Effect of salinity stress on body composition of silver carp fingerlings (Hypophthalmichthys molitrix)

This study was carried out in Shahid Maleki Warm Water Fish Culture Centre in Ahwas to investigate the effects of salinity levels (1>, 3, 6, 9 and 12 ppt) on moisture, crude protein and crude lipid in body composition of silver carp fingerlings (Hypophthalmichthys molitrix) (weight: 13.55±0.726 g and length: 11.04±0.093 cm) during 21 days. At 12 ppt all fishes died prior to 14 days. Findings of body composition at the end of the study revealed no significant variation in protein and lipid (p>0.05) but salinity produced a significant body dehydration (p<0.05).
