Marine aquaculture is a swiftly growing industry that is crucial to satisfy the worldwide need for seafood. Nevertheless, traditional methods of marine aquaculture have generated anxiety regarding long-term impacts to the environment. These worries encompass the discharge of waste materials, the transmission of diseases, and the reduction of wild fish populations used to contribute to diets. With the increasing global population, it is crucial to create sustainable and environmentally friendly methods to enhance the efficiency of marine aquaculture systems and reduce their ecological footprint. Promising solutions for tackling these difficulties include innovative methods such as integrated multi-trophic aquaculture, recirculating aquaculture systems, the utilization of alternative protein sources, and the implementation of beneficial microorganisms.

Goals:
This Research Topic aims to showcase cutting-edge research and innovative practices that contribute to the development of sustainable and eco-friendly marine aquaculture. Specifically, the goals are:

1. To highlight novel techniques and technologies that enhance the efficiency of marine aquaculture operations while reducing their environmental footprint.
2. To explore alternative feed sources and sustainable feeding strategies that minimize the reliance on wild fish stocks and promote a circular economy in marine aquaculture.
3. To investigate the potential of integrated multi-trophic aquaculture systems in mitigating the release of effluents and promoting nutrient recycling in marine environments.
4. To examine the role of recirculating aquaculture systems in reducing water consumption and minimizing the discharge of waste in marine aquaculture facilities.
5. To highlight the applications of beneficial microorganisms in improving water quality, enhancing nutrient uptake, and promoting disease resistance in marine aquaculture systems.
6. To showcase successful case studies and best practices in the implementation of sustainable marine aquaculture practices worldwide.
7. To identify challenges and opportunities in the adoption of eco-friendly marine aquaculture techniques, including socio-economic, regulatory, and policy considerations specific to marine environments.

Scope:
This Research Topic welcomes original research articles, review papers, and case studies that address sustainable and eco-friendly approaches to marine aquaculture. Topics of interest include, but are not limited to, integrated multi-trophic aquaculture in marine environments, recirculating aquaculture systems for marine species, alternative feed sources (e.g., insect meal, microalgae, and plant-based proteins) for marine aquaculture, waste management strategies in marine aquaculture, disease prevention and control in marine aquaculture systems, genetic improvement of marine species, and the economic and social aspects of sustainable marine aquaculture. Contributions exploring the applications of beneficial microorganisms, such as probiotics, bioremediators, and biofertilizers, in marine aquaculture systems are particularly encouraged. Studies from diverse geographical regions and marine production systems (e.g., nearshore, offshore, and open ocean) are welcome to provide a comprehensive perspective on the global challenges and opportunities in sustainable marine aquaculture.
