Available in PDF, EPUB and Kindle. Book excerpt: "Within Canada, White Sturgeon occur only in British Columbia and are divided into six populations, based on geography, demographics and genetics: the lower, middle and upper Fraser River; Nechako River; Upper Columbia River; and, Kootenay River. All populations were assessed as Endangered by COSEWIC in 2003; the latter four are legally listed under the Species at Risk Act (SARA). This document is a SARA-compliant recovery strategy for the four SARA-listed populations, and also provides recovery and management recommendations for the lower and middle Fraser River populations. This amended recovery strategy corrects the omission of the Minister responsible for Parks Canada as a responsible minister for the Nechako River population (original publication date: 2014-03-19; amended: 2023-01-25). The critical habitat identified remains unchanged from the original recovery strategy"--Provided by publisher.

Download or read book Sturgeons and Paddlefish of North America written by G.T.O LeBreton and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

Available in PDF, EPUB and Kindle. Book excerpt: Canadian Environmental Philosophy is the first collection of essays to take up theoretical and practical issues in environmental philosophy today, from a Canadian perspective. The essays cover various subjects, including ecological nationalism, the legacy of Grey Owl, the meaning of “outside” to Canadians, the paradigm shift from mechanism to ecology in our understanding of nature, the meaning and significance of the Anthropocene, the challenges of biodiversity protection in Canada, the conservation status of crossbred species in the age of climate change, and the moral status of ecosystems. This wide range of topics is as diverse and challenging as the Canadian landscape itself. Given the extent of humanity's current impact on the biosphere – especially evident with anthropogenic climate change and the ongoing mass extinction – it has never been more urgent for us to confront these environmental challenges as Canadian citizens and citizens of the world. Canadian Environmental Philosophy galvanizes this conversation from the perspective of this place.

This book was released on 1987 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of their long life span and late age of maturity, white sturgeon may move extensively as juveniles or adults or both. More than 700 white sturgeon from several localities in the lower Fraser River were captured and tagged during May to September, 1985 to study their migration patterns, abundance, and rate of growth. This report summarizes, by month and locality, the number of sturgeon caught and tagged, the length and weight of each tagged sturgeon by date and locality of capture and release, and the recapture date and locality for all tagged sturgeon recovered in 1985.

Book excerpt: Around the world, human activities and climate change are altering ecosystems at unprecedented rates, which in many cases is outpacing our capacity to understand and predict the potential impacts on biodiversity. Fishing is one of the most pervasive anthropogenic stressors to fish populations worldwide, and so examination of fishing stressors is needed, especially in a changing climate. This thesis aimed to understand the physiological and behavioural consequences of catch-and-release (C&R) angling to white sturgeon, Acipenser transmontanus, in the lower Fraser River (LFR), British Columbia, Canada, with consideration of capture under different, seasonal river temperatures. White sturgeon are prized as a trophy species, with the largest individual sturgeon measuring more than 3 metres in length and putting up angling fight times of more than an hour. Currently, white sturgeon in the LFR are considered Threatened by the Committee on the Status of Endangered Wildlife in Canada. Despite conservation concerns, there are few regulations for the C&R fishery. Given the lack of restrictions, and knowledge that the Fraser River is warming due to climate change, I assessed the short- and long-term effects of C&R angling on white sturgeon in the LFR using physiological sampling of stress metabolites, a refined reflex impairment index, and acoustic telemetry. After angling wild sturgeon on the river, lactate concentrations were consistently higher in fish enduring long fight times, indicating anaerobic exhaustion. Here and in complimentary lab studies with captive sturgeon, reflex indicators of impairment were predicted by angling fight times and plasma lactate levels, and this effect was exacerbated in summer when temperatures are higher. Ultimately, recovery time from physical exhaustion increased with the duration of angling stress. Using tri-axial accelerometer acoustic transmitters, a snap-shot into the immediate post-release recovery behaviour of wild sturgeon revealed high inter-individual variability. Sturgeon required a recovery period after angling, which occurred consistently in nearshore environments. Long-term monitoring revealed high post-release survival (100%), indicating some resilience of sturgeon to angling, but there was some evidence of transient sublethal effects, and the fitness implications are still unknown. This is the most comprehensive examination of the impacts of recreational angling on a wild population of sturgeon. The results from this research revealed intriguing variance in the physiological and behavioural response of individual white sturgeon to C&R recreational angling, with some degree of environmental temperature dependence, and highlights the importance of understanding the drivers of such variation when managing fisheries.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation Physiology for the Anthropocene – A Systems Approach, Volume 39B in the Fish Physiology series, is a comprehensive synthesis related to the physiology of fish in the Anthropocene. This volume helps solve knowledge gaps by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to the management and conservation of fish and fisheries. Chapters in this release include Using physiology for recovering imperiled species – the Delta smelt, Conservation hatcheries – the Sturgeon story, Aquatic pollutants and stressors, and more. Other sections discuss Fisheries interactions in a multi-stressor world, Environmental change in riverine systems - Amazon basin stressors, Environmental change in lakes and wetlands – East African basin stressors, Coral reef fish in a multi-stressor world, Polar fish in a multi-stressor world, Physiology informs fisheries restoration and habitat management, A physiological perspective on fish passage and entrainment, Invasive species control and management – the sea lamprey story, and On the conservation physiology of fishes for tomorrow. Includes authoritative contributions from an international board of authors, each with extensive expertise in the conservation physiology of fish Provides the most up-to-date information on the ways in which different physiological systems are relevant to the management and conservation of fish and fisheries Presents the latest release in the Fish Physiology series Identifies how anthropogenic stressors perturb physiological systems Explores how different physiological systems can be exploited to solve conservation problems
