Aquaculture of the geoduck, Panopea generosaGould, 1850, has increased dramatically during the past decade in southern Puget Sound, WA, and the effects of these intertidal aquaculture geoduck beds on local fauna is mostly unknown. This study examined the species composition, relative abundances, and biodiversity indices of mobile benthic fauna in geoduck farm areas of southern Puget Sound. Surv...

Farming fish for human consumption continues to expand as an industry and, with this increasing interaction with captive fish populations, there is now a growing interest in determining how to create good welfare for the fish we farm. This article summarises recent advances in our understanding of pain and stress responses in fish and how these relate to farmed fish welfare. Over the last decad...

The use of orally administered emamectin benzoate (SLICE) to control sea lice was assessed for all stock on two salmon farms. Contrasting treatment regimes were used with two oral treatments in farm E in the second production year and one oral treatment in farm L with follow up with bath treatments. Emamectin benzoate surface coated on feed was administered as 50 ug kg1 fish biomass day-1 over ...

In March 2012, fishermen operating in a fjord in Northern Norway reported catching Atlantic cod, a native fish forming an economically important marine fishery in this region, with unusual prey in their stomachs. It was speculated that these could be Atlantic salmon, which is not typical prey for cod at this time of the year in the coastal zone. These observations were therefore reported to the...

Physical and chemical characteristics of the water column and sediments at sea bass/sea bream farm located on the middle Adriatic island of Brač were investigated during the 2001-2006 period. Measurements and samplings were performed at stations inside the farm area and at reference station, approximately 1 km distant from the farm. Investigated parameters in the water column were temperature, ...

an aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. in this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial tfc (thin film composite) polyamide nanofilter. the effects of ph (6.5-8.5), pressure (4-10 bar), concentration of to...

five common tetracycline resistance genes tet(a), tet(b), tet(m), tet(o) and tet(s) were studied by polymerase chain reaction in 100 bacteria isolated from iranian fish farms. in the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. nine isolates out of 46 aeromonas spp. contained either tet(a/m/s) resistant genes as follows: tet(a) in a. ...

this study evaluates the influence of yanã½klar creek on the water quality of fethiye gulf. accordingly, this study demonstrates (i) change in the water quality of fethiye gulf from 2006 to 2007; (ii) the water quality classification of the yanã½klar creek feeding fethiye gulf; and (iii) how land-based fish farm influences yanã½klar creek water quality in a fethiye-gã¶cek specially protected ar...
