Critically endangered porpoise is focus of new research report
January 15, 2008An international research team, including biologists from NOAA's Fisheries Service, reported in the scientific journal Conservation Biology, that the estimated population of vaquita, a porpoise found in the Gulf of California, is likely two years away from reaching such low levels that their rate to extinction will increase and possibly be irreversible. Scientists believe only about 150 vaquita remain.
The research team, led by Armando Jaramillo, Instituto Nacional de Ecología, Mexico, included researchers Barbara Taylor, NOAA's Fisheries Service, and Randy Reeves Reeves, Chair of the Cestacean Specialist Group, IUCN - the World Conservation Union. The group assessed the number of vaquita based on past estimates of abundance and deaths in fishing nets together with current fishing effort. Approximately 30 vaquita drown each year in the Gulf of California when they become entangled in nets set for fish and shrimp.
Vaquita are found only in a small area of productive, shallow water in the northernmost Gulf of California. They are listed as endangered species by the United States and Mexico and critically endangered by the World Conservation Union.
Researchers cite worrisome parallels between vaquita and the baiji, a freshwater dolphin in the Yangtze River, which was recently declared likely to be extinct; primarily from entanglement in fishing gear.

With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life.
TEEB report released on the economics of ecosystems and biodiversity for policy makers

Studies show marine reserves can be an effective tool for managing fisheries
Studies conducted in California and elsewhere provide support for the use of marine reserves as a tool for managing fisheries and protecting marine habitats, according to biologists at the University of California, Santa Cruz.
Coral reefs inspire rare consensus -- just save them
One of the first set of studies to examine what tourists and recreation enthusiasts actually think about coral reef ecosystems suggests they are a rare exception to controversies over human use versus environmental conservation - their stunning beauty is so extraordinary that almost everyone wants them protected in perpetuity.
North Atlantic Fish Populations Shifting as Ocean Temperatures Warm
About half of 36 fish stocks in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the last four decades, with some stocks nearly disappearing from U.S. waters as they move farther offshore, according to a new study by NOAA researchers.
Remotely Operated Vehicles and Satellite Tags Aid Turtle Studies
Researchers are using a remotely operated vehicle (ROV) and satellite-linked data loggers to learn more about turtle behavior in commercial fishing areas and to develop new ways to avoid catching turtles in fishing gear.

Fisheries Biology, Assessment and Management by Michael King (Author) This excellent second edition of Fisheries Biology, Assessment and Management, has been fully updated and expanded, providing a book which is an essential purchase for students and scientists studying, working or researching in fisheries and aquatic sciences. In the same way that excessive hunting on land has threatened terrestrial species, excessive fishing in the sea has reduced stocks of marine species to dangerously low levels. In addition, the ecosystems that support coastal marine species are threatened by habitat destruction, development and pollution. Open access policies and subsidised fishing are placing seafood in danger of becoming a scarce and very expensive commodity for which there is an insatiable demand. Positive trends include actions being... |

Fisheries Ecology and Management by Carl J. Walters (Author), Steven J. D. Martell (Author) Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement... |

Marine Fisheries Ecology by Simon Jennings (Author), Michel Kaiser (Author), John D. Reynolds (Author) CLICK HERE TO DOWNLOAD ARTWORK This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing,... |
