Extraction and identification of steroids in two species marine algae, Sargassum oligocystum and Nizamudiinia zanardinii in Persian Gulf and Oman Sea

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

Species diversity in Iran aquaculture

Species diversity of aquaculture based on introduction of endemic and exotic species, for various object to aquaculture industry. AS FAO reports in 2012, about 558 different aquatic species have been used for aquaculture production. Among these, 130 marine fishes, 169 fresh water fishes, 45 species of migratory fishes, 62 crustacean, 35 aquatic plants, 4 aquatic products (pearl,), 98 invertebrates and finally 15 other aquatics included. Increasing of world aquaculture production depended on species diversity, and exotic species play the highest rank in this field. Aquaculture development program in Iran emphasized special attention on species diversity since last half century. Wide studies and researches devoted on biology, and exotic species. Iran aquaculture industry studied 27 different exotic species, and 28 endemic species for aquaculture development and sea ranching program. In addition, about 250 different ornamental aquatics, mainly non- native included in house- aquariums. Six different exotic species have the main aquaculture production in cold water, warm water and sea water environments. Rainbow trout is the main species in cold- water, while high valued endemic species of Caspian salmon has not any role in aqua culture production. In warm water fish group, chines carps and common carp are main species, but endemic species same as shirbot, Gattan, Benny and Schizotrox have not used in aquaculture production. Despite of wide researches on marine fishes of north and south sea, not endemic fishes included in aquaculture production. The new developing production of marine fish relied on non- native fish. Although specific duration of shrimp culture based on endemic species of Penaeus indicus, it is about of 10 years that shrimp production relied on exotic species of P.vannamei. In case of sturgeon fish, this new enterprise based on endemic species of Huso huso. Finally, the aquaculture industry of Iran same as most other countries relies on exotic species

The study of some limnological study of the Kan river in the catchment area of the Persian Gulf Martyrs Lake (Chitgar), Tehran trophic index in Anzali lagoon

This study focused on identification phytoplankton, zooplankton, benthos, fishes and relationship between biotic and abiotic parameters at three stations in the Kan river during 2014. This study identified 19 phytoplankton taxa. The findings showed, the diatoms abundance were dominated in the river. The chlorophytes abundance were recorded the lowest abundance in this study. The nutrients and water temperature were the significant abiotic parameters to increase cyanophytes and chlorophytes abundance in the Kan river. This study identified 26 zooplankton taxa. The Rotatoria and Protozoa abundance were dominated in the Kan river. Based on CCA, there was no correlation between abundance zooplankton and abiotic parameters. The biodiversity index of plankton was between 1.8 and 2 and the lake situation is located in the mesotrophic category. The study of the Kan river fishes showed, only one endemic fish species Capoeta bohsei. The length (between 38 and 270 mm, average 144±86 mm) and weight (between 1.1 and 356 g, average 108.8±146.7 g) of the C. bohsei were varied during the study period. The 19 benthos taxa were identified. The Ephemeroptera was most abundant in the benthos groups. The classification of river based on biology indicator and environmental parameters confimed that water quality is located in the moderate category

Effect of Water Blocking Damage on Flow Efficiency and Productivity in Tight Gas Reservoirs

Tight gas reservoirs normally have production problems due to very low matrix permeability and significant damage during well drilling, completion, stimulation and production. Therefore, they might not flow gas at optimum rates without advanced production improvement techniques. The main damage mechanisms and the factors that have significant influence on total skin factor in tight gas reservoirs include mechanical damage to formation rock, water blocking, relative permeability reduction around wellbore as a result of filtrate invasion and liquid leak-off into the formation during fracturing operations. Drilling and fracturing fluids invasion mostly occurs through permeable zones or natural fractures and might also lead to serious permeability reduction in the rock matrix that surrounds the wellbore, natural fractures, or hydraulic fracture wings.This study represents evaluation of water blocking damage in tight gas formations, and the influence on core flow efficiency and well productivity. Core scale reservoir simulations were carried out based on a typical Western Australia tight gas reservoir in order to numerically model liquid invasion during overbalanced, balanced and underbalanced drilling, and the effect on gas production in clean-up period. The simulation results describe how water blocking reduces near wellbore permeability and affects well productivity and gas recovery from tight gas reservoirs
