Physical and chemical characteristics of Euphausia superba.

Average (± 1 SD) physical and chemical characteristics of adult non-gravid, gravid, and all (non-gravid and gravid) Euphausia superba krill prior to the start of the experiment (T0 samples). WW, wet weight; DW, dry weight; C, carbon; N, nitrogen; %POC, percent particulate organic carbon; %PIC, percent particulate inorganic carbon; MDH, malate dehydrogenase and LDH, lactate dehydrogenase activity, in activity (U) per gram WW. Sample size, n, for length and WW was 10 for non-gravid and gravid krill and n = 20 for all krill; n = 2 for DW for non-gravid and gravid krill and n = 4 for all krill; n = 2 for C/N content parameters (%C, %N, %POC, C:N [molar], POC:PON [molar], and %PIC) for non-gravid and gravid krill and n = 4 for all krill (with subsample homogenates [n = 2] analyzed for each krill); n = 3 for protein and MDH for non-gravid and gravid krill and n = 6 for all krill.
