| 摘 要： | 在盐度28~30、水温23.6~25.8℃下,将54只初始体质量(34.82±3.79)g的健康短蛸放入500mL矿泉水瓶中,瓶体周身均匀钻直径5mm小孔约80个,每瓶1只,悬挂在4.1m×6.6m×1.4m养殖池中,投喂菲律宾蛤仔、缢蛏和肉球近方蟹3种饵料,每种饵料3个平行组,比较分析3种饵料对短蛸生长的影响。28d的饲养表明,3个饵料组的成活率均为100%,但投喂肉球近方蟹的短蛸特定生长率(1.67%/d)和饵料转化效率(33.46%)显著高于投喂缢蛏(1.33%/d,14.01%)和菲律宾蛤仔(1.31%/d,19.57%)的短蛸(P0.05)。试验结果表明,蟹类是短蛸养成阶段较理想的饵料。

Effects of Different Diets on Growth of Shot Arm Octopus Octopus ocellatus |
| |
| 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 . |
