Knowledge of fish ecology and its application to habitat management

Information on fish habitat in th-e lower Fraser River and estuary downstream from Agassiz is presented with emphasis on geophysical factors that may be affecting fish ecology. The application to fisheries management is considered. The lower Fraser River and estuary provides habitat to support over

50 species of fish. Brief synopses are given of the ecology of commercially and ecologically significant fish. Fish communities in Boundary Bay and on Roberts Bank tend to be dominated by species adapted to marine conditions. Some brackish-water species are found in the salt wedge and on Sturgeon Bank. Our knowledge of fish ecology in the lower Fraser River and estuary is based on a patchwork of studies. To enable good management of this world-class estuary into the twenty-first century, it is prudent for stakeholders to foster ongoing programs of integrated fisheries ecosystem research in this area.

Extent

Description: Fish habitats considered in this review extend from Agassiz, approximately 11 S km from the mouth of the Fraser River, to

the Strait of Georgia (Fig. 1), and include major tidal tributaries that enter the river in these reaches, as well as Sturgeon

and Roberts banks. Because many of the smaller tributaries drain the floodplain of the lower river, these habitats also are

mentioned.
