American Lobsters were first hatched and successfully reared in a laboratory in ~1850. However, these efforts have always required live or frozen foods such as Artemia. Researchers at the New England Aquarium have successfully incorporated commercial formulated Artemia replacement diets as 50% of a larval American lobster diet.
Combination diets of either live Artemia nauplii or frozen adult n-3 fatty acid enriched Artemia with a rotation of three commercial formulated diets resulted in equivalent survival to stage IV (19–25%), postlarval size and subsequent early juvenile performance compared to an Artemia nauplii plus frozen Artemia combination diet. A 100% formulated diet resulted in reduced larval survival (6%) and postlarval size, while a larval diet of 100% frozen adult Artemia resulted in reduced postlarval quality and early juvenile performance.
The much lower price of the formulated diets compared to the prices of Artemia nauplii and frozen Artemia makes its inclusion in the lobster larval diet the most cost-effective diet choice.
