Effects of different food items on the culture of the mysid shrimp Mysidopsis almyra (Crustacea: Pericaridea) in a static water system.

Abstract

The effects of several food items on larvae production and survival ofthe mysid Mysidopsis almyra were compared. A total of sixdiets were used. The diets were: 1) phytoplankton (Isochrysisgalbana), 2) an artificial diet (Liqualife®, Cargill,Minneapolis, MN), 3) a mixed diet composed of both zooplankton (mostlycopepods)and phytoplankton, 4) 750 mg g−1 of HUFA enrichedArtemia nauplii and 250 mgg−1 of the artificial diet, 5) newly hatchedArtemia nauplii (24-hour incubation at 28°C) and 6) newly hatched Artemia naupliienriched with HUFA (SELCO®, INVE Inc., Ghent, Belgium) for 12 hours. Mysidsfed HUFA enriched Artemia nauplii (diet 6) had the highestproduction and survival rates, although not significant (P > 0.05), comparedto diets 3, 4 and 5, while the phytoplankton and the artificial diet hadsignificantly lower production and survival rates (p > 0.05).
