Abstract
- Juvenile turbot Scophthalmus maximus (L.), ranging in size from 30 to 407 g were graded into small, large, and unsorted groups in a low-water-level raceway system. Water depth was 7 cm. The rearing design proved self-cleaning and well suited for turbot ongrowing. Mean initial weights 146.2, 236.1, 162.7 g increased to 299.1, 465.6 and 343.1 g in the small, large, and unsorted groups respectively during the 86 day experiment. The corresponding SGRs were 0.84, 0.79 and 0.87% day-1. No positive effect of grading on biomass production was revealed. The coefficient of variance gave no indication of social interactions, but plotting the start weights against estimated individuals SGRs did, although the effect was minor.
