Scottish fishing leaders have warned a fair deal is vital as the second round of EU and Norwegian talks begin.
Some of the initial process in November was described as "appalling" by Scottish Fisheries Secretary Richard Lochhead.
Total allowable catches of stocks such as North Sea haddock, cod, whiting and herring are now to be addressed.
The Scottish Fishermen's Federation said the results of the talks were of the "utmost importance" to the fleet.
Bertie Armstrong, chief executive of the SFF, said: "At the most recent EC Fish Council just last week, we had to swallow the bitter pill of a bad deal being reached for the west coast of Scotland.
"Such scenarios must not be allowed to happen again during these final rounds of negotiations.
"Over the coming weeks, the SFF will be making every effort to influence the process and ensure that the best possible deal is achieved for the industry and the communities it supports."
