A glimpse into the underwater world

Remote Underwater Video (RUV)

“Remote Underwater Video (RUV) is a promising tool for progressing the future of freshwater fisheries monitoring and management. While uses have previously been focused on marine systems there has been a rise in application for freshwaters. Given the potential for coordinated geographical research using RUVs it is essential that standardised methodologies are described and promoted. We therefore conducted a systematic literature review which returned 185 publications that discussed using RUVs in freshwater environments. ”

Underwater cameras offer a non-invasive way to observe fish populations. Here we show an example from the Nidda River near Bad Vilbel/Frankfurt am Main:

Bad Vilbel – Live insight into the underwater world of the Nidda river

The underwater camera (I AM HYDROCam) is located on the bottom of the Nidda River in the city center of Bad Vilbel (Hesse). It provides insights into the diversity of fish species and their behavior. This aims to open a window into largely unknown underwater worlds for many people.
