Rusty dab, Sandy dab
Yellowtail flounder are concentrated mainly in Div. 3N and the bordering areas of Div. 3O and to a lesser extent the border of Div. 3LN, similar to most years in the time series. As stock size increased from the low level in the mid-90s, the stock expanded northward and continues to occupy this wider distribution. This expansion coincided with warmer temperatures; temperatures continue to warm, and will likely not limit the stock distribution in the near future. Despite the increase in stock size observed since the mid-90s, length at which 50% of fish are mature has been lower for both males and females in the recent period. There also seems to have been a slight downward trend in weight at length since 1996. The cause of these changes is unknown (Parsons et al. 2015).
