Description

Abstract: The project maintains high standards of quality in estimation of life history parameters, including accuracy, precision and efficiency from sample and data handling through age estimations and other life history analyses and data dissemination. Fish scales were collected and analyzed in various capacities in various locations and parts of ODFW from ca. 1950s/1960s – 1988. In about 1989, the Fish Life History Analysis Project began as the “Scale Analysis Project”, reading coho and Chinook salmon scales. In 1990 the project discerned between hatchery and wild spring Chinook via discriminant function analysis as part of the Lower Snake River Compensation Plan, which led to work with NOAA Fisheries on barged spring Chinook. The project stopped reading coho scales from spawning ground surveys in 2002 when fin clipping was well established in hatcheries. The current focus is primarily from 2 sources, coastal Chinook surveys and Willamette Chinook research. The remainder of the work comes from needs of various projects and district biologists. In 2012, the Scale Analysis Project was re-named the “Fish Life History Analysis Project”, which is a more appropriate name, given our expanding scope into other areas of fish life histories beyond scale analysis alone (e.g., otoliths).

Purpose: The purpose of this manual is to provide a background and context for other projects that work with the Fish Life History Analysis Project (FLHAP). Further information on scale analysis can be found in Clemens et al. 2013a and 2013b.
