Peaceful sharks

IUCN update finds sharks increasingly threatened

The Lost Shark, Carcharhinus obsoletus, is already extinct, and others that are expected to follow soon include four species each of hammerhead and angel sharks, from the world’s most threatened shark families. In spite of all the press that shark conservation has received in the past two decades, no effective protection of sharks has been established, no sharks have been saved, and their decline into extinction is ever more apparent.

Appeal to Shark Lovers!

The paper presents the reasons why large predators of great ecological importance cannot supply the rising demand for shark fins, which is driven by profits that rival the drug trade and involves the fisheries of nations around the globe. They have essentially run out of fish so are targeting sharks now that the shark fin trade has made them valuable.

Sharks at risk from quest to develop vaccine against corona virus

Development of a vaccine against Covid-19 could come at the expense of sharks, researchers warn; A key ingredient used in vaccines to enhance immune response and increase effectiveness, squalene — an oily substance found in plants and even human skin — is particularly concentrated in shark livers.

Commercial fishing banned in Yangtze River for 10 years

The Chinese government has imposed a 10-year commercial fishing ban in the Yangtze River to combat "across-the-board" declines in the populations of rare species like the Chinese sturgeon.

As it came into effect on 1 January 2020, it is hoped that the ban will tackle the problems of dwindling fish stocks and declining biodiversity in the 6,300m river. It will be applied at 332 conservation sites along the river and be extended to cover the main river course and key tributaries by 1 January 2021.

Rescuing Seals in Vladivostok

The larga is the spotted seal (Phoca largha) that lives in the North Pacific Ocean along the coasts of South Korea to Chukotka in Russia, and from Alaska to California in the United States. These seals choose coastal rocks in shallow bays for their rookeries. In winter time, larga seals spend a lot of time on ice near ice holes, or on floating ice floes along the coast. These seals feed on fishes, octopuses and shellfishes.

Californian whale populations stable or improving

Blue and fin whales are common inhabitants of the Southern California Bight, but little is known about their use of the area. To study their distribution, high-frequency acoustic recording packages were intermittently deployed at 16 locations across the bight from 2006 to 2012. Blue whale calls were more common at coastal sites and near the northern Channel Islands, while the fin whale call index was highest in the central and southern areas of the bight, indicating a possible difference in habitat preferences of the 2 species in this area.

Florida Manatees: Sirenians of Crystal River

A winter’s dawn is a special time to be on Kings Bay, for as the first rays of the Florida sun appear over the horizon, they light up the soft mist on the warm waters of the bay and create an ethereal, almost mystical, feeling. Listen carefully and you will hear the gentle ripples from the swirl pools formed by the paddle-like tails of the sirenians, as they make their way towards the freshwater springs that are the source of Crystal River.
