Summary of information relating to impacts of sea lice from fish farms on Scottish sea trout and salmon
Sea lice infest both farmed and wild salmonids to the potential detriment of aquaculture and angling interests. Several reviews have recently considered information concerning interactions between salmon farms and wild salmonids (e.g. Revie et al. 2009; Costello 2009; Whelan, 2010). Here, the evidence available to assess the likelihood and scale of impact of sea lice from salmon farms on Scotti...
متن کاملCommercial trials using emamectin benzoate to control sea lice Lepeophtheirus salmonis infestations in Atlantic salmon Salmo salar.
Two trials were conducted at commercial salmon farms to evaluate the efficacy of emamectin benzoate (Slice, 0.2% aquaculture pre-mix, Schering-Plough Animal Health) as a treatment for sea lice Lepeophtheirus salmonis (Krøyer) and Caligus elongatus Nordmann infestations in Atlantic salmon Salmo salar L. Trials were carried out in 15 m2 commercial sea pens, at temperatures of 5.5 to 7.5 degrees C...

متن کاملControl of sea lice on farmed Atlantic salmon S. salar L. with the oral treatment Emamectin benzoate (SLICE)
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 ...
متن کاملDetermination of emamectin benzoate in medicated fish feed.
A method was developed to quantitate emamectin benzoate in fish feed at levels between 5 and 15 ppm. The active ingredient is extracted from 20 g medicated feed into aqueous-methanolic solvent by overnight shaking. A solid-phase extraction procedure using a 2 g C18 cartridge is then used to concentrate the active residue and remove interfering matrix components. The extracted drug and internal ...
