ISSUE FOCUS FEED & ADDITIVE MAGAZINE August 2025 81 gestion, leading to better feed conversion ratios and overall growth performance. Feeding Strategies: To optimize SDA, implement feeding regimes that align with the metabolic rhythms of the cultured species. For example, feeding during times of peak metabolic activity can maximize nutrient uptake and minimize energy wastage associated with SDA. FUTURE DIRECTIONS AND RESEARCH Advancements in SDA Monitoring The advances in SDA monitoring are enhancing our understanding of metabolic processes in aquaculture and contributing to the development of more sustainable and efficient feeding practices. By integrating cutting-edge technologies and interdisciplinary approaches, researchers and aquaculturists are working towards maximizing metabolic efficiency and minimizing environmental impacts in aquaculture operations. some of the recent advancements include; • Real time monitoring technologies • Biochemical markers • Nutrigenomics • Remote sensing techniques • Integrated multi-trophic aquaculture (IMTA) system CONCLUSION In conclusion, the study of specific dynamic action in aquaculture offers valuable insights into the metabolic responses of cultured species to feeding, with significant implications for feed efficiency, growth performance, and environmental sustainability. By understanding the energy expended during digestion and processing of food, aquaculturists can optimize feeding strategies, improve feed conversion ratios, and minimize environmental impacts. By integrating recent advancements in SDA monitoring into aquaculture practices, we can strive towards more sustainable and efficient production methods, ensuring the long-term viability of aquaculture as a vital source of nutritious food for a growing global population.
