growth interspecific differences laboratory rearing spatial distribution substrate preferences
Juvenile Pacific halibut reared in the laboratory grew at a faster rate and had a more uniform distribution in behavior tests than juveniles of yellowfin sole and rock sole. Juvenile yellowfin sole and rock sole had similar 90-d growth rates (0.71-0.83% BWD) in the laboratory at 10degreeC, whereas Pacific halibut grew significantly faster (1.29% BWD). Rock sole grew the same on both mud and sand, despite a known preference for sand substrate in the field. Yellowfin sole and rock sole had an aggregated distribution in the tanks as measured by nearest-neighbor analysis regardless of the presence of other species, whereas Pacific halibut had a uniform distribution. These are the first observations of growth and behavior of juveniles of these species in the laboratory
