Accurate identification of humpback whale diet is important for predicting the spatiotemporal overlap between whales and fisheries. However, difficulty surveying whales from large ships and limited sampling methods for baleen whale prey have precluded reliable data collection on baleen whale feeding habits in BC waters. An ability to collect high resolution prey data from a small vessel is essential for these studies. Subsurface prey near feeding humpback whales can then be surveyed in conjunction with traditional whale surface observations. ASL Environmental Sciences (ASL) offers a possible solution through modification of the ASL Acoustic Zooplankton and Fish Profiler (AZFP). Designed for stationary mooring on the seafloor, we will use the AZFP in a vessel-mounted, downward-looking orientation from the sea surface. This requires modifying the AZFP's external hardware and developing custom software. The objectives of this project are to (i) modify the AZFP for efficient use on small boats and (ii) evaluate the performance of the AZFP regarding its utility for collecting high-resolution prey data near feeding baleen whales.

准确识别座头鲸的饮食对于预测鲸鱼和渔业之间的时空重叠非常重要。然而，从大型船只上测量鲸鱼的困难和对须鲸猎物的有限采样方法排除了在BC沃茨收集须鲸食性的可靠数据。从小型船只上收集高分辨率猎物数据的能力对这些研究至关重要。然后，可以结合传统的鲸鱼表面观察来调查喂养座头鲸附近的水下猎物。 ASL环境科学（ASL）通过修改ASL声学提供了一种可能的解决方案。 浮游动物和鱼类剖面仪（AZFP）。AZFP设计用于海底固定式系泊，我们将在船舶上使用，从海面向下看。这需要修改AZFP的外部硬件和开发定制软件。 该项目的目标是（i）修改AZFP，以便在小型船只上有效使用，以及（ii）评估 AZFP关于其在摄食鲸须附近收集高分辨率猎物数据的实用性的性能 鲸鱼
