Silvery-black porgy (Sparidentex hasta, Valenciennes 1830) is recognized
as a potential species for aquaculture diversification in the Persian
Gulf and Oman Sea, because of its good adaptation to captivity, rapid
growth and high market price (Pavlidis and Mylonas, 2011). Consequently,
efforts are focused on establishing the nutritional requirements
of the species and optimizing diet formulation. In this context, the
nutritional requirements for n−3 LC-PUFA for this species have been
estimated to be between 0.6 and 0.8% (Mozanzadeh et al., 2015a);
thus, we hypothesized that feeding with alternative lipid sources solely
or in combination with FO, would maintain growth performance if the
EFA levels were provided in the diets. The aim of this study was to evaluate
the growth performance, chemical composition, particularly lipid
and FA composition, feed utilization and health condition in silveryblack
porgy fed experimental diets in which FO was partially or totally
replaced by alternative lipid sources (sunflower oil, canola oil and
