Bacterial diseases in cultured fish are considered the main problem with aquaculture system in Iran. The gills are multifunctional organs responsible for respiration, osmoregulation, nitrogenous waste excretion, and acid-base balance. Moreover, they are very sensitive to water contamination. Aeromonas hydrophila (A. hydrophila) is an opportunist pathogen responsible for ...

Toxicity of the extracellular products (ECP) and the lethal attribute of serine protease secreted by five pathogenic Vibrio alginolyticus strains from various sources in kuruma prawn Penaeus japonicus were studied. The ECPs of organisms originally isolated from diseased kuruma prawn or small abalone Haliotis diversicolor supertexta were more lethal (LD50 value of 0.48 or 0.41 microg protein/g p...

In Benin, the tarsonemid mite Polyphagotarsonemus latus (Banks) (Prostigmata: Tarsonemidae) is a key pest of gboma eggplant Solanum macrocarpon (L.) (Solanales: Solanaceae), a leafy vegetable on which it causes considerable damage to the plants and substantial reduction in yield. Predatory mites in the family Phytoseiidae have been successfully used in the biological control of numerous agricul...

Abstract In the present study, effects of dietary supplementation low molecular weight sodium alginate on growth, body composition, antioxidant enzymes, digestive and immune response in yellowfin sea bream juvenile ( Acanthopagrus latus ) were investigated. Fish (n=180) divided into 3 groups with replicates received treatments including basal diet without (control treatment), containing 5 g per...

Monthly fish samples were collected from one location at Shatt Al- Basrah Canal July 2008 to June 2009, using coastal seine net of dimensions 80 m length and 8 height with a mesh size 10×10 mm. Water temperature, salinity water transparency measured. Fishes identified in the laboratory total lengths weights Catch per unit effort was estimated for 22 species during sampling period. The biotic fa...

Yellowfin seabream, Acanthopagrus latus , is one of the most important species in terms stock enhancement China. However, using metagenomic techniques to explore feeding habits and stomach microbiome yellowfin seabream still rare. The objective this work was study sea bream from Daya Bay through analysis different weight classes (?50, 50–100, >100 g). Whole-metagenome shotgun sequencing ...

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...
