| 摘要: |
| 为优化马氏珠母贝苗种运输技术,提高运输效率,以马氏珠母贝(Pinctada fucata)稚贝为研究对象,分别以有水和无水两种运输方式汽运8 h条件下开展实验,比较分析其在运输前后、运输后恢复阶段的生长、消化和抗氧化性能。结果显示:有水运输后存活率达98%,无水运输97%;在恢复期第14 d,有水运输和无水运输存活率分别达97%、96%;有水运输皮质醇含量由(2 607.61±15.27)μg/L显著降低至(1 412.98±5.09)μg/L,无水运输后显著降低至(2 287.36±10.18)μg/L;在恢复期第7 d和14 d皮质醇含量均呈逐渐上升趋势;有水和无水运输后和恢复期淀粉酶活性不断上升,且有水运输酶活性高于无水运输(P<0.05),最高值为(1.43±0.05) U/mg prot;有水和无水运输后及恢复期超氧化物歧化酶酶活性在不断下降,最低下降至(16.00±0.14) U/mg prot,有水运输超氧化物歧化酶活性均高于无水运输(P<0.05);有水运输碱性磷酸酶、谷草转氨酶和谷丙转氨酶活性均上升,无水运输均下降;在恢复阶段,碱性磷酸酶活性在不断下降,谷草转氨酶和谷丙转氨酶活性在不断上升。有水和无水运输会对马氏珠母贝稚贝产生不同的影响,有水运输方式相对无水运输方式可使马氏珠母贝稚贝在后期阶段具有更好的存活效果和生长状态。 |

| Abstract: |
| To optimize the transportation technology and efficiency of Pinctada fucata juveniles, the survival, growth, digestion, and antioxidant capacity were studied after 8-h automobile transportation with or without water and in 7~14-day recovery. Results show that after the transportation with and without water, the survival rate was 98% and 97%, and remained high after 14-day recovery at 97% and 96%, respectively. After transportation, the cortisol decreased significantly from (2 607.61±15.27) to (1 412.98±5.09)μg/L in with-water case, while decreased to (2 287.36±10.18)μg/L in without-water case. In the recovery stage, the cortisol trended to increase gradually; and the amylase activity was increased continuously, being much higher with water [max. (1.43±0.05) U/mg prot]] than that without water. The superoxide dismutase (SOD) activity decreased continuously [min. (16.00±0.14) U/mg prot], of which with-water case was higher than without water (P<0.05). The activity of alkaline phosphatase (AKP), glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) were increased in with-water case, while decreased in without-water case. In the recovering stage after transportation, AKP activity was decreased continuously, while GPT and GOT increased. Therefore, effects of transportation mode (with/without water) on growth performance of P. fucata juveniles were different. In general, the survival and growth of P. fucata juvenile by with-water transportation were better than those with no water. |
