Proposes fishery rule could prevent tens of thousands of unnecessary whale and dolphin deaths
FRISCO — The National Marine Fisheries Service wants to boost global efforts to protect marine mammals with a new set of proposed rules that would require commercial fishing operations in other countries to meet U.S. standards.
As proposed, seafood imports from other countries could be banned if they don’t meet those requirements. Scientists estimate that each year more than 650,000 whales, dolphins, and other marine mammals are caught and killed in fishing gear. These animals are unintentional “bycatch” of commercial fisheries and either drown or are tossed overboard to die from their injuries.

Seismic airgun blasting, naval warfare training are key sources of harmful ocean noise pollution
FRISCO — With ever more offshore oil and gas exploration proposed, conservation advocates have been warning that the cumulative effects of those activities will take a huge toll on dolphins, whales and other marine life.
Lack of enforcement seen as stumbling block to recovery
FRISCO — Mexico has launched a last-ditch effort to protect the critically endangered vaquita porpoise by banning the use of gillnets in the northern Gulf of California. Conservation advocates said the ban is a step in the right direction, but expressed concern that Mexico won’t follow through with enforcement.
Vaquitas, the smallest members of the porpoise family, live only in the northern Gulf of California, generally in the vicinity of the Colorado River delta. The species has been on the Endangered Species List since 1985. Scientists say less than 100 individuals remain. Vaquitas could be extinct by 2018 without drastic conservation and recovery actions.
FRISCO — Germany’s largest travel agency and tour operator has announced that it won’t be offering any more trips to destinations that keep whales and dolphins in captivity.
TUI Deutschland officials made the decision after aligning themselves with an advocacy group that has highlighted just a few of the problems faced by captive cetaceans, including tiny enclosures and disruption of social structures.
TUI also cited information from the CNN documentary Blackfish, which is set to air once again on Feb. 9. The company also said it won’t offer trips to destinations that advertise swimming with dolphins, according to the German publication Die Welt.
While facilities like SeaWorld and other marine parks see themselves as good stewards of marine mammals, public pressure is growing to end the practice of showing whales and dolphins for entertainment.
German wildlife advocates said recent worldwide attention on the gruesome dolphin slaughter in Taji also helped push the huge tour operator toward the decision.

FRISCO — Dolphins exposed to heavy doses of oil from the Deepwater Horizon disaster are experiencing lung disease at five times the rate of dolphin populations in other areas, federal researchers reported in a new study published this week. The scientists also found that 25 percent of the Barataria Bay dolphins were significantly underweight and the population overall had very low levels of adrenal hormones, which are critical for responding to stress.
Results suggest that Florida coastal waters have high levels of the toxic metal
By Summit Voice
SUMMIT COUNTY — A new study by researchers from The Johns Hopkins University and The National Aquarium shows that wild dolphins have higher levels of mercury than their captive cousins, suggesting that mercury pollution in the oceans is a continuing problem.
The captive animals were fed a controlled diet, while the wild mammals dined on marine life that may carry more of the toxic metal.
The study found lower levels of mercury in the captive animals, particularly compared to wild dolphins tested off the Atlantic and Gulf coasts of Florida, a state that is in the path of mercury-laden fumes from power plants. The aquarium dolphins are fed smaller fish from North Atlantic waters, where mercury pollution is less prevalent. Continue reading “Oceans: Study tests dolphins for mercury exposure”→
