SCUBA Fish Count

Silent divers count more fish

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 […]

European eel

Ship noise slows eels and lets predators catch them twice as quickly

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 […]

Tiger Shark

Shark loss hits global ecosystems

The loss of sharks could contribute to the destruction of one of the planet’s most under-appreciated sources of carbon storage — seagrasses, according to FIU researchers. Not that sharks eat the seagrass, they don’t, but they do eat the turtles which feed in the seagrass meadows. Add this to the problems of pollution, mooring and […]
