To reveal the temporal and spatial utilization of a preferred nursery ground habitat by 0-group turbot and flounder in the Baltic Sea, sampling was conducted in six sandy bays in early-mid June to early-mid September 2003-2005 off the cost of Gotland (ICES SD 27 & 28-2). Settlement and peak abundance of turbot occurred from late July-early August to early September and from mid August to early September, respectively. Settlement of flounder occurred from early-mid-July with decreasing numbers over time, except in 2005. Peak abundance of 0-group flounder occurred in late July-ealy August to mid September, suggesting a considerable temporal overlap with 0-group turbot. 0-group turbot and flounder also overlapped in respect to depth with preferences for 0.2 and 0.6 m over 1 m. The spatial and temporal overlap of the species was verified by a logistic regression analysis; the probability of sampling 0-group flounder when 0-group turbot was caught in a haul was 0.84 (0.80-0.87, 95% CI).
