Bord Iascaigh Mhara or BIM (; meaning "Sea Fisheries Board") is the Irish state agency for developing the Irish marine fishing and aquaculture industries.
Originally established under the Sea Fisheries Act, 1952, the organisation provides resources to the fishing industry, particularly in aquaculture, as well as providing information and promoting seafood to consumers. Historically, it operated boatyards in Baltimore, Dingle, and Killybegs.
BIM headquarters is in Dún Laoghaire, County Dublin.
