The incredible adventure of Annie Ricketson's years at sea, as told so simply in her journal, is impressive even by today's standards. Very few women in the 1870s would have chosen to do what Annie did. The idea of leaving family and friends for nearly three and one half years to sail to areas of the world which were not even listed on a map must have been daunting, but to do this as the only woman on a ship where some of the crew may have resented a woman onboard, and others may not have had the highest character references, was absolutely courageous. Annie sailed on the A. R. Tucker with her husband, Captain Daniel Ricketson, to many of the world's whaling grounds. Her journey took her from her home port of New Bedford, Massachusetts, down the Atlantic around the Cape of Good Hope in South Africa, and across the Indian Ocean to the Pacific off the coast of Australia. Her journal entries not only tell of tragedy and death, of dangers and bad weather but also of friendly natives and sightseeing, shopping and fashion concerns. They are an invaluable record of life onboard a whaling ship-the excitement of the hunt, a powerful storm, even an earthquake-and the boredom of day after day when nothing happened. Annie's love for her husband and adventure, her sense of humor and her amazing ability to adapt is obvious from the very beginning of her fantastic story.

Oysters - Biology, Consumption & Ecological Importance (Paperback): Judith P Turner Oysters - Biology, Consumption & Ecological Importance (Paperback)
Judith P Turner
R1,989 Discovery Miles 19 890 Ships in 12 - 19 working days

Oyster reefs provide valuable habitat for many ecologically and economically important species, as well as stabilizing benthic and intertidal habitats. Their bioactivity and structure creation leads to a greater abundance and diversity of other aquatic species. This book focuses on the eastern oyster's aquaculture and diversity of associated species; the cadmium conundrum in British Columbian oysters; the problems and risks related to an exotic oyster introduction case; and the expansion of distribution among spionid polychaetes by accompanying oyster shells during transportation.

Jorn Gessner, Martin Hochleithner
R1,171 Discovery Miles 11 710 Ships in 10 - 15 working days

The breeding and culture of sturgeons and paddlefishes (Acipenseriformes) in captivity has advanced rapidly over the past several years. With recent developments, the requirements of the industry have changed, and the techniques used have also evolved and been adapted to meet these changing needs. Based on experience gained in the the former USSR, new technologies have been developed, and the background of sturgeon biology has been enlightened in many respects. This book is designed to close the information gap between scientists and practitioners. Its appeal will be far reaching since biologists, field technicians, hatchery operators and fish farmers, fisherman and fish enthusiasts, will all find a wealth of practical information relevant to their field of interest. The book has the style of a species synopsis coupled with everything anyone needs to know about the reproduction and culture of acipenserid fishes. It summarizes current knowledge on all sturgeon and paddlefish species worldwide and presents it as a practitioner-oriented working guide. It draws on the experience and research findings of the authors gained over more than two decades. This new, third edition has been updated, extended, and reviewed, and includes many new colour illustrations. It value will be timeless.

Silent Seas - The Fish Race to the Bottom (Paperback): Isabella Lovin Silent Seas - The Fish Race to the Bottom (Paperback)
Isabella Lovin
R586 Discovery Miles 5 860 Ships in 10 - 15 working days

"Isabella L vin writes with great passion and clarity about the crisis facing global fish stocks. Exposing the weak short termism of governments, and the persistent failure of the EU fisheries policy to act on the clear science, her warning is unequivocal: act soon or lose vast sections of this vital source of food forever. But it's not all gloom and doom. She is clear that this is a solvable problem - and that until governments legislate more responsibly, consumer action is the best means for bringing about change. A compelling book, that all those who care about the future of our oceans will want to read." HUGH FERNLEY-WHITTINGSTALL, HUGH'S FISH FIGHT "Who would have thought that Sweden, of all places, would have allowed its fisheries to reach the sorry state documented in Isabella L vin's essential book? We are surprised and dismayed, but should we be? What Ms. L vin demonstrates is that the public's notion about fisheries being benign stakeholders of the sea is deeply flawed. Rather, fisheries, as presently 'managed', are actively destroying marine ecosystems and public resources with the financial and administrative support of governments. Ms. L vin uses the Baltic, and the eel and cod as her main examples, yet this bok is not about Sweden and the Baltic - it is about a mindset prevailing throughout Europe and in much of the world, and which we desperately need to change. This book will make you want to join the battle." DR. DANIEL PAULY, FISHERIES CENTRE, UNIVERSITY OF BRITISH COLOMBIA "Silent Seas is the Da Vinci Code of fisheries policy. A page turner where the same question keeps turning over and over inside your head: Who is the killer? Who killed our seas? " STEFAN NYSTR M, SWEDISH FISHERIES MAGAZINE "Read Silent Seas. Then contact your MP " GUNVOR HILLDEN, UPSALA NYA NEWSPAPER Silent seas was first published in Swedish in 2007, and was soon awarded no less than 14 prizes, among which the prestigious Great Journalism Award, the Investigative Journalism Award, the Environmental Journalism of the Year Award and the Baltic Sea Award. Isabella L vin became a candidate for the Swedish Greens in the elections for the European parliament in 2009, and is now actively working to reform the EU common fisheries policy. The present English edition has been updated, and a new foreword has been added in 2012.

