The effect of culture density on production characteristics and body composition of Florida
pompano Trachinotus carolinus reared to market size using recirculating aquaculture systems (RASs)
maintained at a salinity of 5‰ was evaluated in a 110-d growth trial (water temperature = 27.0–28.58C).
Juvenile Florida pompano (mean weight 6 ± SE = 259.0 ± 3.0 g) were stocked into two tanks from each of
four separate RASs at an initial nominal density of 6.5 (low density) or 13.0 kg/m³ (high density), equivalent
to 200 and 400 fish/tank, respectively. After stocking, fish were fed a 4.7-mm, floating pelleted diet (50%
protein, 14% lipid) twice daily at a targeted daily feed rate of 3% body weight per day. At stocking and at 3-
week intervals thereafter, 10% of the fish population of each tank was sampled to determine production
characteristics, including mean weight, weight gain, specific growth rate, absolute growth rate (AGR), feed
conversion efficiency (FCE), biomass, and survival. At termination, fish in all tanks were harvested to
determine production characteristics and samples were obtained to determine whole-body composition,
energy retention, protein efficiency ratio (PER), protein productive value (PPV), hepatosomatic index,
gonadosomatic index, and fillet yield.
