Data and code for: Microalgae-blend tilapia feed eliminates fishmeal and fish oil, improves growth, and is cost viable

Aquafeed manufacturers have reduced, but not fully eliminated, fishmeal
and fish oil and are seeking cost competitive replacements. We
combined two commercially available microalgae, to produce a
high-performing fish-free feed for Nile tilapia (Oreochromis niloticus)
—the world’s second largest group of farmed fish. We substituted
protein-rich defatted biomass of Nannochloropsis oculata
(leftover after oil extraction for nutraceuticals) for fishmeal
and whole cells of docosahexaenoic acid (DHA)-rich Schizochytrium
sp. as substitute for fish oil. Here, we provide the datasets and code
that we used to estimate the price of fish-free experimental and reference
diets of tilpia in the Scientific Reports manuscript entitled,
"Microalgae-blend tilapia feed eliminates fishmeal and fish oil,
improves growth, and is cost viable". We include the Rstudio
and supporting .csv files for a hedonic analysis of defatted N.
oculata meal and whole-cell Schizochytrium sp., non-parametric
bootstraps to estimate the median and 95% confidence intervals of
commodity and market prices for the formulated tilapia feed ingredients,
and for Fig. 2 in the manuscript.
