Ecology Summary - Anguilla anguilla

Taal:

Hoofdreferentie	Deelder, C.L., 1984
Opmerkingen	Observed transients in the intertidal zone (Ref.49162). Observations have shown that scent and taste appear to be more important than sight for foraging purposes (Ref. 172). Smaller individuals feed mainly on insect larvae, molluscs, worms, and crustaceans; subadults on benthic invertebrates and fish (Ref. 51442); larger individuals on other fishes. This species can also be a scavenger, feeding on carcasses. Yellow and silver eels are nocturnal and opportunistically feeding on virtually all small animals they encounter. Cannibalism occurs amongst yellow eels (Ref. 172). Feeding ceases when silver eels start their spawning migration and rely on their lipid reserves for energy. Leptocephali feed on gelatinous zooplankton (e.g. Hydrozoa, Thaliacea and Ctenophora) (Ref. 89143). Based on next-generation 18S rRNA gene sequencing, Hydrozoa (mostly siphonophores), dominates the leptocephali larvae diet (at least 75%), while copepods and euphausiids are less abundant (7%) (Ref. 117894).
