“…A significant number of marine teleosts utilize estuaries as nursery ground in their early life history, and inevitably encounter brackish waters. Those species develop low-salinity tolerance by the interplay of prolactin and thyroid hormone activities (Hiroi et al 1997), lower standard metabolic rate and an increase of food intake (Boeuf and Payan 2001). Clupeoid fishes, such as Sprattus fuegensis inhabit coastal waters of Chilean and Argentinean Patagonia (Sánchez et al 1995;Bustos et al , 2011 and its early life stages may be adapted to tolerate low salinity waters, partially explaining lack of correlation between ROGI index and salinity in larval S. fuegensis (Fig.…”

In fjord systems, freshwater inputs occur by ice melting and river discharge, affecting seawater salinity along fjord and adjacent waters, and potentially the ecology of early life stages of marine fish occurring in the area. During austral spring 2008, a bio-oceanographic cruise was carried out in southern Chile between 47°00′ and 50°09′S, an area influenced by Baker River discharge and ice melting of Northern and Southern Ice Fields, the largest glaciers from Patagonia. Surface salinity and temperature ranged from 1.22 to 32.80, and from 8.11 to 10.68°C, respectively. Larval lightfish Maurolicus parvipinnis (Sternoptychidae) and Falkland sprat Sprattus fuegensis (Clupeidae) were the dominant species, with abundances of 2.2-39.9 larvae 10 m −2 and 3.4-77.1 larvae 10 m −2 , respectively. Postflexion stages of both species were collected mainly in surface density fronts. Otolith-based growth analyses estimated linear growth rates of 0.136 mm day −1 for M. parvipinnis of 4.1-15.1 mm, and 0.448 mm day −1 for S. fuegensis of 5.4-20.5 mm. Recent Otolith Growth Index (ROGI), based on the residual analysis of the relationship between increment width of outermost five microincrements and otolith radius, indicates that larval M. parvipinnis collected in low salinity waters showed a reduction of its recent growth rate compared those collected in saltier waters. Also, ROGI was positively correlated with salinity of the water column for larval M. parvipinnis. Gut content analysis showed that large larvae collected near sources of freshwater had lower number of prey in its guts and preyed on different items than fish larvae collected in saltier waters. Therefore, freshwater inputs from rivers and glaciers from Patagonia affected horizontal distribution, recent growth and feeding of larval fish in fjords and channels of southern Chile.

“…Kikuchi et al (2007) found that the final body weight and length of the tiger puffer, Takifugu rubripes, were significantly higher at 10 ppt. The higher growth at lower salinity (15-20 ppt) was attributed to the slower metabolism, increased feed intake, protein digestibility and hormonal stimulation (Beuf and Payan, 2001). Partridge and Jenkins (2002) reported that at 24 ppt salinity, specific growth rate, food conversion efficiency and food intake of juvenile black bream, Acanthopagrus butcheri, were superior.…”

The status of aquatic environmental parameters like dissolved oxygen, pH, temperature, salinity and alkalinity etc. were examined in the six ponds located at Khar Land Research Station Farm at coastal district Raigad, Maharashtra, India in relation to fish culture. The study was conducted for two years 2005-2006 and 2007-2008. In the first year, the dissolved oxygen ranged from 4.95 mg/l to 5.75 mg/l; pH 8.1 to 8.6; temperature 24.5°C to 25.5°C; alkalinity 47-142.4 mg/l; salinity 2.5-10 ppt; nitrite-nitrogen 0.25-0.27 mg/l; nitrate-nitrogen 0.29-0.35 mg/l; phosphate 0.045-0.10 mg/l while in the second year, dissolved oxygen was in the range of 4.38-5.46 mg/l; temperature 25.3°C to 28.2°C; pH 7.43-7.58; salinity 11.41-21.66 ppt. The investigation revealed remarkable fluctuation in parameters like alkalinity and salinity. The wide fluctuation recorded in pond salinity indicated the suitability of water for culture of euryhaline fishes.

“…When the salinity level is varied from 25.36 to 25.9, environmental salinity may be closer to the isotonic point of the clamworms, and they show a good growth trend. If the clamworms are cultivated at a lower or higher salinity environment in which the salinity level deviates greatly from the isotonic point, the clamworms have to use a lot of energy to regulate the osmotic pressure and maintain a stable internal environment; thus, the energy used for metabolism, growth, and other life activities is reduced [26]. Thus, low or high salinity will inhibit the growth of P. aibuhitensis.…”

“…The energy clamworms use to perform osmotic regulation is mainly provided by the body lipids and proteins, so salinity can also affect the behavior, feeding, and immunity of clamworms [26]. Thus, the combined effects of salinity on the physiological functions of clamworms determine changes in their body fat and protein contents [24].…”

In this study, the effects of different salinity levels (9,12,15,18,21,24,27,30, and 33) on the growth performance, body composition, antioxidant indexes of Perinereis aibuhitensis (initial average mass, 20.4 ± 0.3 mg) and total nitrogen in the substrate were investigated. The survival rate, specific growth rate, feed coefficient, and protein efficiency ratio under different salinity levels were measured. The results showed that the survival rate of P. aibuhitensis at the salinity level of 9 was significantly lower than that of P. aibuhitensis at other salinity levels (P < 0.05). However, the survival rate of P. aibuhitensis at other salinity levels was not significant (P > 0.05). On the basis of quadratic polynomial fitting of the relationship between salinity levels and the specific growth rate, feed coefficient, and protein efficiency ratio, it was concluded that 25.36 -25.9 is the most suitable salinity range for the growth performance of P. aibuhitensis. The main body composition (moisture, crude fat, crude protein, and ash content) was measured at different salinity levels. The results indicated that, with the increase in salinity, the moisture content of P. aibuhitensis decreased gradually; in contrast, the ash content increased gradually, as the salinity level increased. However, in the salinity range of 18 to 33, the difference in ash content was not significant (P > 0.05). Salinity had a significant influence on the crude protein content (P < 0.05), while it had no significant influence on crude body fat. Crude protein showed an increasing trend with the salinity increasing from 9 to 24, and decreased with the salinity increasing from 24 to 33. Antioxidant indexes such as superoxide dismutase, catalase, vo MDA content was as low as the antioxidant activity at the salinity level of 24; this means low in vivo contents of active oxygen free radicals and excellent growth performance. This conclusion is consistent with that for other growth indexes. The total nitrogen content of the substrate in which the P. aibuhitensis specimens were cultured for 60 days was higher than the total nitrogen in the soil. With an increase in salinity, the total nitrogen content first decreased and then increased, and the lowest value was observed at the salinity level of about 24.
