A petition calling for the Granville Fishing Agreement to be revoked has reached 1,000 signatures.
Ministers will now have to respond to the petition.
The Granville Bay Treaty allows Jersey and French boats to fish within the Bay of Granville.
The petition organisers say the current agreement is unfair, as it favours France.
The treaty dates back to 19th century and was amended in 2000 to help improve fishing regulations between both France and Jersey.
Although the deal allows each country to access each other's waters, the Jersey fleet of around 75 registered vessels is far less than the hundreds of French boats.
Earlier in the year the Jersey Fisherman's Association said that the number of boats using the shared space has become too high and it is having an impact on stock levels.
