Crecimiento y rendimiento en carne del Lenguado Paralichthys orbignyanus (Valenciennes, 1839) cultivado en Argentina
The results of the final on-growing (500 g to 1 kg)of flounder Paralichthys orbignyanus under closed recirculated water systems and controlled conditions are presented. 22.5 percent of fish reached 1 kg alter 2.1 months of starting the on-growing trial. Sex ratio was 20.6 percent females and 79.4 percent males. Average length for females and males was 38.53 ± 4.58 cm TL and 32.52 ± 5.25 cm TL, respectively. Average body weight for females and males was 710.58 ± 262.95 g and 427.59 ± 203.01 g, respectively. Statistically significant differences were found for average length for sex (p0.01)and for average body weight for sex (0.01 0.05). Flesh yield was 43.1percent fillets without skin and 57percent fillets with skin. Flesh of cultivated flounder had a higher proportion of lipids and humidity than flesh of wild flounder. The present study shows the aquaculture potential of flounder Paralichthys orbignyanus and the higher growth of females suggests the convenience of monosex culture
