The Vancouver Lamprey (aka the Cowichan Lamprey)

Did you know that we have a lamprey that lives in Cowichan and Mesachie lakes and nowhere else and it is considered to be critically imperilled?!! Due to some blundering in the fish naming ‘bureaucrazy’, our lamprey’s official name was shortened from the Vancouver Island lamprey to the Vancouver lamprey but Dr. Dick Beamish of DFO’s Nanaimo Biological Station is hoping that soon it will officially renamed the Cowichan lamprey. Dick is the scientist who originally identified the Cowichan lamprey as a separate species in the 1980’s.


Counting Fish with a Fence

By Rodger Hunter, Co-ordinator, Cowichan Watershed Board, October 19, 2010

The weather has turned in the watershed. On Thanksgiving weekend there is some serious rain. Things got very busy at the Department of Fisheries and Ocean’s counting fence that spans the Cowichan River below Allenby Road and above the Island Corridor railway bridge.

Fish in the Cowichan Watershed

FishSpeciesInCowichanWatershedThe Cowichan Watershed is home to many fish species. This is a function of both the size of the watershed and its incredible ecological richness as habitat and in terms of nutrients.

The ecological health of the watershed is reflected in the health of its fish. It's a mutual relationship. Healthy fish make a healthy watershed, and vice versa.

Click here for a table listing the fish in the Cowichan Watershed. The table shows fish presence recorded in a number of streams and three lakes in the watershed, and indicates whether they are exotic/introduced species, and shows their BC Conservation and COSEWIC status.

On this page we look at a few representative fish of the Cowichan Watershed, including some "Salmonids", which are the most abundant and ecologially and economically the most important fish, at "Exotic/Introduced" species, and a couple of "Rare or Endangered" fish.

"Anadromous" is the term used to describe fish which spend some part of their lives in fresh water and some in salt water. Salmon are anadromous.
