| Description of life cycle and mating behavior | Males construct foam nests and guard the growing larvae until mid-January when the first seasonal rains flood the breeding area, causing the about 10 cm long young eels to disperse (Ref. 40645). Males outnumber females (3:1) and are considerably larger than females (Ref. 40645). There are three successive batches of eggs deposited in a spawning period. Not all eels with fully developed gonads (in Goiapi drainnage) participated in the annual spawning activity suggesting that mating success depends in part on finding suitable breeding sites (Ref. 40645). |
