BRUVS (TM) - Fish and Benthic survey of Southern Great Barrier Reef 2007-07-31 to 2007-08-12

The dataset comprises 4417 individuals from 193 species of fishes, sharks, rays and sea snakes observed at around Southern Great Barrier Reef using 33 baited remote underwater video stations (BRUVS(TM)). 973 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.

本数据集涵盖了大堡礁南部周边海域通过33台带饵远程水下视频站（BRUVS(TM)）观测得到的、隶属于193个物种的4417个个体，物种类型包括鱼类、鲨鱼、鳐类及海蛇。上述设备共采集到973张影像。

本次所有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（涵盖地形、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个类别，其中包含对诱饵的取食行为）
- 成熟度（成体或幼体）
- 相对丰度（以MaxN指标进行统计，MaxN指单次观测中可见的最大个体数，或可通过不同时段区分的独立个体，例如体型差异显著、性别不同的个体）
- MaxN出现与取食行为发生前的耗时时长

AIMS工作人员基于Microsoft Access开发了专用界面，用于BRUVS(TM)影像数据的读取与分析。
