Mendez and Alvarez-Castaneda (2000) gave comparative analysis in the liver of two species of ichthyophagous
bats and reported the heavy metal load as (ug/g in dry weight) 133 (Zn), 27.4 (Cu), 1.25 (Pb), 6.5 (Cd) for Myotis vivesi and 57 (Zn), 13.1 (Cu), 0.57 (Pb), 8.0 (Cd) for Noctilio leporinus.
Despite being considered an ichthyophagous
predator with a marked preference for sardines (Sardinops caeruleus) during the cold season, it can alternate its diet to consume mainly euphausiids (Euphasia distinguenda) during the warm season.
Further, the 'tucunare' (Cichla sp.) is an ichthyophagous
fish of the Amazon river basin, and a rich source of essential fatty acid: linolenic acid n-3 series and linoleic acid n-6.
Thus, they are useful in trophic ecology studies of ichthyophagous
animals (CORREA; VIANNA, 1992; DI BENEDITTO; LIMA, 2003).
Furthermore, otoliths can resist the passage through the digestive tract of ichthyophagous
species because of their low degradability.
sierra is a carnivorous ichthyophagous
predator in the coastal pelagic zone, consuming mainly species from the families Clupeidae and Engraulidae, and a lower proportion of cephalopods (squid).
Fish community resource partitioning shows that the components are organized in three guilds: ichthyophagous
, carcinophagous and omnivorous.
The larger members of this group are definitively ichthyophagous
(fish-eating) and eat the smaller pelagic species.
