Kayendedwe ka moyo wa Kanthanga nyanja

Development wa Kanthanga nyanja tichipeza magawo zotsatirazi: dzira, larva, nsomba zazinkhanira wamkulu. Mphutsi akutulukira pa mazira tiwolokere momasuka ndi magawo awiri: nauplius ndi Zypries. Mitundu ozizira madzi a siteji larval chimakhala cha masabata 2 pamaso loyamba la mweziwo, pamene otentha - za 3-5 masiku.
