Available in PDF, EPUB and Kindle. Book excerpt: Many species of fish occupying inland waters reside in watershedsthat were or still are surrounded by forests and are dependent inmajor ways upon such cover. The interactions between fishes andforests are complex, multifaceted, dynamic processes involving mostinland surface waters, forests, subsurface waters, geology andsoils, climate and its changes, and the biotic components of therelevant ecosystems. These interactions also include the aspects offorestry tied to human development, economics, population growthand even philosophies. Fishes and Forestry is truly a landmark publication. Theeditors, Professors Northcote and Hartman, have drawn together andcarefully edited chapters written by 56 scientists from around theworld, covering a vast wealth of information never before appearingwithin the covers of one book. Following an introductory chapter,this exceptional work is broadly divided into sections covering:the ecology of forests, streams, lakes and estuaries; fish biologyand ecology; forestry activities and their effects on aquaticsystems and fishes; 14 chapters covering examples of fish-forestryinteractions from around the world and a final section coveringmeans of effecting better fish-forestry interactions. Fishes and Forestry is an essential purchase for allthose involved in inland fisheries, forestry and their interaction,including fisheries scientists, fish biologists, ecologists,environmental scientists and forestry scientists. Libraries in alluniversities and research establishments where these subjects arestudied and taught should have several copies on their shelves.
Download or read book Temperature Preference and Distribution of Juvenile Arctic Grayling Thymallus Arcticus in the Williston Watershed British Columbia Canada written by Sarah C. F. Hawkshaw and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The habitat requirements of juvenile Arctic grayling (Thymallus arcticus) were assessed in the Williston watershed, British Columbia, where the population is currently red-listed (critically imperiled). Temperature preferences of juvenile Arctic grayling was assessed behaviorally using a shuttlebox system, and an information theoretic approach analysis of logistic regression models was used to evaluate the influence of environmental factors on the distribution of juvenile Arctic grayling throughout the Williston watershed. Temperature preference of juvenile Arctic grayling did not vary between the two tributaries in the watershed (p = 0.77) and the average preferred temperature was 16.84 ± 0.66 °C (n = 28). Comparisons of the preferred temperature to ambient water temperatures suggested that juvenile Arctic grayling will avoid areas where maximum water temperature is above the preferred temperature. There was a positive association between juvenile Arctic grayling occurrence and stream order (SO) and stream order multiplied by distance from the Williston reservoir (SDRxSO), as well as a negative association with the mean daily water temperature variance (varT) and average water temperature (aveT). Overall these findings suggest that large river systems are important juvenile Arctic grayling habitat and management decision should be made to ensure protection of this habitat throughout the range of this species."--P. ii.

Download or read book A Strategic Plan for the Conservation and Restoration of Arctic Grayling in the Williston Reservoir Watershed written by and published by . This book was released on 2001 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic grayling were abundant in the upper Peace, Finlay, & Parsnip watersheds of British Columbia before construction of the Bennett Dam and flooding of the Williston Reservoir in 1968. Arctic grayling populations in the Reservoir started to decline in the 1980s and by 1988 most populations in the Reservoir & smaller streams flowing directly into the reservoir had severely declined or disappeared. This document presents a plan that intends to provide a co-ordinated approach to preserve & restore Arctic grayling populations and their habitat within the Williston watershed. The introduction reviews the biology of this species and the possible reasons for the decline in its population. Plan activities are then listed under four strategic objectives: understanding Arctic grayling biology; develop watershed-specific management strategies to conserve & restore native stocks; protect, restore, & manage Arctic grayling habitat; and inform & educate the public. A work plan & time lines are also included.

Download or read book An Information Summary on Arctic Grayling from the Williston Reservoir Watershed with Data Gap Analysis and Recommendations written by and published by . This book was released on 2002 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication summarizes information on Arctic grayling in the Williston Reservoir watershed of British Columbia. It begins with a chronological outline of Arctic grayling research in the watershed including inventories, stream fertilization, habitat enhancement, stocking, life history & genetic studies, and radio tracking. It then provides a synthesis in outline form of Arctic grayling data from Williston watershed projects & from the published literature under the following headings: reproduction, early rearing, habitat utilization, migrations, food, age & growth, and genetics. This is followed by discussion of the potential factors that limit the Arctic grayling population in the Reservoir, such as food & habitat availability, predation, egg & fry mortalities, competition, and overfishing. Finally, recommendations are made to prevent further declines in the Arctic grayling population, enhance or restore production from existing populations, and determine if & how stocks can be reintroduced into historical habitats.

This book was released on 2002 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes & presents results of a field program carried out in 2000 on rivers in the Williston Reservoir watershed of British Columbia to gather information on Arctic grayling. The program included beach seine sampling of grayling juveniles along the Parsnip River and underwater counts at index sites along the Table & Anzac rivers to obtain estimates of grayling adults. Results related to the distribution & relative abundance of Arctic grayling are compared to those of a similar program conducted in 1998.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes a 1998 study of Arctic grayling life history & habitat utilization on three rivers in the Williston Reservoir watershed of British Columbia. Introductory sections describe the study area (the Table River, Anzac River, and the 25-kilometre section of the Parsnip River between the Table & Anzac rivers) and methodology. The research included collection of water temperature data, an egg deposition survey, fry distribution surveys, sampling of young of the year, sampling of suitable habitats, mark recapture studies, and collection of biological information from sampled grayling. Results are presented & discussed with regard to water temperature trends, abundance & distribution of grayling fry, fish density, habitat utilization, characteristics of suitable habitats, abundance of adult grayling & other sport fish (trout, whitefish), age class distribution of grayling, and juvenile growth rates. Based on the findings, management implications & research needs are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: As part of ongoing investigations to determine the status of Arctic grayling in the Williston watershed in northern British Columbia, a large tributary stream of the Williston Reservoir was examined to determine Arctic grayling distribution, relative abundance, and habitat use. This report presents findings of electrofishing surveys that looked for the presence of Arctic grayling in the Ingenika River watershed. Observations of grayling fry habitat use are compared to studies conducted on other rivers in the Williston watershed. Results are also presented from angling surveys that collected information on adult grayling distribution.
