This book was released on 2014 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Boulder clusters were placed at three sites with small, homogeneous substrate in the Little Main Restigouche River in northern New Brunswick, Canada, in late summer 2005 to improve the rearing habitat for pre-smolt Atlantic salmon (Salmo salar). Population estimates were conducted at enhancement, control and reference sites between 2005-2007 prior to enhancement and for two years following enhancement to compare response of salmon parr. Age-2 parr density increased at enhancement sites following enhancement. During December 2005, a 25-year flood event and subsequent ice up and freshet in spring disturbed the study sites. A method was designed to interpret and rank boulder cluster stability degradation, and the data were compared with electrofishing estimates of abundance of salmon ages 0+, 1+ and 2+. Age 2+ parr abundance and biomass and age 1+ parr abundance were significantly higher at clusters ranked stable than at clusters ranked degraded."--Page ii.

This book was released on 1993 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.

Download or read book Atlantic Salmon Habitat Survey written by J. R. Semple and published by . This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dunbar Stream flows into the Nashwaak River, which then flows into the Saint John River at Fredericton. Salmon angling is considered good, but the increasing demand is nearing the point where supply is threatened. The habitat survey for Atlantic salmon was conducted from August 9-25, 1983, by walking the stream and recording water temperature, degree of shading, bottom composition, stream width and depth, and the extent of riffles, runs, flats, stills, and pools at intervals. Records were also kept of the numbers and kinds of potential predators of brook trout and juvenile Atlantic salmon and of complete and partial obstructions to migrating salmon. A quality classification for salmon parr nursery habitat was devised and spawning areas were classified also. This report presents the results of the survey.

Download or read book Salmonid Fisheries written by Paul Kemp and published by Wiley-Blackwell. This book was released on 2010-04-22 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmonid Fisheries is a landmark publication, concentrating on river management, habitat restoration and rehabilitation, disseminating lessons learnt in relation to the intensively studied salmonids that are applicable to future interventions, not just for salmonid species but for other non-salmonid species, biota and ecosystems. The contents of this book are the product of the Atlantic Salmon Trust’s 40th Anniversary Conference, held in association with the Game and Wildlife Conservation Trust. Drawing together carefully-edited contributions from many of the world leaders in river restoration from academia, commercial management and government agencies, this important book highlights the need to view river management from the context of the catchment and to adopt an ecosystem-based approach to restoration. The book is broadly divided into two sections which discuss first, the status of current understanding concerning the relationship between lotic habitat management, the response of salmonid fisheries and the theory of river restoration, and secondly, the application of this to habitat management and river restoration. Salmonid Fisheries is an extremely valuable work of reference for fisheries managers, ecologists, environmental scientists, fish biologists, conservation biologists and geomorphologists. Libraries in all universities and research establishments where biological and earth sciences, and fisheries management are studied or taught should have copies of this book on their shelves. Contributions from a wide range of well known experts Published in association with the Atlantic Salmon Trust Habitat management is crucial for dwindling wild salmon populations Of great importance to aquatic ecologists and fisheries managers
