BRUVS (TM) - Fish and Benthic survey of Northern Great Barrier Reef Marine Park Seabed Project Cruise 5 2005-01-10 to 2005-02-11

The dataset comprises 13900 individuals from 168 species of fishes, sharks, rays and sea snakes observed at around Northern Great Barrier Reef Marine Park Seabed Project Cruise 5 using 174 baited remote underwater video stations (BRUVS(TM)). 1410 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.

本数据集涵盖北大堡礁海洋公园海底项目第5航次周边海域观测得到的13900个个体，隶属于168种鱼类、鲨鱼、鳐类及海蛇。本次观测共使用174台诱饵式远程水下视频站（BRUVS(TM)），从这些设备中共采集到1410张影像。

所有BRUVS(TM)项目中筛选出的约3500张优质影像已存入参考影像库。

所记录的数据涵盖以下内容：
- 视场内生境分类（包括地形、沉积物、底栖生物）
- 鱼类物种鉴定及CAAB编码
- 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为统计指标，即单次观测可见的最大个体数，或是可通过体型、性别等特征在不同时段区分的独立个体总数）
- 首次达到MaxN以及个体开始取食的耗时

澳大利亚海洋科学研究所（Australian Institute of Marine Science, 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。
