The fish quota deal was signed in Brussels last month

The meeting comes after revelations that Scots fishing quotas are lower than at first thought.

Leader John Swinney is spearheading calls for an increase in fishing days, an end to the permit system and greater access to traditional haddock grounds.

Scottish Executive officials are currently locked in talks with the EU aimed at tidying up the deal.

Mr Swinney insisted that all of Scotland must "stand together" in a bid to redraw the deal for the nation's fishermen.

He said: "Every voice in the land should be raised in defence of our fishing industry.

"It faces a deal that spells bankruptcy while foreign boats are free to fish our traditional haddock grounds.

"That cannot be allowed to stand. That is the message we will take to the EU."

'Delicate position'

The SNP delegation includes Alex Salmond MP, Angus Robertson MP and MEP Ian Hudghton who are meeting the director general of conservation policy in Brussels on Monday.

The situation is becomingly increasingly urgent with only a matter of days before the quotas come into force.

The deal was signed in Brussels last month and has not been well-received by the fishing industry in Scotland which is worried for its future.

An executive spokesman said talks between the executive and the EU would continue this week.

He said: "The whole negotiations are predicated on our ability to demonstrate we can enforce any improved deal that is given to the UK.

"That leaves us in a delicate position with the negotiations, which will continue this week."

John Swinney will lead the SNP delegation in Brussels

On the home front, representatives of various fishing organisations will lobby Westminster MPs in a bid to save their industry.

They will seek financial compensation for fishing communities in a meeting with Fisheries Minister Ben Bradshaw.

They want him to push harder for pay-outs for areas affected by the recent changes.

They will also put pressure on Liberal Democrat leader Charles Kennedy to urge his party to join the Tories and SNP in supporting calls for a withdrawal from the EU's Common Fisheries Policy.

Campaigners will threaten to organise public meetings in his Ross, Skye and Inverness West constituency and disrupt his party's forthcoming European elections campaign.
