2012 reporting escapes for farmed fish

Information on escapes is collected by:

There are no marine net-pens in Quebec (QC) or Prince Edward Island (PEI).

The number of escapes is based on best estimates. Exact numbers are often difficult to obtain and can sometimes only be verified when fish are harvested.

The average size of fish is based on codes of containment and is a more accurate measurement than life stage.

The result refers to using recapture methods as detailed in the relevant code of containment and summarizes the results of the recapture attempt.

Date of escape information has been collected since 2011 in BC and since 2013 in the Atlantic provinces.
