Ocean acidification caused by human activities is likely to hit the Caribbean and west tropical Pacific regions the most.

Pacific islanders are at much higher risk of ciguatera fish toxins than previously thought, and the number of sufferers is increasing.

Traps that let juvenile and small fish escape have increased the sustainability of fisheries — without affecting fishers' livelihoods.

A new book on the vulnerabilities of Pacific island fisheries to climate change finds that although some will benefit more are at risk.

Scientists have calculated the minimum level of fish stocks that a coral reef needs in order to remain viable.

The ancient practice of farming fish in rice paddies benefits both parties, a study has found.

Climate change may shrink crops and animal food sources, damaging ecosystems and human livelihoods, warn scientists.

Implementing measures to reduce nitrogen and phosphorus runoff is key to controlling algal blooms, researchers say.

Spraying algal blooms with cheap, locally-available 'ball clay' forces them to the bottom of the sea, say researchers.

The key challenge with water is inefficient management, rather than scarcity, the World Water Congress has heard.

Mollusc fisheries in Haiti and several African countries are at most risk from increasing ocean acidification.

Seagrass beds as well as mangroves are vital nurseries for fish and should be conserved as interlinked habitats, a study finds.

Six programmes worth more than US$950 million, which will target the poor's access to food and markets, have been conditionally approved.

An award-winning project helps find local solutions to ensure sustainable and profitable fisheries in developing countries.

Global aquaculture must invest in knowledge-sharing if it is to reach its potential as a sustainable food supplier, says a report.

A marine biodiversity survey of Indian Ocean countries has revealed inadequacies on several levels.

Satellite sensing and other technologies could help poor countries minimise environmental damage from aquaculture, says a report.

Experts have proposed five catching regions in Northwest Mexican waters, which would improve fisheries management.

An improved yeast strain has boosted prospects for the production of biofuel from seaweed, but several technical challenges remain.

A study on small scale fisheries around the world has shown that community-based management works better than top-down governmental rules.
