Fish Sampling in the Multnomah Channel Marsh Natural Area near Portland Oregon from 2014-03-24 to 2015-07-15

Description

The Multnomah Channel Wetland Restoration Monitoring Project characterizes wetlands use by juvenile salmonids and other fishes in the Multnomah Channel Marsh Natural Area (MCMNA) and nearby habitats of the Columbia River estuary. The project is a collaborative program by federal, state, and municipal organizations evaluating the ecological effectiveness of floodplain restoration actions at the MCMNA on behalf of at-risk juvenile salmonids. The project uses a wide range of sampling methods to document fish, invertebrate prey, vegetation, and physical habitat conditions and to experimentally assess salmon performance. Sampling methods include: PIT arrays and remote detection systems to monitor salmon access, residency, and movements to and from the wetland; experimental net pens to compare salmon food and relative growth potential within different vegetation types; beach seines, traps, PIT detectors, electro-shockers, and other gear to monitor fish abundance and salmon stock composition; and benthic cores, insect fallout traps, emergent traps, and neuston nets to determine invertebrate prey composition, abundance, and transport from the wetland site. Fish samples are also collected along the main-stem estuary, Multnomah Channel, and other wetlands to investigate the effects of river flow and water elevation on fish access to the MCMNA. Invertebrate and fish stomach samples are analyzed at the main campus of Oregon State University (Corvallis, OR) and at the Oregon Department of Fish and Wildlife Corvallis Research Laboratory. Other activities, vessels, and sampling equipment are staged from the Pt. Adams Research Station in Hammond, OR. Species abundance, length, weight, residence time data for juvenile salmon in main stem Columbia R, Multnomah Channel. Mark and recapture data.
