Fig. 4From: Vitellogenesis and changes in lipid and protein content of oocytes of Trophon geversianus (Neogastropoda: Muricidae) in Golfo San José (Chubut, Argentina)Monthly variations in lipid index (LI) and protein index (PI) in oocytes of Trophon geversianus. a LI annual variation (mean ± SE, n = 4–5). Significant differences in LI between months are indicated with different symbols (Asterisks, filled diamonds). b PI annual variation (mean ± SE, n = 3–4). No significant differences were found in PI between monthsBack to article page
