Use of commercial Artemia replacement diets in culturing larval American lobsters (Homarus americanus).

摘要

This work reports on the successful incorporation of 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.
