Since the 1990s size-limited catch has remained relatively stable; non-size-limited catch increased. Spawning stock biomass estimates remained above the soft limit with stable spawning biomass and vulnerable biomass from the mid-to-late 1990s. Projections predict that continued harvest at constant current catch levels would likely lead to vulnerable and spawning biomass declines.
