From the fifty-one-foot whale shark Rhincodon typus to a less-than-one-half-inch fish in the minnow family--the tiny Paedocypris progenetica--fish certainly carry a lot of weight . . . or do they?

A fish's heft in water may vary, but these diverse aquatic animals certainly carry a lot of weight in our ecosystems and environment. From freshwater to ocean habitats, Judith S. Weis offers a fascinating look at these deceptively simple creatures. Fishes may appear to live a dull existence, but appearances change once we understand more about how they survive. These wonders actually possess attributes that would make us superpowers--they can change color, sex, produce light and electricity, regenerate injured fins, prevent themselves from sinking, and some can even walk on land.

A captivating read for fish enthusiasts of all ages--naturalists, environmentalists, aquarists, scuba divers, and students--this is also the perfect primer for those just about to get their feet wet. Dive in!

The history of biology is populated by numerous model species or organisms. But few vertebrate groups have aided evolutionary and ecological research more than the live-bearing fishes of the family Poeciliidae. Found throughout tropical and subtropical waters, poeciliids exhibit a fascinating variety of reproductive specializations, including viviparity, matrotrophy, unisexual reproduction, and alternative mating strategies, making them ideal models for research on patterns and processes in ecology, behavior, and evolution.

Ecology and Evolution of Poeciliid Fishes is a much-needed overview of the scientific potential and understanding of these live-bearing fishes. Chapters by leading researchers take up a wide range of topics, including the evolution of unisexual reproduction, life in extreme environments, life-history evolution, and genetics. Designed to provide a single and highly approachable reference, Ecology and Evolution of Poeciliid Fishes will appeal to students and specialists interested in all aspects of evolutionary ecology.

When pulled from the mud of creeks, ponds, rivers, or the sea, the eel, with its slick, snake-like body, emerges as an extremely mundane and even unappealing fish. But don’t let the appearance fool you—the eel has been one of the world’s favorite foods since ancient Greece, and the eel’s life cycle is one of the most remarkable on the planet—during the middle ages, impoverished Londoners survived on eel and the eel later saved the Mayflower pilgrims from starvation on American shores.

            In Eel, RichardSchweid chronicles the many facets of these slippery creatures from their natural history to their market value and contemporary consumption to their appearance in art and literature and finally to their present threatened status. So far, eels have steadfastly refused to reproduce in captivity, apparently requiring the vastness of the open ocean to successfully mature—which has imperiled the species’ long-term survival. Schweid explains that freshwater eels are born in remote ocean depths and make a journey of thousands of miles to fresh water where they spend most of their lives before making a return journey to the ocean to mate and die.

            Well-illustrated and containing many little-known facts about this surprising fish, Eel will appeal to general readers of natural history and others wishing to discover something more about the common unagi on the sushi menu.

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.

Fishes of the Minnesota Region was first published in 1982. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.

From Northern Pike to the Walleye, this is the definitive guide to all of Minnesota's 149 kinds of fishes. Illustrated with over 80 color photographs, this book will appeal to enthusiastic anglers as well as curious naturalists.

Along with a guide to identification, the authors cover habitat, distribution, conservation, and even some recipes. If you catch a fish from one of Minnesota's 10,000 lakes you'll find a description of it in this book.

Fisheries management today is highly contentious. The interests of fishers and fish processors, coastal communities, the government, and environmental organizations are often different and can even be mutually incompatible.

Fishing Grounds offers a comprehensive assessment of the legal, social, economic and biological context of marine fisheries management in the United States. Drawing on interviews with stakeholders from all sides of the issue, the authors seek common ground -- and points of unresolved controversy -- among the diversity of interests and viewpoints involved. Chapters examine:

• history and background
• status of marine fisheries
• fishery productivity from biological, social, and economic perspectives
• ownership of fishery resources
• management structures and incentives
• the roles of science and evaluation

Fishing Grounds presents a useful overview of fisheries management options and positions regarding those options, providing valuable insight into the opinions and concerns of stakeholders and the sets of incentives to which those stakeholders respond. It is an important work for fisheries management professionals in industry, government agencies, and nongovernmental organizations, as well as for students and researchers involved with fisheries and fisheries management.

Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems.

