  abstract = {{T}he use of a multi-ecological tracer approach provides valuable and complementary insights to investigate the complex biology and ecology of large pelagic fish. {B}rine immersion freezing is the most common preservation technique used onboard for large fish to be frozen whole until they are delivered for sale and processing. {W}e evaluated the effect of brine freezing on lipid and fatty acid composition, {C} and {N} stable isotope ratios, and organochlorine contaminant levels of yellowfin tuna ({T}hunnus albacares) and skipjack tuna ({K}atsuwonus pelamis). {F}resh tunas were stored in a saturated sodium chlorine brine immersion tank maintained at -20 {A} degrees {C} for 6 weeks, and ecological tracers were analysed on dorsal muscle samples collected before and after brine freezing. {N}o significant effect of the fish preservation technique was found except for delta {N}-15 whose signatures slightly increased after a 6-week period of brine immersion. {B}ecause {N} isotopic shift was close to the analytical precision and probably related to a higher risk of salt penetration in small tunas with abraded skin, we consider our results as conservative and conclude that ecological tracers can indeed be analysed on brine-freezing-preserved tunas.},
