生活サイクルと交尾行動の説明 | Migrates some tens of km to spawning sites, which are often located in tribbutaries. Males form large aggregations, each male defending a small territory. Females spawn only once a year and in some populations, during a very short period of 3-5 days. Females lay sticky eggs into excavations made in gravel (Ref. 59043). |
