Skipjack tuna

Skipjack tuna is considered a single population for assessment purposes. There is some indication from tagging studies that it is a single population (IOTC 2015).

The structure of skipjack populations in the Indian Ocean is thought to consist of two different stocks, namely between the western waters of Sumatra and the southern waters of Java to Nusa Tenggara. The genetic diversity of skipjack populations in the Indian Ocean is relatively high so that the population status is likely not to be depressed by fishing activities (LRPT 2017). The ecological characteristics of skipjack tuna associated with FADs in the Indian Ocean are indicated by the main interactions with hook and line, and purse seine fishing gear, measuring between 8 - 67 cm FL, average 34 cm FL or aged around 1.7 years (LRPT 2016)


  • The population is currently estimated to be healthy with sustainable fishing mortality rates.
  • Indonesian does not adhere to national management strategies for tuna, skipjack and tuna-like species management, but refers to management mandatory through the IOTC. Indonesia already has a national tuna management plan that will serve as a guide for relevant institutions in the central and regional governments in their own annual activities related to tuna fisheries.
