If we take into consideration biomass variability, we see that around 1996, stocks totalled 103,000 tonnes. Levels have declined to 58,000 tonnes. We do not control the extent to which stock levels vary. Scientific evaluations may or may not allow us to gauge these variations. Something may have happened this year to cause stocks to decline. Over time, we have observed a gradual decline, but this year, levels dropped dramatically. No one was expecting this to happen.
