Bretagne Grands Migrateurs (BGM) is a non-profit organisation approved for the protection of the environment that contributes to the restoration and management of migratory fish populations in Breton rivers and their environments.
BGM coordinates migratory fish actions in Brittany and implements assessment and facilitation tools such as the Migratory Fish Observatory in Brittany. BGM works closely with several scientific, technical, institutional and financial partners to provide technical and administrative support.
BGM disseminates information on migratory fish through its website, semimonthly newsletters and an annual summary of the actions undertaken.
BGM’s active members are the 4 departmental federations for fishing and protection of aquatic environments (FDAAPPMA) of Brittany.
