Title

Seaweed species diversity along the intertidal region of Loej, Saurashtra coast, Gujarat, Arabian Sea

Abstract

Loej coast situated near Mangrol of Saurashtra region, Arabian Sea, Gujarat is supported by diverse flora and fauna. The present study aimed to document seaweed diversity and distribution along intertidal region of Loej coast by using belt transect sampling method from October 2021 to March 2022. From the study area, a total of 56 seaweed species belonging to 3 phyla, 3 classes, 16 orders, 25 families and 36 genera were recorded. Out of these 12 species were green seaweed, 14 species
were brown and 30 species were red seaweed. Maximum number of species diversity was reported from class Rhodophyceae. Dictyotales (16%, species) was found to be dominant order followed by Gigartinales (14%, species); Ceramiales (11%, species). Among 25 families, Dictyotaceae was the dominant family reported with 14 species. Distribution study observed vertical distribution from the seashore side to the seaside of green, brown and red seaweed. Also, horizontal distribution of green seaweed and red seaweed were seen in the upper intertidal area and in the lower intertidal area, respectively. In species distribution behaviour, out of 56 species of seaweed; 8 species show aggregated behaviour, 10 species show the regular distribution and 38 species show random aggregation behaviour. Ulva lactuca was most abundantly and frequently found species with maximum density during the whole study period. During the present study, diversity indices like species diversity index (H’) indicate healthy diverse seaweed fauna. Species richness index/Margalef’s diversity index (D) was in the range of 3.37-4.81. Maximum species richness was reported in winter month February and minimum species richness in October. Pielou’s evenness index (J) showed that seaweed species were unevenly distributed.
