“…These ranges are similar to the optimum range observed in this study. Salinity is known to affect the standard metabolic rate of hatched larvae of many species through osmotic stress, and on larval growth performance by the energy consumption for osmoregulation [2,3,43,44]. The highest SAI at 26 psu is possibly better for YFT larvae to save energy expenditure due to osmoregulation.…”

“…Jensen et al (1998) highlighted that this “U-shaped” pattern could represent an adaptive mechanism to improve the energy use since it allows fish to maintain a low gill NKA when facing a wide salinity gradient. Recent studies indicated that echinoderms could endure wide salinity fluctuation by isosmotic intracellecular regulation (Diehl 1986; Talbot and Lawrence 2002; Yuan et al 2010) Osmoregulation can also be evaluated by measuring variation of Na + /K + -ATPase, with a variation trend likely indicating the operation of the ion transfer pump (Ostrowski et al 2011). The study showed that the NKA activity reach consistent to the control group at 3, 6, 24 h and the concentrations of coelomic fluid sodium ions at 6 and 48 h were accordant to the optimum salinity under salinity 18 psu.…”

Effect of acute salinity stress on ion homeostasis, Na+/K+-ATPase and histological structure in sea cucumber Apostichopus japonicus

BackgroundSea cucumbers (Apostichopus japonicus) are an imperiled fauna exposed to a variety of environmental condition such as salinity and studies are urgently needed to assess their effects to guide aquaculture efforts. The effects of acute salinity stress on coelomic fluid osmotic pressure, ion concentrations, the activity of Na+/K+-ATPase in respiratory trees and the histological variations were measured to evaluate the salinity tolerance of sea cucumbers.ResultsSignificant correlations in osmotic pressure were observed between coelomic fluid and ambient environmental salinity. In coelomic fluid, Na+ concentration was observed fluctuated during salinity 18 psu and the inflection point presented at the 6 h. The Na+/K+-ATPase activity in respiratory trees indicated the “U-shaped” fluctuant change and the change trend was opposite with the Na+ concentration. The ions (K+, Cl−) concentration decreased and showed the same tendency at salinity 40 psu with salinity 18 psu. The total coelomocytes counts and phagocytosis of coelomic fluid Na+/K+-ATPase activity indicated fluctuating changes under different salinity stress. Histological variation revealed a negative relation between decreasing salt concentration and tissue integrity. Tissue damages were significantly observed in intestines, muscles and tube feet under low salinity environment (18, 23 and 27 psu). The connective tissue in intestines of A. japonicus exposed to 18 and 23 psu damaged and partly separated from the mucosal epithelium. The significant variations occurred in tube feet, which presented the swelling in connective tissue and a fracture in longitudinal muscles under low salinity (18 psu). The morphological change of tube feet showed the shrinkage of connective tissue under high salinity (40 psu). The amount of infusoria in the respiratory trees decreased or even disappeared in salinity treatment groups (18 and 23 psu).ConclusionThe results inferred that osmoconformity and ionoregulation were seen in sea cucumbers, which contributed to understand the salinity regulatory mechanisms of A. japonicus under acute salinity stress.

“…(1987) analysed the effect of salinity, in combination with temperature, on egg development and later hatching rates. Studies on early overall development, survival, yolk sac absorption, biometric measurements and malformations have evaluated the salinity tolerances of marine larvae of pelagic species such as Atlantic red porgy ( Pagrus pagrus ) (Ostrowski et al. 2011), Japanese eel ( Anguilla japonica ) (Okamoto et al.…”

Assays carried out under laboratory‐controlled conditions revealed that eggs of Senegalese sole, Solea senegalensis Kaup 1858, incubated at 10, 18, 27 and 33 grams per litre (g L−1) reached their maximum hatching rates (above 80%) 48 h after incubation. In contrast, hatching was significantly delayed (24 h) and completely failed when the salinity was set at 5 and 0 g L−1, respectively. Newly hatched and early‐developing yolk sac larvae presented similar survival rates 3 days after hatching (DAH) when exposed to salinities of 10, 18, 27 and 33 g L−1. Larvae incubated at 5 g L−1 salinity died a few hours after hatching once they were released from their respective chorions. The notochord length was unmodified by salinity 5 DAH. Nevertheless, an overall lower myotomal height and a putative delay in the depletion of yolk sac were found in larvae reared at 10 g L−1. This anomaly in overall larval development became more pronounced with the occurrence (100% of analysed larvae) of mouth deformities and a lack of functionality under 10 g L−1 salinity. Transferring 2 DAH larvae from 33 g L−1 (exhibiting normal mouth development) to a medium with a salinity of 10 g L−1 had no effect on first feeding, weight and metamorphic index. Overall our results indicate the existence of a key time window (0–2 DAH) in which a salinity value higher than 10 g L−1 is required to achieve adequate mouth development and further functionality of larvae. The present work represents a valuable contribution to the sole industry, opening new possibilities in hatchery management practices.
