BRUVS (TM) - Fish and Benthic survey of Shoals : Southern Great Barrier Reef 2007-02-05 to 2007-02-20

The dataset comprises 8953 individuals from 192 species of fishes, sharks, rays and sea snakes observed at around Shoals : Southern Great Barrier Reef using 43 baited remote underwater video stations (BRUVS(TM)). 1285 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.

本数据集涵盖192个物种的8953个个体，包括鱼类、鲨鱼、鳐类及海蛇，观测区域为南大堡礁（Southern Great Barrier Reef）浅滩（Shoals）周边，采用43台诱饵式远程水下视频站（BRUVS(TM)）完成观测，共采集得到1285张图像。

所有诱饵式远程水下视频站项目筛选出的约3500张优质图像，已存入参考图像库。

所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）
- 鱼类物种鉴定及CAAB编码（CAABCODES）
- 个体的到达时间
- 个体行为（共8个类别，包括对诱饵的取食行为）
- 个体成熟度（成体或幼体）
- 相对丰度（以MaxN（最大可见个体数）为统计指标，或采用不同时段可区分的独立个体数作为统计依据，例如体型差异悬殊、雌雄有别的个体）
- 达到MaxN以及开始取食前的耗时

澳大利亚海洋科学研究所（AIMS）的工作人员基于Microsoft Access开发了定制化界面，用于读取和分析BRUVS(TM)采集的视频数据。
