Habitat-specific spatio-temporal patterns of Scartelaos histophorus on the bhavnagar district coastline: Insights from environmental correlates

Abstract

The Kathiawar Peninsula's coastal areas, crucial for Arabian Sea trade, face significant human impact from industries and fishing, potentially affecting intertidal life. The study explores the population dynamics of the mudskipper Scartelaos histophorus in the coastal area of Bhavnagar district, Gujarat, India, focusing on its ecological status along the muddy-rocky intertidal coastline. The research, using the quadrat method, categorized data into four seasons from 2022-23 to 2023-24. Hathab Coast showed the highest density and abundance of Scartelaos histophorus due to muddy habitats, while Ghogha had significant mangrove coverage. The mudskipper population characteristics were strongly correlated with the quantity and thickness of the mud layer, as it constructs burrows in the muddy substrate. Scartelaos histophorus was predominantly found in the upper intertidal zone during low tides.
