Experimental Lakes Area (ELA) Projects
At the Experimental Lakes Area (ELA) near Kenora, Ontario, Fisheries and
Oceans Canada is conducting comprehensive scientific research to understand
the effects of freshwater net-cage aquaculture. The results will be used to
develop scientifically based guidelines for regulation of the freshwater
aquaculture industry and better understand how fish farms influence the
aquatic ecosystems they inhabit. The ELA, which comprises approximately 50
lakes, offer a natural "real world" laboratory setting. It is a unique facility that
has gained an international reputation as one of Canada's most innovative
and successful commitments to freshwater research.
Departmental researchers have established a small-scale fish farm in one of
the ELA lakes. Since 2003, some 10,000 rainbow trout fingerlings have been
placed in a cage each spring and fed commercially-produced feed pellets for
five to six months. Each fall, when the trout reach a mature weight of about
one kilogram, they are removed from the cage and harvested, as they would
be in actual fish farm operations. The lake ecosystem is closely monitored to
detect any fish farm-related changes with respect to the lake and to the
native species including lake trout. Fish behaviour is observed using
sophisticated electronic systems. The final results of this study can be
expected in two years time.
