“…Postlarvae fed enriched Artemia also presented higher weight at the end of the larviculture period. Although this corresponds well with previous findings demonstrating the positive effect of dietary n-3 HUFA in the enhancement of larval growth and development (Lèger & Sorgeloos, 1992;Rees et al, 1994; Cavalli et al, 2000;Palacios et al, 2004;Immanuel et al, 2007), it disagrees with studies where no effect of n-3 HUFA enriched Artemia were observed in the size of P. monodon (Rees et al, 1994) and F. paulensis postlarvae (Pontes & Andreatta, 2003) or where a negative relationship between dietary n-3 HUFA levels and postlarval length was observed (Martins et al, 2006). Differences between these studies may be due to various causes, including variations in experimental design, species, feed management, composition of the emulsions, postlarval size and age, or duration of the experimental period.…”

“…A positive effect of the provision of dietary n-3 HUFA to crustaceans is that it often results in higher stress tolerance (Tackaert et al, 1989;Dhert et al, 1992;Rees et al, 1994;Cavalli et al, 2000;Chim et al, 2001;Palacios et al, 2004;Immanuel et al, 2007;Sui et al, 2007). It is therefore recognized that penaeids fed n-3 HUFA deficient diets generally express a low tolerance to stress (Chim et al, 2001;Palacios & Racotta, 2007).…”

ABSTRACT. There has been a considerable amount of work on the effects of Artemia enrichment on shrimp larvae. However, the effects on the subsequent growth performance have not been thoroughly investigated. From mysis I to eight day-old postlarvae (PL8), shrimp (Farfantepenaeus paulensis) were fed either newly hatched Artemia nauplii or Artemia enriched with an emulsion containing high levels of n-3 highly unsaturated fatty acids (n-3 HUFA). Upon reaching PL8, shrimp were exposed to salinity and ammonia stress tests. Growth performance was assessed by further rearing shrimp for 40 days. Shrimp fed the enriched Artemia (named EG) had higher tolerance to both salinity and ammonia than those fed newly hatched Artemia (named CG). Weight of PL from EG was also significantly higher than in CG. Higher levels of n-3 HUFA, especially 20:5 n-3 and 22:6 n-3, were found in the enriched Artemia. In the postlarvae, higher levels of n-6 and n-3 HUFA were observed in EG, while PL from CG presented higher levels of 18:3 n-3 and 18:4 n-3. At the end of the nursery rearing, no differences in survival were observed, but weight was higher in EG (1.08 g) than in CG (0.90 g). The supplementation of n-3 HUFA during larviculture increases the tolerance of F. paulensis postlarvae to salinity and ammonia, and positively affects growth performance after a 40 days long rearing period.

“…Although Pacific white shrimp are generally tolerant of a wide range of salinities, the minimum salinity tolerance depends on strain (Saoud et al 2003), ionic composition of culture water (Zhu et al 2004;Davis et al 2005;Roy 2006), acclimation of postlarvae (Saoud et al 2003;McGraw and Scarpa 2004), diet and highly unsaturated fatty acids (Palacios et al 2004), and temperature (Tsuzuki et al 2000). Nonetheless, adding K þ to feeds of shrimp reared in inland LSWW does not seem to affect osmoregulation.…”

“…However, it could also be a result of the Artemia strain used, since different strains might present different retroconversion capacities, and of different enrichment methodologies, such as enriching twice, washing after the enrichment, light and temperature, etc. Using double enrichment and ICES emulsions with 9% DHA, we had previously obtained 13% of DHA in Artemia metanauplii (Palacios et al, 2004). Part of the DHA in EPAX could have been lost by oxidation during emulsification and enrichment, since it is not designed as commercial emulsion to be used dissolved in water.…”

“…It is well known that although DHA levels were high in the emulsions, they tended to decrease in the enriched metanauplii, probably a due to fatty acid retroconversion (Navarro et al, 1999;Han et al, 2001;Palacios et al, 2004). Since we wanted to further increase DHA levels supplied to juvenile seahorses, we used commercial oil designed for human consumption containing more than 60% of DHA, compared to 10-15% of DHA generally present in the emulsions designed for fish.…”

ABSTRACT. Survival during first months after birth is one of the bottlenecks for consolidating the seahorse farming industry. In this work, Artemia metanauplii enriched with two highly unsaturated fatty acids (HUFA) rich commercial emulsions with different docosahexaenoic acid (DHA) levels (63% and 14% of total lipids), a vegetable oil with no DHA, and non-enriched Artemia as control, were used to feed 5-day-old juvenile Hippocampus erectus for 60 days. Enriched Artemia had similar levels of DHA (13% and 9%), despite great differences of DHA in the emulsions, with traces of DHA in non-enriched and vegetable oil enriched Artemia. More than 20% of DHA was found in 24 h starved juveniles fed both DHA-enriched treatments, similar to values in newly born juveniles, but those fed vegetable oil enriched Artemia or non-enriched Artemia had 5% of DHA. Total lipid and protein levels were similar in juveniles from the four treatments. The n-3/n-6 ratio was almost four-fold higher in seahorses fed DHA-enriched treatments compared to juveniles fed the nonenriched treatments. Survival of seahorses only partially reflected the DHA levels: it was lower in the vegetable oil treatment, similar in the seahorses fed Artemia with higher DHA and in the control treatment, and higher in seahorses fed the HUFA-enriched Artemia with lower DHA levels, although growth was similar in the two DHA-enriched Artemia treatments. Juvenile H. erectus seahorses perform better when they have at least 20% of DHA in their tissues, and these levels can be attained with no more than 14% of DHA in emulsions, eliminating the need for more expensive emulsions with higher DHA levels.

La sobrevivencia durante los primeros meses de vida es uno de los cuellos de botella para la consolidación de la industria del cultivo del caballito de mar (Hippocampus erectus). En este trabajo se utilizaron metanauplios enriquecidos con dos emulsiones comerciales, con diferentes niveles de ácido docosahexaenóico (DHA) (63% y 14%), con aceite vegetal sin DHA, y metanauplios sin enriquecimiento como control, para alimentar caballitos de mar de 5 días de vida durante 60 días. La Artemia enriquecida tuvo niveles similares de DHA (13% y 9%), a pesar de las grandes diferencias en las emulsiones, con trazas de DHA en la Artemia no enriquecida y la enriquecida con aceite vegetal. Se obtuvo más de 20% de DHA en juveniles, muestreados con 24 h de ayuno, de los tratamientos con enriquecimiento de DHA, con valores similares a los de caballitos recién nacidos, pero los caballitos que se alimentaron con Artemia enriquecida con aceite vegetal y con Artemia no enriquecida tuvieron 5% de DHA. Los lípidos y proteínas totales fueron similares en los caballitos de los cuatros tratamientos. La razón n-3/n-6 fue casi cuatro veces mayor en caballitos alimentados con los t...
