Rapid climate change and the disruption of breeding grounds threaten fish reproduction and survival, putting sustainability at risk across wild marine environments and aquaculture systems. In response to the complex biological challenges of fish reproduction under changing climates, adaptive management strategies are proposed. These strategies integrate technological advancements using non-invasive and non-lethal methods to monitor fish populations safely. Additionally, assisted reproduction and nutrigenomics approaches are outlined as potential interventions to mitigate climate-induced reproductive risks. By implementing these innovative monitoring and biological tools, aquaculture operations can be better supported. This helps maintain fish farming as a reliable source of human nutrition and protects the livelihoods that depend on aquatic production in the face of ongoing global environmental shifts.
Fish provide essential nutrition and support livelihoods worldwide, but environmental disruptions threaten their ability to breed successfully. Exploring non-invasive monitoring along with advanced reproductive and nutritional techniques helps ensure that aquatic systems remain resilient. Protecting fish reproduction under changing climate conditions is vital for long-term food security and the economic survival of communities reliant on aquaculture.
The proposed approaches could enable aquaculture operators and fisheries managers to adopt non-invasive monitoring tools, assisted reproduction protocols, and nutrigenomics-based interventions to improve fish breeding success. However, because the abstract outlines these strategies at a conceptual and management level without reporting specific trial data or validated prototypes, the work appears to be at an early, conceptual stage of research and development.

The ongoing rapid climate change, combined with the disturbance of fish breeding grounds, may impact reproduction by endangering successful breeding and survival, and thus affect the viable sustainability in aquaculture systems as well as in the sea. In this study we focus on the biocomplexity of fish reproduction in response to climate change. Further, we propose adaptive strategies, including technological advancements, using a noninvasive and non-lethal approach, and we outline an assisted reproduction and nutrigenomics approach to mitigating fish reproductive risks posed by climate change. This was done in an effort to monitor fish aquaculture and ensure that, as a livelihood, it may provide a useful source of nutrition for our society.
