Wildemania amplissima is under development for sea vegetable aquaculture. Ideally, it will join other economically valuable Bangiales (e.g., Pacific nori, Atlantic laver) to advance aquaculture. Native to Maine, Wildemania’s fast growth during summer makes it an ideal candidate to enable year-round aquaculture. I collected zygotospores from wild blades and successfully established the sporophytic phase (“conchocelis”) on oyster shells in culture. These new cultures will permit future experiments to determine the temperature and photoperiod needed to complete the life history and to produce conchospores needed to seed lines.
Predation by ciliates on algal seed stock is one of the most serious issues affecting nurseries in the aquaculture industry. I tested two chemicals (betadine and quinine) known to kill ciliates against adult sea vegetables, their seed stock stages, and ciliates isolated from algal seedstock grown in the University of Maine’s Organic Sea Vegetable Nursey, at the Center for Cooperative Aquaculture Research (Franklin, ME). I then tested extracts from Artemisia annua (sweet annie) for their potential as an anti-ciliate treatment against these same targets.
