A New York Times Bestseller Do fishes think? Do they really have three-second memories? And can they recognize the humans who peer back at them from above the surface of the water? In What a Fish Knows, the myth-busting ethologist Jonathan Balcombe addresses these questions and more, taking us under the sea, through streams and estuaries, and to the other side of the aquarium glass to reveal the surprising capabilities of fishes. Although there are more than thirty thousand species of fish—more than all mammals, birds, reptiles, and amphibians combined—we rarely consider how individual fishes think, feel, and behave. Balcombe upends our assumptions about fishes, portraying them not as unfeeling, dead-eyed feeding machines but as sentient, aware, social, and even Machiavellian—in other words, much like us. What a Fish Knows draws on the latest science to present a fresh look at these remarkable creatures in all their breathtaking diversity and beauty. Fishes conduct elaborate courtship rituals and develop lifelong bonds with shoalmates. They also plan, hunt cooperatively, use tools, curry favor, deceive one another, and punish wrongdoers. We may imagine that fishes lead simple, fleeting lives—a mode of existence that boils down to a place on the food chain, rote spawning, and lots of aimless swimming. But, as Balcombe demonstrates, the truth is far richer and more complex, worthy of the grandest social novel. Highlighting breakthrough discoveries from fish enthusiasts and scientists around the world and pondering his own encounters with fishes, Balcombe examines the fascinating means by which fishes gain knowledge of the places they inhabit, from shallow tide pools to the deepest reaches of the ocean. Teeming with insights and exciting discoveries, What a Fish Knows offers a thoughtful appraisal of our relationships with fishes and inspires us to take a more enlightened view of the planet’s increasingly imperiled marine life. What a Fish Knows will forever change how we see our aquatic cousins—the pet goldfish included.

Fishing has played a vital role in human history and culture. But today this key resource faces a serious crisis as most species are being overfished or fished to their very limit. Governments have tried to tackle the problem with limited success. Many of their actions have been counterproductive or ineffective. What will happen to global fisheries, and the populations that depend on them, as we continue to catch more fish than the oceans can reproduce? This book explores the causes of the current crisis in the world's fisheries, and what needs to be done to address the situation. It explains the structure of the fishing industry, the incentives that persuade individuals or companies to catch fish at unsustainable levels, and illuminates the problems created by governmental efforts to use fishing policy as a tool for economic development or to win votes in domestic elections. It also looks at the role of aquaculture in either decreasing or increasing the pressure on wild fish stocks. The dire condition of fish stocks has led governments and consumer organizations to consider new approaches to protect the global supply of fish. DeSombre and Barkin conclude by showing how such methods, along with new forms of international regulation and informed decision-making by consumers, all have an important part to play in rewarding and thus encouraging sustainable fishing behaviour in the future.

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. Do Fish Sleep? is organized in an easy-to-read and accessible question-and-answer format, filled with more than 55 photographs and over 100 interesting facts from fish biology basics to the importance of preserving and restoring fish diversity and healthy populations. 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.

Do Fish Feel Pain

While there has been increasing interest in recent years in the welfare of farm animals, fish are frequently thought to be different. In many people's perception, fish, with their lack of facial expressions or recognisable communication, are not seen to count when it comes to welfare. Angling is a major sport, and fishing a big industry. Millions of fish are caught on barbed hooks, or left to die by suffocation on the decks of fishing boats. Here, biologist Victoria Braithwaite explores the question of fish pain and fish suffering, explaining what we now understand about fish behaviour, and examining the related ethical questions about how we should treat these animals. She asks why the question of pain in fish has not been raised earlier, indicating our prejudices and assumptions; and argues that the latest and growing scientific evidence would suggest that we should widen to fish the protection currently given to birds and mammals.
