The study was conducted to investigate the effect of adding palm pollen to the diet of common carp (Cyprinus carpio L.). One hundred and twenty fingerlings with an average weight of 18±2 g were used, distributed across four treatments: the first group as the control, the second involved adding palm pollen at a rate of 10 g/kg, the third at 20 g/kg, and the fourth at 30 g/kg, with three replicates per treatment, each containing 10 fingerlings. The fish were reared for 75 days in glass tanks equipped with oxygen pumps, and the fish were weighed every 15 days.

The study observed a significant increase in the total weight gain rates between the experimental treatments and the control group. The experimental treatments showed a significant improvement over the control group in daily weight gain, though no differences were noted among the different addition treatments. There was also a significant improvement in the specific growth rate (SGR) and relative growth rate (RGR) between the experimental treatments and the control group. The control group recorded the highest feed conversion ratio (FCR) compared to the addition treatments. The T4 treatment recorded the highest value and significantly outperformed the control in feed conversion efficiency (FCE). The addition treatments also significantly outperformed the control in protein efficiency ratio and body protein percentage, with no differences observed in protein productive value (PPV) and moisture and carbohydrate content in the fish body.

Based on the current study's findings, it is possible to conclude that using palm pollen powder as a feed addition increased fish growth parameter, feed conversion efficiency, and chemical composition.
