Primary Industries says the number of offers it has received for surrender of fishing licences makes it unlikely any compulsory acquisitions will be needed.

The voluntary process was undertaken due to extension of marine parks off South Australia and the further fishing restrictions which will result.

The department said it had received more than 100 submissions.

Fisheries executive director Mehdi Doroudi said compensation details would be made available in letters to be sent out in about a month.

"We definitely have been satisfied with the number, there are six different sectors that are affected in this process and that's over subscription of course for the number that we would need to remove, which is approximately around 24 licences," he said.

"We should be in a position to say how many of those sectors we have been able to through this first round, address and remove the displaced catch and effort and from there we can make a decision that do we require to go through a second round or any further work that needs to be done?"
