Spreadsheet of weight, length and sex of fish sampled after feed switch between vegetable and marine oil, in September 2015 (freshwater) and January 2016 (seawater).

Spreadsheet columns are:

• Date (YYYY-MM-DD)
• Day (day zero is the day before first feeding with new feed)
• Inputter (person entering data into Excel)
• Tank (1, 2, 4, 5 with Atlantic salmon, 3 and 6 with rainbow trout)
• Section (tanks were divided in half using perforated walls)
• Treatment (explained in sheet "treatments")

CPM is a descriptive measures for the expression level of a gene.

Salmon feed experiment: Lipidomic data (POS mode) of liver samples from fresh water sampling.

Positive mode metabolomics of liver samples from saltwater sampling.

Positive mode metabolomics of the same muscle tissue sample at multiple levels of dilution.

Samples of 40 45 50 55 60 mg were diluted in the same volume, then analysed. The resulting data describe the same tissue at different levels of dilution. From this we can devise some numerical post-processing that would make all samples "similar" based on the mass of tissue. This post-processing could then be applied to later samples given their mass.
