| This paper describes the first results of a study on the effects of broodstock nutrition on reproduction in marine crustaceans. For this, a short-term test system has been developed with the estuarine mysid shrimp <i>Mysidopsis bahia</i> (M.) as experimental animal. Three different <i>Artemia</i> preparations were evaluated for their possible effects on reproductive activity and offspring quality: a commercial maturation diet (Marila) incorporated in Great Salt Lake <i>Artemia</i> metanauplii was compared to freshly-hatched nauplii and coconut-oil enriched metanauplii as food sources for the experimental broodstock animals. Within an experimental period of 14 days after reaching sexual maturity, 3.4 respectively 8.8... |

| The importance of essential fatty acids for the early larval stages of cultured marine fish and crustacean larvae is well documented. In this regard, the variability in essential fatty acid content of their live prey <i>Artemia</i> is critical.This paper describes different techniques for improving the fatty acid profile in <i>Artemia</i> nauplii using microparticles and emulsions as enrichment diets. These diets can be applied during the incubation of the cysts and/or after the separation of the nauplii. After enrichment, the nauplii not only contain high levels of the essential fatty acid 20:5 omega 3 (up to 13.5% or 35.2 mg/g) but also considerable levels of 22:6 omega 3 (up to 7% or 18.1 mg/g), another essential fatty acid which... |

| A standardized bioassay is described for the nutritional evaluation of <i>Artemia</i> nauplii and metanauplii using juvenile <i>Mysidopsis bahia</i>. This test is particularly suited to evaluate the dietary value of different strains and batches of <i>Artemia</i> . One day starved, fed or enriched <i>Artemia</i> 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 <i><i>Artemia</i> ad libitum</i>. After 12 days, data on survival, length, individual dry... |
