Evaluation of the environmental fate and biological effects of the anti-sea lice chemotherapeutant SLICE® - Phase-I

PARR-2008-P-14

Description

Sea lice infestation at marine cage finfish farms in British Columbia are most often treated by the application of the anti-parasitic chemotherapeutant SLICE® . Concerns regarding the potential effect and uptake of the active compound in this treatment, Emamectin benzoate (EB), by non-target organisms have been raised by numerous stakeholder groups. The project underway will examine:

  • the fate and concentration of EB and its desmethyl metabolite following the application of SLICE® at selected finfish farm sites in the surrounding environment. Measurements of concentrations in localized sediments and water column will be carried out to provide an assessment of the potential effect on ecosystem functioning and
  • the uptake of EB and its desmethyl metabolite by the Pacific Spot Prawn, Pandalus platyceros, under both laboratory and field conditions.

The overall findings of these studies will provide the most detailed and comprehensive assessment of the potential effects of the application of SLICE® at marine cage finfish farm locations on the surrounding benthic environment and resident prawn populations.
