Certification Process of Imported Pacific White Shrimp Litopenaeus vannamei （Boone, 1931） at Aquatic Quarantine Facility, India

The Aquatic Quarantine Facility （AQF） for Litopenaeus vannamei established under the Department of Animal Husbandry, Dairying and Fisheries, Ministry of Agriculture is located on the eastern coastal region of Chennai in Tamil Nadu, India. The facility is an approved quarantine premise for the SPF vannamei broodstock imported across India and is probably the only one of its kind to be established in Southeast Asia. The centre is managed and operated by Rajiv Gandhi Centre for Aquaculture （RGCA）, a technical extension of the Marine Products Export Development Authority （MPEDA）, Ministry of Commerce ＆ Industry, Government of India. The quarantine facility functions on the basis of strict biosecurity protocol and as per the guidelines stipulated in Standard Operating Procedures （SOP） framed by a team of experts. The facility ensures specific pathogen free status of the SPF L. vannamei broodstock imported to India, thus playing key role in restricting the entry of diseases to the Country. This article presents the SPF certification process of the imported L. vannamei carried out at the facility.

马达加斯加西海岸3种虾类CPUE时空分布及其与环境因子关系

为了解马达加斯加西海岸虾类的资源分布特征,利用中国水产有限公司马达加斯加代表处2012—2019年拖网渔业生产数据,基于GAM模型分析主要渔获种类(印度白虾Fenneropenaeus indicus、独角新对虾Metapenaeus monoceros和短沟对虾Penaeus semisulcatus)CPUE的时空分布及其与主要环境因子的关系。结果显示:印度白虾的CPUE从三月份开始呈逐月递减的趋势,而独角新对虾和短沟对虾CPUE呈先升后降的趋势;空间上,印度白虾和独角新对虾CPUE在经度上自东向西、纬度上自南向北呈现出逐渐上升的趋势,而短沟对虾CPUE在渔场南北端较高;水深对短沟对虾具有显著的影响(P<0.05);对于各环境因子,径流对独角新对虾和短沟对虾CPUE有显著的正相关关系(P<0.05),降水对印度白虾和短沟对虾CPUE有显著影响(P<0.05),海表面温度对独角新对虾CPUE有显著影响(P<0.05),独角新对虾和短沟对虾CPUE随海面高度距平的增加而显著降低(P<0.05),叶绿素a浓度对3种虾的CPUE均有显著影响(P<0.05)。结果表明,马达加斯加西海岸主捕虾类资源丰度具有明显的时空异质性,易受海洋环境、降水和径流等因素影响。研究结果可为开展该海域渔业资源丰度评估、规范渔业管理、养护渔业资源、保障渔业可持续发展提供科学依据。
