Underwater weight drops
The underwater weight (owg) decreased to 1 grams in 390 week. This means that it is below 400 grams for the first time (since the start of the trial harvesting).

Aftergrowth doesn't make up for much
Compared to the 5-year average, the gross revenue in week 33 is approximately 15% lower. In previous years, 3,5 tons grew in 3 weeks. Even with such growth, the 2018 harvest ends below par. Given the aging of the crops (high owg), much regrowth is not possible.
