BRUVS (TM) - Fish and Benthic survey of Inshore Shoals : Townsville 2006-10-28 to 2006-10-30

The dataset comprises 1260 individuals from 87 species of fishes, sharks, rays and sea snakes observed at around Inshore Shoals : Townsville using 21 baited remote underwater video stations (BRUVS(TM)). 338 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.

本数据集涵盖在汤斯维尔附近近岸浅滩，通过21台诱饵式远程水下视频站（BRUVS(TM)）观测得到的1260个观测个体，分属87种鱼类、鲨鱼、鳐类及海蛇；上述设备共采集得到338帧图像。

所有BRUVS(TM)项目中筛选出的约3500幅优质图像已存入参考图库。

所记录的数据包括以下内容：
- 视场内生境分类（涵盖地形、沉积物、底栖生物）
- 鱼类种类鉴定及CAABCODES编码
- 个体抵达时间
- 行为模式（共8类，包含取食诱饵行为）
- 成熟度（成体或幼体）
- 相对丰度（以MaxN表示：单次观测可见的最大个体数，或可通过体型、性别等特征区分的不同时段出现的独立个体，例如体型悬殊的个体、雄性/雌性个体）
- 达到MaxN及发生取食行为的耗时

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)录制的影像数据。
