Taranaki fisherman slams government data on Maui’s dolphin

1477250734422A commercial fisherman in Taranaki has rubbished new government data which shows increased Maui’s dolphin numbers.  The research – conducted by the Department of Conservation and the Ministry of Primary Industries – found there are approximately 63 adults left in the species whereas there was previously thought to have been only 55.  New Plymouth fisherman Rob Ansley said claims by minister Nathan Guy that set net restrictions were having a positive effect on Maui’s numbers  was “a load of s**t”. Ansley said government observers aboard fishing boats in Taranaki waters had not seen a single Maui’s dolphin since they started observing in 2012.  “How can it be working if no one has ever had a confirmed sighting of these dolphins,” he said. According to the Department of Conservation the last confirmed sighting of a Maui’s dolphin in Taranaki was at Port Taranaki on January 18, 2014 while the last sighting in New Zealand was on March 20, 2016 off Muriwai beach in Auckland.  Read the story here 15:28

Recovery of Marine Mammal predators causes unexpected conservation challenges

In the paper, published in the journal Conservation Letters, scientists explored the effects of these recovering predator populations on their home ecosystems, outlining three major unintended conflicts that have resulted. In the Pacific Northwest the comeback of California sea lions and killer whales, as well as Pacific harbor seals (Phoca vitulina), all protected under the MMPA, has increased the animals’ competition with humans for fish. Furthermore, all three predators feed on the ESA-protected Chinook salmon (Oncorhynchus tshawytscha), whose populations are declining. And competition for fish among the predators could adversely affect them all. Read the rest here 10:40

NOAA recognizes Predator/Prey Relationship of exploding populations of Marine Mammal Populations and fish!

NOAA ScientistThe study by scientists from NOAA Northwest Fisheries Science Center and the University of Washington examines recovering predator populations along the West Coast of the United States and in the Greater Yellowstone ecosystem, and the conflicts surrounding them. The study was published today in the journal Conservation Letters. In the Pacific Northwest, for example, California sea lions that have increased under the Marine Mammal Protection Act have increasingly preyed on endangered salmon.,, Read the rest here 16:01

Stranded sea lions overwhelm California rescue centers

People in Marina del Rey, Calif., were surprised when a sea lion pup wandered into their apartment complex. But getting help for Walter when he was spotted last week wasn’t easy. Nearly 1,000 have washed ashore so far this year. The warmer water could have affected the availability of prey to the sea lions. Another possibility is “the sea lion population is reaching carrying capacity. Read the rest here 18:41

US Navy has rejected recommendations by the California Coastal Commission for its use of sonar and underwater explosives

In a letter July 31, the Navy said it disagreed with the commission’s determination that naval training plans did not include enough information to conclude the overall marine mammal count isn’t affected by sonar technology or by detonations at sea. The Navy is applying for a five-year renewal of its federal marine permit to conduct training over a huge swath of ocean between Hawaii and Southern California. [email protected]  08:24
