The turbid, low-light waters characteristic of aquaculture ponds have made it difficult or impossible for previous video cameras to provide clear imagery of the ponds' benthic habitat. We developed a highly sensitive, underwater video system (UVS) for this particular application and tested it in shrimp ponds having turbidities typical of those in southern Taiwan. The system's high-quality video stream and images, together with its camera capacity (up to nine cameras), permit in situ observations of shrimp feeding behavior, shrimp size and internal anatomy, and organic matter residues on pond sediments. The UVS can operate continuously and be focused remotely, a convenience to shrimp farmers. The observations possible with the UVS provide aquaculturists with information critical to provision of feed with minimal waste; determining whether the accumulation of organic-matter residues dictates exchange of pond water; and management decisions concerning shrimp health.
水产养殖池塘具有浑浊、光线较暗的水体特征，这使得以往的摄像机很难或无法提供池塘底栖生物栖息地的清晰图像。我们针对这一特殊应用开发了一种高灵敏度的水下视频系统（UVS），并在台湾南部典型浑浊度的对虾池塘中进行了测试。该系统高质量的视频流和图像，以及其摄像能力（最多九个摄像头），能够对虾的摄食行为、虾的大小和内部解剖结构，以及池塘沉积物上的有机物质残留进行原位观察。UVS可以连续运行并可远程聚焦，这为虾农提供了便利。通过UVS进行的观察为水产养殖者提供了关键信息，有助于以最少的浪费提供饲料；确定有机物质残留的积累是否决定池塘水的交换；以及有关虾健康的管理决策。
