| Abstract | 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 Mysidopsis bahia (M.) as experimental animal. Three different Artemia preparations were evaluated for their possible effects on reproductive activity and offspring quality: a commercial maturation diet (Marila) incorporated in Great Salt Lake Artemia 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 times more juveniles were produced in the Marila- Artemia treatment than in the coconut-oil Artemia and freshly-hatched Artemia treatments respectively. The offspring quality in terms of resistance to temperature shock and starvation was also best with the Marila treatment. This study confirms that one of the factors determining the quality of the diet for marine crustacean broodstocks, is the content of omega3-highly unsaturated long chain fatty acids. |
