UNDERWATER CAMERA RESEARCH
I frequently work with Stereo Baited Remote Underwater Video surveys (sBRUVs), which is a noninvasive method to study various aspects of fish communties. I conducted a base-line fish survey on the Saba bank, which is a first step towards effective protection. He also developed robust, quantifiable objectives and reference points for conservation (and fisheries) in order to be able to evaluate the performance of management actions.
To study fish and shark populations around in Caribbean Netherlands, a fisheries independent sampling technique is required. Stereo Baited Remote Underwater Video (sBRUV) is such a technique. It is frequently used to study species richness, relative abundance and accurate length frequency of fish assemblages and shark populations, since most shark species are timid and therefore difficult to sample using traditional fish survey techniques such as diver based underwater visual survey (UVS). Its potential selectivity towards predator species that respond positively to the presence of bait and its ability to accurately perform length measurements, make sBRUV surveys a convenient technique to survey shark populations. Compared to conventional long-line surveys, baited video surveys are a standardized, non-invasive method to fish assemblages across broad spatial scales. This technique to study fish species richness and abundance in relation to various environmental factors is spreading rapidly in the last decade.
As a trainer of this technique to students and local conservationists in the Dutch Caribbean, I know the ins and outs of this technique. For more information on this research technique, please contact me via email or phone number mentioned on my contact page.
