Available in PDF, EPUB and Kindle. Book excerpt: Anders Halverson provides an exhaustively researched and grippingly rendered account of the rainbow trout and why it has become the most commonly stocked and controversial freshwater fish in the United States. Discovered in the remote waters of northern California, rainbow trout have been artificially propagated and distributed for more than 130 years by government officials eager to present Americans with an opportunity to get back to nature by going fishing. Proudly dubbed an entirely synthetic fish by fisheries managers, the rainbow trout has been introduced into every state and province in the United States and Canada and to every continent except Antarctica, often with devastating effects on the native fauna. Halverson examines the paradoxes and reveals a range of characters, from nineteenth-century boosters who believed rainbows could be the saviors of democracy to twenty-first-century biologists who now seek to eradicate them from waters around the globe. Ultimately, the story of the rainbow trout is the story of our relationship with the natural world--how it has changed and how it startlingly has not.

Download or read book Nonanadromous Life History Diversity of Rainbow Trout Oncorhynchus Mykiss written by Martin C. Arostegui and published by . This book was released on 2019 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainbow trout (Oncorhynchus mykiss) is a salmonid species, native to Pacific Ocean drainages in North America and eastern Russia, which exhibits fluvial (stream-resident), adfluvial (lake-migrant), and anadromous (ocean-migrant) ecotypes. The differentiation of fluvial and anadromous individuals in sympatry is well-studied, whereas comparatively little research has focused on the adfluvial form and its distinction from fluvial individuals in sympatry. Thus, the purpose of this dissertation was to investigate the ecological, genetic, and phenotypic diversity of nonanadromous rainbow trout in a natural stream-lake system to better understand the differentiation of fluvial and adfluvial individuals in sympatry, the basis of residency versus migration in this species, and the role of lakes in salmonid diversification. Rainbow trout were sampled in the lake (thus, by definition, adfluvial) and in several tributary streams (where adfluvial and fluvial individuals may co-occur), and were examined for a variety of features to develop a holistic understanding of the behavior, ecology, and evolution of these life history pathways. Stomach contents and stable isotopes revealed disparate trophic ecology among rainbow trout in connected stream and lake habitats, suggesting both an ontogenetic shift in the diet of adfluvial fish as well as divergence in diet between adfluvial and fluvial ecotypes. Rainbow trout in streams fed primarily on aquatic insects, while those in the lake largely consumed snails and amphipods; however, partial trophic convergence among trout in these two habitats occurred when they incorporated the marine nutrient subsidy of spawning sockeye salmon eggs. Stable isotope data suggested that the minimum size of migration from stream to lake habitat by adfluvial fish was ~150 mm fork length, suggesting a juvenile stream-rearing period of a year or more prior to lake entry. Dietary niche comparisons with sympatric Salvelinus species suggested a greater degree of dietary overlap between rainbow trout and Dolly Varden (S. malma) in streams than between rainbow trout and Arctic char (S. alpinus) in the lake, which may increase the relative fitness benefits of migration over residency for rainbow trout. Restriction site-associated DNA sequencing revealed an association between habitat type (stream or lake) and a chromosomal inversion in the rainbow trout genome as well as numerous single nucleotide polymorphisms, supporting the genetic divergence of adfluvial and fluvial ecotypes in sympatry. Rainbow trout in streams were nearly fixed for the rearranged haplotype of the Omy05 inversion, whereas trout in the lake exhibited a markedly higher frequency of the ancestral, anadromy-associated haplotype. The functions of outlier genes with nonsynonymous mutations among stream- and lake-caught trout paralleled those documented in studies of fluvial and anadromous O. mykiss, highlighting the migratory nature of the adfluvial ecotype even though it is nonanadromous. Structure was present at both non-outlier and outlier loci among and within streams supporting populations nearly fixed for the rearranged Omy05 haplotype (i.e., with a genetic predisposition for stream-residency), highlighting the roles of local adaptation and genetic drift via spatial isolation in population divergence. Assessment of lateral coloration patterns and multivariate analyses of body shape of rainbow trout from stream and lake habitats over a range of body sizes revealed ontogenetic and ecotypic variation in coloration and morphology. Color differences among trout of different size classes and habitats indicated ecotype-specific pathways resulting in different terminal coloration patterns; banded parr in streams transitioned to either a silver coloration suited to pelagic waters in the lake (when adfluvial) or bronze coloration suited to confined cover in streams (when fluvial). The morphology of lake-caught rainbow trout was distinct from that of stream-caught trout, and their morphological differentiation exhibited many shared but some unique patterns compared to sympatric Dolly Varden in streams and Arctic char in the lake. Patterns of morphological variation in rainbow trout among and within habitats suggested the presence of partial migration, in which both fluvial and adfluvial individuals are produced from the same population. A review of the spawning behaviors, rearing strategies, and trophic polymorphisms in lakes among 16 species of salmonids from the genera Oncorhynchus, Salmo, and Salvelinus identified a negative association between the extent of reliance on lakes and the degree of anadromy. Oncorhynchus exhibits the least lake reliance, Salmo an intermediate level, and Salvelinus the greatest; opposite of the anadromy spectrum identified in previous studies. Lakes support life history forms, reproductive ecotypes, and trophic morphs unique to lacustrine habitat, and also support anadromous and fluvial salmonids by providing spawning, rearing, overwintering, and/or summer refuge habitat. Adfluvial and anadromous salmonids exhibit similar migration-associated traits and behaviors including the parr-smolt transformation, sex-biased partial migration, and the presence of precocious 'jack' males.

