Here, we characterized the structure and function of the coagulation factor II (FII) gene in grass carp and determined its role in coagulation mechanisms. The FII gene EST was obtained using a constructed splenic transcriptome database; the full-length FII gene sequence was obtained by 3' and 5' RACE. The open reading frame (ORF) of FII was cloned and the full-length gene was found to be 1718 b...

Field survey of Aquaculture farms in Basrah governorate was done during 2007. The study showed that there are 80 fish farm with total area 773.5 donum, while it 16 2003. 75 % the were less than 25000 m² (10 donum). 53.9 excavated pond, 34.2% concentration by half ground pools and 11.8 dyke pond. About 87.5 using pump 12.5 used tidal current for water supply. This 95 fishes source from Marine Sc...

Both acoustic and optical methods can be used for environmental monitoring of marine ranches. However, acoustic methods are more commonly used for underwater environmental surveillance. This paper presents the results of a study of the feasibility of using digital photography for monitoring the animals in an artificial reef. Animal monitoring studies enable us to characterize the behavior of aq...

The aim of the study was to estimate the effect of culture conditions and culture site on magnesium (Mg) and zinc (Zn) concentrations in freshwater fish. The study encompassed dorsal muscles in five fish species: common carp (Cyprinus carpio L.), rainbow trout (Oncorhynchus mykiss Walbaum) and Siberian sturgeon (Acipenser baeri Brandt), northern pike (Esox lucius L.) and grass carp (Ctenopharyn...

The aim of the study has been to estimate the effect of culture conditions and a culture site on magnesium (Mg) concentrations in freshwater fish. The study encompassed tissues (blood) and organs (gills, liver, kidney, dorsal muscles) of five fish species: common carp (Cyprinus carpio L.), rainbow trout (Oncorhynchus mykiss Walbaum), Siberian sturgeon (Acipenser baeri Brandt), northern pike (Es...

In the present study, genotoxic, histological and hematological effects of water pollution were evaluated in Ctenopharyngodon idella from Ili river. Water fish sampled at three sites. The concentrations following heavy metals measured water: Pb, Co, Mg, Cd, Cu, Zn, Fe. with gradually increased P1 to P3: P1, Cu Fe levels exceeded maximum permissible for culture, P2 – Fe, P3 river, highest freque...

6-Phosphogluconate dehydrogenase (6-PGD, E.C.: 1.1.1.44) was purified and characterized from the hepatopancreas of grass carp (Ctenopharyngodon idella) for the first time. Grass carp represents the second largest aquaculture industry in the world after silver carp, constituting 14.7% of the world aquaculture production, with an average annual increase of 14% in China, mainly as a source of food...
