The best result was observed in the experiment conducted at 35ppt salinity using N. oculata as the main food (378 ind/ml).]]>

0.05) in the control incubator. This indicates that eggs have absorbed these elements from incubation water and then showed increasing trend for Zn and Fe elements concentration in dry weight egg extract during incubation stages but increasing trend in Mn and Cu elements went on until the third stage. The results indicate that threshold concentrations for Mn and Cu in egg cause egg resistance against more absorption of these elements. Also, the results showed that at all sampling stages, concentration of the studied elements was lower than EPA standards for animal textures.]]>

Liver enzymes including AST, ALT and LDH at the level of 0.35% and ALP at the level of 0.25% were significantly lower than control treatment (P<0.05). Our results also indicated that dietary nucleotide can have positive effects on growth performance and would decrease liver demolition.]]>
