چکیده
The effect of fishmeal (FM) replacement with Spirulina (Arthrospira platensis) meal (SPM) was investigated in Asian seabass (Lates calcarifer) diet. Dietary FM was replaced with SPM at ۵ (SP۵%) and ۱۰% (SP۱۰%) and a diet without SPM served as the control group. One hundred and thirty five L. calcarifer juveniles (۴۵.۰ ± ۰.۲ g) were randomly distributed into nine ۳۰۰-L circular polyethylene tanks (۱۵ fish/tank). SP۱۰% group had the highest final weight that was associated with better feed conversion ratio value. A higher gut amylase activity was observed in SPM-treated groups than the control group. SP۵% group had a higher gut trypsin activity than other treatments. The liver superoxide dismutase activity in SP۵% was higher than the other groups. The liver reduced glutathione level increased with increasing SPM level in the diets. The plasma lysozyme activity in SP۱۰% group was higher than other groups. The plasma cholesterol and alkaline phosphatase contents decreased in the fish fed with SP۵%. The plasma aspartate aminotransferase decreased in the fish fed with SPM-supplemented diets. Based on the above-mentioned findings, dietary FM replacement with SPM at ۱۰% is recommended for growth and improving health status in L. calcarifer juveniles.کلیدواژه ها
