Indian major carp, Cirrhinus cirrhosus was considered to monitor culture and health status in farm condition from Bhaluka and Muktagacha of Mymensingh region of Bangladesh for a period of seven months starting from September, 2010 to March, 2011. Monthly sampling was carried out for growth and health condition. Samples of skin and muscle, gill, liver and kidney were observed by clinical and his...

abstract environmental factors including salinity and temperature can affect the physiology and performance of the growth of fish, so many of internal organs such as gill may be showed wide range of morphological and functional changes. fingerling common carp were exposed for 21 days in groups at 20, 25 and 30°c and three salinity levels 0, 5 and 10ppt. histological changes of gills tissue of c...

The influence of dissolved oxygen concentration on gill histopathology of great sturgeon (Huso huso) was evaluated in two weight classes (initial weight 280.9?49.2 g and 1217.9?138.1 g respectively). Oxygen treatments included hypoxia (2-3 mg/l), normoxia (5-6 mg/l) and hyperoxia (9-10 mg/l). The fish were acclimated to experimental tanks for one week then randomly distributed into 9 tanks i...

the aim of this study was measuring the amount of heavy metals (nickel, cobalt, cadmium, chromium and zinc) in different tissues of black fish (capoeta fusca). for this reason, in july 2010, 24 black fish was caught at the central part qanats of birjand. the results showed that between the whole length and the weight of fish and concentration of heavy metals in different observed tissues there ...

Background: Fish have been at high risk of atrazine toxicity. Comparative atrazine toxicity on the tissues of Clarias gariepinus is scanty. Therefore, acute and chronic effects of atrazine on some biochemical parameters in Clarias gariepinus were investigated in this study. Methods: Atrazine toxicity was determined by assessing the responses of glucose, protein, alanine aminotransferase (ALT...

kol river drains into the persian gulf and its watershed encompasses  areas  in  hormozgan, kerman and fars provinces. identification of fish species of the river was conducted seasonally from summer to winter 2005. we selected 8 sampling stations based on the height of  sea  level  from branches of kol river near estuary. totally, 160 specimens were caught with gillnet, cast net and hook. we i...

parasitic infection of pampus argenteus was examined from northwest of qeshm island. a total of 62 specimens were caught in summer 2008 and winter 2009 by bottom trawl and the specimens were selected randomly in different length classes and immediately deep frozen. all samples were transferred to laboratory, after measuring fish weight and length, parasitological survey implemented by stereo an...

Ichthyozoonotic Mycobacterium spp. poses health risks both to fish and humans. In this study, the presence of ichthyozoonotic Mycobacterium spp. was investigated in red mullet (Mullus barbatus barbatus) and surmullet (Mullus surmuletus), widely caught species in the Mediterranean and the Aegean Sea. A total of 208 fish samples, provided from fishermen of Mersin province (Turkey) were studied. U...

Lake Winnipeg, Manitoba, is Canada’s second largest commercial inland freshwater fishery, and concern over collapse of the walleye fishery growing. Molecular techniques have been increasingly used to study responses wild organisms environmental anthropogenic stressors. The present transcriptomics examine physiology wild-caught ( Sander vitreus (Mitchell, 1818)) across Winnipeg using non-lethal ...
