Description

Abstract: Monitoring the status of salmonids in Oregon coastal streams is an important component of the Oregon Department of Fish and Wildlife’s (ODFW’s) contribution to the Oregon Plan for Salmon and Watersheds. Since 1998, ODFW has implemented a probabilistic sampling design (Stevens 2002) to monitor adult and juvenile coho in Oregon coastal streams, and in 2002, ODFW expanded its monitoring program to include juvenile steelhead.

Purpose: The objective of the study is to evaluate juvenile fish survey methodology as a monitoring tool at the basin scale. This report will: 1) summarize juvenile salmonid data collected by two methods (snorkeling and electrofishing) at shared sites in the Smith River basin during the summer of 2004, and 2) provide a comparative analysis of several years data of how the two juvenile survey methods and the adult EMAP spawner surveys correspond to mark recapture estimates of adult fish passing above Smith River Falls.
