Abstract
Broodstock maturation diets are an important component of shrimp hatchery
management, since the nutritional status of spawners can impact on gonadal maturation,
egg fecundity, embryo hatchability and overall larval quality. The ability to manipulate the
biochemical composition of Artemia to deliver key nutrients to cultured animals has
rendered their inclusion in broodstock feeds increasingly common. Lipid enrichment of
Artemia to boost their highly unsaturated fatty acid (HUFA) content is a standard procedure.
During this study, frozen, lipid-enriched adult Artemia were fed to Lysmata amboinensis
broodstock to investigate the suitability of Artemia as maturation diet for the
species and elucidate the role of essential fatty acids (EFAs) in the reproductive performance
of the shrimp. Four lipid enrichment levels, un-enriched ("unenr"), 1/3 enriched
("1/3 enr"), 2/3 enriched ("2/3 enr") and enriched ("enr") Artemia, were fed to
L. amboinensis over three reproductive cycles. Spawning and egg mass retention during the
incubation period were high for all diets. Larval production varied, however, and was
significantly greater (P < 0.001) for L. amboinensis broodstock fed the "enr" Artemia
compared with the other treatments, with a mean 529 (±76.76) larvae, as opposed to 49
(±11.16) recorded for the "unenr". The increased larval production was attributed to better
embryo hatchability and related to an increased docosahexaenoic (DHA) dietary content of
11% (in total FAs) and a DHA/eicosapentaenoic (EPA) ratio of 3.6. The roles of other
EFAs are also discussed.
