Hatchery Assistants’ primary responsibilities are to assist our Hatchery Technicians in the daily operation of our hatchery.

Duties will include cleaning and maintaining tanks/equipment and carefully following our Standard Operating Procedures (SOPs)/checklists. Hatchery assistants are expected to carry out daily tasks with an attention to detail and a reliable work ethic. In the hatchery offseason, August – December, Hatchery Assistants will learn about the other work on the farm by working with our grow-out operations team to farm our oyster leases on the Damariscotta River. The timing of this offseason work may vary based on the needs of the hatchery and the farm.

We can train the right person who has an interest in the work we’re doing, a positive attitude, and a great attention to detail. Hatchery Assistants should have no aversion to manual labor and work that is dirty in nature. This is a great opportunity to learn more about large-scale oyster farming!
