Available in PDF, EPUB and Kindle. Book excerpt: "The Washington Department of Fish and Wildlife (WDFW) installed an eight-foot diameter rotary screw trap in the Nisqually River at river mile 12.8, near the Centralia City Light Yelm Hydro Powerhouse in 2009 to monitor outmigrating juvenile salmonids. The primary objectives of this study were to estimate abundance and document total catch, run timing, size and age composition of outmigrating juvenile Chinook salmon and steelhead. Our secondary objectives were to (a) estimate the abundance of juvenile Coho, Chum and Pink salmon; (b) document total catch, run timing, size and age composition of outmigrating of juvenile Coho, Chum, and Pink salmon; and (c) document species and total catch of non-target fish captured in the trap. Information collected at the Nisqually River rotary screw trap monitoring project provides critical abundance and life history information for the salmon and steelhead stocks within the river. These data coupled with adult return data can be used to measure key survival and productivity metrics to assess management practices and evaluate recovery efforts. This report describes the results of the monitoring efforts during the 2009-2015 field seasons."--From abstract.

Bryant and published by . This book was released on 2008 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe a protocol to monitor the effectiveness of the Tongass Land Management Plan (TLMP) management standards for maintaining fish habitat. The protocol uses juvenile coho salmon (Oncorhynchus kisutch) in small tributary streams in forested watersheds. We used a 3-year pilot study to develop detailed methods to estimate juvenile salmonid populations, measure habitat, and quantitatively determine trends in juvenile coho salmon abundance over 10 years. Coho salmon have been shown to be sensitive to habitat alterations, and we use coho salmon parr as the primary indicator in the protocol. A priori criteria for type I and type II error rates, effect size, and sample sizes for the protocol were derived with estimates of variance computed from the 3-year pilot study. The protocol is designed to detect trends in abundance of coho salmon parr, as well as coho salmon fry and Dolly Varden (Salvelinus malma), in small streams managed according to TLMP standards and guidelines and to compare these to trends in unmanaged (old-growth) watersheds. Trends are adjusted to account for statistically significant habitat covariates. This information provides an important element in monitoring land management practices in the Tongass National Forest. The methods we describe may have application to monitoring protocols elsewhere for fish populations and land management practices.

Download or read book Juvenile Chinook Salmon Life History Variation written by Bryce N. Oldemeyer and published by . This book was released on 2015 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last century, wild populations of salmonids in the Columbia River basin have significantly declined. Several of these populations have been listed as "threatened" under the Endangered Species Act and collaborative multi-state, multi-agency efforts have been established to manage and restore at-risk populations. A thorough understanding of a species' life history is necessary for effective conservation. A tool widely implemented to collect information during juvenile salmonid life stages is a rotary screw trap. Rotary screw traps sample juvenile salmonids as they migrate to the ocean but environmental conditions, low species abundances, and complex life histories can lead to sparse data. In this study I implemented a hierarchical Bayesian model to obtain abundance estimates from rotary screw traps with large periods of missing data and utilized this information to explore two predominant life history assemblages of juvenile Chinook salmon that have strong implications on survival and reproductive success.

Book excerpt: "This report describes a study in the spring of 1983 to monitor the presence of juvenile salmonids along the Duwamish waterway and Elliott Bay shorelines. The initial objective of the survey was to assess the arrival of juvenile salmonids in the vicinity of the Terminal 20 construction project. Pile driving activities at Terminal 20 were to continue in March and early April only until juvenile salmonids appeared along the shorelines... A second more general objective of the study was to document the timing and distribution of the juvenile salmonids throughout the Duwamish waterway and Elliott Bay during the spring migration period."--Introd.

This book was released on 2005 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reviews existing and proposed protocols used to monitor stream ecosystem conditions and responses to land management activities in the Pacific Northwest. Because of recent work aimed at improving the utility of habitat survey and fish abundance assessment methods, this review focuses on current (since 1993) monitoring efforts that assess stream habitat conditions and juvenile fish use. It does not focus on protocols specifically intended to monitor trends in fish populations for salmon recovery efforts, other fish life-history stages (e.g., salmonid smolt monitoring or spawner surveys), or approaches designed to monitor water quality or sources of pollution. We provide an overview of agency monitoring protocols, adaptive management, and types of monitoring, and briefly review the core habitat characteristics thought to be most sensitive to forest management practices. Finally, we summarize a selection of protocols in use in the Pacific Northwest in light of those core habitat characteristics.
