This book sets out to bridge the order scales among pike researchers, populations, communities, management, and fisheries. It emphasizes the progress of pike research during the last two decades, during which the order-bridging approach emerged. This framework underpins the text and the message, to convey its importance to pike research and to fish research in general. In addition, a considerable part of the book is devoted to management implications and highlights aspects of human dimensions in recreational fisheries.

This comprehensive book on the venomous stingrays of the world seas and freshwater systems provides first-hand information on the diversity, biology, and ecology of venomous stingrays of freshwater, brackish, and marine ecosystems.

Each year thousands of injuries to swimmers and surfers are reported, with 750 to 1,500 stingray injuries reported each year in the US alone. As more vacationers spend their leisure time exploring coasts and tropical reefs, often in isolated areas without immediate access to advanced health care, there will be greater potential for stingray...

As featured in the documentary, DamNation (Patagonia, 2014). During his first summer, Spencer built a sheltered viewing platform, a place to sit with Sis and his notebook, and observe the denizens of the pool for months, and, finally, years on end. Shortly before setting up camp during his first season, Spencer cut the points off the hooks of all his steelhead flies, freeing himself to see more deeply the beauty of his surroundings. As the predatory urge faded, a kind of blindness went with it, and Spencer's eyes and mind became figurative hooks, enabling him to capture the...

Ecologists have long struggled to understand community dynamics. In this groundbreaking book, leading fish ecologists William Matthews and Edie Marsh-Matthews apply long-term studies of stream fish communities to several enduring questions. This critical synthesis reaches to the heart of ecological theory, testing concepts against the four decades of data the authors have collected from numerous warm-water stream fish communities in the central and eastern United States.

Stream Fish Community Dynamics draws together the work of a single research team to provide fresh analyses...

The Driftless Area in rural southwestern Wisconsin has some of the most productive spring creeks in the world. Brown trout numbers can reach 5000 catchable fish per mile in creeks only 10 meters wide. The author goes fishing with a local self-described "trout regs protester," to look at the social and biological impacts of special regulations designed to promote and protect this fishery as a destination for out of state traveling fly fishers and local anglers alike. The former have flocked to this region over the years, the later have dropped out in high numbers. The author investigates...

"It's fascinating ... Tells] how fishing is an integral part of America." -- BILL O'REILLY, The O'Reilly Factor

"The perfect Christmas gift for the fishing enthusiast in your family" (Daily Caller), The American Fisherman, by outdoorsman Willie Robertson (CEO of Duck Commander and star of A&E's Duck Dynasty) and bestselling historian William Doyle, reveals that in the U.S.A., fishing is far more than a pastime--it has shaped our past and defined our character in remarkable ways.
