Aquaculture ponds, often overlooked in national carbon budgets, present a valuable opportunity for carbon storage. This study explores the carbon absorption rate of pond sediments in relation to fish species selection, pond age, and fish farming management. We employed a standardized soil sampling protocol, using a hand core sediment sampler to collect 200g-300g soil samples from approximately 20 cm depth ( methodology adapted from Gilbert et al, 2021)) . All samples were collected by the same individual to ensure consistency. Soil analyses were performed at the Oklahoma State University Soil Testing Lab. Channel Catfish (n=4), koi (n=2), and bluegill (n=2) fish-pond soils were sampled. Additionally, a questionnaire captured data on physical and chemical parameters and fish farming management practices.Our r esults indicated that c arbon absorption rates varied significantly among fish species selections. Bluegill fishponds exhibited the highest organic matter (%) and total carbon (%) content in both dry and wet conditions, followed by catfish and koi ponds (Figure 1) . Furthermore, carbon absorption rates were assessed in relation to pond age and various management factors (stocking rate, feed, total production). Once again, bluegill fish-ponds showed the highest carbon absorption rates, followed by catfish and koi ponds. This study underscores the potential for optimizing carbon storage in aquaculture ponds and highlights the importance of considering fish species selection, pond age, and fish farming management practices in carbon sequestration strategies. These findings contribute to our understanding of carbon dynamics in aquaculture systems and their relevance in addressing the challenges posed by changing climate patterns.
