Populated Puget Sound sees stark shifts in marine fish species

The most populated areas of Puget Sound have experienced striking shifts in marine species, with declines in herring and smelt that have long provided food for other marine life and big increases in the catch of jellyfish, ...

Jellyfish blooms pulse cyclically through time

A surge in jellyfish blooms over the past decade has spawned similar blooms of public fascination with these sea drifters and their apparent saturation of our oceans. Images of fish nets and nuclear-plant intake pipes clogged ...

Norway lobsters' appetite for jellyfish caught on camera

Norway lobsters' secret love of jellyfish has been caught on camera for the first time, raising questions about whether jellyfish blooms are pests or potential food sources for the commercial fishing industry.

Unraveling jellyfish metamorphosis

How does one genome create two completely different body plans in one animal? This was the question Konstantin Khalturin was attempting to answer when he began working on jellyfish. The fascinating story he discovered along ...

'Trojan horse' effect may explain jellyfish blooms

(Phys.org)—Man-made structures such as harbours, tourist facilities, oil rigs and aquaculture farms provide ideal sanctuaries for jellyfish polyps to flourish and may explain an apparent increase in jellyfish blooms in ...

UBC researchers use drones to track jellyfish blooms

Jellyfish blooms are becoming more widespread and scientists are looking for ways to understand them better, including their impact on species like salmon that compete with them for food sources. Now, researchers at the University ...

Distinctive body type aids long life and predation

Jellyfish (Cnidarian medusa) have unique body plans that violate a universal law of biology and facilitate their longevity and their propensity to form blooms, according to an international study involving UWA scientists.

Predicting jellyfish 'invasions' at coastal power stations

Scientists at the University of Bristol are working with the energy industry to develop an 'early warning tool' to predict the sudden, en masse appearance of jellyfish swarms which can cause serious problems by clogging the ...

Global experts question claims about jellyfish populations

Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations – clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants – and ...
