Results Throughout this section, the fishmeal-based aquafeed is referred to as the control treatment, and the plant-based aquafeed is referred to as the allernative treatment. odd-numbered replicates (1.3 and 5) received the control treatment, and replicates (2,4 and 6) received the alternative treatment. Over the course of the 60-day trial, observations water temperature all replicates ranged from 22.0 to 27.3 eC with a mean of Fish growth Although the experiment was not designed to evaluate the effect of aquafeed treatments on tilapia growth, fish biomass per replicate was measured on days l and 60 of the trial. Based on normalized data, the mean (+SD) net growth values (wet weight) per replicate for the control and alternative treatment groups were 347.5 91.2) g and response between H the difference in the fish productivity was not considered appropriate given the short duration of the trial relative to treatments the typical fish grow-out period. Plant growth Table 1 summarizes the normalized plant growth data per treatment group. The alternative treatment group experienced higher mean plant growth in terms of all observed parameters: height, leaf biomass. During the trial, unanticipated plumbing problems in replicates 5 and 6 substantially reduced plant productivity in these two units (see "Dis- cussion" section). In order to account for this variability, the affected units were assigned ANCovA showed significantly higher p
