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、鳐鱼及海蛇，这些样本于汤斯维尔（Townsville）周边沙洲海域，通过20台诱饵式远程水下视频站（BRUVS(TM)）采集获得，该设备共拍摄得到299张图像。
所有BRUVS(TM)项目中精选出的约3500张优质图像已存入参考图像库。
本次记录的数据涵盖以下内容：
- 视野范围内生境的分类（包括地形、沉积物、底栖生物）
- 鱼类的物种鉴定信息及CAABCODES
- 个体的抵达时间
- 行为模式（共8类，包含以诱饵为食的行为）
- 成熟度（成体或幼体）
- 相对丰度（以最大个体数（MaxN）为统计指标，即同一时刻可见的最大个体数，或在不同时段可被区分的独立个体，例如体型差异显著的个体、雄性/雌性个体）
- 达到MaxN峰值以及开始取食所耗费的时长。
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)的录像资料。
