NON-INVASIVE TAGS TO MONITOR MARINE MEGAFAUNA

OVERVIEW

With human activity on marine habitats on the rise, there is a need to deepen the knowledge on the ocean dynamics and quantify the impacts of the anthropogenic presence in these habitats. Implementation of Instrumented Animal-borne Tracking Devices, capable of In-Situ monitoring of deep-sea habitats and the behaviour of sea animals such as sharks and manta rays, enables not only for biologists and scientists to more accurately know their habits and infer on the impacts of the human activities, but as well helps legislators better adapt local and global policies for the exploitation of the ocean resources.

 

CEIIA developed, in partnership with IMAR (Azores), towed tagging devices which enable nonintrusive timed deployments on sea animals such as Manta Rays and Sharks, capable of recording and transmitting by satellite link a diversity of animal behaviour and habitat parameters (depth, global position, temperature, activity, velocity).

These tags are significantly smaller than the animals to be tagged and can integrate virtually any available type of sensor, transmitter and data logger to capture, register and transmit several parameters of interest regarding the animal and its habitat.
