Article Synopsis
- * The study identified the challenges posed by climate change to Tanzania's artisanal fishing, marine protected areas, and seaweed farming, emphasizing the need for careful marine spatial planning to enhance climate resilience.
- * By analyzing climate resilience and potential areas for growth over the next 20 to 40 years, the research suggests that effective strategies can help coastal communities adapt, create economic opportunities, and support biodiversity, but highlights the necessity of reducing global emissions to secure a sustainable future.
Algal blooms are increasing worldwide, driven by elevated nutrient inputs. However, it is still unknown how tropical benthic algae will respond to heatwaves, which are expected to be more frequent under global warming. In the present study, a multifactorial experiment was carried out to investigate the potential synergistic effects of increased ammonium inputs (25 μM, control at 2.

The samples were collected in five study sites in Tanzania: Tumbe, Chwaka, Paje, Bweleo in Zanzibar islands and Songosongo Island, mainland Tanzania, where skin irritation problems were observed in seaweed workers in an earlier study. The cyanobacteria from the Moorea genus were microscopically detected in the seawater, with highest concentrations in the months with the highest seawater temperature or hot dry season, than in the other two seasons.

- Aquaculture is developing differently across Madagascar, Tanzania, and Indonesia, with Madagascar focusing on small-scale community-based aquaculture and Tanzania having a 30-year history in red seaweed cultivation, although both face challenges from environmental impacts and climate change.
- In Madagascar, a successful contractual model for farming seaweed and sea cucumbers exists, supported by NGOs aiming to combat coastal degradation, while Tanzania's seaweed farming has a relatively mild ecological impact compared to shrimp farming.
- Indonesia faces multiple challenges in aquaculture, including pollution and disease, prompting government initiatives for improvement, while models like Integrated Multi-Trophic Aquaculture (IMTA) and community-based approaches could provide frameworks for success in these regions.
The rapid expansion and globalization of the seaweed production industry, combined with rising seawater temperatures and coastal eutrophication, has led to an increase in infectious diseases and pest outbreaks. Here, we propose a novel Progressive Management Pathway for improving Seaweed Biosecurity.

A trout (Onychorynhis mykiss) gill epithelial cell line (RTgill-W1) was used to determine the cytotoxicity of rotenoids and effects on cell metabolism.
