DHA also plays an important role in adaptive processes (temperature, salinity, and oxygen adaptations), as well as in the motoric and social behavior of fish (Shuhnan and Love, 1999). There is a correlation between the fish DHA content and mobility of salt and freshwater fish (Reinhardt and van Vleet, 1986 Shulman and Love, 1999, and references therein). The highest DHA content in flying fish was found in the brain. The (n-3) PUFA, DHA in particular, also play an important role in adaptation to changed environmental conditions and immunity to infections and parasitic diseases (Shuhnan and Love, 1999 Sargent et al., 1999).
