Book Description
Honor Frost has written a travel book with this difference: her journeys have extended below the surface of the sea. Her accounts of these regions can be compared with the writings of early travellers who, unhampered by overspecialization, recorded a variety of observations on completely unknown places. In setting down her direct experience she has thrown new light on the much discussed submect of underwater archaeology. This book contains 22 colour and 28 monochrome photographs by well known divers, also 52 plans and drawings by the author illustrating her arguments. It is addressed to travell.

Book Description
Humanity can make short work of the oceans’ creatures. In 1741, hungry explorers discovered herds of Steller’s sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It’s a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail. As Callum M. Roberts reveals in The Unnatural History of the Sea, the oceans’ bounty didn’t disappear overnight. While today’s fishing industry is ruthlessly efficient, intense exploitation began not in the modern era, or even with the dawn of industrialization, but in the eleventh century in medieval Europe. Roberts explores this long and colorful history of commercial fishing, taking readers around the world and through the centuries to witness the transformation of the seas. Drawing on firsthand accounts of early explorers, pirates, merchants, fishers, and travelers, the book recreates the oceans of the past: waters teeming with whales, sea lions, sea otters, turtles, and giant fish. The abundance of marine life described by fifteenth century seafarers is almost unimaginable today, but Roberts both brings it alive and artfully traces its depletion. Collapsing fisheries, he shows, are simply the latest chapter in a long history of unfettered commercialization of the seas. The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendor and prosperity of the seas through smarter management of our resources and some simple restraint. From the coasts of Florida to New Zealand, marine reserves have fostered spectacular recovery of plants and animals to levels not seen in a century. They prove that history need not repeat itself: we can leave the oceans richer than we found them.

Book Description
Most of the major impacts of fishing on the ecosystems recorded around the world occur in the Mediterranean. This variety of interactions is due to four main interrelated factors: the wide range of fishing gear and practices; very intensive fishing; a high diversity of exploited habitats, ranging from shallow water to the deep-sea and oceanic domain; and high biological diversity.

Book Description
Drawing on a number of case studies from around the world, this publication considers how the local knowledge and practices of indigenous fishing communities are being used in collaboration with scientists, government managers and non-governmental organisations to establish effective frameworks for sustainable fisheries science and management. It seeks to contribute towards achieving the goal of establishing international responsibility for the ethical collection, preservation, dissemination and application of fishers' knowledge.
