BRUVS (TM) - Fish and Benthic survey of Shoals: Townsville 2007-11-12 to 2007-11-19

The dataset comprises 1539 individuals from 73 species of fishes, sharks, rays and sea snakes observed at around Shoals: Townsville using 20 baited remote underwater video stations (BRUVS(TM)). 299 images were captured from these cameras.

Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library.

Data recorded concern:
- classification of the habitat in the field of view (topography, sediments, benthos)
- the identity of fish and CAABCODES
- their time of arrival
- their behaviour (8 categories, including feeding on the bait)
- their maturity (adult or juvenile)
- their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female)
- the time elapsed before MaxN and feeding occurs.

A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes.

本数据集包含1539个观测个体，涵盖73种鱼类、鲨鱼、鳐类及海蛇，这些样本于汤斯维尔附近的浅滩区域，通过20台带饵远程水下视频站（BRUVS(TM)）采集获得，本次观测共从这些设备中获取299张图像。

所有BRUVS(TM)项目中筛选出的约3500张优质图像已存入参考数据库。

本次记录的数据集内容包括：
- 视场范围内的生境分类（涵盖地形、沉积物、底栖生物）
- 鱼类物种鉴定及CAAB编码（CAABCODES）
- 个体到达时间
- 行为特征（共8类，包含以诱饵为食的行为）
- 个体成熟度（成年或幼体）
- 相对丰度（采用MaxN指标，即单次可见的最大个体数，或不同时间可区分的独立个体数，例如体型差异悬殊、性别不同的个体）
- 达到MaxN峰值以及出现摄食行为前的耗时

澳大利亚海洋科学研究所（AIMS）工作人员基于Microsoft Access开发了定制化分析界面，用于读取和分析BRUVS(TM)录制的视频资料。
