Through analysis of the biotelemetry data, MigraMar has shown repeatedly that the Marine Corridor is ecologically connected.

Among the migratory species that inhabit these waters, there are a number of intense commercial interest, such as tuna, which are of great importance as food and to the economy. However, we can also find other non-commercial species. MigraMar studies focus on over 20 species, including:

All these species usually carry out migrations, either for feeding, breeding or for their different life stage needs. Unfortunately they are not free of threats, even though many of them are protected under international agreements and treaties.

As a research strategy we use aquatic biotelemetry in order to study the migratory patterns of pelagic species, this information is used subsequently to create key habitat maps and migration routes, and to generate hypotheses regarding factors still unknown, related to the biology and ecology of each species.

MigraMar uses two types of technology:

About tagging

During its first decade of work, MigraMar has successfully tagged over a thousand individuals of different migratory species in the Eastern Pacific with both acoustic and satellite tags.

Furthermore, around 100 receivers of acoustic signals have been installed, thus creating a network that stretches the length and breadth of the Marine Corridor, which will facilitate the continued study of these species.
