Aquatic total phosphorus (Tot-P) is measured at fish-cages in Lake Huron for environmental regulatory compliance. An improved understanding of how Tot-P is manifested in the near-field (<or=30 m) water column relative to reference sites within the same water body, current movement and farm structures is required to help interpret sample results and refine monitoring protocols where necessary. T...

The study's aim was to assess the robustness of farm-type anaerobic digestion with cattle slurry as main feedstock under change co-feedstock type and quality. Fish biomass, rainbow trout offal, potato, reindeer offal were investigated possible co-feedstocks in a 428-day semi-continuous reactor experiment. Using fish biomass or (19 % VS feed) produced an average 220 305 L CH 4 /kg compared 201 f...

The aetiological agent of infectious salmon anaemia (ISA) is an orthomyxo-like virus with a negativestranded RNA genome consisting of eight segments (Dannevig, Falk & Namork 1995; Falk, Namork, Rimstad, Mjaaland & Dannevig 1997; Mjaaland, Rimstad, Falk & Dannevig 1997). The ISA virus (ISAV) constitutes the only member of the Isavirus genus (Kawaoka, Cox, Haller, Hongo, Kaverin, Klenk, Lamb, McC...

the gamasiab river has one of the highest discharge in the western iran receiving wastewater of trout frames. the present study investigated effects of wastewater using bioassessment of benthic organisms. the benthos were sampled over four seasons using a surber sampler on four stations, upstream, on the farm outlet, 500 and 1000 m down the farm outlet. 5454 benthic fauna were identified that w...

Flavobacterium psychrophilum is the causative agent of Bacterial Cold Water Disease (BCWD)/ Rainbow Trout Fry Syndrome (RTFS) in rainbow trout Oncorhynchus mykiss. The disease associated with significant mortality farms and thereby responsible for severe economical losses this part aquaculture industry. Vaccination very young life cycle stages not successful due to immature development adaptive...
