Since the primary objective of this experiment was to develop design protocols for an integrated catfish–vegetable hydroponic system, catfish growth trial was not replicated. Results showed that hybrid catfish grew steadily over the 233 days from an individual initial weight of 6.58±1.72g to a final mean body weight of 247.23±108.7g. The gross and net yields of catfish from 226m2 pond were 7.01 and 6.78kgm−2, respectively. Specific growth rate (SGR %), % survival rate (SR %) and food conversion ratio (FCR) of fish were 1.56% day−1, 80.09% and 2.29, respectively (Table 4).
