Biologie     Verklarende woordenlijst (bv. epibenthic)

Obligate air-breathing (Ref. 126274); Found in hill streams to lowland wetlands (Ref. 57235) often occurring in ephemeral waters (Ref. 44894). Adults are found in medium to large rivers, flooded fields and stagnant waters including sluggish flowing canals (Ref. 12975, 12693), in streamlets and estuaries (Ref. 41236). Benthic (Ref. 58302), burrowing in moist earth in dry season surviving for long periods without water (Ref 2686). Occasionally dug out in old taro fields, in Hawaii, long after the field has been drained; more frequently observed in stream clearing operations using heavy equipment to remove large amounts of silt and vegetation where the eels are hidden (Ref. 44091). Nocturnal predators devouring fishes, worms, crustaceans, and other small aquatic animals (Ref. 44091); also feed on detritus. Are protandrous hermaphrodites. The male guards and builds nest or burrow (Ref. 205). Marketed fresh and can be kept alive for long periods of time as long as the skin is kept moist (Ref. 12693). Good flesh (Ref. 2686). Important fisheries throughout Southeast Asia (Ref. 57235).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Male builds a large free-floating bubblenest among the submerged vegetation close to the shoreline; eggs are spat into the nest after being laid; male guards the nest and continues to guard the young after hatching till they are on their own (Ref. 44091). Spawning occurs in shallow water (Ref. 2060). Sex reversal is completed in 8-30 weeks (Ref. 34260).
