Abstract
Monthly sampling of red algae was carried out from April 2005 to March 2006 in Chabahar coasts (southestern of Iran) along Sistan & Baluchistan province coastal waters. We considered monthly periods of maximum tide according to tide tables. Then seaweed growth area in intertidal zones was determind through GPS, GIS and satellite imagery. Monthly sampling was conducted on a number of transects with equal distance and in randomly chosen 50×50cm quadrates. The samples were transfered to Offshore Waters Research Center’s lab and after cleaning and separating, the weight of each species recognized was measuerd according to the present references. The biomass of each species was obtained per area unit and in the total area after determing the average weight of species. During this research, 13 species of medicinal red algae were recognized, and the most important families included: Gelidiaceae, Gracilariaceae, Hypneaceae and Rhodomelaceae. Total biomass in the area of Chabahar Coasts were 865.2 tons and the monthly average was 72.1 tons. The maximum biomass was obtained in February as 149.8 tons (828g/m2) and the minimum biomass was seen in May as 16.3 tons (90.2g/m2). The maximum biomass belonged to Gracilaria corticata (%33.1) and the minimum biomass to Hypnea pannosa (%1). *Corresponding author

Abstract
Sargassum oligocystum and Nizamudiinia zanardinii are the most abundant algae distributed
in the north of Persian Gulf and Oman Sea. In this study after sampling and preparation of S.
oligocystum by Chroform-Etanol (3-1) solvent and N. zanardinii by methanol has been
extract. Separation and purification of the compounds was carried out using thin layer, general
and inverse column chromatography, Cephadex and high-performance liquid chromatography
(HPLC ).. Structural elucidation of the constituents was based on the data obtained from HNMR,
13C-NMR, HSQC, HMBC, DEPT and Cephadex LH-20. The steroids compounds
separated from above algae were identified as 22-dehydrocholesterol (1) cholesterol (2)
fucosterol (3) 29-hydroperoxystigmasta-5,24(28)-dien-3β-ol (4) 24-hydroperoxy-24-
vinylcholesterol (5) a mixture of 24(S)-hydroxy-24-vinylcholesterol (6) and 24(R)-hydroxy-24-
vinylcholesterol (7) and ostreasterol (8) based on their spectral data and from comparison with
those previously reported in the literature.

Abstract
This study was carried out to determine the Seaweed biomass in the coast of Sistan & Baluchestan Province. Beris, Chabahar, Pozm and Tang were introduces as high density zones and Jood & Lipar were selected as low density zones.
From 354.2 km of investigated coastal area, among this, 18.2 km were high density zone and 281.5 km were low density zone. Three transects were fixed in studies area and sampling randomly were done monthly. The samples were measured in area after being cleaned, and separating. During this research, 9 genus were collected. Among these seaweeds, 2 genus were green algea (composed of 2 families and 2 orders), 6 genera of brown algae (composed of 3 families and 3 orders) and 1 genus of red algae.
Wet biomass of Sargassum genus in the total area of Sistan & Baluchestan coasts was 445.9 tons in 2012. Among this biomas, 269.1 tons (%60.35) was found in high density area and 176.8 tons (%39.65) in low density zone. The maximum biomass was obtained 270.4 tons (high density zone: 155.5 and low density zone: 114.9 tons) in Dec. and the lowest biomass was obtained 3.5 tons in March.

Abstract
The species of the Ruppia maritima were Sampled from Caspian Sea coasts and Water Channel of Shrimp Pond in Golestan Province in Summer of 2016.
Identification and Confirmation of Species Scientific name performed by Internal References and Relasionsheep to Forien Experts. The density of these species usually are very abundant in Caspian Sea coasts . This Species belonged to Kingdom of Plantae, Phylum of Tracheophyta, Class of Angiosperm, Order of Najadales, Family of Ruppiaceae, Gunes of Ruppia and species of maritima. The distribution of the species is very large in world and often is in tropical and semi tropical area of Sea and Ocean. These species growing on mudy and mudy - sandy substrates with rhyzom and are primery productions in sea, also these species are suitable sheltered for important and commercial aquatic nursery. So, a little study performed in these case, because, in this research be identified and introduced these planes as other one of aquatic sourse of Iran.
