¹Values of each group were mean±standard error. Values in the same column not sharing common superscripts are significantly different among ploidy and season (P<0.05).
²All parameters of each group were measured in May, 2016 for spawning season and January, 2016 for non-spwaning season, respectively.
³Total saturated fatty acids.
⁴Total monounsaturated fatty acids.
⁵Total n-6 polyunsaturated fatty acids.
