“…These results have conformed to many studies, [21] has mentioned that the gradually transfer of grass Carp Ctenopharyngodon idella to the salt concentrations of 4, 8,12g/l led to increasing PCV [22] has referred that the sudden transfer for Barbus sharpeyi to salts 10.9, 12,5g/l and gradual transfer to the salt 7.1, 9.1 and 10.9g/l led to increase the PCV, referring that the increase of environment salinity caused increasing in taking Sodium by RBC that being formed a hyposmotic environment, in comparison with the external environment, causing swelling the in RBC, which reflected on increasing of PCV and plasma dryness [23]. [24] noticed an increase in the PCV of Acanthopagrus latus when exposed to different salt concentrations after 24 hours of exposure, the main reasons are related to the lose water from blood owing to increasing in osmosis differences between the blood and external environment. [25] has reached to the same result and given reasons for increasing PCV in the first stages of acclimation to the salt water that are related to the change in water content in the blood owing to the change in salinity of environment.…”

This study was conducted to investigate the effect of high salinity on the blood parameters of common carp (Cyprinus carpio) which gradually exposed to salt concentrations of 5, 10 and 15g/liter, as well as tap water (control 0.1g/liter). 80 fish were randomly distributed to four salinity treatments with 2 replicates /treatment (10 fish / replicate) at average weight of 15 ± 3 g to study the effect of salinity on the blood parameters, which included packed cells volume(PCV), red blood cells (RBC), white blood cells (RBC) and hemoglobin (Hb). Results showed an increase in the (PCV) to 36.17, 40.15 to and 45.30% when the salinity increased to 5, 10 and 15g/l respectively, compared with the control treatment (33.14%). Hb reached 13.34, 14.56 and 15.80 mg/100 ml at the concentration of 5, 10 and 15 respectively, compared with the control treatment (12.15 mg/100ml). RBC reached 2.80, 2.93 and 3.1 × 10 6 cells/mm 3 respectively, in comparison with control (0.1 g/l), while the WBC increased to 12.88, 15.23 and 10.55 × 10 3 cells/mm 3 when the salt concentrations were 5, 10 and 15g/l respectively, compared with control (10.44 × 10 3 cells/mm 3 ).

“…Negative effects were noted on fish growth, reproduction, survival rates, metabolism, and immunity when saline-alkali fluctuations exceeded its osmoregulation capacity (Sultan & Ahmed, 2014;Shi et al, 2023). Furthermore, these variations can have an effect on the performance of fish, the quality of their flesh, and the overall production in the field of aquaculture.…”

The impact of adding cortisol and thyroxin hormones was examined in the present study in the grass carp "Ctenopharyngodon idella (Val., 1844)" diets on some physiological and nutritional parameters during salt acclimatization. Seven diets with the same nitrogen and caloric content were prepared: one control diet vs. six experimental diets. Grass carp (24.80± 2.01g) were obtained from the Aquaculture Unit in the College of Agriculture-University of Basrah. Fish were maintained under laboratory conditions (salinity= 1.3g/ l) for one week in plastic aquaria. Fishes were fed twice daily on feed containing 35% protein with a feeding rate of 3% of their body weight. Grass carp were acclimatized to the target salinity of 10g/ L by the addition of sea salt. The growth parameters showed that weight gain was recorded at the highest value in T7 (5.22g), which was significantly different (P≤ 0.05) from the other treatments (3.93, 3.53, 4.02, 4.08, and 4.38 for T2, T3, T4, T5 and T6, respectively), while the lowest value was noted in the control treatment. The same trends were found for relative growth rate (RGR), specific growth rate (SGR), daily growth rate (DGR), and feed conversion ratio (FCR). The effects of thyroxin and cortisol hormones on sodium ion in blood plasma indicated a significant (P≤ 0.05) decline in all treatments compared to the control treatment in the first day of transportation and continued to the 10 th day in treatments T3, T4, T6 and T7. Similarly, a significant (P≤ 0.05) effect was found for thyroxin hormone in potassium ion in blood plasma in treatments T2, T3, and T4 with control treatment from the first day of transportation in 10g/ l salinity, while for the cortisol hormone, a significant (P≤ 0.05) decline was detected in treatments T6 and T7 start from the first day and continued to the 10 th day in treatment T7 compared to the control treatment. Sodium and potassium ions concentration in the muscles showed no significant (P> 0.05) differences among all treatments with the control treatment on the first day, but a significant (P≤ 0.05) decline in the 10 th day in some treatments compared to the control treatment. Water content of muscles during the transportation in 10g/ l salinity showed a significant (P≤ 0.05) increase in treatment T3 compared to the control treatment in the thyroxin hormone treatment in the 10 th day. However, in the cortisol hormone treatment, a significant (P≤ 0.05) decrease was recorded on the 10 th day in treatment T7 compared to other treatments. No effect was noticed of the thyroxin and cortisol hormones on the packed cell volume (PCV).

“…Salaei (2006) reported that plasma AST and ALT activity increased in Cyprinus carpio during catching process from ponds. Study of Sultan (2007) Reported an increase in plasma ALT and AST concentration with salinity increase in juveniles of Acanthopagrus latus which reared in (3, 23, 30) g/L salt solution. Lee et al (2016) suggested that Juveniles of Red-Spotted Grouper Epinephelus akaara exposed to sudden salinity drops from 34 psu to 18 or 10 psu still undergoes the primary adjustment phase ("alarming stage") before the fish reach a new homeostasis ("resistant stage").…”

The effects of Sudden and Gradual salinities stress on AST and ALT enzyme activity in Oreochromis aureus fingerlings were investigated in two separate experiments in this study. The fingerlings were suddenly transferred to five different set of salinities (5, 15, 25, 35, 45 psu) and gradually each one hour to seven set of salinities (5, 10, 15, 20, 25, 30, 35) psu in two replicate for each salinity for 72 hrs. Fish were killed after that and blood were taken from heart and putted in test tubes for serum separation and serum kept in freeze until doing measurements of AST and ALT enzymes. Results showed that all fishes were died in the salinity concentration 45 psu after 20 hrs of sudden transfer, while a 100% survival rate was recorded in other salinity concentrations. The salinity 45 psu was considered to be out of the O. aureus tolerance range. Findings showed a close correlation of AST and ALT concentrations with salinity increase in sudden and gradual transfer experiments as a result of the stress which occurred during fish acclimation to reach the homeostasis. The remarkable increase in serum ALT and AST of fish groups exposed to sudden transfer compared with gradual transfer groups reflect the better ability of these fishes to adapt in salinity changes of gradual transfer..
