Dungeness crab die-off underway along US West Coast
An important species of crab found primarily along the West Coast is fighting off a combination of stressors that experts at the North Atlantic and Atmospheric Administration say has fishermen finding piles of dead shellfish, and the impacts are affecting the economy. Dungeness crabs are typically found along water beds, and their harvest can be worth a quarter-billion dollars annually. NOAA Fisheries believes the combination of a lack of oxygen, harmful algal blooms, water temperatures and ocean acidification are playing a role in the animal’s disappearance. >click to read< 16:12
In the Peconic Estuary, A Perfect Storm Hits Bay Scallops
Warming water temperatures, hypoxia (a deficiency in oxygen), ocean acidification, and harmful algal blooms, said Christopher Gobler of Stony Brook University’s School of Marine and Atmospheric Sciences, are each a stressor to the bivalve and local delicacy. The occurrence of more than one at one time, he said, may be responsible for the die-off (may be) ,,, The bay scallop fishery is “notorious for booms and busts,” Stephen Tettelbach, >click to read< 08:04
A collaborative approach to Chesapeake Bay restoration

Despite successful pollution reduction efforts, excessive nitrogen, phosphorus and sediment from runoff also still contribute to harmful algal blooms, “dead zones” and loss of underwater grasses. continued @ tidewaternews.com
