“…Although the differences were not statistically significant, the results were informative because the weight gain attained at 4‰ (coefficient of variation 0.40) salinity was almost half of that obtained at 32‰ (coefficient of variation 0.16). Laramore et al (2001), Walker et al (2009), andMaicá et al (2012), also in a system without water exchange, likewise recorded higher weight gains for both L. vannamei postlarvae and juveniles maintained at high salinity (at 30, 28 and 25‰, respectively), than at low salinity (at 4, 2 and 2‰, respectively). Furthermore, Perez-Velazquez et al (2012) reported a reduced value of weight gain of the referred species post-larvae reared in a water temperature of 24 ºC, at salinity of 4‰ and with a Na + :K + ratio of 120 (514.0%), compared with that of 40 (1,212.8%).…”

-The objective of this study was to evaluate the effect of salinity on the culture water quality, performance and body composition of Litopenaeus vannamei juveniles (1.16±0.30 g) reared for 36 days in a super-intensive system without water exchange at salinities of 4, 16 and 32‰. Groups of 200 animals (140/m 2 ) were stocked, with three replicates, in nine fiber-cement tanks (1.11 × 1.29 × 0.70 m) with a useful volume of 400 L. Physical and chemical parameters of water, such as temperature and dissolved oxygen before and after midday, pH, alkalinity, total suspended solids, total ammonium nitrogen, nitrite, nitrate, and phosphate, were monitored. Performance parameters like survival, weight gain, specific growth rate, feed conversion ratio and protein retention rate, were also evaluated. The proximate composition of the juveniles was analyzed through the moisture, protein, lipid and ash contents. The physical and chemical parameters of the water were influenced by the treatments. The increased salinity produced a significant increase in the alkalinity and the concentrations of total suspended solids, nitrite and phosphate. Of the parameters that were examined to evaluate the performance and proximate composition of the shrimp, only survival, protein retention rate and body lipid content were significantly influenced. The highest values were found at a salinity of 32‰. However, the analysis of the proximate composition of the bioflocs showed that the moisture, protein and lipid contents increased as the salinity decreased. Growth, use of feed and survival of L. vannamei juveniles reared in a super-intensive system without water exchange is positively influenced by an increase of salinity from 4 to 32‰.

“…However, ambient salinity fluctuates continuously because of changes in survival conditions, such as rainstorms or excessive freshwater, disappearance of dominant species of plankton, water pollution, high evaporation and natural episodic fluxes of freshwater input into estuaries from meteorological events (Christensen et al, 1997;Pan et al, 2006). It significantly affects the shrimp's ecophysiological performance (Walker et al, 2009). How L. vannamei adapts to the salinity fluctuations is vital to research.…”

“…The bodyweight specific oxygen consumption and ammonium excretion rates of other animals, including shrimps and fish, generally slightly exceed those of sea cucumbers (Beamish 1964, Bray et al 1988, Cai & Summerfelt 1992, Carvalho & Pham 1997, Mukai et al 1989, Walker et al 2009, Weymouth et al 1944) perhaps due to the sedentary and inactive nature of sea cucumbers. In polyculture of shrimp and sea cucumber where shrimp is the main commodity with much higher stocking biomass, the impact of sea cucumbers on oxygen consumption and ammonium excretion to the system would be minor compared to that of shrimp.…”

The oxygen consumption rate (OCR) and ammonium excretion rate (AER) of a tropical sea cucumber, Holothuria scabra, were determined in laboratory experiments. OCR and AER exhibited a significant negative correlation to body weight (BW), expressed as a power function of BW: OCR = 0.09 × BW −0.58 (mgO 2 /g/h, r 2 =0.89, n=15) and AER = 0.38 × BW −0.19 (μmolN/g/h, r 2 =0.54, n=15). These values were comparable to those in previous studies on other sea cucumber species. The OCR of shrimp tank sediment was reduced to less than half (4.5 ± 0.3 to 1.0 ± 0.1 mgO 2 /gdry/h) by the ingestion and excretion process of H. scabra. Acid volatile sulfide (AVS-S) concentration was also decreased to less than half (0.67 to 0.31 mgS/mgdry); despite the low reduction rates of organic carbon and nitrogen contents (0.19 to 0.14 mgC/mgdry and 0.022 to 0.019 mgN/mgdry, respectively). These results suggest that components in the sediment with high oxygen consumption potential were removed by H. scabra. These findings also provide fundamental information with which to evaluate the quantitative role of H. scabra in polyculture with shrimp.
