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.

Modifications of lures and development of new baits and techniques continue to keep the fare fish, and that's important. Bass seem to become "accustomed" to the same artificials and presentations seen over and over again. As a result, they become harder to catch. It's the new approach that again sparks the interest on the largemouth. To that end, this book explores some of the latest ideas for modifying; rigging and using bass lures. All are highly effective when utilized in the correct environment and conditions. The book details productive trick modifications and tactics that any novice or professional angler can apply to catch more bass with artificial lures.
The conservation of marine benthic biodiversity is a recognised goal of a number of national and international programs such as the United Nations Convention on Biodiversity (CBD). In order to attain this goal, information is needed about the distribution of life in the ocean so that spatial conservation measures such as marine protected areas (MPAs) can be designed to maximise protection within boundaries of acceptable dimensions. Ideally, a map would be produced that showed the distribution of benthic biodiversity to enable the efficient design of MPAs. The dilemma is that such maps do not exist for most areas and it is not possible at present to predict the spatial distribution of all marine life using the sparse biological information currently available.
Knowledge of the geomorphology and biogeography of the seafloor has improved markedly over the past 10 years. Using multibeam sonar, the benthic ecology of submarine features such as fjords, sand banks, coral reefs, seamounts, canyons, mud volcanoes and spreading ridges has been revealed in unprecedented detail.
This book provides a synthesis of seabed geomorphology and benthic habitats based on the most recent, up-to-date information. Introductory chapters explain the drivers that underpin the need for benthic habitat maps, including threats to ocean health, the habitat mapping approach based on principles of biogeography and benthic ecology and seabed (geomorphic) classification schemes. Case studies from around the world are then presented. They represent a range of seabed features where detailed bathymetric maps have been combined with seabed video and sampling to yield an integrated picture of the benthic communities that are associated with different types of benthic habitat. The final chapter examines critical knowledge gaps and future directions for benthic habitat mapping research.
Reviews and compares the different methodologies currently being used Includes global case studiesProvides geological expertise into what has traditionally been a biological discipline
First published in 1990, The Economics of Salmon Aquaculturewas the first book to systematically analyse the salmon aquacultureindustry, from both a market and production perspective.

Sport climbers often project a route that tests their physical limits in hopes of an eventual completion. Succeeding requires a solid understanding of great belaying and other lead-climbing techniques that aren't found in other climbing disciplines–but are detailed here in this accessible new guide.
Targeting all abilities, Sport Climbing teaches climbers how to rehearse moves and train for specific routes, how to get through the pump, how to fight until the end of a pitch, how to stay composed when tired, and how to best use their bodies to climb efficiently and expertly. Whether inspiring new climbers to learn the nuances of scaling vertical terrain, or delving into a deeper, more conceptual understanding of how to go about projecting a route, Andrew Bisharat brings confidence and a level of practicality to the sport. He reveals how the skills specific to redpointing transfer over to all climbing disciplines, making this a must-have book for any climber. Featuring anecdotes from famous climbers such as Tommy Caldwell, Katie Brown, Boone Speed, Josh Wharton, and Alex Honnold, the author brings a modern voice to a complex sport.
