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.

"Suppose that, more than a century ago, U.S. government officials became concerned that democracy itself was at risk because men seemed to be less virile. And to reverse this trend they decided to populate streams, rivers, and lakes with "an entirely 'synthetic' fish" - quarry that would allow Americans to rediscover their abilities to capture and kill animals. And suppose that, up to the present, these creatures were still being produced and distributed on a massive scale, sometimes even being trained like gladiators and pumped full of the same supplements as professional athletes so they would provide a better fight." "Such is the true story of the rainbow trout. Sometimes vilified for their devastating effects on native fauna, sometimes glorified as the preeminent sport fish, the rainbow trout is the repository of more than a century of America's often contradictory philosophies about the natural world. This book chronicles the discovery of rainbow trout, their artificial propagation and distribution, and why they are being eradicated in some waters yet are still the most commonly stocked fish in the United States." --Résumé de l'éditeur.

From beer labels to literary classics like A River Runs Through It, trout fishing is a beloved feature of the iconography of the American West. But as Jen Brown demonstrates in Trout Culture: How Fly Fishing Forever Changed the Rocky Mountain West, the popular conception of Rocky Mountain trout fishing as a quintessential experience of communion with nature belies the sport’s long history of environmental manipulation, engineering, and, ultimately, transformation. A fly-fishing enthusiast herself, Brown places the rise of recreational trout fishing in a local and global context. Globally, she shows how the European sport of fly-fishing came to be a defining, tourist-attracting feature of the expanding 19th-century American West. Locally, she traces the way that the burgeoning fly-fishing tourist industry shaped the environmental, economic, and social development of the Western United States: introducing and stocking favored fish species, eradicating the less favored native “trash fish,” changing the courses of waterways, and leading to conflicts with Native Americans’ fishing and territorial rights. Through this analysis, Brown demonstrates that the majestic trout streams often considered a timeless feature of the American West are in fact the product of countless human interventions adding up to a profound manipulation of the Rocky Mountain environment. https://www.youtube.com/watch?v=ZKMwEkKj9jg

A significant number of the world's ocean fisheries are depleted, and some have collapsed, from overfishing. Although many of the same fishermen who are causing these declines stand to suffer the most from them, they continue to overfish. Why is this happening? What can be done to solve the problem. The authors of Fish, Markets, and Fishermen argue that the reasons are primarily economic, and that overfishing is an inevitable consequence of the current sets of incentives facing ocean fishermen. This volume illuminates these incentives as they operate both in the aggregate and at the level of day-to-day decision-making by vessel skippers. The authors provide a primer on fish population biology and the economics of fisheries under various access regimes, and use that information in analyzing policies for managing fisheries. The book: provides a concise statistical overview of the world's fisheries documents the decline of fisheries worldwide gives the reader a clear understanding of the economics and population biology of fish examines the management issues associated with regulating fisheries offers case studies of fisheries under different management regimes examines and compares the consequences of various regimes and considers the implications for policy making The decline of the world's ocean fisheries is of enormous worldwide significance, from both economic and environmental perspectives. This book clearly explains for the nonspecialist the complicated problem of overfishing. It represents a basic resource for fishery managers and others-fishers, policymakers, conservationists, the fish consuming public, students, and researchers-concerned with the dynamics of fisheries and their sustenance.

Modern-day fly fishing, like much in life, has become exceedingly complex, with high-tech gear, a confusing array of flies and terminal tackle, accompanied by high-priced fishing guides. This book reveals that the best way to catch trout is simply, with a rod and a fly and not much else. The wisdom in this book comes from a simpler time, when the premise was: the more you know, the less you need. It teaches the reader how to discover where the fish are, at what depth, and what they are feeding on. Then it describes the techniques needed to present a fly at that depth, make it look lifelike, and hook the fish. With chapters on wet flies, nymphs, and dry flies, its authors employ both the tenkara rod as well as regular fly fishing gear to cover all the bases. Illustrated by renowned fish artist James Prosek, with inspiring photographs and stories throughout, Simple Fly Fishing reveals the secrets and the soul of this captivating sport.

An eye-opening introduction to the complexity, wonder, and vital roles of coral reefs When mass coral bleaching and die-offs were first identified in the 1980s, and eventually linked to warming events, the scientific community was sure that such a dramatic and unambiguous signal would serve as a warning sign about the devastating effects of global warming. Instead, most people ignored that warning. Subsequent decades have witnessed yet more degradation. Reefs around the world have lost more than 50 percent of their living coral since the 1970s. In this book, distinguished marine ecologist Peter F. Sale imparts his passion for the unexpected beauty, complexity, and necessity of coral reefs. By placing reefs in the wider context of global climate change, Sale demonstrates how their decline is more than simply a one-off environmental tragedy, but rather an existential warning to humanity. He offers a reframing of the enormous challenge humanity faces as a noble venture to steer the planet into safe waters that might even retain some coral reefs.

How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness.

The coelacanth (see-lo-canth) is no ordinary fish. Five feet long, with luminescent eyes and limb like fins, this bizarre creature, presumed to be extinct, was discovered in 1938 by an amateur icthyologist who recognized it from fossils dating back 400 million years. The discovery was immediately dubbed the "greatest scientific find of the century," but the excitement that ensued was even more incredible. This is the entrancing story of that most rare and precious fish -- our own great-uncle forty million times removed.

This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.
