COLSHARK program: first satellite tagging of thresher shark (Alopias pelagicus) in Eastern Tropical Pacific Ocean

Armelle Jung’s presentation at the European User Conference on Argos Wildlife (EUCAW) will focus on the pelagic thresher shark (Alopias pelagicus). It is one of the largest and most abundant open ocean predators in the Eastern Tropical Pacific (ETP), and one of the most exploited shark in the sub-region. A. pelagicus has been classified as Vulnerable on the IUCN Red List since 2004.

Since 1994, there have been a progressive reduction of the landed volumes and the average size of captures. This information is a serious concern; given the number of people who depend on fishing in this area and the ecological repercussions linked with top elasmobranchs decrease.

Using Argos to learn about the biology and ecology of the pelagic thresher shark

Nonetheless, little is known about the biology and ecology of this species and the pelagic thresher shark is consequently recognized as the highest priority species for management in the Colombian (Shark NPOA) which various time series research activities for the study of its biology and ecology. Short-term research activities include the study of the migrations and movement patterns along the Pacific Coast while population genetics are identified as long-term activities both selected
