Seabirds are at risk due to the competition they face from the fishing industry for food, a new study has claimed.

There has been a 70 per cent decline in seabird populations over seven decades due to a combination of the fishing industry, pollution and habitat destruction.

Scientists - University - Aberdeen - Timeframes

Scientists from the University of Aberdeen looked at two timeframes - 1970 to 1989 and 1990 to 2010.

They assessed the degree of competition seabirds faced for their favourite foods - species such as anchovy, sardines, mackerel, squid, krill and crustaceans.

Team - Consumption - Species - Types - Seabird

The team then estimated the annual consumption of these species for 276 different types of seabird species.

They based this on population counts and models, which they compared to annual catches by fishing boats recorded in the Sea Around Us world database.

Experts - Seabird - Consumption - Millions - Tonnes

Experts found that the total annual seabird consumption decreased from 70 to 57 millions of tonnes between 1970 to 1990 and 1990 to 2010.

Annual fishery catches increased from 59 to 65 million tonnes over the same period.

Dr - Aurore - Ponchon - Study - 'Our

Dr Aurore Ponchon, who co-led the study, said: 'Our research shows, that despite the decline of the world seabird community between 1970 to 1989 and 1990 to 2010, competition with fisheries remained sustained.

'This competition was even enhanced in almost half the oceans. This enhanced competition.

Addition - Factors - Pollution - Predation - Species

'In addition to other factors such as pollution, predation by invasive species on chicks, the destruction and changes in their habitat by human activities and environmental changes caused by climate change, puts seabirds at risk, making them the most threatened bird group, with a 70 per cent decline over the past seven decades.

'This study calls for an improved management of the world's fisheries to alleviate...
