Resumo: | Mariculture in Argentina has expanded over the last years. Flounders of the Paralichtydae family are a very important fishery resource due to their abundance, meat quality, and high market price. The first mass production of juveniles of Paralichthys orbignyanus in captivity was successfully performed in 2002 at the Estación Experimental de Maricultura (EEM), Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), Mar del Plata. Moreover, it has got potential as a species for cultivation, due to its behaviour in captivity, good growth, survival and feed conversion rates. In this study, the parameters that affect this flounder cultivation under controlled conditions and in closed recirculating seawater system, are presented. Temperature, pH, and salinity recorded during the stages of On-growing and Larviculture were 18-21°C, 7.19-9.88, and 33-36.5, respectively. Larvae and juveniles were measured periodically, yielding a growth rate (TC) of 4.49% / day during Larviculture, and 2.47% / day during the On-growing stage, with a mean TC of 3.56% /day untill 147 DAH. Survival was 33.6% at 82 DAH, and 94% from 82 to 147 DPE.
