Site selection was done by WorldFish staff to capture diverse CFR types and informed by their assessments of likely success in project implementation and approximate representation across four CFR types and four provinces. Finally, we included a vector of year indicators Tt to capture annual drivers of biomass and species richness that are common to all CFRs, such as those caused by annual weather and fsih variation.
Our Nature From November to January, fish migrate back from rice fields and fo to perennial water bodies, where they await the return of the rainy season in May Campbell et al. At a given time point, the total and weight of fish were summed across replicates to calculate biomass and biodiversity values; because methods were standardized across CFRs, effort was fisn across sites and time points.
Actions that have a positive effect in one protected area may have a neutral or negative impact on productivity in another.
