A standardized bioassay is described for the nutritional evaluation of Artemia nauplii and metanauplii using juvenile Mysidopsis bahia. This test is particularly suited to evaluate the dietary value of different strains and batches of Artemia . One day starved, fed or enriched Artemia metanauplii can also be tested.For this test, a homogenous population of freshly-released juveniles (less or equal to 24h-old) were produced in a mysid generator-separator. The test animals were transferred into an experimental apparatus, cultured under standard conditions and offered Artemia ad libitum. After 12 days, data on survival, length, individual dry weight, and reproductive characteristics were recorded and treaded statistically.
