ABSTRACT
An ecological studywas conducted on species composition and monthly variations of marine macro algae with the fluctuating environmental parameters along Karwar coast, Karnataka, India between Jan 2018 to Jan 2019. A total of 11 seaweeds species were collected from Muduga coastal area. Chlorophyceae was represented by 5 taxa,Phaeophyceae was represented by 5 taxa and Rhodophyceae was represented by only one taxa.Both the phylum Phaeophyta and Chlorophyta were equal in dominance (each 5 species) than Rhadophyta. Monthly and seasonally seaweed distribution showed good abundances in pre-Monsoon and post-Monsoon rather than Monsoon, except for Phaeophyta group members.Occurrence and distribution varied with taxa according to environmental parameters but the green algal members were recorded abundant to other members.Pearson’s Correlation pictodiagram explaining significant relationship between physicochemical parameters and seaweeds abundancy revealed the positive and negative relationship.
