TY - THES A1 - Pham Tran, Duc Anh T1 - A Meta-Analysis of Fish and Crop Yields of Coupled and Decoupled Aquaponics N2 - Aquaponics is an alternative farming method that has recently gained popularity and research attention due to its potential to solve resource-related issues such as water and land scarcity. Currently, no study comparing plant and fish yields cultivated in coupled aquaponics (cAP) and decoupled aquaponics (dAP) could be identified. Meta-analyses were conducted to synthesize data extracted from studies reporting fish and plant performance in cAP and dAP. Three databases were used to identify relevant research papers published in English between 2016 and 2021. The effect size of each study was calculated using the standardized mean difference. The summary effect size and heterogeneity (I2) were computed using a mixed-effects model. However, a meta-regression or a sub-group analysis was not conducted to analyze and describe heterogeneity in greater detail. The results of the meta-analyses indicate that dAP is superior to cAP mainly in fish yields, whereas no significant difference in crop yields between cAP and dAP was observed. However, due to the presence of moderate heterogeneity in some meta-analyses, conclusions derived from the summary effect sizes of such meta-analyses should be carefully interpreted. Therefore, the conclusions should only provide an overall picture of how yields in cAP compare to yields in dAP. Y1 - 2023 ER -
