Evaluation of the Optimum Dietary Arachidonic Acid Level and Its Essentiality for Black Seabream (<i>Acanthopagrus schlegelii</i>): Based on Growth and Lipid Metabolism.

ABSTRACT: The aim of this study was to investigate how dietary arachidonic acid (ARA) level affects growth performance and lipid metabolism in juvenile black seabream (Acanthopagrus schlegelii). A feeding trial was conducted for 8 weeks, during which the fish (0.99 ± 0.10 g) were fed six isonitrogenous and isolipidic diets with varying ARA levels of 0.1%, 0.59%, 1.04%, 1.42%, 1.94%, and 2.42%. Fish fed the diet with 1.42% ARA had significantly higher weight gain (WG) and specific growth rate (SGR) than the other groups (p < 0.05), except for the ARA1.04. As the ARA level increased, the liver and muscle effectively accumulated n-6 polyunsaturated fatty acids (n-6 PUFAs; p < 0.05). However, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and n-3 PUFA c
