Description of life cycle and mating behavior | Oviparous (Ref. 265). A female turns to her side, deposits her eggs on the bottom and resumes an upright posture. This procedure is repeated until all eggs have been laid, which may take several days (Ref. 11548). As eggs are being deposited, males are releasing milt, fertilizing the eggs (Ref. 27547). There is no observable pairing of the sexes; the whole spawning area is white with milt (Ref. 11558). |
