Salmon are one of the most popular and commonly eaten fish and are
among the most important fishery resources in the world. They are
born and die in fresh water but can live in both fresh water and
seawater where they migrate between rivers and oceans, showing
amazing abilities to home to their natal stream precisely. However,
their dynamic life cycles and mysterious abilities of natal stream
imprinting and homing migration are not well understood.
Physiological Aspects of Imprinting and Homing Migration in Salmon:
Emerging Researches and Opportunities is a pivotal reference source
that introduces the dynamic and complicated life cycle of salmon
connected with fish migration and climate changes and presents
physiological mechanisms of natal stream imprinting and homing in
salmon with special references to hormone, olfaction, memory, and
behavior. Additionally, salmon resources concerning salmon
commercial fisheries, aquaculture, and global propagation systems
are discussed. This book is ideally designed for ichthyologists,
environmentalists, pisciculture professionals, fisheries, marine
biologists, scientists, researchers, academicians, and students
seeking coverage on one of the most integral species of fish in the
world.
An informative series that provides, in a concise format, better
understanding of animals and their habitats. Fascinating in its
diversity, the natural world comes to life on the pages of these
spec tacularly illustrated volumes.
This book (hardcover) is part of the TREDITION CLASSICS. It
contains classical literature works from over two thousand years.
Most of these titles have been out of print and off the bookstore
shelves for decades. The book series is intended to preserve the
cultural legacy and to promote the timeless works of classical
literature. Readers of a TREDITION CLASSICS book support the
mission to save many of the amazing works of world literature from
oblivion. With this series, tredition intends to make thousands of

Dive deep into the world of sharks, the most fascinating and
misunderstood marine animals on the planet, in this stunning new
edition of The Shark Handbook, written by Shark Week expert, Dr.
Greg Skomal. Did you know that a whale shark's spots are as unique
as a fingerprint? Or that sharks can go into a trance when flipped
upside down? Or that the Megallodon's mouth was 6 feet across? With
The Shark Handbook, jump into brand new facts about these fierce
sea creatures! Explore all of the orders of sharks, such as: -
Ground sharks - Great white sharks - Mackerel sharks - Carpet
sharks - and more! Learn about over 400 profiles of every shark in
existence, from the first sharks living about 445 million years ago
to the ones lurking in the ocean deep today. Starring spectacular,
full-color photography that makes these jaw-dropping sharks come to
life, this is the perfect gift for the shark enthusiast in your
life. Dr. Greg Skomal, PhD is an experienced aquarist and Marine
Fisheries Biologist at Martha's Vineyard Fisheries, Division of
Marine Fisheries, Massachusetts. He's been keeping saltwater
aquariums since childhood and has shared his extensive knowledge
with viewers of National Geographic, the Discovery Channel, NBC's
Today, and other media.
One of the planet's oldest and most misunderstood animals, this
guide helps to de-mystify sharks and inform about their value in
the ocean eco-system. The World of Sharks -- edited by world-famous
naturalist Jeff Corwin -- teaches about the way sharks evolved, how
they are built and how they behave, reproduce and survive in
different habitats around the world. It also highlights some of the
most familiar and unique species found worldwide, their current
status, what to do if you encounter a shark in the wild and what
you can do to help to conserve and protect these spectacular
creatures. This folding pocket guide is the ideal reference for
shark-lovers and teachers alike. Made in the USA.
The definitive field guide to all the sharks, rays and chimaeras of

identification features, habitat, biology and status. Every species
account comes with a colour distribution map, a depth guide,
at-a-glance icons and colour illustrations. This must-have field
guide also features illustrated key guides that enable you to
accurately identify down to species, comparison plates of similar
species, illustrations of eggcases where known and plates of teeth.

A transporting exploration of the deep sea, and how our planet’s strangest, most ancient and astonishing creatures have urgent relevance to cutting-edge science today.
Hundred-year-old giant clams, coral kingdoms the size and shape of cities, and jellyfish that glow in the dark: ocean invertebrates are among the oldest and most diverse organisms on Earth, seeming to bend the rules of land-based biology. Although sometimes unseen in the deep, these incredible spineless creatures contain 600 million years of adaptation to problems of disease, energy consumption, nutrition, and defence.
Marine ecologist Dr Drew Harvell takes us diving from Hawaii to the Salish Sea, from the Caribbean to Indonesia, to uncover the incredible underwater ‘superpowers’ of spineless creatures: we meet corals many times stronger than steel or concrete, sponges who create potent chemical compounds to fight off disease, and sea stars who garden the coastlines, keeping all the other nearby species in perfect balance. As our planet changes fast, the biomedical, engineering and energy innovations of these wondrous creatures hold ever more important secrets to our own survival.
The Ocean’s Menagerie is a tale of biological marvels, a story of a woman’s passionate connection to an adventurous career in science and a call to arms to protect the world’s most ancient ecosystems.
The book is a combination of all the things pertaining to my
fishing for so many years. It is how I got started, what I learned,
who I met, what I caught, what interesting things happened. I am
not through learning or enjoying my life doing this. There is
always something new tomorrow.
The pictures are of the people that I knew, myself, odd things
we caught, or odd things that happened.
Fishermen of Taupo is a book about the fly fishermen of New
Zealand's Lake Taupo. It tells the individual stories of twenty
Taupo fishermen that I have been fortunate enough to fish with over
the years. Taupo is, and still remains, a gem, but with the world
getting ever smaller due to air travel, this fishery is fragile.
Still it remains, like its trout, wild. It needs protecting before
it's lost.
A revealing and authoritative history that shows how Soviet whalers
secretly helped nearly destroy endangered whale populations, while
also contributing to the scientific understanding necessary for
these creatures' salvation. The Soviet Union killed over 600,000
whales in the twentieth century, many of them illegally and
secretly. That catch helped bring many whale species to near
extinction by the 1970s, and the impacts of this loss of life still
ripple through today's oceans. In this new account, based on
formerly secret Soviet archives and interviews with ex-whalers,
environmental historian Ryan Tucker Jones offers a complete history
of the role the Soviet Union played in the whales' destruction. As
other countries-especially the United States, Great Britain, Japan,
and Norway-expanded their pursuit of whales to all corners of the
globe, Stalin determined that the Soviet Union needed to join the
hunt. What followed was a spectacularly prodigious, and often
wasteful, destruction of humpback, fin, sei, right, and sperm
whales in the Antarctic and the North Pacific, done in knowing
violation of the International Whaling Commission's rules. Cold War
intrigue encouraged this destruction, but, as Jones shows, there is
a more complex history behind this tragic Soviet experiment. Jones
compellingly describes the ultimate scientific irony: today's
cetacean studies benefitted from Soviet whaling, as Russian
scientists on whaling vessels made key breakthroughs in
understanding whale natural history and behavior. And in a final
twist, Red Leviathan reveals how the Soviet public began turning
against their own country's whaling industry, working in parallel
with Western environmental organizations like Greenpeace to help
end industrial whaling-not long before the world's whales might
have disappeared altogether.
