Scaling Salmonid Life History by Habitat Area: A Conceptual Approach to Estimating Estuarine Conservation Needs
Methods to define the critical estuarine habitats ofsalmon are needed to support conservation initiatives and species recovery strategies. In this paper, we describe aconceptual approach that might be useful for this task. Growth rates and estimates offood consumption for ocean-type Chinook salmon Oncorhnychm tshaioytscha rearing in four estuaries (Squamish River estuary, Nanaimo River estuary, Campbell River estuary, and Fraser River estuary) discharging into the Strait ofGeorgia, British Columbia, Canada, were compiled using literature data and abioenergetic model. Consumption data were then scaled according the areal extent offour habitats (open water, sand flats, marsh, and riparian) often used as surrogates for fish food production. We documented between-estuary variations in the scaled consumption data, possibly related to inter-estuary differences in habitat quantity, quality, or population-specific growth. Further analysis, calibration, and verification are needed before implementation ofthe concept.

Wiens (1989) recommended that habitat ecologists should begin searching for consistent patterns in scaling effects instead of asking how results vary as a function of scale. More empirical data are clearly needed to build a body of knowledge about habitat scales, especially those relevant to fish,
and we hope our contribution will be a useful contribution to that database.
