After outplanting, blades of nori are allowed to grow for 4050 days
and then they are harvested for the first time (Sahoo and Yarish,
2005). At this point, the blades are typically between 15 and 30 cm in
length. After the first harvesting, the remaining blades are harvested
again after 1530 days. Each net can be harvested several times in a
growing season (Figure 6.8). After the crop is harvested, it is washed,
dried, cut into small pieces, and pressed by special machinery in order
to make rectangular sheets for use in sushi or to make products for
other markets (Sahoo and Yarish, 2005).
