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 reef fish populations. They can both be left free standing without the need of an operator.
A fish doorbell (Dutch: visdeurbel) is a system that allows fish to pass through a closed sluice gate through crowdsourced input when fish are present. The Utrecht Visdeurbel uses a livestreamed underwater camera that allows users to press a doorbell button to notify the lock operator that there are fish swimming in the gracht, and that the lock should be opened.

Monitoring, control and surveillance (MCS), in the context of fisheries, is defined by the Food and Agriculture Organization (FAO) of the United Nations as a broadening of traditional enforcing national rules over fishing, to the support of the broader problem of fisheries management.
The Seaview SVII Camera, used extensively throughout the Catlin Seaview Survey. The status of surveyed reefs is being documented using high-resolution, 360-degree panoramic vision. [2] These images are GPS-tagged with camera direction recorded, documenting precise locations. This method of documentation is intended to form a visual record of ...
Several different types of methods are used to attach the tag to an organism. In fish, tags are frequently embedded into the individual by cutting a small incision in the abdominal cavity of the fish (surgical implantation), or put down the gullet to embed the Acoustic Tag in the stomach (gastric implantation) [citation needed]. External ...
A resistive counter is associated with an in-river structure, an example constituting a Crump weir. [1] The resistivity of a fish is lower than that of water. So, as fish cross this barrier, they pass embedded electrodes, and the difference in resistivity disturbs the field established in the vicinity of the electrodes, altering inter-electrode resistance.
The history of wildlife tracking technology involves the evolution of technologies that have been used to monitor, track, and locate many different types of wildlife. Many individuals have an interest in tracking wildlife, including biologists, scientific researchers, and conservationists.
Tigress with radio collar in Tadoba Andhari National Park, India. GPS animal tracking is a process whereby biologists, scientific researchers, or conservation agencies can remotely observe relatively fine-scale movement or migratory patterns in a free-ranging wild animal using the Global Positioning System (GPS) and optional environmental sensors or automated data-retrieval technologies such ...
