| 摘 要： | 为研究不同饵料模式及投喂方式对中间球海胆（Strongylocentrotus intermedius）生长及性腺发育的影响。采用不同饵料模式（M1：海带、M2：海带＋贻贝、M3：南瓜、M4：胡萝卜）和不同投喂方式（RM1：饲喂南瓜75天后饲喂海带75天;RM2：饲喂胡萝卜75天后饲喂海带75天）两种实验方案,以M1模式为对照组,对中间球海胆生长指标及性腺性状进行测量并分析,实验周期150天。结果显示：不同饵料模式下,M1（57.84±3.25）mm、（72.58±11.07）g和M2（56.60±2.66）mm、（69.62±8.94）g模式的海胆壳径及活体重差异不显著（P〉0.05）,二者极显著（P〈0.01）高于M3（53.10±2.28）mm、（57.31±8.18）g和M4（50.12±1.70）mm、（50.45±4.27）g模式;M2模式下雌、雄海胆的性腺指数（31.22±3.31）%、（30.92±2.76）%均极显著（P〈0.01）高于其他3种饵料模式;M2模式下雄海胆的亮橙黄色差ΔE1和亮黄色差ΔE2均显著（P〈0.05）优于对照组（M1模式）,雌海胆ΔE1、ΔE2则与对照组差异不显著（P〉0.05）,表明：添加动物性蛋白（M2模式）对促进海胆性腺指数、性腺品质的提升效果显著（P〈0.05）,但对其生长影响不显著（P〉0.05）。不同投喂方式下,RM1（55.46±2.19）mm模式的海胆壳径显著低于对照组（57.84±3.25）mm（P〈0.05）,活体重（68.63±7.39）g与对照组（72.58±11.07）g差异不显著（P〉0.05）,RM1和RM2模式下海胆在75-150天的壳径增长率（12.55±0.22）%、（12.68±1.78）%和增重率（29.60±4.20）%、（30.53±2.09）%均显著高于对照组（9.79±0.97）%、（19.86±4.86）%（P〈0.05）;海胆性腺指数在不同性别不同模式间均差异不显著（P〉0.05）;RM1和RM2模式下海胆的亮橙黄色差ΔE1和亮黄色差ΔE2均差异不显著（P〉0.05）,二者显著（P〈0.05）优于对照组且在性别间表现一致,表明：饲喂南瓜75天后饲喂海带75天的投喂方式不会显著（P〉0.05）影响海胆

| Abstract: | In order to study the effects of different feeding models and feeding ways on growth, gonaddevelopment of S.intermedius, the growth targets and gonad traits of S.intermedius were measured and analyzedin the experiment under different feeding models（M1： kelp, M2： kelp＋mussel, M3： pumpkin, M4： carrot） anddifferent feeding ways（RM1： feed kelp after feeding pumpkin for 75 days, RM2： feed kelp after feeding carrot for75 days）. The results showed that on conditions of the different feeding models, there＇s no significant differencebetween M1（57.84±3.25） mm,（72.58±11.07） g and M2（56.60±2.66） mm,（69.62±8.94） g on test diameter andweight of sea urchin（P0.05）, both of them were significantly different with M3（53.10±2.28） mm,（57.31±8.18） gand M4（50.12±1.70） mm,（50.45±4.27） g models（P0.01）; the GI of M2（♀：31.22±3.31）%,（♂：30.92±2.76）%model was significantly higher than the other three models（P0.01）; the light orange-yellow ΔE1 and light-yellow ΔE2of female S.intermedius under M2 model were significantly better（P0.05） than control group（M1model）, which was not significantly different with control group in male S.intermedius（P0.05）. The resultssuggested that： the bait added with animal protein has obvious promoting effects on the gonad index and thequality of the gonad（P0.05）. On conditions of the different feeding ways, the test diameter of control group（57.84 ± 3.25）mm was significantly higher than RM1（55.46 ± 2.19） mm model, and there＇s no significantdifference（P0.05） between RM1（68.63±7.39） g model and control group（72.58±11.07）g on weight, the growthrate of diameter（12.55±0.22）%,（12.68±1.78）% and weight（29.60±4.20）%,（30.53±2.09）% under RM1 andRM2 models were significantly higher（P0.05）than control group（9.79±0.97）%,（19.86±4.86）% during 75 daysto 150 day. There＇s no significant difference（P0.05）with the GI in different gender and feeding ways. Ther |
