By Faimon A. Roberts, Advocate Florida Parishes bureau11 OCtober 2011 This year’s white shrimp harvest in the waters off Louisiana’s southeastern coast is significantly lower than in the past, forcing some people in the industry to look elsewhere for product and scale back operations while others blame the April 2010 Deepwater Horizon oil disaster. “I […]
By Seth Koenig, BDN Staff7 October 2011 SOUTH PORTLAND, Maine — They’re called dead muds. Rising levels of carbon dioxide in the atmosphere combined with unregulated nitrogen pollution are having a deadly effect on Maine’s shellfish, some researchers say. Scientists are starting to measure the impact of increasingly acidic waters on coastal organisms, and what […]
FORT WORTH, Texas, September 16 (AP) — Wading through a muddy river bed to reach shallow pools of water, wildlife biologists scooped up hundreds of minnows Friday in one of the first rescues of fish threatened by the state’s worst drought in decades. The scientists collected smalleye shiners and sharpnose shiners from the Brazos River […]
The pH of ocean waters has decreased by about 0.1 since preindustrial times. Each tenth of a pH point represents a tenfold change in acidity. Living corals begin to die off in acidic waters, and the calcium carbonate shells of mollusks, including some commercial shellfish, become weak, resulting in higher rates of mortality. Thirsty for […]
By John Burnett26 August 2011 The unfolding calamity that is the Texas drought has thrown nature out of balance. Many of the wild things that live in this state are suffering. Sections of major rivers — like the Brazos, the Guadalupe, the Blanco, Llano and Pedernales — have dried up. In many places, there aren’t […]
By Eric Scigliano18 August 2011 In the summer of 2007, something strange and troubling happened at the Whiskey Creek Shellfish Hatchery on Netarts Bay in Oregon, which raises oyster larvae for shellfish growers from Mexico to Canada. The hatchery’s “seed,” as the oyster larvae are called, began dying by the millions, for no apparent reason. […]
CHAUVIN, Louisiana, August 5, 2011 (ENS) – This year’s dead zone in the Gulf of Mexico is roughly equal to the land area of the state of New Jersey, scientists said this week. At 6,765 square miles, this area of low oxygen is the 10th largest on record and is considered about average for the […]
By Darryl Fears24 July 2011 A giant underwater “dead zone” in the Chesapeake Bay is growing at an alarming rate because of unusually high nutrient pollution levels this year, according to Virginia and Maryland officials. They said the expanding area of oxygen-starved water is on track to become the bay’s largest ever. This year’s Chesapeake […]
By Shelby Lin Erdman, CNN; CNN’s Ninette Sosa and Barbara Hall contributed to this reportJuly 18, 2011 (CNN) – Massive global greenhouse gas pollution is changing the chemistry of the world’s oceans so much that scientists now predict it could severely damage shellfish populations and the nations that depend on the harvests if significant action […]
ScienceDaily (July 14, 2011) — Ocean acidification, a consequence of climate change, could weaken the shells of California mussels and diminish their body mass, with serious implications for coastal ecosystems, UC Davis researchers will report July 15 in the Journal of Experimental Biology. California mussels (Mytilus californianus) live in beds along the western coast of […]
