In the last 60 years the fishing industry have caught nine out of every ten large fish. That’s only 10% of large fish like tuna, cod, swordfish and halibut remaining on the planet. International fleets still pursue what is remaining. According a 2014 report by the United Nations Food and Agriculture Organization, over 90% of […]
SCUBA divers underestimate the amount of life in heavily-fished areas, a study suggests. Scientists from Australia compared fish counts by SCUBA divers—who produce noisy bubbles—and divers using silent rebreathers. They found little difference in counts between the two in Marine Protected Areas (MPAs), where the fish weren’t frightened of the divers. In more heavily fished […]
Eels are losing the fight to survive when faced with marine noise pollution such as that of passing ships, according to a study published in the journal Global Change Biology. Scientists from the Universities of Exeter and Bristol that found that in the presence of ship noise, European eels (Anguilla anguilla) were 50% less likely […]
For the first time, Britain’s Royal Mail has issued stamps championing an environmental issue – and that issue is over-fishing.
Fish living in deep waters on the continental slope around the UK play an important role carrying carbon from the surface to the seafloor. It has been assumed that deep water fishes all depend on particles that fall from the surface for their energy. These bottom-living deep water fishes never come to the surface and […]
The massive Conger Eel grows to almost 3 m (10 ft) long, the females often being bigger than the males. At night they hunt fish and crustaceans like crabs and lobsters. In spite of this divers often see crustaceans sharing a hole with a conger. Congers breed only once in their lives, at between 5 and 15 years of age. They migrate to deep water to spawn – some sources say as deep as 4000 m.
Marine conservationists have launched a smartphone app in the hope of discovering new information about some of the ocean’s most mysterious and threatened animals — seahorses — and paving the way for similar efforts with other difficult-to-study species. With iSeahorse Explore, anyone can contribute to marine conservation with a few taps of their phone. The […]
If you have dived in the Red Sea, Indian or Eastern Pacific Ocean, you will probably have seen shoals of these small black fish. They live on coral and rocky reefs at depths of 1 to 55 m. Do not rely on the name for identification. When young, the threespot dascyllus does indeed have three […]
A large mouth, eyes set high on the head and its tufted tentacles above each eye give the Tompot Blenny (Parablennius gattorugine) a comical appearance. A much smaller fringed tentacle is positioned on the nostril beneath each eye.
The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers at the University of California, San Diego, have found. The tail’s exceptional flexibility is due to its structure, made up of bony, armored plates, which slide past each other. Researchers are hoping to use a similar structure […]
