BRUVS (TM) - Fish and Benthic survey of Southern Great Barrier Reef 2007-07-31 to 2007-08-12

The dataset comprises 4417 individuals from 193 species of fishes, sharks, rays and sea snakes observed at around Southern Great Barrier Reef using 33 baited remote underwater video stations (BRUVS(TM)). 973 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.

本数据集包含在南大堡礁周边海域通过33台诱饵式远程水下视频站（BRUVS(TM)）观测得到的193种鱼类、鲨鱼、鳐鱼与海蛇的4417个个体样本，共由这些设备拍摄获取973张图像。

来自所有BRUVS(TM)项目的约3500张优质图像已存入参考库中。

本次记录的数据涵盖以下内容：
- 视场范围内的生境分类（包括地形、沉积物、底栖生物）
- 鱼类物种鉴定信息及CAAB编码
- 个体到达拍摄区域的时间
- 个体行为（共8个类别，包括以诱饵为食的行为）
- 个体成熟度（成年或幼年个体）
- 相对丰度指标（以MaxN表示，即单次观测中可见的最大个体数，或可通过不同时段区分的独立个体，例如体型悬殊、性别不同的个体）
- 首次达到MaxN以及发生取食行为前的耗时时长

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