摘要

Marine co-cultivation offers a promising avenue for sustainable aquaculture; however, its success is driven by a complex interplay of biotic and abiotic factors inherent to the marine environment. Consequently, integrated knowledge is essential for creating effective aquaculture systems. This study aims to understand the environmental factors affecting the red seaweed Gracilariopsis tenuifrons cultivated around a mussel farm for biomass production. Seaweeds were cultivated at four locations around a mussel farm (P1, P2, P3, and P4), and at each location, at two depths (surface and 1 m). Environmental parameters (light, nutrients, and circulation) were characterised. P1 and P4 exhibited the highest growth rates, associated with a higher presence of nutrients from the mussel farm brought by the circulation. Depth significantly influenced seaweed growth, with rates at the surface being greater than at deeper depths. Our findings emphasise that a deeper yet accessible understanding of environmental attributes can enhance the eco-efficiency of aquaculture.
