Table 4 Various dietary indices derived from the midgut gland FAs of four crab species sampled in Taiwan. The dietary indices reflect the consumption of carnivorous diet (ICa), Chlorophyta (ICh), Phaeophyta (IP), Rhodophyta (IR), and Bacillariophyceae (IB). All values are means ± SD (n = 12 for each species)