In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book:

• provides a snapshot of the past health of the North Atlantic and compares it to its present status
• presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level
• considers the factors that have led to the current situation
• describes the policy options available for halting the decline
• offers recommendations for restoring the North Atlantic

This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.

Northern Fishes was first published in 1974. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.

With the greatly increased interest in fishes and fishing since the earlier editions of this work were published, there has been need for a revised version of this indispensable book on the fishes of the Upper Mississippi Valley. This, the third edition, revised, of Northern Fishes by Samuel Eddy and Thaddeus Surber, contains much new material and up-to-date information based on current knowledge about fishes, their environment, and fishing techniques.

The book covers more than 160 species with descriptions and line drawings to illustrate almost all of them. The authors discuss recently introduced species and their importance to sportsmen and provide current data on the distribution of northern fishes. There are keys for the identification of the species and information about where they are found and their habits. This edition also contains a number of additions to the species list which result from rather extensive collecting of specimens since the earlier editions were compiled.

Before presenting the data on individual species, the authors provide basic information about fishes in general—their structure, classification and origin, their food, and their parasites. The revised, updated section on fishing techniques includes information about spin casting. There are important chapters on lake dynamics, fish population dynamics, management of Minnesota and northern waters for fish production, and improvement of lakes and streams. The detailed information about species is arranged according to families. For further reading or reference there is a bibliography.

America’s western rivers are under assault from development, pollution, invasive species, and climate change. Returning these eco- systems to the time of European contact is often the stated goal for restoration efforts, yet neither the influence of indigenous societ- ies on rivers at the time of contact nor the deeper evolutionary relationships are yet understood by the scientific world. This volume presents a unique synthesis of scientific discoveries and traditional knowledge about the ecology of iconic river species in the American West.

Building from a foundation in fisheries biology and life history data about key species, the book reveals ancient human relationships with those species and describes time-tested Native resource management techniques, drawing from the archaeological record and original ethnographic sources. It evaluates current research trends, summarizes the conceptual foundations for the cultural and evolutionary significance of sustainable use of fish, and seeks pathways for future research. Geographic areas described include the Columbia Plateau, Idaho’s Snake River Plain, the Sacramento River Delta, and the mid-Fraser River of British Columbia. Previously unpublished information is included with the express permission and approval of tribal communities. This approach broadens and deepens the available body of data and establishes a basis for future collaboration between scientists and Native stakeholders toward mutual goals of river ecosystem health. 

"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.

When populations of striped bass began plummeting in the early 1980s, author and fisherman Dick Russell was there to lead an Atlantic coast conservation campaign that resulted in one of the most remarkable wildlife comebacks in the history of fisheries. As any avid fisherman will tell you, the striped bass has long been a favorite at the American dinner table; in fact, we've been feasting on the fish from the time of the Pilgrims. By 1980 that feasting had turned to overfishing by commercial fishing interests. Striper Wars is Dick Russell's inspiring account of the people and events responsible for the successful preservation of one of America's favorite fish and of what has happened since.

Striper Wars is a tale replete with heroes--and some villains--as the struggle to save the striper migrated down the coast from Massachusetts to Maryland. Russell introduces us to a postman at arms against a burly trap-net fisherman, a renowned state governor caving to special interests, and a fishing-tackle maker fighting alongside marine biologists. And he describes how champions of this singular fish blocked power plants and New York's Westway Project that would otherwise compromise its habitat. Unfortunately, those who cheered the triumphant ending to the campaign, as the coastal states enacted measures that enabled the striped bass to make its comeback, have found the peace transitory--there is now a new enemy emerging on the front.

In recent years a chronic bacterial disease has struck more than seventy percent of the striped bass population in the primary spawning waters of the Chesapeake Bay. Malnutrition seems to be a significant factor, brought on by the same overfishing that plagued the bass in the first battle--only this time, the overfishing is devastating menhaden, the silvery little fish upon which the bass feed. Lessons learned during the first conservation battle are being applied here, highlighting a need for a whole new ecosystem-based approach to conserving species.

Only with constant vigilance by concerned citizens, Dick Russell reminds us, can environmental victories be sustained. This particular fish story is a personal one for him, and he follows the striper's saga today all the way to California, where the fish was introduced in 1879 and where agribusiness now threatens its future. For his conservation work during the 1980s Russell received a citizen's Chevron Conservation Award.
