More than 90% of the world's marine food supplies are at risk from environmental changes such as rising temperatures and pollution, with top producers like China, Norway and the United States facing the biggest threat, new research showed on Monday.

"Blue food" includes more than 2,190 species of fish, shellfish, plants and algae as well as more than 540 species farmed in fresh water, helping sustain 3.2 billion people worldwide.

But not enough is being done to adapt to growing environmental risks, a study published in the Nature Sustainability journal said.

"Although we have made some progress with climate change, our adaptation strategies for blue food systems facing environmental change are still underdeveloped and need urgent attention," said Rebecca Short, researcher at the Stockholm Resilience Center and co-lead author.

Overproduction in the industry, which has driven the destruction of wetland habitats, has caused significant environmental damage but other "stressors" are also impacting the quantity and quality of blue foods.

They include rising sea levels and temperatures, ocean acidification, changes in rainfall, as well as non-climate factors like algal blooms and pollution from mercury, pesticides or antibiotics.

"Vulnerability caused by human-induced environmental change ... puts blue food production under a lot of pressure," said Ling Cao, professor at China's Xiamen University, who also co-wrote the paper.

"We know aquaculture and fisheries support billions of people for their livelihoods and their nutritional security."

China, Japan, India and Vietnam account for more than 45% of global landings and 85% of aquaculture production, and the study said reducing their vulnerability should be a priority. Small island nations that depend on seafood are also especially vulnerable.

Cao said a UN treaty on sustainable development in the high seas, signed in March, could enable stakeholders to act in the common interest when it comes to protecting blue food resources but other risks are on the horizon.

Nauru in the Pacific Ocean is at the forefront of efforts to mine ocean beds for metals, which environmentalists say can cause immense damage to marine life. Norway, another major seafood producer, also came under fire last week after announcing it would open up sea areas to mining.

"Ocean floor mining will have an impact on the wild fisheries population," said Cao. "Many scientists are now calling on governments to evaluate where they do ocean mining in order to minimize the impact."

A man was gored and seven others lightly injured on Tuesday, the second day of Pamplona's San Fermin festival in which thousands of people line the medieval city's narrow streets for the centuries-old tradition of running with bulls.

The man who was gored, identified only as being older than 25, was injured by a bull horn under his right armpit, a spokesperson for the city emergency services said.

"At this time, he is under observation but is in stable condition," she told reporters.

The seven others suffered bruises and contusions, some in the shoulder or head, Reuters reported.

In the festival's "encierros", or bull runs, fighting bulls are set loose in the streets and then race to reach the bullfight arena. Hundreds of aficionados, many wearing traditional white shirts with red scarves, run with them.

On Tuesday morning, one of the bulls stopped in the middle of his run, and charged the runners for several tense minutes.

The festival, which gained international fame from Ernest Hemingway's 1926 novel "The Sun Also Rises", lasts for one week in early July.

Participants are occasionally gored at the hundreds of such bull-running fiestas in Spain every year. Other injuries are common. At least 16 runners have lost their lives at the Pamplona festival down the years, the last in 2009.

As well as the morning bull runs and afternoon bullfights, the San Fermin festival features round-the-clock singing, dancing and drinking by revelers.
There are also religious events in honor of the saint.
