The western coast of Gujarat, India, specifically the Veraval coastal area, was the site of the present study, which is situated at 20˚54 N latitude and 70˚21 E longitude. It has a flat, rocky inter-tidal belt with numerous tidal pools and crevasses. Seaweeds were noticed intermittently; some species were only seen for brief periods, whereas others were obtainable for two to three months. From October 2020 to February 2022, seaweed was harvested from the inter-tidal zones during the experiments. Seaweeds were found during the study period, but they weren't always there. Some species were only observed for a brief time, and other species only appeared during a particular season. The species that were collected were taxonomically identified and categorized. A checklist of the species available was prepared along with their potential utilization. A total of 83 species were identified throughout the investigation, with Rhodophyta having more species than Chlorophyta and Phaeophyta collectively. During the diversity survey, economically important species like Ulva lactuca, Ulva fasciata, Sargassum sp., and Caulerpa sp., were reported. Among them, Ulva lactuca, Sargassum sp. was highly dominated followed by Gracilaria spp.

Abstract [Persian]

سواحل غربی گجرات، هند، به ویژه منطقه ساحلی Veraval، محل مطالعه حاضر بود که در عرض جغرافیایی 20 درجه شمالی و طول جغرافیایی 70 درجه شمالی واقع شده است. این منطقه دارای یک کمربند بین جزر و مدی صاف و صخره­ای با حوضچه­های جزر و مدی و شکاف­های متعدد است. جلبک­ها در دوره­های نامنظم ظاهر می­شدند. برخی از گونه­ها فقط برای دوره­های کوتاهی دیده شدند، در حالی که برخی دیگر برای دو تا سه ماه قابل دستیابی بودند. از اکتبر 2020 تا فوریه 2022، جلبک­ها در طول دوره آزمایش­ها از مناطق بین جزر و مدی برداشت شد. در طول دوره مطالعه برخی از گونه­ها فقط برای مدت کوتاهی مشاهده شدند و گونه­های دیگر فقط در طول یک فصل خاص ظاهر شدند. گونه­های جمع­آوری شده شناسایی و دسته­بندی شدند و چک لیستی از گونه­ها به همراه استفاده بالقوه آنها تهیه شد. در مجموع 83 گونه در طی بررسی شناسایی شدند و در مجموع جلبک­های قرمز (Rhodophyta) گونه­های بیشتری از جلبک­های سبز (Chlorophyta) و قهوه­ای (Phaeophyta) داشتند. در طی بررسی، گونه‌های مهم اقتصادی مانند Ulva lactuca، Ulva fasciata، Sargassum spp. و Caulerpa spp. گزارش گردیدند که در میان آنها، Ulva lactuca، Sargassum spp. و بعد از آن‌ها Gracilaria بسیار فراوان‌تر بودند.