Available in PDF, EPUB and Kindle. Book excerpt: This beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri. North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon. How this came to be, how they are related, and what makes them unique -- and so breathtaking -- is the story of Trout and Salmon of North America. The more than 100 illustrations of trout and salmon by Joseph Tomelleri showcased here exhibit a genius for detail, coloration, and proportion. Each portrait is made from field notes, streamside observations, photographs, and specimens collected by the artist. The result is a set of the most accurate and stunning illustrations of fish ever created. Robert Behnke has distilled 50 years of his research and writing about trout and salmon in completing this book. No one understands better than Behnke the diversity and conservation issues concerning these fishes or communicates so lucidly the biological wonders and complexities of their particular beauty. Also included are more than 40 richly detailed maps that clearly show the ranges of populations of trout and salmon throughout North America. An irresistible delight for anyone who appreciates natural history, Trout and Salmon of North America is a master guide to the natural elegance of our native fishes.

This book was released on 2014 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, I examine the influence of habitat gradients created by the 1980 eruption of Mount St. Helens, Washington USA on a recently established Rainbow Trout (Oncorhynchus mykiss) population in the Spirit Lake basin. My goal was to evaluate the responses of fish in seven streams across a volcanic disturbance gradient that included three major zones: Pyroclastic Flow (PF), Debris Avalanche (DA), and Blowdown Forest (BD). I compared fish habitat association and demography, sex ratios among age classes, and odds ratios of maturation to determine life-history responses. Age-1 maturing males were the most common life-history observed for non-young-of-year males across all fish-bearing streams. The propensity toward an early-maturing strategy seems to be mediated by two factors: one, stream resources limit residency (no fish older than age-2) and two, a strong relationship between length and maturity. Sex ratios for age-1 fish ranged in proportion from 100% male-biased in one of three fish-bearing PF streams, 65% male-biased (though not statistically different from 1:1) in one of two DA streams, to a roughly 1:1 ratio in all other streams. These results suggest that the disturbance gradient in the Spirit Lake basin may shift the ecological costs and benefits for sex-specific flexibility in life-history strategies across the landscape.

Available in PDF, EPUB and Kindle. Book excerpt: A look at the development of the sport over the past six centuries. Once limited to trout and salmon, today fly-fishing techniques are used to catch every fish species from minnows to marlin in rivers, lakes and oceans from the Amazon to the Arctic. From the many thousands of fly patterns developed over the centuries, The History of Fly-Fishing in Fifty Flies focuses on fifty iconic flies chosen to represent the evolution not only of fishing flies and fly tying but also the sport itself. Filled with illustrations and photographs of the flies (the fifty are just the starting point—more than 200 flies are mentioned or shown in the book), as well as profiles of key characters, The History of Fly-Fishing in Fifty Flies charts the growth and diversification of this fascinating sport from the fifteenth century to the present day and its spread from Britain, Europe and Japan to North and South America, Australia and New Zealand, and now to every country in the world. The evolution of fly-fishing tackle—rods, reels, lines and hooks—is also covered in a series of essays spread throughout the book. Praise for The History of Fly-Fishing in Fifty Flies “A delightful ramble along the stream of fishing history.” —Star Tribune “This glorious book of lures will get you itching for a new toy, a new boat, a new rod—anything to experience the relaxation of this old hobby.” —Foreword Reviews
Download or read book A Fish in Alien Streams written by Herjinder Singh Sahni and published by Hachette UK. This book was released on 2021-09-25 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE NEVER-BEFORE-TOLD STORY OF HOW THE TROUT CAME TO CALL INDIAN RIVERS ITS HOME. When the East India Company's business venture with India turned into a full-fledged occupation of the country, the British in India, apart from establishing their governance, were concerned with one more thing - how to make their surroundings here more akin to their homeland. Even as they dotted the Indian terrain with their manicured gardens, clock towers and pristine colonial structures, many among them (particularly a clutch of British anglers) increasingly felt the absence of one essential fish in Indian rivers - the trout. A Fish in Alien Streams presents the astounding story of a motley group of mavericks, adventurers and eccentric naturalists who, driven by their peculiar fixation, were obsessed with introducing the trout to India's rivers. This delightful account of an unknown slice of India's colonial past combines incredible research involving antique books, rare documents and letters of wistful longing for the trout with the minutiae of fishing and skilful planning. Spanning the Kashmir valley, Kullu, Uttarkashi, the Nilgiris, Travancore and Ceylon (now Sri Lanka), this unique and incredible tale is about magnificent passions, countless failures and ultimate triumph.
