Atlantic croaker (Micropogonias undulatus) is a medium-sized marine carnivore that has a market as both baitfish and foodfish, but research on their aquaculture is limited, particularly on feed management. In this 8-week feeding trial, Atlantic croaker (initial weight of 14.0 g) were fed to apparent satiation (AS) twice daily compared with a fixed feeding ration at 5% body weight (body weight) fed feeding frequencies (FF) x2, x3, x4 or x5 daily and the growth, feeding efficiency, various body indices as well as whole-body proximate and fatty acid composition. Results showed that feed intake in the AS treatment corresponded to ~ 2.65% BW with no significant growth difference compared to the other FF treatments at 5% BW. However, the FCR was significantly better in AS compared to all other treatments. The K, VSI, and HSI were significantly higher in the AS treatment compared to the FF x2 treatment. Histological observations and scoring revealed significantly more hepatic vacuolization that is consistent with excessive lipid deposition. Intestinal histomorphological observations and scoring were not significantly among treatments. Similarly, there were no significant differences in the whole-body proximate composition or fatty acid profile in Atlantic croaker among treatments. Results demonstrate that 5% BW/day was excessive and this overfeeding whereas feeding at AS (~ 2.65% BW/day) was sufficient to maintain similar growth, feeding efficiency and is likely to be a more practical strategy for Atlantic croaker juvenile production.
