The following experiments compared survival and growth of shrimp larvae fed Artemia nauplii beginning at either the protozoea 2, protozoea 3 or mysis 1 substage. Experiment one compared survival and growth of larval Penaeus setiferus , from the protozoea 2 substage to three‐day‐old postlarvae, fed algae and either freshly hatched Artemia nauplii, decapsulated Artemia cysts or ultraviolet killed Artemia nauplii beginning at the protozoea 2 or mysis 1 substage. Survival was better for those postlarvae fed all three Artemia food types beginning at the protozoea 2 rather than the mysis 1 substage. Post‐larval dry weights were similar, regardless of Artemia food type or the larval substage at which Artemia was introduced. Experiment two compared survival and growth of larval P. aztecus , from the protozoea 2 substage to two‐day‐old postlarvae, fed algae and live Artemia nauplii beginning at either the protozoea 2, protozoea 3 or mysis 1 substage. Controls were only fed algae. Survival was significantly better for those postlarvae fed Artemia beginning at the protozoea 2 substage. Post‐larval dry weights increased with the introduction of Artemia nauplii beginning at the protozoea 2 substage. The potential effects of these results on current hatchery procedures are discussed.
