Fish body composition

Description

This dataset contains compositional data on the proximate composition and some key minerals in the body of Atlantic salmon (Salmo salar) at the beginning and the end of a trial. The original dataset ('BodyComposition_tank') was published by Liland et al. (2024) and is from the first out of two trials ('Trial A'). Alterations to the original data structure were done by 1) converting the double-row column names into single-row column names and 2) removing the 'sex' column.

Format

A tibble with 12 rows and 14 columns:

date: date; date of data recording.
treatment: factor; treatment identifier.
tank: factor; rearing tank identifier.
dm: numeric; dry matter content of fish tissue in g/g.
water: numeric; content of fish tissue in g/g.
ash: numeric; content of fish tissue in g/g on dry matter basis.
energy: numeric; gross energy content of fish tissue in kJ/g on dry matter basis.
fat: numeric; crude fat content of fish tissue in g/g on dry matter basis.
protein: numeric; crude protein content of fish tissue in g/g on dry matter basis.
ca: numeric; calcium content of fish tissue in mg/kg on dry matter basis.
k: numeric; potassium content of fish tissue in mg/kg on dry matter basis.
mg: numeric; magnesium content of fish tissue in mg/kg on dry matter basis.
na: numeric; sodium content of fish tissue in mg/kg on dry matter basis.
phosphorus: numeric; content of fish tissue in mg/kg on dry matter basis.
