Abstract

The present study assessed the percentage of survival and metamorphosis of larval stages of Caligus rogercresseyi [1] nauplius I to nauplius II, and nauplius II to copepodite, conducting bioassays in triplicate with 50 larvae each, nauplius I or nauplius II, at temperature of 12°C, 15°C and 18°C; salinity 20, 23, 25, 27, 29, 31, 33 and 35 g/L and oxygen saturation with ranges between 30-60%, 90-100% and 190-200%. Bioassays were performed in station Quillaipe of Fundación Chile, Puerto Montt, Chile. It is concluded that the temperature is inversely proportional to the time of metamorphosis and survival of the larvae of Caligus rogercresseyi. In salinity is observed that increased this, greater is the percentage of survival and metamorphosis is faster, while the larvae do not survive less than 20 g/L. Oxygen saturation ranges indicate that the larvae do not survive at saturations between 30-60%, and it had no differences between 90-100% saturation and 190-200%.
