摘要

The role of now rate in large-volume production units (2800 L silos) for Atlantic halibut, Hippoglossus hippoglossus L., larvae was studied. Correlations between now rate, bacterial numbers (a measure of water quality), the larval growth and development rates, and mortality were assessed. The experiment included a total of six silos, two each at three different flow rates. Flow rate and mortality were positively correlated: the number of dead larvae on day 30 was highest (i.e, 2200 and 2000) in the silos with highest now rate (8 L min(-1)) and lowest (i.e. 1300 and 1200) in the silos with the lowest flow rate (2 L min(-1)). Larval weight was negatively correlated with flow rate: on day 30, the mean dry weight was 968 mu g in the silo with the lowest flow rate and 820 mu g in the silo with highest now rate, Yolk sac utilization efficiency was 92% in the silo with the lowest now rate and 72% in the silo with the highest now rate. The number of bacteria were highest (2.7-10(6) mL(-1)) in the incubators with the lowest now rate.
