Invasion Of The Oversized Crustaceans! Asian Tiger Shrimp Invade The US
2012-04-27 07:16:15

Giant cannibal shrimp are invading the coasts of America en masse -- and while it sounds like the work of a mad scientist in one of those cheesy, low-budget, black-and-white 1950s science-fiction movies, the danger (or rather, lack thereof) is all too real. U.S. Geological Survey (USGS) and National Oceanic and Atmospheric Administration (NOAA) researchers have discovered that there were more than 10 times as many sightings of Asian tiger shrimp, which can grow to be more than a foot long...

8 Species Of Wild Fish Have Been Detected In Aquaculture Feed
2012-04-25 08:16:41

Researchers from the University of Oviedo have for the first time analyzed a DNA fragment from commercial feed for aquarium cichlids, aquaculture salmon and marine fish in aquariums. The results show that in order to manufacture this feed, eight species of high trophic level fish have been used, some of them coming directly from extractive fisheries. Aquaculture initially came as an ecological initiative to reduce pressure from fishing and to cover human food needs. However, a problem has...

Scientists Find Higher Concentrations Of Heavy Metals In Post Oil Spill Oysters From Gulf Of Mexico
2012-04-19 08:18:55

Comparisons between pre- and post-spill specimens show an increase in vanadium, chromium, cobalt, and lead concentrations in shells, gill, and muscle tissue As the two-year anniversary of the Deepwater Horizon oil spill in the Gulf of Mexico approaches, a team of scientists led by Dr. Peter Roopnarine of the California Academy of Sciences has detected evidence that pollutants from the oil have entered the ecosystem's food chain. For the past two years, the team has been studying oysters...

Ocean Acidification Linked With Larval Oyster Failure in Hatcheries
2012-04-13 03:43:11

Increase in ocean acidification led to collapse of oyster seed production at Oregon hatchery Marine researchers have definitively linked the collapse of oyster seed production at a commercial oyster hatchery in Oregon to an increase in ocean acidification. Larval growth at the hatchery declined to a level considered by the owners to be "non-economically viable." A study by the scientists found that increased seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean...

Researchers at Oregon State University have definitively linked an increase in ocean acidification to the collapse of oyster seed production at a commercial oyster hatchery in Oregon, where larval growth had declined to a level considered by the owners to be “non-economically viable.” A study by the researchers found that elevated seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean water, inhibited the larval oysters from developing their shells and growing...

Ancient Civilizations Reveal Ways To Manage Fisheries For Sustainability
2012-03-24 03:06:20

In the search for sustainability of the ocean's fisheries, solutions can be found in a surprising place: the ancient past. In a study published on March 23 in the journal Fish and Fisheries, a team of marine scientists reconstructed fisheries yields over seven centuries of human habitation in Hawaii and the Florida Keys, the largest coral reef ecosystems in the United States, and evaluated the management strategies associated with periods of sustainability. The results surprised them....

The windowpane oyster, Placuna placenta, alternatively known as capiz, is a bivalve marine mollusk belonging to the family Placunidae. Among the species within the genus, only the P. placenta has an outer shell that is sufficiently translucent for commercial use. This mollusk can be found from the shallows of the Gulf of Aden, to around India, then Malaysia to the southern South China Sea, and around the Philippines. Capiz, a province in the Philippines, gets its name from this shell which...
