Deep-water experiment reveals lobsters’ appetite for jellyfish
A team from Heriot-Watt University was surprised to find lobster scaring off other marine life in order to eat defrosted helmet jellyfish carcasses which has been attached to an underwater camera and lowered 250 metres in the Sognefjorden in western Norway. The experiment was designed to find out which deep-water species were most attracted by a jellyfish dinner, with hagfish and amphipods expected to be interested. But it was the Norway lobster – worth around £80 million to Scottish fishing catches – that was most keen and ate half of the jellyfish. click here to read the story 10:15

The surprising reason you might be seeing more jellyfish in the sea this summer
Scientists have discovered that offshore wind farms and oil and gas platforms provide an ideal habitat in which the creatures can thrive. Until now, the rapid increase in jellyfish numbers in oceans around the world has been largely blamed on overfishing, which wipes out their natural predators, global warming and nutrient run-off. The research suggests that man-made structures have played a role in the jellyfish boom by offering an enticing home for polyps — the tiny organisms which eventually grow into jellyfish. The results suggested a correlation between big jellyfish numbers and man-made structures such as energy platforms and wind farms. click here to read the story 13:41
Jellyfish Transformed into ‘Super-Absorbent’ Nappies and Tampons
A new method of transforming jellyfish into biodegradable “super-absorbers” suitable for use in nappies, sponges, paper towels and tampons has been developed by nanotechnology startup Cine’al. Read more here ibtimes.com 12:39
Jellyfish futures ring global ocean industry alarm bells
Those pretty translucent blobs that the word “jellyfish” conveys? Who’d have thought? Few of us know the half of it. Closer to home, jellyfish can massively sting salmon to death. They increase the ocean acidification that has ravaged our Northwest shellfish, eating away their shells. Pink jellies are abundant in late summer in Deep Cove’s Indian Arm. To say the least, jellyfish are bad for business. (Coincidentally, last week the Vancouver Sun’s Larry Pynn detailed the total collapse of B.C.’s sardine fishery but mentioned no role for jellyfish.) https://fisherynation.com/archives/16084 [email protected] 12:27
Jellyfish: It’s What’s For Dinner
The recent jellyfish pulse might thus be a snapshot within a long series of natural cycles,” Laura Poppick writes for the Monterey Bay Aquarium Research Institute. A recent study of jellyfish sightings from 1874 to 2011 conducted by MBARI suggests that the blooms follow a cyclical pattern, one that peaks every 20 years. The Research Institute’s sister organization, the Monterey Bay Seafood Watch, doesn’t issue a rating for the in Georgia or the other Southern states where jellyballs, as locals call them, are caught.
