Mealworms safely consume toxic additive-containing plastic
Tiny mealworms may hold part of the solution to our giant plastics problem. Not only are they able to consume various forms of plastic, as previous Stanford research has shown, they can eat Styrofoam containing a common toxic chemical additive…
Consider marine life when implementing offshore renewable power
With countries such as Iceland, Costa Rica, New Zealand, and Norway adopting green energy practices, renewable energy now accounts for a third of the world’s power. As this trend continues, more and more countries are looking to offshore energy sources…

Scientists link decline of Baltic cod to hypoxia — and climate change
Fishes’ ‘internal logbooks’ show decline in valuable species is caused by loss of seawater oxygen
Study to help manage shark populations in Pacific Panama
Sharks play a critical role in keeping oceans healthy, balancing the food chain and ensuring species diversity. However, the demand for shark derivatives has led to their exploitation, often without appropriate management strategies in place. In an assessment of Pacific…
Scales offer insight into chronic stress of fish, University of Guelph research finds
For years, aquatic researchers have sought an easy way to determine when wild fish are under stress. Now University of Guelph researchers have shown for the first time that a key stress hormone, cortisol, accumulates in fish scales slowly and…

Squid pigments have antimicrobial properties
Ommochromes, the pigments that colour the skin of squids and other invertebrates, could be used in the food and health sectors for their antioxidant and antimicrobial properties. This is confirmed by the analyses carried out by researchers from the University…

Call for cooperation as ‘blue boats’ rob Pacific reefs
A flotilla of Vietnamese fishing boats with crews suffering in harsh conditions is stripping Pacific coral reefs of seafood as the poaching escalates to become an international human rights and security issue. Dr Andrew Song, joint ARC Centre of Excellence…

Female fish can breed a new species if they aren’t choosy about who is Mr. Right
Fish will mate with a species outside their own if the male’s colouring is attractive enough or if the female can’t see him properly, according to new research. Such ‘mistakes’ in mate choice can lead to the evolution of new…

Project to enhance shrimp and fish health in Bangladesh
Experts at the University of Stirling are working with senior industry, government and scientific officials from Bangladesh in a bid to tackle a major issue in the aquaculture sector. The Institute of Aquaculture (IoA) has developed a pioneering tool that…
Whaling and climate change led to 100 years of feast or famine for Antarctic penguins
BATON ROUGE – New research reveals how penguins have dealt with more than a century of human impacts in Antarctica and why some species are winners or losers in this rapidly changing ecosystem. Michael Polito, assistant professor in LSU’s Department…

Kelp farming on the west coast — Environmentally friendly aquaculture
There is a growing interest of the cultivation of macro algae. A new dissertation studies the best conditions for sustainable cultivation of the brown algae sugar kelp. The negative environmental effects of kelp cultivation is very limited, especially compared to…

Fish size affects snake river salmon returns more than route through dams
Research suggests juvenile bypass systems do not affect later ocean survival
The heat is on
nternational team of scientists complete the largest global assessment of ocean warming impacts
Meeting the challenges facing fisheries climate risk insurance
Insurance schemes with the potential to improve the resilience of global fisheries face a host of future challenges, researchers say. The world’s first “Fisheries Index Insurance” scheme, launched by an international consortium in July, is a sovereign-level instrument designed to…
Study tracks genomic changes that reinforce darter speciation
CHAMPAIGN, Ill. — When they share habitat, orangethroat and rainbow darters tend to avoid one another, even though they are closely related and can produce “hybrid” offspring. The males compete with males of their own species and will almost always…

Bacteria-infecting viruses bind mucosal surface and protect from disease
Mucosal surfaces protect organisms from external stressors and disease. Bacteriophages, viruses that infect bacteria, have been shown to preferentially bind to mucosal surfaces. This has been suggested to provide an extra level of immunity against bacterial infections. Researchers at the…
Leadership’s in the blood for tiny fish
Leadership during cooperation runs in the family for tiny fish called Trinidadian guppies, new research shows. University of Exeter researchers studied leadership in guppies by selectively breeding for fish that differed in how likely they were to lead a scouting…
