The town is preparing to fill the newly created position of herring superintendent. The person selected for the volunteer, part-time post will oversee the town’s herring commission and work to ensure the town’s herring run is managed properly, according to Town Administrator Edwin Thorne. The superintendent will also be asked to conduct public outreach to inform residents about the herring run, the water route in town that alewife follow when they migrate during their annual spawning season. The commission was formed by selectmen about 15 years ago, but the appointment of the superintendent — who will report directly to selectmen — formalizes the town’s herring run program, Thorne said. About a dozen people have applied for the position. Town officials are reviewing the applications, and the board is expected to act on an appointment this month.
