In what was probably the largest Thanksgiving feast this week, a swarm of billions of jellyfish attacked a salmon farm in Northern Ireland yesterday and ate $2 million worth of fish. Jellyfish and slime are taking over the oceans, just as Dr. Jeremy Jackson always warns. Billions of jellyfish feasting on more than 100,000 salmon, just another shifting baseline.

That's smuck, not schmuck. And it's the official term for a swarm of jellyfish, according to Jonathan in the last jellyfish post. The name was just created in 2000 (the need for a name for a swarm of jellyfish, just another shifting baseline). Apparently, after wiping out Northern Ireland's only…
Yesterday, from Seafood.com News:
Scientists are criss-crossing the Irish Sea on ferries, counting stinger jellyfish which are blamed for wiping out salmon stocks...Scientists suspect global warming is the principal cause of the jellyfish shoals...The Natural Environment Research Council has given…
Three shifting baselines to note today:
1) An article in today's New York Times by Andrew Revkin discusses how "scientists are setting baselines to gauge future effects on the seas." The article is a nice summary of some of the latest attempts to document the decline in ocean health even if it's…
Overfishing, eutrophication, acidification, and climate change are leading to what Dr. Jeremy Jackson describes as the rise of slime in the oceans. For some recent evidence, check out this invasive algae in Crystal RIver or this recent story about increase in jellyfish on the Jersey shores.…
That is distinctly scary: like science fiction or a biblical plague.
Do you have a new banner today? The font looks like Gill Sans.
Mind, Cardigan Bay and the Irish Sea have long been a good hunting ground for jelly lovers like Mabel

Is the latest swarm a sign of possible "trophic cascade" in this area, or is it just one of those things - what do you think?
As a former Jellyfish researcher, and a current fisheries scientist, I should point out that the fish weren't eaten, but succumbed to the stings and mucus that large blooms will inflict. Pelagia noctiluca is a very small animal by jellyfish standards (Typically a few cm across the bell, up to 10cm) and like most jellyfish, they are planktivores. Having been stung by this species as a graduate student, I can imagine that the effect of so many would have given the fish no chance of survival.
In our changing ocean ecosystems, jellyfish blooms are certainly an increasing hazard worthy of study,but talk of 'feasting on' salmon conjures up B-movie images that detract from the real threats. Sorry to be a stickler! :) Keep up the good work.
P.S. - At the 1st International Conference on Jellyfish Blooms in Gulf Shores, Alabama, in 2000, we discussed the word "Smuck" as the proper collective noun for jellyfish :)
Finally, a simple solution to the problem of open net fish farming!
Jonathan. Good point. Feasting they were not. I should have said 'attacking' but I got hung up on the Thanksgiving theme. We have a new student with the Sea Around Us Project who will be looking a lot at jellyfish blooms globally so I should have more details about increases soon! As for the banner, yes it is new and indeed replete with Gill Sans. What do you think?
Oh, that's really cool. I'm glad there's more folks looking at it these days, as it's a really important field. Feel free to send them my way should they want to bounce any ideas around. I'm not sure if you the administrator can see the email addresses, but I'm at Simon Fraser!
I'm going to bet that it's usually the first reason that gets most peoples' knickers in a twist. In this culture, women's bodies exist mostly to please men. If they're otherwise occupied, or not pleasing, they're supposed to be kept private. The breasts of breastfeeding women are both--no wonder they're so offensive.
The authors found that the frequencies of allergic and IgE-associated allergic disease and sensitization were similar in the children who had received probiotic and those whoâd gotten placebo. Although there appeared to be a preventive effect at age 2, there was none noted at age 5. Interestingly, in babies born by cesarean section, the researchers found less IgE-associated allergic disease in those who had received the probiotic.
