Abstract :
AbstractIn this research, serum ions such as Calcium (Ca2+), Sodium (Na+), Potassium (K+), Phosphorus (P), and Magnesium (Mg2+) and metabolic indices (cholesterol, total protein, albumin and osmolarity) levels of 34 Acipenser persicus captured by trawling method in Guilan Province were studied in three weight groups including group 1 (<100g), group 2 (100 – 500 g) and group 3 (>500g) during 2009 – 2012. Results showed that Mg2+, Ca2+, K+ and P showed significant difference between different groups (P<0.05), but Na+ showed no significant difference between them (P>0.05). In group 1, Ca2+and Mg2+ ions were more than the other groups. There was no significant difference in osmolarity, cholesterol and albumin between different groups, but there was significant difference in total protein level in group 1 with group 2 (P<0.05). Cholesterol and total protein levels were maximum at group 3, but albumin level was minimum at group 3. In group 1, fish were more sensitive than others to environmental conditions. Therefore, respecting to the relationship between ions and metabolic factors in growth, reproduction and osmoregulation in Acipenser persicus, results of this study can be used for investigation of health, diagnosis of pathogens and catch management of this species in the Caspian Sea.
