Abstract

Young Sebastes melanops live as pelagic larvae and juveniles in offshore waters, recruiting to the nearshore environment at an age of approximately six months. In the summer upwelling season, juveniles may be captured in tidepools and shallow coastal waters, where temperatures may be as low as 8°C, or in shallow estuarine habitats where temperatures reach 18°C. This study was conducted to determine the effects of temperature, ration, and fish size upon growth. Juveniles 35 to 93 mm standard length were acclimated to 7°, 12°, and 18°C and provided four daily rations (nominally 0, 25, 50, and 100% maximum ration); growth and food consumption were monitored over 57 days.
