Skipjack Tuna

Sustainable alternatives: 
Pole/troll-caught Skipjack tuna is a sustainable seafood option.
Sustainability concerns: 
Overall, the management of tuna fisheries worldwide is considered inadequate. Some countries have instituted more rigorous measures, but better regulations are necessary for sustaining these fisheries.
Skipjack is found throughout many of the world’s oceans. Several harvest methods are used in Skipjack fisheries but Troll/Pole fisheries are the most sustainable. Skipjack caught in longline and FDA purse seine fisheries should be avoided due to their impact on sea turtle, seabird and marine mammal populations.
Life History and Population Status: 
Skipjack are fast growing, have short life spans and high reproductive output. These characteristics make them resilient to fishing pressure. The status of some skipjack populations is unknown, and while there is evidence of declines, none of the skipjack populations are considered overfished.
Management: 
Several international commissions conduct research on Tuna populations and provide recommendations to member countries on appropriate management measures. Management of the Western Central Pacific, US Eastern Pacific, US Atlantic and Hawaiian fisheries are considered to be effective. Observer coverage and enforcement is limited and stock assessments are lacking in many areas.
Impact on Other Species: 
Pole/troll gear-types are associated with low levels of bycatch. Specific estimates on the extent and nature of bycatch are not available but generally poll/troll harvests are a model for selective fishing.
Habitat and Ecosystem Impacts: 
Pole/troll gear has a low habitat impact. The removal of significant numbers of tuna, which are top predators, may have a serious impact on marine food-web dynamics.
