Transport and dispersal of discharged sea lice chemical therapeutants in southwest New Brunswick
This project supplements the preliminary research conducted in southwest New Brunswick as part of a 2010-11 PARR project (PARR-2010-M-08) by extending research to additional locations and oceanography conditions.
Specific research objectives are to:
- complete analyses of existing and new field data;
- extend the locations to exposed areas such as the offshore areas of mainland southwest New Brunswick and Grand Manan; this work includes the collection of current meter, drifter, dye dispersal, photographs, hydrographic, wind and zooplankton data;
- extend the 2010 work on Salmosan® and AlphaMax® to include hydrogen peroxide;
- develop mathematical and numerical models that describe the discharge and subsequent dispersal from tarped cages and wellboats (i.e., dilution) and transport of the chemicals;
- evaluate the potential for non-target organisms to be exposed to the discharges; and
- evaluate the cumulative potential for environmental impacts associated with multiple treatments (i.e., multiple treatments on a farm and or at multiple farms).
