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

The dataset comprises 1954 individuals from 90 species of fishes, sharks, rays and sea snakes observed at around Inshore Shoals : Halifax Bay using 25 baited remote underwater video stations (BRUVS(TM)). 293 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.

本数据集涵盖于哈利法克斯湾周边近岸浅滩，通过25台诱饵式远程水下视频站（BRUVS(TM)）观测得到的1954个个体，这些个体隶属于90个物种，涵盖鱼类、鲨鱼、鳐类与海蛇。
上述设备共采集得到293张影像。
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。
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）
- 鱼类的物种鉴定及CAAB编码（CAABCODES）
- 个体的抵达时间
- 行为模式（共8类，包括取食诱饵）
- 成熟状态（成体或幼体）
- 相对丰度（以MaxN即单次可见的最大个体数为统计基准，亦可根据不同时间可区分的独立个体，如体型差异悬殊、性别不同的个体进行计数）
- 达到MaxN阈值及个体开始取食所耗费的时间
澳大利亚海洋科学研究所（AIMS）的工作人员使用Microsoft Access开发了定制化分析界面，用于读取和分析BRUVS(TM)的录制影像数据。
