Quantifying dietary phosphorus requirement of fish – a meta-analytic approach
A meta-analysis of available data on dose response to dietary phosphorus (P) in fish from over 70 feeding trials reported in 64 published studies covering over 40 species of fish was performed. Broken-line regression was used to model the data sets. The meta-analysis showed that estimated minimal di...
