Alternative To Sustainable Fisheries

Biologists from Kiel and Vancouver present a simple way to estimate Maximum Sustainable Yield Up to now, methods to estimate the maximum sustainable yield (MSY) of fish stocks are very complex and, as a consequence, expensive. However, Dr Rainer Froese, biologist with GEOMAR | Helmholtz Centre for Ocean Research Kiel (Germany) and Dr Steven Martell, biologist with the University of British Columbia (Canada) have recently presented a new, much simpler method to estimate the MSY. This method...

Scientists from NOAA's National Marine Fisheries Service report a significant decline of endangered white abalone off the coast of Southern California in the journal Biological Conservation. "Since 2002, we have been surveying white abalone off San Diego using an underwater remotely operated vehicle (ROV)," said Kevin Stierhoff, research fisheries biologist at NOAA's Southwest Fisheries Science Center in La Jolla, and lead author of the journal article. "In the absence of fishing, we hoped...

Fatness Could Be Next Global Threat
2012-06-19 04:53:26

As people around the globe continue to get fat, researchers now say that gaining weight may be a bigger threat to global food resources than having an extra billion people. Researchers found that if the entire human population stepped on one massive scale, the weight would read 632 billion pounds. During the study, the team obtained information about the average body mass index of people in each country, and calculated the percentage of the population that is overweight and obese....

Scientists Concerned About Methane, Fishing In Arctic Ocean
2012-04-23 04:04:47

While some scientists encouraged the creation of regulations governing fishing in the Arctic Ocean on Sunday, others published a report warning that the body of water could actually be a significant source of the greenhouse gas methane. The latter team, lead by Eric Kort of the California Institute of Technology (Caltech), participated in a total of five flights to measure atmospheric methane levels in latitudes as high as 82 degrees north in 2009 and 2010, AFP reporters said. They...

Ecologists in New Zealand have shown for the first time that Marine Protected Areas — long advocated as a way of protecting threatened marine mammals — actually work. Their study, based on 21 years' monitoring and published today in the British Ecological Society's Journal of Applied Ecology, reveals that a marine sanctuary off the coast of Christchurch has significantly improved survival of Hector's dolphins — one of the rarest dolphins in the world. Covering 1170 km2 of...

Life deep in the seabed proceeds very slowly. But the slow-growing bacteria living many meters beneath the seafloor play an important role in the global storage of organic carbon and have a long-term effect on climate. A team of scientists from Aarhus University (Denmark) and the University of Rhode Island have developed a new method for measuring this slow life deep down in the seabed. According to URI Oceanography Professor Arthur Spivack, the relative abundance of amino acids that are...

Marine Protected Areas Prove To Be Vital Aspect Of Green Turtle Sustainability
2012-03-21 05:08:51

Ryan Parson for RedOrbit.com Some sea turtles appear to be reaping the benefits of government designated areas of bodies of water, known as Marine Protected Areas (MPAs). A recent study published in the journal Global Ecology and Biogeography suggests that the MPAs are playing a key role in the support and nourishment of the Green turtle. According to the National Marine Fisheries Service, all six species of sea turtles that inhabit US waters are currently listed under the Endangered...

Ocean Analysis for November 17, 2012
2012-11-17 08:24:58

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...

Ocean Current Impacts On Weather
2012-07-30 13:25:48

The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific are transported west to east and start to replace these colder waters. The Peru current is...
