Feeding the killer whales

The San Juan Islander reports that half a million healthy juvenile Chinook salmon were released into the Salish Sea as part of the South Vancouver Island Anglers Coalition (SVIAC) and the Pacific Whale Watch Association (PWWA)'s "Feeding Our Endangered Orcas Initiative." The fish were delivered to Sooke, B.C.
This multi-year program is intended to significantly increase large adult Chinook salmon in the Juan de Fuca Strait during the key pre-winter feeding time of local killer whales.
The Southern Resident Killer Whales - J, K and L pods are endangered. Lack of food is one of the issues believed responsible for their declining numbers. Pollutants and noise from vessels are other top reasons for their decline according to NOAA.
Last year 225,000 healthy Chinook salmon smolts were successfully released from their temporary holding enclosure in the Sooke Basin and are expected to return as large adults in 2020.
In the future, increased quantities of Chinook smolts will be out planted each spring working towards an annual target of 2,000,000 smolts per year.

Some good news this week about the Irrawaddy dolphins of the Mekong River. A joint report from the Cambodian government and the World Wildlife Foundation tells how, following decades of seemingly irreversible decline, the population is increasing. They report the number of dolphins in the region has risen from 80 to 92 in the past two years—the first increase since scientists began keeping records more than twenty years ago. The first official census in 1997 estimated that there were 200 Irrawaddy dolphins in the Mekong, a figure that fell steadily due to bycatch and habitat loss. By 2015, only 80 dolphins remained. The recent census showed that more dolphins are surviving into adulthood, and there’s been a significant drop in overall deaths. Nine calves were born this year, raising the number of dolphins born in the past three years to 32. Seng Teak, Country Director of WWF Cambodia, said the census had positive implications for the Greater Mekong region, wher...

A blue whale spotted in Tasmanian waters - only the eighth sighting in six years

There have only been eight blue whale sightings in southeast Tasmanian waters in the last six years so the Marine Conservation Program was naturally a little bit excited this week.

The blue whale in the red sea

Huge Blue Whale Sighted in the Red Sea for the First Time | Smart News | Smithsonian : "On Tuesday morning, a fisherman off the coast of Eilat, Israel spotted something unexpected: a huge whale swimming along in the Red Sea. Experts were even more surprised to discover that the creature was a blue whale—marking the first time that the world’s largest mammal has been seen in the Red Sea, as Zafrir Rinat and Almog Ben Zikri report for Haaretz. Two days after it popped up in Israeli waters, Egypt’s environment ministry announced that the animal had also been sighted in the Red Sea’s Gulf of Aqaba, according to Aham Online. The ministry revealed that the whale measures 24 meters (nearly 80 feet) long, and belongs to a subspecies known as the pygmy blue whale. Monitoring teams in the South Sinai and the Red Sea have been deployed to track the whale’s movements." 'via Blog this'
