Marine ecology focuses on relationships between organisms and their environment, offering insights crucial to sustainable aquaculture. Studying marine food webs, habitat needs, and ecosystem interactions allows aquaculture operators to adopt practices that minimize habitat disturbance and resource competition. Marine ecology informs on managing species diversity within farms to reduce disease transmission and enhance resilience against environmental changes. For instance, balancing herbivores and carnivores within an aquaculture system can create self-sustaining ecosystems that require fewer resources. This field guides environmentally compatible aquaculture methods, helping preserve biodiversity while supporting efficient and profitable farming practices.
