ABSTRACT
Seasonal variation of seaweed diversity was studied in three stations namely Majali, Tilmati and Muduga of Karwar, kanara coast of Karnataka, India. An extensive survey on seasonal changes of seaweed diversity was performed and the data were analyzed for seaweeds abundancy. The rocky intertidal zone was visited fortnightly to record the occurrence of seaweeds during study period from Jan 2018 to Jan 2019. Congreg ated species of seaweeds were collected and segregated according to variable groups from Majali, 40 species, Tilmati consists of 23 species and Muduga consists of 11species.Pre-monsoon and Postmonsoon seasons were viable for seaweeds abundancy whereas Monsoon played important season for some of strong tensile genus Sargassum at all three study stations. Abundance of seaweeds (no/m2) were represented as pie chart in form of percentage showed good numbers in Pre-monsoon and Post-monsoon seasons. Pearson’s correlation coefficient ‘r’ was used to state the weak and strong relationship between parameters and species. The baseline data generated will aid in conservation of the seaweeds in the areas
