ABSTRACT: Both temperature and food availability have significant effects on the growth and survival of native fishes, particularly during early developmental stages. Therefore, we reared larval green sturgeon (initial age ca. 27 days post hatch) at four different temperatures (11, 14, 17, and 20°C) and two different food rates (100% and 40% of optimal) to assess the effects of these stressors and their interactions on larval growth. We compared the overall size (fork length, total length, and mass), specific growth rate (cm/day), and condition factor of larval fish after being held in rearing conditions for up to 12 weeks. Our results can be used to develop models of the early life history requirements of green sturgeon and to inform management actions seeking to increase larval and juvenile recruitment success.
