Effects of dietary arachidonic acid on growth performance, survival, immune response and tissue fatty acid composition of juvenile Japanese seabass, Lateolabrax japonicus

Towards the optimization of performance of Atlantic salmon reared at different water temperatures via the manipulation of dietary ARA/EPA ratio

“…This observation is in agreement with previous studies reporting the importance of ARA in Atlantic Salmon (Stubhaug et al, 2005;Tocher et al, 2000), the dietary inclusion of which, nevertheless, must be properly balanced with the inclusion of dietary EPA towards maximising performances in Atlantic Salmon diets. The results of this study complimented other teleost fish studies showing the positive effect of dietary ARA in fish (Atalah et al, 2011;Boglino et al, 2012;Luo et al, 2012;Xu et al, 2010) and contrary, other studies have shown that dietary ARA did not affect fish growth (Copeman et al, 2002;Fountoulaki et al, 2003;Koven et al, 2001). Based also on the results achieved in the present study, which D-ARA/EPA outperformed the other treatments, it seems possible that these discrepancies reported for growth related effects of dietary ARA may likely be related to the interaction with dietary EPA.…”

“…Previous studies have shown the role of ARA mediation on the eicosanoid cascade with the concomitant regulation of overall fish physiology including maturation, endocrinology and health stress response. Accordingly, dietary ARA supplementation has increasingly received consideration for possible functional feed formulation (Alves Martins et al, 2012;Norambuena et al, 2013c;Tian et al, 2014;Van Anholt et al, 2004;Xu et al, 2010). However, and to the best of authors' knowledge, it is surprising to note that this study is the first to assess the effects of dietary ARA on performance and fatty acid composition in juvenile Atlantic salmon.…”

“…For example, in juvenile eel (Anguilla japonica) dietary ARA inclusion has been shown to be essential for normal growth (Bae et al, 2010), and similarly the importance of dietary ARA inclusion in larvae of sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata) has been reported (Atalah et al, 2011;Bessonart et al, 1999). In juvenile Japanese seabass (Lateolabrax japonicus) and juvenile Synechogobius hasta it has been shown that dietary ARA significantly enhanced growth and protein content of the whole body and the liver (Luo et al, 2012;Xu et al, 2010). In contrast, larvae of gilthead seabream (Sparus auratus) showed high dietary ARA resulted in negative effects on growth and increased mortality (Copeman et al, 2002;Koven et al, 2003).…”

Influencia del α tocoferol en la incorporacion y peroxidacion del acido araquidonico en alevines parr de salmon del Atlantico (Salmo salar L.)

“…Dado que el ARA es un componente menor de las membranas celulares y requerido en pequeñas cantidades, comparado con el DHA y el EPA, su importancia ha sido subestimada (Bell et al, 2003;Xu et al, 2010). Sin embargo, los escasos trabajos existentes con ARA, sugieren su importante contribución al crecimiento y supervivencia, así como su influencia en el perfil de ácidos grasos en los tejidos en una cantidad importante de peces teleósteos (Castell et al, 1994;Bessonart et al, 1999;Estevez et al, 1999;Xu et al, 2010).…”
