Cuba’s government enacted sweeping reforms to its fishing laws aimed at increasing protection for some of the world’s most important and vibrant marine ecosystems, while also ensuring a future for its fishers.

The new law, the first national change in more than 20 years, represents a major shift in Cuba’s current fisheries policy, the Environmental Defense Fund (EDF) said.

Declining fish populations have remained a serious problem for Cuba, putting the country’s food security, thousands of jobs and healthy ecosystems at risk.
