Data and code for: Microalgae-blend tilapia feed eliminates fishmeal and fish oil, improves growth, and is cost viable
收藏资源简介:
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.
