Baited remote underwater video
Baited remote underwater video (BRUV) is a system used in
Baited cameras are highly effective at attracting scavengers and subsequent predators,[1] and are a non-invasive method of generating relative abundance indices for a number of marine species.[2]
As a non-extractive technique, it offers a low environmental impact way of understanding changes in fish numbers and diversity over time. BRUV surveys were developed in Australia, and are now used around the world for a variety of projects. This is a low budget monitoring system that is less reliant on the availability of skilled labour and may make sustainable monitoring more practical, over the long term.[3]
There are two main types of remote video technique which have been used to record
The colour of the lighting used for video may influence behaviour of the target species.[5]
