Book excerpt: Excerpt from Variation in Salmonid Life Histories, Patterns and Perspectives Salmonid fishes differ in degree of anadromy, age of maturation, frequency of reproduction, body size and fecundity, sexual dimorphism, breeding season, morphology, and to a lesser degree, parental care. The advantages of large body size in reproductive competition probably favored the evolution of ocean foraging, and the advantages of safe breeding sites probably favored freshwater spawning. Both long-distance migrations and reproductive competition may have favored the evolution of semelparity. Reproductive competition has favored the evolution of secondary sexual characters, alternative mating tactics, and probably nest-defense behavior. Salmonids provide good examples of character divergence in response to ecological release and of parallel evolution. The great phenotypic plasticity of these fishes may facilitate speciation. Patterns of variation and the processes that generate them are valuable tools for foresighted management practices, predicting the outcomes of anthopogenic changes, managing to maintain biodiversity or particular populations of wildlife consumers, and maintaining the viability of fish populations.

Available in PDF, EPUB and Kindle. Book excerpt: Because of the huge natural variations in the abundance of salmon from year to year and place to place, much of the attention to these species has been prompted by an interest in reducing the variation and simultaneously maintaining or raising the mean abundance. In contrast, the importance of salmon and their relatives to the ecology of other species dependent on them and to the ecology of riparian ecosystems has scarcely been noticed. This review summarizes variation in salmonid life history, with an emphasis on the salmonine lineage, and suggests ecological, evolutionary, and management implications. Tables.

Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Book excerpt: Abstract : Over the last 150 years, many of the native migratory salmonid populations in North America have declined or been extirpated, and their native habitats have been significantly altered. Life history variation within and among migratory fish populations plays an important role in their persistence when faced with changing habitat conditions. One of the most extreme life history events in salmonids is the movement from lotic to lentic habitats, a migration that can span long distances and different habitat types. Understanding the factors affecting migratory life histories expressed by individuals within a population play an important role in dynamics and habitat requirements of the whole population. Here, I investigate three primary factors that contribute to an individual fishes' "decision" to migrate: genetics, environmental conditions, and individual body condition. In rainbow trout Oncorhynchus mykiss of the Shasta River, California we found distinct genetic structure among subpopulations in spatially separate habitats. Within one of those population segments we detected partial migration in which some individuals migrate, but others do not. We found that increased in daily mean water temperature were associated with upriver migration of adult coaster brook trout Salvelinus fontinalis in the Salmon Trout River, Michigan. In the Pilgrim River, Michigan we documented a previously unrecognized population of migratory brook trout. These results provide information critical to understanding the ecology of these at-risk populations and broaden our understanding of migratory behavior in general. The methodologies we developed to quantify movement data in the context of migratory life histories are applicable to other systems where further understanding of the drivers of migratory life history variation is needed.

Book excerpt: "Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have witnessed strong declines in fish stocks aroundthe globe, amid growing concerns about the impact of fisheries onmarine and freshwater biodiversity. Fisheries biologists andmanagers are therefore increasingly asking about aspects ofecology, behaviour, evolution and biodiversity that weretraditionally studied by people working in very separate fields.This has highlighted the need to work more closely together, inorder to help ensure future success both in management andconservation. The Handbook of Fish Biology and Fisheries has beenwritten by an international team of scientists and practitioners,to provide an overview of the biology of freshwater and marine fishspecies together with the science that supports fisheriesmanagement and conservation. This volume, subtitled Fish Biology, reviews a broadvariety of topics from evolutionary relationships and globalbiogeography to physiology, recruitment, life histories, genetics,foraging behaviour, reproductive behaviour and community ecology.The second volume, subtitled Fisheries, uses much of thisinformation in a wide-ranging review of fisheries biology,including methods of capture, marketing, economics, stockassessment, forecasting, ecosystem impacts and conservation. Together, these books present the state of the art in ourunderstanding of fish biology and fisheries and will serve asvaluable references for undergraduates and graduates looking for acomprehensive source on a wide variety of topics in fisheriesscience. They will also be useful to researchers who needup-to-date reviews of topics that impinge on their fields, anddecision makers who need to appreciate the scientific backgroundfor management and conservation of aquatic ecosystems.

Provides a unique overview of the study of fish biology andecology, and the assessment and management of fish populations andecosystems. The first volume concentrates on aspects of fish biology andecology, both at the individual and population levels, whilst thesecond volume addresses the assessment and management of fishpopulations and ecosystems. Written by an international team of expert scientists andpractitioners. An invaluable reference tool for both students, researchers andpractitioners working in the fields of fish biology andfisheries.

Book excerpt: With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.
