CO₂ and CH₄ Fluxes in Tilapia (Oreochromis niloticus) and Grass Carp (Ctenopharyngodon idella) Earthen Aquaculture Ponds
Description
This dataset contains measurements of CO₂ and CH₄ fluxes from aquaculture ponds over a complete 13‑month production cycle. Data were collected in monoculture systems of Nile tilapia (Oreochromis niloticus), monoculture systems of grass carp (Ctenopharyngodon idella), and polyculture systems combining both species. The dataset includes monthly and diel variations in greenhouse gas emissions, as well as calculations of the carbon footprint expressed in kg CO₂eq per kg of fish produced. Files are provided in CSV and XLSX formats, enabling statistical analysis, replication of results, and comparison with other aquaculture emission studies.

Steps to reproduce
CO₂ and CH₄ fluxes were measured monthly in nine earthen aquaculture ponds stocked with Nile tilapia, grass carp, or both species over a 13‑month production cycle. Diffusive fluxes were quantified using floating chambers connected to a portable GHG analyzer, while ebullitive fluxes were measured with bubble traps deployed for 24 hours. Diel variability was assessed with 24‑hour sampling at 4‑hour intervals. Raw data are provided in CSV and XLSX formats, including pond type, sampling date, gas fluxes, fish biomass, and calculated carbon footprint.
