Ocean acidification may contribute to global shellfish decline

Home

Since 2000, Sea Shepherd has maintained a strong, positive presence in the Galapagos Islands. From patroling the Marine Reserve stopping illegal fishing activities, to busting shark finners, to educating the local youth, Sea Shepherd carries out its mission of promoting ocean conservation using a wide range of methods and actions.The Galapagos is our line in the sand. If humanity cannot protect such a unique and diverse ecosystem, we will not be able to protect any ecosystem. The Galapagos is a challenge and battlefield for the effort to halt human greed and destruction. These Enchanted Isles are a UNESCO World Heritage Site and this means all of us have a responsibility to help protect them from illegal exploitation.

Ocean acidification may contribute to global shellfish decline

Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University's School of Marine and Atmospheric Sciences.

In one of the first studies looking at the effect of ocean acidification on shellfish, Stephanie Talmage, PhD candidate, and Professor Chris Gobler showed that the larval stages of these shellfish species are extremely sensitive to enhanced levels of carbon dioxide in seawater.

"In recent decades, we have seen our oceans threatened by overfishing, harmful algal blooms, and warming," said Gobler. "Our findings suggest ocean acidification poses an equally serious risk to our ocean resources." ... Read Full Article

Our oceans are an important part of earth ecology and many poor third world countries depend upon them just in order to exist from day to-day.Overfishing and pollution are the cause of the decline in fish stocks right around the world.What would our oceans look like if there were no fish? How many of the worlds poor in such a scenario would survive?.When if ever will something be done to correct matters before they become irreversable?.
