Resumo(s)
Individual growth rates, feeding rates (%BWd-1) and food conversions for cuttlefish (S. officinalis)
hatchlings and juveniles were determined during this study. A flow-through system was used. Water
temperature reached 30 °C during the hottest part of the day, gradually decreasing to 25 °C during the
night; salinity varied between 37 6 3 ppt and lights were kept on for 14 h day-1. Hatchlings were placed
in separate compartments with a water volume of 1.2 L. Juvenile cuttlefish (from 0.5 to 25 g) were
placed in bigger baskets, with a water volume of 5.2 L. Water flow was 120 L h-1. The biggest
cuttlefish used in these experiments (> 25 g) were gathered in groups of five and placed in circular
tanks (water volume of 250-300 L).
