers of species belonged to Polychaeta for macrobenthos and foraminifera for meiobenthos. Redundancy analysis indicated that sediment carbohydrate content was the highest determining factor for explaining variation in the diversity of benthos. AMBI & M-AMBI results revealed that among the 14 stations, 2 were categorized as “poor” and 9 as “bad”. Multiple anthropogenic activities in the coastal environment leading to increased organic matter input have resulted in a decline in the ecosystem health of this region, which warrants site-specific management to control organic pollution.

Macrozoobenthos is related to certain substrates in accordance with its adaptability and ecological function. The existence of macrozoobenthos on the coast of Sembilang National Park needs to be studied ecologically. The study purpose was to study the ecology and biodiversity of macrozoobenthos and its relationship with the environment in the mudflat zone. Macrozoobenthos sampling used the stratified sampling method at four stations. Each station consisted of three substations based on the supratidal zone, the intertidal zone, and the subtidal zone. Macrozoobenthos was taken from the surface to a depth of 20 cm on quadrant transects. The macrozoobenthos found consisted of 3 classes, 16 species, and 442 individuals. The highest macrozoobenthos composition was the Gastropoda class, with a total of 60%. The highest abundance of individuals was found at station 1 of the subtidal zone with a total of 222 Ind./m2, which is the species Cerithidea cingulata in the Gastropoda class. Based on the study results, we were able to conclude that the macrozoobenthos community biodiversity index was closely related to the higher availability of dissolved oxygen and higher sand concentrations along the mudflat zone. This system would affect the macrozoobenthos existence found in the environment, especially in Sembilang National Park.
