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.
Download or read book Assessing Survival of Mid Columbia River Released Juvenile Salmonids at McNary Dam Washington 2008 09 written by U.S. Department of the Interior and published by CreateSpace. This book was released on 2014-03-30 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few studies have evaluated survival of juvenile salmon over long river reaches in the Columbia River and information regarding the survival of sockeye salmon at lower Columbia River dams is lacking. To address these information gaps, the U.S. Geological Survey was contracted by the U.S. Army Corps of Engineers to evaluate the possibility of using tagged fish released in the Mid-Columbia River to assess passage and survival at and downstream of McNary Dam. Using the acoustic telemetry systems already in place for a passage and survival study at McNary Dam, fish released from the tailraces of Wells, Rocky Reach, Rock Island, Wanapum, and Priest Rapids Dams were detected at McNary Dam and at the subsequent downstream arrays. These data were used to generate route-specific survival probabilities using single-release models from fish released in the Mid-Columbia River.
Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.

This book was released on 2004 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year of 2002 represented the eighth year of a multi-year project, monitoring the outmigration and survival of juvenile salmonids in the lower Umatilla River. This project both supplements and complements various ongoing and completed work within the Umatilla River basin. Knowledge gained on juvenile outmigration and survival assists researchers and managers in adapting hatchery practices, flow enhancement strategies, canal and fish ladder operations, and supplementation and enhancement efforts of natural and restored fish populations. Findings from this study also assist in assessment of the success of upriver habitat improvement projects and provide an overall evaluation of the Umatilla River fisheries restoration program. General project objectives include: Evaluation of the outmigration and survival of natural and hatchery juvenile salmonids in the lower Umatilla River, in an effort to enhance the understanding of migration characteristics, survival bottlenecks, species interactions and effects of management strategies. Specific objectives for 2002 included: (1) Operation of the remote interrogation system at Three Mile Falls Dam, West Extension Canal; (2) Design of improved PIT tag detection capabilities at Three Mile Falls Dam east bank adult fish ladder; (3) Estimates of migrant abundance, migration timing and in-basin survival of tagged juvenile salmonids representing various hatchery, rearing, acclimation and release strategies; (4) Monitoring of abundance and trends in natural production of salmon, steelhead and pacific lamprey; (5) Continuation of transport evaluation studies to evaluate the relative survival between transported and nontransported fish; (6) Assessment of the condition, health, size, growth and smolt status of hatchery and natural migrants; (7) Investigation of the effects of canal and fishway operations and environmental conditions on fish migration and survival; (8) Documentation of temporal distribution and diversity of resident fish species; and (9) Participation in planning and coordination activities within the basin and dissemination of results. Key findings for 2002 revealed: (1) Migrant abundance of natural fish was roughly 10% that of hatchery produced fish; (2) An undetermined number of hatchery summer steelhead are residualizing in the upper Umatilla basin and potentially overwintering and migrating out as 2 year old smolts; (3) Transported fish may have a survival advantage over non-transported fish; (4) The later release of hatchery summer steelhead resulted in emigration timing that differed from that of naturally-produced fish; (5) Large-grade summer steelhead released lower in the river displayed improved survival over fish released higher; (6) Extended reared steelhead did not exhibit a survival advantage over standard reared fish; (7) Second year evaluation following reduction in the subyearling fall chinook program revealed survival to be similar to pre-reduction estimates; (8) Migration success was not improved nor in-river residence time reduced by acclimation of coho salmon at RM 56; (9) Early released spring chinook salmon migration and survival was unable to be evaluated due downstream monitoring facilities being in-operable during the early migration.

