The product structure also needs to be upgraded. It can no longer rely on low-priced raw materials, but should develop towards branding and high added value (Bo et al., 2024). Internationally, Southeast Asian countries are also accelerating their layout in porphyra cultivation, and the competition in the future will not be easy. Whether China can maintain a leading position in technology and management will determine the pattern of its porphyra industry. 8.3 Future directions and integrated management recommendations For the porphyra industry to truly "thrive in the long term", it needs to take multiple approaches simultaneously, with policies, technologies and markets all working in coordination. Technological innovation remains key, especially the breeding of new varieties and the promotion of intelligent breeding systems, which can increase production while reducing risks. At the policy level, it is possible to consider improving disaster insurance and price control mechanisms to help farmers stabilize their income. In terms of layout, the breeding area should also be rationally planned based on the environmental carrying capacity to avoid ecological problems caused by excessive development. The market competition is fierce. Quality and brand have become new moats. Strict quality control can win the trust of consumers. At the same time, international cooperation and popular science publicity should not be ignored either, as they can expand influence and enhance public support for ecological breeding. Ecological priority, innovation-driven development, and collaborative governance, these three points may sound cliched, but only by persisting can the porphyra industry move forward steadily, increase fishermen's income, boost the coastal economy, and achieve a true win-win situation while protecting the Marine ecology.
