“…Increased survival seen at the juvenile stages suggests that by this stage L. vannamei develops increased osmoregulatory capacity as has been reported for other decapod crustaceans 4 . PL size has been indicated to be indirectly correlated to a larger gill area, which in turn is thought to represent a better osmoregulatory capacity 1 . From the results of our study, although PL20 could tolerate salinities as low as 2 ppt, highest survival of nearly 95% was achieved at 5 ppt, showing that it would be preferable to keep endpoint salinity at not less than 5 ppt in the ISPS system, in order to achieve maximum survival rates.…”

Low salinity rearing of Litopenaeus vannamei requires the transfer of postlarvae (PL) from high salinity hatchery systems to low salinity conditions. In order to determine effective transfer methods, fifteenday-old postlarvae (PL15) were acclimated from a salinity of 30 ppt to endpoint salinities of 1 and 5 ppt using single-step and gradual salinity reduction procedures. Higher survival rates were obtained with gradual acclimation than with single-step acclimation. Survival of PL15 acclimated to 5 ppt was better than that of PL15 acclimated to 1 ppt. Survival of PL15 and juvenile stages in various low salinity treatments ranging from 0-5 ppt was also compared. In the PL stage, survival rates were good (>85%) in salinities over 1.5 ppt. Tolerance to low salinities increased with age and survival rate of juveniles (65%) was higher than that of PL (2%) in freshwater. In our long-term growth trials of juvenile shrimp maintained in different salinities, optimal growth comparable to that in normal seawater was observed in animals reared in a salinity of 5 ppt, demonstrating that L. vannamei can be successfully cultured in low-salinity inland systems.

“…Furthermore, shrimp fed n-3 HUFA rich diets have larger gill area , which concurs with the more ramified gill structure reported in n-3 HUFA fed P. monodon postlarvae (Rees et al, 1994). Although stress tests have been commonly used as a tool to compare the quality of crustacean larvae and juveniles in terms of tolerance to a number of physical and chemical parameters (Tackaert et al, 1989;Samocha et al, 1998;Cavalli et al, 2000;Chim et al, 2001;Álvarez et al, 2004;Martins et al, 2006;Immanuel et al, 2007;Sui et al, 2007), to date few studies have attempted to correlate the results of stress tests with the posterior growth performance of shrimp. In this regard, Bauman & Jamandre (1990) reported that batches of P. monodon postlarvae that responded positively to a salinity stress test presented a comparatively superior growout performance in ponds.…”

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.

“…Differences in the source and condition during broodstock management can result to great variability in the egg and larval quality. Various criteria have been used to evaluate the egg, larval and post-larval quality of crustaceans (Alvarez, Racotta, Arjona & Palacios, 2004;Bauman & Jamandre, 1990;Cavalli et al, 2000;Ikhwanuddin, Hayimad, Ghazali, Halim & Abdullah, 2016).…”

Quality assessment of newly hatched mud crab, Scylla serrata , larvae

Starvation and exposure to formalin were investigated as possible stress tests for evaluating the quality of mud crab, Scylla serrata, larvae. For the starvation stress test, newly hatched zoeae stocked in 150-ml containers were either starved or fed rotifers. Similarly, newly hatched zoeae were stocked in containers with seawater of 0 (control), 20, 30 and 40 mg/L formalin for the formalin stress test. The zoeae from the same batches were used for seed production to monitor their performance and validate the results of stress tests. Starvation was found to be unsuitable for larval quality evaluation. However, the impact of initial food deprivation on the newly hatched larvae indicates that feeding immediately after hatching is necessary for mud crab larvae. Exposure of larvae to 40 mg/L formalin for 3 hr appeared to be a reliable and practical method for larval quality assessment as the survival of larvae in the mass production tanks validated the classification of good and poor quality batches in the stress tests. On this basis, a hatchery operator can decide which batch should be cultured further. Finally, there appears to be a link between the quality of larvae and the performance at the megalopa and early juvenile crabs.
