Abstract: Commonly known Arabian yellow fin sea bream (Acanthopagrus arabicus) were selected for trials.Specimens were procured from the Sonari channel (24°53'13.81"N66°41'44.57"E.),shifted to laboratory, and placed into 162 liter capacity glass aquaria, where they were subsequently acclimated for 60 days.Fish were fed in ration of 3% live body weight of feed.Two treatments were placed (T1 & T2).Individuals placed under T1 treated with soybean meal (SM) and individuals under T2 treated with fish meal (FM).Physicochemical parameters were recorded.pH, salinity (ppt), and temperature (27°C) were measured on daily basis, while ammonia, dissolved oxygen (DO), and nitrite nitrogen were evaluated on weekly basis.Length (cm) and weight (g) of under treatment individuals recorded thrice in a month.The mean final weight for treatments (T1 and T2) endured 8.11±0.12 and 8.12±0.13g, respectively, while the mean achieved length was 10.24±0.11cm and 10.31±0.12cm.Results showed the minimal weight increase in T2 alongside the slight difference in specific growth rate.Meanwhile, based on weight increase, feed conversion ratio, and specific growth rate there was a minute difference in growth between the two meals (SM & FM), whereas biochemical analysis revealed that SM impacted the individuals as greater levels of crude fat (51.23±0.947),crude protein (62 ±2.8284) found.Hence, soybean meal (SM), which is affordable, proved that it could be a possible diet that can replace traditional fish meal (FM) for cultivation of A. arabicus in aquaculture facilities to achieve marketable size.
