Tagging History

2000 - 2004

Hawai’i Division of Aquatic Resources (DAR) Ulua Tagging Project

Hawaiʻi’s original volunteer fish tagging project. Initially created in 1997 as a partnership between the state and members of the Hilo Casting Club, this project later expanded to include volunteer taggers statewide and collected valuable scientific information on Hawaiʻi’s ulua and papio (trevally) populations.

2007 - 2015

PIFG Deep 7 Bottomfish Tagging Project

Working with expert bottom fishermen throughout the Pacific, PIFG has deployed over 16,000 tags in members of the "Deep 7” (some of Hawaiʻi’s most prized bottomfish) and contributed to significant advancements in the scientific understanding of those species.

2012 - 2013

PIFG ʻŌʻio Tagging Project

Working with lifelong commercial net fishermen, PIFG applied traditional Hawaiian fishing knowledge to a high volume mark-recapture study, tagging and releasing 3,000 ʻōʻio (bonefish) off the south shore of Oʻahu.

PIFG ʻAhi Tagging Project

In partnership with Dr. Molly Lutcavage and local longline captains, PIFG deployed both satellite and conventional dart tags in yellowfin and bigeye tuna (ʻahi) of different sizes to improve scientific understanding of their movement patterns.

2016 - 2019

PIFG Striped Marlin Tagging Project

In partnership with Dr. Molly Lutcavage and Dr. Chi Hin Lam, PIFG deployed satellite and conventional dart tags in juvenile and adult striped marlin (nairagi) to better understand their migration patterns, seasonality, and oceanographic associations in Hawai’i and across the Pacific.

2016 - Today!

PIFG Tag It: Nearshore Gamefish Tagging Program

Tag It is a combined tagging initiative that focuses on the main target species of Hawaiʻi’s nearshore recreational fisheries: Papio/ulua (trevally) species, kahala (amberjack & almaco jack), ʻōʻio (bonefish), moi (threadfin) and kaku (barracuda).

The program provides valuable data on Hawaiʻi’s gamefish populations for applied scientific studies, such as this one on predator species in Heʻeia fishpond (2017).

Today, we continue to encourage our fishing community to support sustainable fisheries and be active in citizen science by getting involved with our tagging program!
