BRUVS (TM) - Fish and Benthic survey of Inshore Shoals : Halifax Bay 2007-03-29 to 2007-03-31

The dataset comprises 1007 individuals from 69 species of fishes, sharks, rays and sea snakes observed at around Inshore Shoals : Halifax Bay using 9 baited remote underwater video stations (BRUVS(TM)). 88 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69个物种的1007个个体样本，涵盖鱼类、鲨鱼、鳐类及海蛇，观测于哈利法克斯湾近岸浅滩海域，采用9台带饵远程水下视频站（BRUVS(TM)）完成数据采集，共获取88帧影像。

所有BRUVS(TM)项目中筛选出的约3500幅优质影像已存入参考影像库。

本次记录的数据涵盖以下内容：
- 视野范围内的生境分类（包括地形、沉积物、底栖生物）
- 鱼类物种鉴定信息及CAABCODES
- 个体抵达时间
- 个体行为（共8类，包含对饵料的摄食行为）
- 个体成熟度（成体或幼体）
- 相对丰度（以MaxN即单次观测到的最大可见个体数为统计标准，或通过不同观测时段中可明确区分的独立个体，如体型差异显著、性别不同的个体，进行统计）
- MaxN出现及摄食行为发生前的耗时时长

澳大利亚海洋科学研究所（Australian Institute of Marine Science，缩写AIMS）工作人员基于Microsoft Access开发了专用界面，用于读取和分析BRUVS(TM)采集的影像数据。
