Shrimp aquaculture has expanded rapidly in many countries and this rapid development resulted diseases outbreaks and further considerable utilization  of antibiotics. Use of natural products as antimicrobial has been reported as a resolution problem. The crude extract of a red seaweed (Laurencia snyderiae) collected from the Persian Gulf was evaluated for shrimp growth performance and to d...

Bycatch studies have largely ignored population level effects on fish species of little commercial interest. Here we analyze bycatch of the lined seahorse (Hippocampus erectus) in the bait-shrimp trawl fishery in Hernando Beach, Florida, providing the first fisheries data for this species. Based on catch per unit of effort (CPUE), size, sex, and reproductive status of trawled H. erectus, 1) app...

In the past decade, the investment in fisheries development has grown remarkably in the Persian Gulf region. A 1800 km of northern coastline of the Persian Gulf, the Oman Sea and more than 14 islands belong to Iran have provided great possibilities of economic activities. In-shore marine islands such as Kish, Farour, Hendurabi, Tonb made a good opportunity for fishing and harvesting of ornament...

in this study, three stations of the north persian gulf were analyzed in order to determinethe effect of trophic levels on the concentration of harmful pahs in fish and sediment. in all cases,similar distributions were observed in which benzo(a)pyrene largely predominated andbenzo(b)fluoranthene and pyrene were the second major compounds in fish tissues. the predominantcomponents of pahs in sed...

B etween 1986 and 1998, the price of a barrel of West Texas Intermediate (WTI) oil remained quite stable, fluctuating between $16 and $42 (in constant 2011-U.S. dollars), with the exception of a brief spike in 1990 at the time of the first Gulf War. In December 1998, the barrel of WTI had reached a low point of $17. Almost 10 years later, in July 2008, the same barrel cost $134. By March 2009, ...

the first season of survey at qeshm, carried out during the winter of 2006, resulted in the identification of nine sites from the parthian and sasanian periods. the surface pottery from these sites suggests their trade and cultural relations with contemporary sites in the southern persian gulf and other areas. for instance, the parthian and sasanian glazed types in qeshm island are closely re...

Two new species of Palapedia Ng, 1993, are described based on material collected from Abu-Musa Island, Persian Gulf during the present study, from Bahrain by the 1937/38 Danish Expedition, and from the Saudi Arabian coast of the Persian Gulf by Michael Apel in 1992-1995. Palapedia persica n. sp. is distinguishable from its congeners by having distinctly large denticles on the upper margin of th...

New record and new species of the families Melitidae Bousfield, 1973 and Maeridae Krapp-Schickel, 2008 are described from the Iranian shorelines of the Persian Gulf. Melita persia sp. nov. is differentiated from other members of M. zeylanica Stebbing, 1904 group by: the presence of two setae on inner ramus of third uropod, the setal arrangement on the telson, and a recurved proximal lobe of six...
