Fall index netting (FIN) is used by Alberta Environment and Parks to primarily monitor Walleye and Northern Pike populations. Fall index netting is being assessed as a method to assess the sustainability of other popular fisheries too,
for example, Lake Whitefish and Yellow Perch.
For more information on Alberta’s Fall Index Netting (FIN), please see Alberta’s FIN website:
The Fish Sustainability Index (FSI) was developed to bring consistency to fish stock assessments and provide a province-wide evaluation of the sustainability of Alberta fish species.
Information from fish stock assessments are translated into corresponding categories of risk to sustainability where a score of 1 represents a fishery at very high risk and a score of 4 or 5 represent low risk (Table 1).
