Bycatch has 'shocking' toll on British marine life, analysis reveals
The Devastating Impact of Bycatch on British Marine Life
Thousands of Britain’s most charismatic and protected marine wildlife, including whales, porpoises, dolphins, seals and seabirds are being killed as “collateral damage” by fishing vessels every year, according to the first-ever analysis of bycatch data.
The Scale of Bycatch
The analysis, by the Wildlife and Countryside Link, a coalition of voluntary conservation groups, reveals the devastating toll bycatch, the accidental capture and killing of non-target species by fishing vessels, is having on marine species.
- Over 1,000 harbour porpoises and common dolphins killed annually
- 10,000 seabirds killed annually
- 500 seals killed annually
- 6 humpback whales and 30 minke whales found dead in Scottish creel ropes
- Over 1,000 endangered Atlantic salmon and 120 tonnes of protected sharks, skates and rays caught and killed as bycatch by commercial fishing vessels every year
The Impact on Marine Ecosystems
The deaths estimated in the report, which were extrapolated from datasets on bycatch and discard numbers, were more than likely to be “the tip of the iceberg”, it said, as only a fraction of the UK fishing fleet monitor bycatch. Only 0.05% of dredging vessels monitor this. They, like the bottom trawlers exposed in the recent David Attenborough film Oceans, drag heavy gear across the sea floor and are known for doing damage to marine life on the sea bed.
Calls for Action
Richard Benwell, the chief executive of Wildlife and Countryside Link, said most of the deaths were avoidable by using a range of mitigation measures. He called on the government in England to deliver promised action on bycatch of protected species.
“From razorbills and dolphins to endangered salmon and sharks, the scale of destruction exposed in this report is shocking, with animals dying in awful and unnecessary ways.”
Solutions and Recommendations
The coalition is also calling on the government to require remote electronic monitoring on all fishing vessels operating in English waters, including small vessels under 10 metres that it said are responsible for a large proportion of bycatch.
While the study covered deaths in UK waters, the recommendations are largely targeted at the UK government in England, drawing on the expertise of WCL’s English members, the report said.
