Wild marine fish caught from a sea loch on the West Coast of Scotland were tested for infectious pancreatic necrosis virus (IPNV). One pool of 10 hake was found to be IPNV positive from 449 fish tested. This is believed to be the first isolation of IPNV made from hake caught in northern European waters. This was the only positive pool obtained from the study, illustrating a low prevalence of IP...

The aim of this study was to compare some biochemical blood parameters of rainbow trout (Oncorhynchus mykiss) living in running or still waters. Some biochemical parameters of rainbow trout were examined, and the results were evaluated between sampling locations and according to seasonal changes. Healthy adult rainbow trout were caught from six different locations on the Bahçelik Dam Lake and t...

Exposure to contaminants in fish may be associated with adverse health outcomes even as fish consumption is generally considered beneficial. Risk assessments conducted to support regulatory analyses rely on quantitative fish consumption estimates. Here we report the results of a national survey of high-frequency fish consumers (n = 2099) based on a survey population statistically representative...

The study was conducted in the river system located at Wilmar oil palm plantation Miri, Sarawak. objective of is to determine fish species diversity and composition streams rivers plantations. Fish were sampled using a variety fishing methods, including, scoop nets, cast net, gill nets different mesh sizes (1.0, 1.5, 2.0, 2.5, 3.75 4.0 cm) from 2 7 February 2014. A total 326 individual includin...

Sewage sludge dumped at Garroch Head in the Firth of Clyde contains significant quantities of chlorinated hydrocarbons, such as polychlorinated biphenyls (CBs). These compounds are lipophilic and resistant to degradation. They accumulate in the biota either from the water column or through the food chain, particularly in tissue with a high lipid content. Bottom dwelling fish, such as plaice, in...

The effect of cytochrome P4501A (CYP1A) induction on cell-specific benzo[a]pyrene (BaP) adduct formation was studied in rainbow trout (Oncorhynchus mykiss) gills. Fish preexposed to beta-naphthoflavone (betaNF) or caged in a polluted river were exposed to waterborne 3H-benzo[a]pyrene (3H-BaP). The 3H-benzo[a]pyrene adducts in the gill filaments were localized by autoradiography and CYP1A protei...

fungal infections of fish are widespread problem which affect wild and farmed species. the aim of the present study was to isolate and identify fungal flora in cultivated and natural caspian sea acipenser persicus. the samples were obtained from skin, fin and gill of the fish and were inoculated into culture media with antibiotics and incubated at 23±1 ?c. 13 species of fungi isolated from the ...

argulus foliaceus (crustacea: branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth. it causes pathological changes due to direct tissue dam­age and secondary infections. in the present study, lionhead goldfish (carassius auratus ), taken from...

the aim of this study was to investigate on obtained caviar quantity status of sturgeon at fishing grounds of the southwestern caspian sea. data of catches by means of fixed gill nets in sturgeon fish fishing grounds and beach seine were used during 5 years survey (2005-2009). a total of 1361 female sturgeon was caught including: 788 acipenser persicus, 410 a. stellatus, 60 a. guldenstaedti, 70...
