Abstract
This case study explores the feasibility of Ulva lactuca cultivation in Jambiani, Zanzibar, Tanzania. The seaweed farming industry in Zanzibar is facing challenges related to climate change that have resulted in increased rates of crop failure and decreased production. Cultivation of the green algae Ulva lactuca has been suggested as a potential solution due to its tolerance to extreme environmental conditions. In collaboration with Marine Cultures, this project has tested different cultivation methods typically used for red algae (Rhodophyta) species. Experimental plots of Ulva lactuca were established in Jambiani, Zanzibar using the floating line and off- bottom methods. At the floating line plot, four different attachment methods were used to secure the seedlings to the lines. Tie tie and tubular netting were the most practical methods when considering the specific growth rates, percent seedling loss, and accessibility of materials. Plot location did not have a drastic effect on cultivation success, which offers flexibility for farmers with varying resources and needs. This study is significant to the local communities whose livelihoods depend on the marine environment and shows that there are avenues for the continued success of the seaweed farming industry in Zanzibar, Tanzania.
