European fishery chiefs are continuing their long drawn out yearly haggle over fishing quotas.
Ministers met during the night in the hope of striking a compromise deal.
This year the focus is as much on the amount of fish that gets thrown out as on what can be caught.
Environmentalists say 40 to 60 percent of all fish caught at sea are discarded, either because they are not the right size or fishermen do not have the quota to keep them.
The EU commission has proposed a complex set of technical rules to let unintentionally-caught fish escape from nets. But, Scottish fishermen said the regulations will hit them particularly hard.
With a deal expected later today, ministers will be aiming to strike the familiar balance between protecting stocks and safeguarding livelihoods.
