adjusted to maximize uptake of N by P. umbilicalis
(Kraemer et al., 2004; Carmona et al., 2006). Lastly, the
nets can be desiccated, as needed, to control epiphytic
growth (Sahoo and Yarish, 2005).
This study demonstrates the feasibility of neutral
spore-seeding of nori nets with a native Maine species of
Porphyra and points to some areas where further methodological
improvements are needed for crop development.
At the nursery stage, joining the raceway to partial
make-up flow from land-based, cold-water, fish aquaculture
(e.g. salmon, halibut) would eliminate the need for the
addition of fertilizer whilemaking it possible tomaintain a
lower temperature of the seawater in the raceway, even in
summer, without the added expense of a chiller system.
The methods in this study could be integrated with both
land-based and nearshore aquaculture
