BRUVS (TM) - Fish and Benthic survey of Shoals: Townsville 2007-11-12 to 2007-11-19

The dataset comprises 2139 individuals from 68 species of fishes, sharks, rays and sea snakes observed at around Shoals: Townsville using 10 baited remote underwater video stations (BRUVS(TM)). 172 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.

本数据集包含在汤斯维尔浅滩区域利用10台诱饵式远程水下视频站（BRUVS(TM)）观测得到的2139个个体，涵盖68种鱼类、鲨鱼、鳐类及海蛇。本次观测共从这些设备中采集172张影像。

所有诱饵式远程水下视频站项目中精选出的约3500张优质影像，已存入参考数据库。

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）
- 鱼类物种鉴定及CAABCODES
- 个体抵达时间
- 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为统计依据，例如体型差异悬殊、性别不同的个体）
- 达到MaxN及个体开始取食前的耗时

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