Abstract：A 28‐d feeding trial was conducted to access the effects of three diets including Manila clam (Ruditapes philippinarum) ,razor clam (Sinonovacula constrzcta) and crab (Hemigrapsus sanguineus) on food intake ,weight gain ,specific growth rate and food conversion efficiency in short arm octopus (Oc‐topus ocellatus) with initial body weight of (34 .82 ± 3 .79) g .The octopus were reared in a 500 mL plastic bottle disposed in a tank of 4 .1 m × 6 .6 m × 1 .4 m at a rate of one individual per bottle and randomly as‐signed to 3 groups ,each of which was fed one of the three diets with 6 replicates at water temperature of 23 .6—25 .8 ℃ and a salinity of 28—30 for 28 days .It was found that the short arm octopus had 100% of survival in all treatment groups .However ,there were significantly higher specific growth rate (1 .67% /d) and food conversion efficiency (33 .46% ) in the octopus fed crab H .Sanguineus than those in the octopus fed razor clam (1 .33% /d and 14 .01% ) and Manila clam (1 .31% /d and 19 .57% ) ,indicating that crab was the best diet for short arm octopus culture .
