Co-occurrence of genetically isolated groups of skipjack tuna (Katsuwonus pelamis) within the Indian Ocean

In order to resolve the population connectivity of skipjack (Katsuwonus pelamis) within the Indian Ocean, we analyzed thousands of genome-wide markers of individuals from a broad geographic area of the Indian Ocean, as well as from one location in the Atlantic Ocean. Our results support a complex stock structure with multiple genetically isolated populations co-occurring in most locations, and claim for additional analyses to further understand the population structure of skipjack tuna within the Indian Ocean.
