BRUVS (TM) - Fish and Benthic survey of Townsville Midshelf Reefs 2000-09-30 to 2000-10-05

The dataset comprises 1380 individuals from 128 species of fishes, sharks, rays and sea snakes observed at around Townsville Midshelf Reefs using 19 baited remote underwater video stations (BRUVS(TM)).

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.

本数据集涵盖在汤斯维尔中陆架礁（Townsville Midshelf Reefs）周边，通过19台诱饵式远程水下视频站（BRUVS(TM)）观测得到的128种鱼类、鲨鱼、鳐类及海蛇的1380个个体样本。
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。
记录的观测数据包含以下内容：
- 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编码
- 个体的到达时间
- 行为特征（共8个类别，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，或可在不同时段区分的独立个体，例如体型差异悬殊、雄性/雌性个体）
- 达到MaxN峰值及出现摄食行为前的耗时。
澳大利亚海洋科学研究所（AIMS）工作人员基于Microsoft Access开发了一款定制化数据分析界面，用于读取和分析BRUVS(TM)录像数据。
