项目摘要

Acceleration data loggers were attached to five adult Adeie penguins at Hukuro Cove, Luzow-Holm Bay in austral summer 1997/1998. The loggers recorded time series data of speed, depth, surging acceleration and swaying acceleration in flush memories inside. Resulting from time series analyses, the frequency of 2-to 3-Hz was found in the surging acceleration during descending in a straight line. The cycle seemed to correspond to wingbeat frequency of the Adeie penguin. The relation between the wingbeat frequency and diving depth was summarized that the frequency ranged from 1.5-Hz to 3.0-Hz when the penguins dive in the shallower water than 30-m and the frequency indicated over 2.5-Hz in the deeper water than 50-m depth. The acceleration data logger was the powerful tool to estimate kinematics parameters of free-ranging marine animals.Swimming behavior of free-range red sea breams were examined using data storage tags and a video recorder. The tags were able to measure activity parameters including both surging and swaying acceleration, swimming speed, and swimming depth. The adult red sea breams with the storage tag were released in an experimental fishpond and a fish pen. Five typical swimming patterns were found resulting from speed data. The types and their appearance frequencies were as follows; type 1 : dash and stop, 46.5%, type 2 : dash, moderate swim, and stop, 23.3%, type 3 : moderate swim, dash, and stop, 4.6%, type 4 : moderate swim and stop, 2.3%, and others, 23.3%.

1997/1998年夏季，在卢佐霍尔姆湾的Hukuro湾，将加速度数据记录仪安装在5只成年Adeie企鹅身上。记录仪将速度、深度、浪涌加速度和摇摆加速度的时间序列数据记录在内部的刷新存储器中。从时间序列分析的结果，2- 3-Hz的频率被发现在浪涌加速度在下降过程中的直线。该周期似乎与阿迪企鹅的翼振频率相对应。结果表明，企鹅在30 m以下的浅水区翼拍频率在1.5 ~ 3.0 Hz之间，在50 m以上的深水区翼拍频率在2.5 Hz以上。加速度数据记录仪是估算自由放养海洋动物运动学参数的有力工具，利用数据存储标签和视频记录仪对自由放养红鲷的游泳行为进行了研究。标签能够测量活动参数，包括涌动和摇摆加速度，游泳速度和游泳深度。将带有贮藏标签的成年真鲷放于实验池塘和鱼栏中。五个典型的游泳模式，发现由速度数据。其类型和出现频率如下：1型：冲刺和停止，46.5%，2型：冲刺、中等游动和停止，23.3%，3型：中等游动、冲刺和停止，4.6%，4型：中等游动和停止，2.3%，和其他，23.3%。
