Sustainable Algae Mariculture

  Algae Europe December 2022

A UC Davis Aquaculture class took a trip to Monterey Bay Seaweeds recently to learn about sustainable algae mariculture practices for a land-based seaweed and kelp farm that sells fresh, raw seaweed.

Their host was Dr. Michael Graham, a professor at San Jose State University, which is part of the California State University System and is stationed at the Moss Landing Marine Laboratory.

The visiting students recorded underwater video of seaweed tumble culture: sea lettuce (Ulva), California nori (Porphyra), dulse (Palmeria), red sea grapes (Botryocladia), bull kelp (Nereocystis) and giant bladder kelp (Macrocystis).

Monterey Bay Seaweeds is also involved in other low trophic aquaculture farming and participates in the endangered species conservation aquaculture of white abalone, which are giant sea snails. The students saw baby abalone and inspected fish tanks with abalone and Ulva lactuca which some may refer to as integrated multi-trophic aquaculture (IMTA).
