This study was conducted to investigate the effects of maternal inherited immunity acquired from crustacean‐enhanced diets on the vitality and profitability of sea bass offspring. Newly hatched larvae produced from three groups of broodstock were evaluated. The broodstock were fed (a) a basal diet (BD), (b) a Palaemon ‐supplemented diet (PSD), and (c) an Artemia ‐supplemented diet (ASD) for 42 days. A total of 400,000 larvae at 3 days posthatch (DPH) produced from each treatment were stocked in larval rearing tanks at 40 larvae/L for 42 days. Survival (%) was improved by 37 and 9.96% in the groups fed ASD and PSD compared with the control group. The growth, swim bladder (%), and condition factor all significantly ( p ≤ 0.05) improved in the postlarvae produced from broodstock enhanced with crustacean diets. Compared with the BD group, the serum lysozyme activities of the fish groups fed ASD and PSD increased by 45.6 and 11.7%, respectively. Sea bass fry (90DPH) produced from broodstock fed ASD showed the best tolerance to salinity/temperature stress tests. Furthermore, the profitability improved in ASD and PSD compared with the BD group. In conclusion, sea bass broodstock enhanced with Artemia biomass produced offspring of superior quality with less cost and greater profit margins.
