The good news, Allam says, is that the threats of both a harsh environment and QPX disease can be offset by selective breeding. With such significant economic consequences, defeating QPX has been a high priority for aquaculture researchers. Marked by chipped shell edges, the disease causes swelling and discoloration of the clam’s body wall and, in fact, can be fatal to the bivalve. They are the most important marine resource in several states, including New York, Virginia and Florida.īut over the years, growers have suffered setbacks during disease outbreaks and heat waves.įor example, QPX (“quahog parasite unknown”) disease was first observed in Canada in 1959 and has since ravaged farms in Massachusetts, Virginia, New Jersey, New York, Nova Scotia and Prince Edward Island. Hard clams in particular, which are also known as quahogs, are extensively cultured along the Atlantic coast. aquaculture, according to the National Oceanic and Atmospheric Administration (NOAA). ![]() Still, clams rank second among the most valuable species in U.S. “It’s really a contrast,” says Allam, attributing the decline to market constraints and natural mortality, like predation and disease. Department of Agriculture (USDA), the number of hard clams sold declined more than 10 percent between 20, while that of Eastern oysters shot up almost 60 percent. According to the Aquaculture Census of the U.S. While oyster farming has been thriving, harvests of hard clams have faltered. He says this latest collaboration among five states and international stakeholders promises to finally yield “superior clam stocks.” Bassem Allam of Stony Brook University in New York.Īllam follows years of studies on how to reverse the shrinking clam populations along the Eastern Seaboard. “It is 97 percent drafted,” says lead researcher Dr. Stony Brook, NY, JA consortium of scientists is on the brink of completing a genomic map of the hard clam, Mercenaria mercenaria, in an ongoing offensive against QPX disease and the effects of extreme heat. By Lynn Fantom Published in Hatchery International - May / June 2020 His new research involves collaborators in five Atlantic states in the US, as well as contributions from Canada, France, and the UK.
