An evaluation of training strategies for trairao fingerlings was carried out. The experimental design included six 20 L tanks with artificial aeration, controlled temperature variation (27+/-0.5degreesC), and continuously darkened (0L:24D), except during daily management. Fingerlings with 2.9+/-0.2 cm long were kept at a 4 specimens/L and were allotted to the following treatments: the first was direct offering of artificial diet and the second involved training strategies by means of the replacement of semi humid food for dry food. At the end of the experiment, average survival rates were 27.5 and 96.66% for the first and second treatments, respectively, demonstrating that feeding conditioning is an efficient management in production and survival of Hophas cf. lacerdae fingerlings.
