Abstract

For this research, 240 pieces of sea carp fry (with an average weight of 5±1g) were transported in 4 different salinity treatments of 0, 1, 3 and 6 g/l in three replicates (in plastic bags) for one hour. In order to check the blood parameters of the baby fish at the end of the experiment, blood was taken from the samples by cutting the tail stem. According to the results of measuring some biochemical parameters of blood serum, the amount of total protein did not show a significant difference between different treatments (P>0.05), but the amount of glucose and cortisol showed a significant decrease in saline treatments compared to the control (P<0.05). The results of measuring liver enzymes in the amount of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase showed no significant difference between different treatments (P>0.05). The results of measuring some blood hematology factors also indicated no significant difference in the number of red and white blood cells, hematocrit percentage and hemoglobin level in the treatments. (P>0.05). In general, it can be said that Fewer stress indicators were observed in the transported fish treated with 3 grams of salt per liter.
