BRUVS (TM) - Fish and Benthic survey of Heron Island 2014-06-23 to 2014-07-02

The dataset comprises 5097 individuals from 202 species of fishes, sharks, rays and sea snakes observed at around Heron Island using 56 baited remote underwater video stations (BRUVS(TM)). 311 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.

本数据集涵盖通过56台诱饵式远程水下视频站（BRUVS(TM)）在赫伦岛（Heron Island）周边观测得到的202种鱼类、鲨鱼、鳐类及海蛇的5097个个体，共从这些设备中拍摄得到311张图像。

从所有诱饵式远程水下视频站（BRUVS(TM)）项目中筛选出的约3500张优质图像被存入参考图库。

所记录的数据涵盖以下内容：
- 视场范围内的生境分类（包含地形、沉积物、底栖生物）
- 鱼类的物种标识及CAAB编码（CAABCODES）
- 个体的抵达时间
- 行为特征（共8类，包含以诱饵为食的行为）
- 成熟度判定（成体或幼体）
- 相对丰度统计（以MaxN指标为准，即单次观测到的最大可见个体数；或通过不同时刻观测到的可区分个体，如体型差异显著、性别不同的个体，进行独立计数）
- MaxN出现前的时长以及取食行为发生的时长

AIMS工作人员基于Microsoft Access开发了一款定制化界面，用于读取和分析诱饵式远程水下视频站（BRUVS(TM)）的录像数据。