Common carp are hugely popular in aquaculture, course angling, commercial fisheries and as an ornamental fish. While their native range extends from the lakes and rivers of Japan to the Danube Basin in Eastern Europe, their usefulness has led to them being introduced to many waterways outside their native range. In this book, the authors present topical research in the study of the habitat, management and diseases of carp. Included in this compilation are the strategic management of the photoperiodic schedule and melatonin profile in the regulation of carp reproduction; invasive parasites of common carp in Europe; impacts of the common carp on freshwater ecosystems and the utilisation of carbon, nitrogen and phosphorus in carp culture ponds..

Craig Welch
R368 Discovery Miles 3 680 Ships in 10 - 15 working days

In "Shell Games," journalist Craig Welch delves into our nation's waters and wildlands in search of America's most unusual criminals. The resulting detective story is filled with butterfly thieves, bear poachers, shark-trafficking pastors--and a rogues' gallery of double-crossing crooks who get rich smuggling bizarre marine creatures.

Puget Sound is home to the geoduck (pronounced "gooey duck"), the world's largest burrowing clam--a seafood delicacy worth millions on the international black market. Outlaw scuba divers pursue this prize while dodging cops, committing arson, and hiring hit men to eliminate their rivals. Detective Ed Volz has spent decades chasing fish and wildlife smugglers. Now, he and a team of federal agents are desperate to take down the most remarkable thief they've ever hunted: a darkly charming con man who works both sides of the law and calls himself the "Geoduck Gotti."

Flatheads and Spooneys - Fishing for a Living in the Ohio River Valley (Paperback): Jens Lund Flatheads and Spooneys - Fishing for a Living in the Ohio River Valley (Paperback)
Jens Lund
R795 Discovery Miles 7 950 Ships in 10 - 15 working days

Since the early 1800s, people have made a living fishing and harvesting mussels in the lower Ohio Valley. These river folk are conscious of an occupational and social identity separate from those who earn their living from the land. Sustained by a shared love of the river, deriving joy from the beauty of their chosen environment, and feeling great pride in their ability to subsist on its wild resources and to master the skills required to make a living from it, many still identify with the nomadic houseboat-dwelling subculture that flourished on the river from the early nineteenth century to the 1950s.

Today's community of fisherfolk is small and economically marginal, but their activities sustain a complex set of traditional skills and a body of verbal folklore associated with river life. In Flatheads and Spoonies, Jens Lund describes the activities, boats, gear, verbal lore, and sense of identity of the fisher folk of the lower Ohio River Valley and provides historical and ethnobiological background for their way of life. Lund connects the importance of river fish in the diet of inhabitants of the valley to local fishing activities and explores the relationship between river people and those whose culture is primarily land-based, painting a colorful portrait of river fishing and river life.

This book offers a look -- historical and ethnographic -- at a little-known aspect of traditional life in the American Midwest, still surviving today despite immense changes in environment, resources, and economic base.

Terranova - The Spanish Cod Fishery on the Grand Banks of Newfoundland in the Twentieth Century (Paperback): Rosa Garcia-Orellan Terranova - The Spanish Cod Fishery on the Grand Banks of Newfoundland in the Twentieth Century (Paperback)
Rosa Garcia-Orellan
R926 Discovery Miles 9 260 Ships in 10 - 15 working days

Terranova is the story of Spain's twentieth-century industrial cod fishery on the Grand Banks of Newfoundland. It combines oral history (including interviews with over 300 participants in the fishery) with socio-political-economic history to describe how the industry and Spain itself evolved over seven decades. Terranova pays special attention to how work and life onboard trawlers changed in 1926, when Spain's industrial fishery began, and how they have evolved through the turn of the twenty-first century. It concludes by describing how technological advances and increased competition among fishers brought the collapse of the Newfoundland cod fishery in 1992.
