carried out on the physiological ecology of species of
Porphyra from southeast Alaska. Species were
collected from various field sites near Juneau, Sitka,
Metlakatla and Kachemak Bay. Conchocelis cultures were
started and maintained as both free and shell cultures.
Environmental conditions for conchocelis maturation and
spore release were investigated. Growth experiments
were carried out on the microscopic conchocelis phase
of three species. Multi-factorial experiments assessed
the interactive effects of light intensity, salinity and
temperature on growth. Preliminary experiments that investigated
the effects of light intensity, salinity, temperature
and nutrients on the growth of young Porphyra torta
blades were performed. Porphyra torta was outplanted
during the summer and fall. Some efforts were made for
outreach and technology transfer with Alaskan native organizations.
It is anticipated that the project will require at least
an additional year of work before objectives are met.
