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.

本数据集包含在哈利法克斯湾近岸浅滩附近通过9台诱饵式远程水下视频站（BRUVS™）观测得到的1007个个体，隶属于69个物种，涵盖鱼类、鲨鱼、鳐类与海蛇。
该批设备共采集到88帧影像。所有BRUVS™项目中精选的约3500帧优质影像被存入参考影像库。
所记录的数据涵盖以下类别：
1. 视场内生境的分类（包括地形、沉积物、底栖生物）；
2. 鱼类的物种识别及CAABCODES；
3. 个体的抵达时间；
4. 行为特征（共8类，包含对诱饵的摄食行为）；
5. 成熟状态（成体或幼体）；
6. 相对丰度（以MaxN，即单次观测到的最大个体数，或不同时段可区分的独立个体数（如体型差异显著的大小个体、雌雄个体）为统计依据）；
7. 达到MaxN及出现摄食行为前的时长。
澳大利亚海洋科学研究所（AIMS）的工作人员基于Microsoft Access开发了专用界面，用于BRUVS™录像的读取与分析。
