With the objective of establishing tissue distribution and time variations of Se in the blue marlin Makaira nigricans and correlations of Se with the size of the fish, elemental concentrations were determined in the muscle and liver of 99 specimens from the Gulf of California collected between 2005 and 2012. Concentrations of Se were measured by hydride-generation atomic absorption spectrophotometry (HG-AAS). Considering all fish, average Se concentrations (µg g-1 wet weight) followed the decreasing order liver (1.552 ± 0.882) >muscle (0.804 ± 0.311). For the study period, Se concentrations in both tissues were more elevated in 2011 in comparison with the other years; nevertheless, the differences were not significant (p > 0.05). Positive correlations of Se levels with the size of fish were significant (p < 0.05); i.e. Se concentrations increased according to lower jaw fork length and weight of blue marlins. Although Se is homeostatically controlled, liver concentrations were higher than those in muscle.
