Genetic key to salt-tolerance discovered in tilapia fish

Most fish live either in fresh water or salt water, but others, including tilapia, have the remarkable ability to physiologically adjust to varying salinity levels—a trait that may be critically important as climate change ...

Acidification and low oxygen put fish in double jeopardy

Severe oxygen drops in the water can leave trails of fish kills in their wakes, but scientists thought adult fish would be more resilient to the second major threat in coastal waters: acidification. A new study published ...

Fish type, body size can help predict nutrient recycling rates

The nutrients excreted by fish in their "pee" may be critical to the health of coastal ecosystems. But knowing whether generalizations can be made about how to predict these nutrient levels in various ecosystems has vexed ...

Salish Sea seagull populations halved since 1980s

The number of seagulls in the Strait of Georgia is down by 50 per cent from the 1980s and University of British Columbia researchers say the decline reflects changes in the availability of food.

Jellyfish exterminator robot developed

A team led by KAIST Civil and Environmental Engineering Department's Professor Hyeon Myeong has just finished testing the cooperative assembly robot for jellyfish population control, named JEROS, in the field.

Conducting cool summer research in the Arctic

The Arctic Coastal Ecosystems Survey (ACES) is focused on understanding the ecological role of near-shore and lagoon habitats of the Chukchi and Beaufort Seas that surround Alaska and its connectivity with the coastal ocean. ...

Boom in jellyfish: Overfishing called into question

Will we soon be forced to eat jellyfish? Since the beginning of the 2000s, these gelatinous creatures have invaded many of the world's seas, like the Japan Sea, the Black Sea, the Mediterranean Sea, etc. Is it a cyclic phenomenon, ...
