Farm salmon pose clear reproductive threat to wild gene pools
Farmed salmon show full reproductive potential to invade wild gene pools and should be sterilised - according to new research from the University of East Anglia (UEA).
Ninety-five per cent of world's fish hide in mesopelagic zone
An international team of marine biologists has found mesopelagic fish in the earth's oceans constitute 10 to 30 times more biomass than previously thought.
Competition breeds new fish species, study finds
Competition may play an important role during the evolution of new species, but empirical evidence for this is scarce, despite being implicit in Charles Darwin's work and support from theoretical studies.
Study of jaw mechanics shows tetrapods still fed underwater
A study of the jaws of one of the earliest known limbed vertebrates shows the species still fed underwater, not on land.
A battery small enough to be injected, energetic enough to track salmon
(Phys.org) —Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and around ...
Genetic chip will help salmon farmers breed better fish
Atlantic salmon production could be boosted by a new technology that will help select the best fish for breeding.
Baited video carries baseline data in Cockburn Sound
Annual surveys investigating fish assemblages within Cockburn Sound over six years have led to two important findings that have enabled effective monitoring of fish ecology in the face of proposed developments.
Over-demanding market affects fisheries more than climate change
Fisheries that rely on short life species, such as shrimp or sardine, have been more affected by climate change, because this phenomenon affects chlorophyll production, which is vital for phytoplankton, ...
Why some fish can't go with the flow
Have you ever been snorkelling or scuba diving on a windy day when there are lots of waves? Did you notice how much that flow of water against your body affected your ability to swim and control your movements ...
Trawling restrictions crucial to preserve biodiversity
A Western Australian study has found that restricting trawling to 20-40 per cent of fishing areas in Shark Bay can mitigate the long-term impacts of commercial trawling in the region.
Survey set to prove northern fish disease-free
A joint study about to begin will determine whether populations of freshwater catfish in the country's tropical and sub-tropical regions are free of the Edwardsiella ictaluri bacterium.
Distinctive flashing patterns might facilitate fish mating
Scientists have shown for the first time that deep-sea fishes that use bioluminescence for communication are diversifying into different species faster than other glowing fishes that use light for camouflage. ...
Species matters in a noisy world
Fish exposed to increased noise levels consume less food and show more stress-related behaviour, according to new research from the University of Bristol and the University of Exeter. However, the way fish ...
New invasive species breakthrough sparks interest around the world
A research breakthrough at Queen's University Belfast has sparked interest among aquatic biologists, zoologists and ecologists around the world.