This book was released on 2003 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the seventh year of a multi-year project, monitoring the outmigration and survival of juvenile salmonids in the lower Umatilla River. This project both supplements and complements ongoing and completed work within the Umatilla River basin. Knowledge gained on juvenile outmigration and survival assists researchers and managers in adapting hatchery practices, flow enhancement strategies, canal and fish ladder operations, and supplementation and enhancement efforts of natural and restored fish populations. Findings from this study also measure the success of upriver habitat improvement projects and provide an overall evaluation of the Umatilla River fisheries restoration program. The general objectives for 2001 were to: (1) Estimate migrant abundance and survival and determine migration parameters of PIT-tagged hatchery and natural juvenile salmonids; (2) Monitor natural production and estimate overall abundance of pacific lamprey, chinook and coho salmon and summer steelhead; (3) Assess the condition and health of migrants and determine length-frequency distributions through time; (4) Investigate the effects of canal and fishway operations and environmental conditions on fish migration and survival; (5) Investigate and implement improved tag monitoring capabilities; and (6) Participate in planning and coordination activities within the basin and disseminate results. More specifically, 2001 objectives included the ongoing evaluation of migrant abundance and survival of tagged hatchery fish groups from various species-specific hatchery, rearing, acclimation and release strategies; fourth year reach survival results; continuation of transport evaluation studies; outmigrant monitoring and estimation of natural abundance, and further investigation of the effects of canal operations, environmental factors, fish condition and health on migration, abundance and survival. Some of the key findings for 2001 are: (1) A significant decline in outmigrant abundance of natural salmonids compared with the upward trend of previous years; (2) An undetermined number of hatchery summer steelhead are overwintering in the Umatilla River and migrating out as 2-year old smolts; (3) Transported fish may have a survival advantage over non-transported fish; (4) Migrant survival of fish from the Little White, Carson and Herman Creek hatcheries may have been influenced by disease in 2001; (5) Acclimation may benefit migrant survival of subyearling fall chinook; (6) Overwintering of spring chinook in acclimation ponds may not provide a survival advantage over standard-acclimated fish; and (7) Fish sampled in 2001 tended to be descaled and injured at a higher rate compared with previous years.

This book was released on 2007 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes activities conducted by the Oregon Department of Fish and Wildlife's Juvenile Outmigration and Survival M & E project in the Umatilla River subbasin between 2004-2006. Information is used to make informed decisions on hatchery effectiveness, natural production success, passage improvement and flow enhancement strategies. Data collected includes annual estimates of smolt abundance, migration timing, and survival, life history characteristics and productivity status and trends for spring and fall Chinook salmon, coho salmon and summer steelhead. Productivity data provided is the key subbasin scale measure of the effectiveness of salmon and steelhead restoration actions in the Umatilla River. Information is also used for regional planning and recovery efforts of Mid-Columbia River (MCR) ESA-listed summer steelhead. Monitoring is conducted via smolt trapping and PIT-tag interrogation at Three Mile Falls Dam. The Umatilla Juvenile Outmigration and Survival Project was established in 1994 to evaluate the success of management actions and fisheries restoration efforts in the Umatilla River Basin. Project objectives for the 2004-2006 period were to: (1) operate the PIT tag detection system at Three Mile Falls Dam (TMFD), (2) enhance provisional PIT-tag interrogation equipment at the east bank adult fish ladder, (3) monitor the migration timing, abundance and survival of naturally-produced juvenile salmonids and trends in natural production, (4) determine migration parameters and survival of hatchery-produced fish representing various rearing, acclimation and release strategies, (5) evaluate the relative survival between transported and non-transported fish, (6) monitor juvenile life history characteristics and evaluate trends over time, (7) investigate the effects of river, canal, fishway operations and environmental conditions on smolt migration and survival, (8) document the temporal distribution and diversity of resident fish species, and (9) participate in planning and coordination activities within the basin and dissemination of results.

Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by OUP Oxford. This book was released on 2010-01-08 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Download or read book Assembly Rules and Restoration Ecology written by Vicky M. Temperton and published by Island Press. This book was released on 2013-04-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how ecosystems are assembled -- how the species that make up a particular biological community arrive in an area, survive, and interact with other species -- is key to successfully restoring degraded ecosystems. Yet little attention has been paid to the idea of assembly rules in ecological restoration, in both the scientific literature and in on-the-ground restoration efforts. Assembly Rules and Restoration Ecology, edited by Vicky M. Temperton, Richard J. Hobbs, Tim Nuttle, and Stefan Halle, addresses that shortcoming, offering an introduction, overview, and synthesis of the potential role of assembly rules theory in restoration ecology. It brings together information and ideas relating to ecosystem assembly in a restoration context, and includes material from a wide geographic range and a variety of perspectives. Assembly Rules and Restoration Ecology contributes new knowledge and ideas to the subjects of assembly rules and restoration ecology and represents an important summary of the current status of an emerging field. It combines theoretical and practical aspects of restoration, making it a vital compendium of information and ideas for restoration ecologists, professionals, and practitioners.
