Video analysis of fish behaviour in the laboratory and field

我们要求为数字视频设备提供资金，由我们的研究小组共享。布朗实验室的重点是化学传感线索在评估和避免各种捕食性鱼类(包括溪流栖息的鲑鱼)的捕食威胁中所起的作用，以及人为污染物对检测这些至关重要的线索的影响。格兰特博士的研究项目专注于各种鱼类物种相对使用干扰和剥削性竞争的生态原因，以及这种竞争性相互作用在自然条件下调节种群规模中所起的作用。但两个研究小组都严重依赖视频记录来收集详细的行为数据。目前，我们仅限于一个SVHS和一个数码摄像机。我们的设备需求包括数码摄像机、迷你DV到DVD录制平台和用于视频分析的计算机。这些录制平台将允许我们将实验室和实地研究的原始视频片段存档为稳定的DVD格式，从而消除因磁带丢失或损坏而导致数据丢失的风险。*增加两台Apple iMac电脑将消除使用视频摄像头进行视频播放的需要，使它们可用于数据收集并减少整体磨损。我们选择这些产品作为成本最低的平台，满足我们当前和未来的需求。所要求的视频分析系统将大大增强我们的研究小组收集和分析实验室和现场实验中的行为数据的能力。此外，通用视频平台的提供将促进我们实验室之间的合作项目。

We are requesting funds for digital video equipment, to be shared between our research groups.  The Brown laboratory focuses on the role chemosensory cues play in the assessment and avoidance of predation threats by a variety of prey fishes, including stream dwelling salmonids, and the effects of anthropogenic pollutants on the detection of these critically important cues. Dr. Grant's research program focuses on the ecological causes of the relative use of interference versus exploitative competition in a variety of fish species, and the role such competitive interactions play in the regulation of population size under natural conditions.  Both research groups rely heavily on the use of video recordings to collect detailed behavioural data.  Currently, we are limited to a single SVHS and a single digital video camera. Our equipment request consists of digital video cameras, mini DV-to-DVD recording decks and computers for video analysis.  The recording decks will allow us to archive raw video footage from lab and field studies into a stable DVD format, thus eliminating the risk of data loss due to tape loss or damage.  The addition of two Apple iMac computers will eliminate the need to use video cameras for video playback, making them available for data collection and reducing overall wear. We have selected these items as the lowest cost platform that addresses our current and future needs. The requested video analysis system will represent a significant enhancement in the ability of our research groups to collect and analyze behavioural data in both laboratory and field experiments. In addition, the availability of a common video platform will facilitate collaborative projects between our laboratories.
