Abstract

Paralichthyds are the most economically important fish in the Southern Atlantic due to their abundance, flesh quality, high market price and increasing fishery demand. In Argentina, the first juvenile mass production of flounder Paralichthys orbignyanus i orbignyanus follow those described for olivaceus. At 40 days post-hatching (dph) and 798 degrees-days, juveniles measured in average 11.6 +/- 0.5 mm. Mean survival rate after 142 dph was 49.7%. More than half of the total juveniles obtained (59.1%) were albino, whereas 15.5% were normally pig orbignyanus juvenile mass production.
