Cultivating and breeding acid-resistant sea cucumber varieties is one direction, and the tolerance of sea cucumbers to low pH environments can be improved through manual selection. At the same time, a multi-nutrient-level integrated aquaculture model (IMTA) is developed, such as the mixing of seaweed or filter-feeding shellfish, and the use of algae photosynthesis to increase the pH of water and the dissolution of shellfish shells to provide alkalinity buffer, thereby reducing the acidification effect of aquaculture water. In addition, it is also crucial to strengthen monitoring and habitat protection of wild sea cucumber populations, and healthy and diverse ecosystems tend to have stronger acidification resistance.

Future research needs to be comprehensively promoted across disciplines, including collaboration in the fields of marine chemistry, ecology, physiology and genomics. In addition to laboratory control tests, the response mechanism of sea cucumbers under long-term progressive acidification and multiple stresses (such as heating, hypoxia, etc.) should also be evaluated in combination with on-site observation and model simulation. Through the above efforts, the impact of marine acidification on tropical sea cucumbers and their ecosystems can be more comprehensively understood, providing scientific support for protecting marine biodiversity and maintaining ecosystem service functions.
