| Abstract |
Seaweed farming is a green and sustainable way to produce food and to protect the marine environment. In this study, we examined how large-scale cultivation of Sargassum fusiforme affects seawater quality and tiny plant-like organisms in the ocean called phytoplankton. These organisms are important because they form the base of marine food chains. We collected water samples during both farming and non-farming seasons. The results showed that S. fusiforme farming helped raise oxygen levels and made nutrient concentrations, such as nitrogen and phosphorus, less excessive. Farming also helped reduce the overgrowth of certain dominant species and supported a more diverse and balanced phytoplankton community. We used microscopes to observe and to count the phytoplankton. Our findings show that seaweed farming can improve ocean health and can offer useful guidance for sustainable aquaculture and coastal ecosystem protection. |
