Vietnam Shrimp Farmers Suffer from Uncontrolled Expansion, Gov’t Vows Enforcement on Antibiotics

SEAFOODNEWS.COM [ Vietnam News Brief Service] January 5, 2016 — Authorities in the Mekong Delta, the biggest aquatic pond in Vietnam, are striving to tighten control over local shrimp farming toward sustainable way amid rising concerns on antibiotics contamination, disease outbreak and polluted environment.

Tran Quoc Tuan, director of the Industry and Trade Department of Tra Vinh province, said he supported efforts to tighten the management of antibiotic use in shrimp farming and boost dissemination of information to farmers and processing companies.

He said state management agencies still have to make farmers aware of the risks, and companies must change their way of doing business by co-operating with farmers to build clean material areas. In doing so, the seed, farming methods, feeding and medicines will be strictly controlled in order to produce quality products, he said.

Profitable shrimp farming produced a rapid transformation in the quality of life for Vietnamese people in the Mekong Delta region, but the unplanned expansion in production has also had negative effects on the environment and domestic shrimp trade.

Due to its favorable natural conditions, farmers in coastal communes of many Vietnamese southern provinces started to switch from rice cultivation to shrimp farming 15 years ago. The rapid success and high income that the industry ushered in pushed many local people to invest in this sector.

Due to attractive profits, farmers in other areas of unfavorable natural conditions also did whatever it took to raise shrimp. Farmers spontaneously drilled wells to bring in salt water and made ponds to raise shrimp.

The rapid growth of shrimp farming and poor infrastructure has led to disease outbreaks, massive shrimp death and huge losses for farmers in many places.

Many farmers in Ben Tre, Bac Lieu, Kien Giang and Tra Vinh have been forced to give up shrimp farming as shrimp disease broke out.

Meanwhile, a large volume of Vietnamese seafood, including shrimp, has been rejected by importing countries. According to statistics of relevant agencies, in the last two years, 32,000 tons of Vietnamese seafood, mainly shrimp were not allowed to enter foreign markets because of antibiotic contamination.

In the first nine months of 2015, 38 foreign countries returned 582 batches of seafood products to Vietnamese providers for the same reason, stating that they would tighten the inspection of shrimp shipments from Vietnam.

There are various types of antibiotics displayed for sale, but farmers are mostly unaware of their toxicological effects. On the other hand, processing factories keep buying shrimp without proper inspection, so farmers become negligent in utilizing antibiotics.

Mass. public may be unaware of striped bass contaminants

November 10, 2015 — Anglers are perched on Massachusetts’ shores long into the cold weather, fishing for fare that often lands on their dinner tables: Striped bass.

But what they may not know is the striped bass they catch in state marine waters may contain high levels of toxins that make eating too much harmful to one’s health, especially for pregnant women and children.

Massachusetts is the only state on the East Coast that does not specifically mention striped bass in its fish consumption advisories. While some states issue broad blanket advisories, especially for pregnant women and children, others offer warnings not to eat too much of striped bass from specific water bodies.

Connecticut, Maine, and New Hampshire all recommend that children as well as women who are nursing, pregnant, or may become pregnant not eat striped bass at all. Some states in New England warn the general population not to eat more than a maximum of between 4 and 12 meals per year of striped bass caught in state waters. Rhode Island has the most stringent advisory, urging striped bass not be eaten at all.

Mercury emissions down but mercury in Mass. fish remains high

July 19, 2015 — MASSACHUSETTS — Mercury emissions from major Massachusetts sources have declined by 90 percent over the past two decades, but mercury levels in the state’s freshwater fish hold stubbornly high, with many species too contaminated for pregnant women and children to eat.

Yet languid summer days and the lure of Massachusetts’ 3,000 freshwater bodies – from the Berkshire’s Lake Pontoosuc to Boston’s Jamaica Pond – send many anglers casting for a good fish dinner.

The inability to reduce mercury in fish to safe eating levels troubles environment and health officials – and added to that concern is growing evidence that some freshwater fish in similar northern latitudes, from the Great Lakes to Scandinavia, appear to have increasing mercury levels after years of decline. The New England Center for Investigative Reporting found six studies in the past decade that point to increasing mercury levels in freshwater fish.

“We need to figure out what is going on,’’ said Michael S. Hutcheson, former head of air and water toxics for the Massachusetts Department of Environmental Protection who retired last month. Reducing emissions in Massachusetts certainly helped – some freshwater fish near closed incinerators and other mercury sources showed a 44 percent decline in mercury levels – but the difficulty in getting further reductions speaks to a more complex problem, he said.
