Determination of Artificial Incubation Time of Some Malawi Cichlid Species Incubating in the Mouth (Iodotropheus sprengerae, Cyrtocara moorii, Maylandia estherae, Labidochromis caeruleus) Eggs
Journal Title: Acta Natura et Scientia - Year 2020, Vol 1, Issue 1
Abstract
Malawi cichlid species belonging to the Cichlidae family are among the most popular commercial species in the aquarium industry. Females of this species begin to incubate their eggs in the mouth after ovulation. Professional producers continue to induce vomiting of the eggs from the female's mouth at many different times and grow them with artificial incubation. The aim of this study is to determine the most appropriate time to induce vomiting and artificial incubation of eggs of these species. For this purpose, rusty cichlid (Iodotropheus sprengerae), blue dolphin cichlid (Cyrtocara moorii), red zebra cichlid (Maylandia estherae) and electric yellow cichlid (Labidochromis caeruleus) were produced in colonies. The development of eggs and larvae obtained from broodstocks were observed. Critical times for cichlid culture have been determined. While electric yellow cichlid (L. caeruleus) completed its embryonic development on the 3rd day after ovulation, blue dolphin cichlid (C. moorii) and red zebra cichlid (M. estherae) species completed on the 4th day, rusty cichlid (I. sprengerae) completed on the 5th day. Therefore, the results of the present study revealed that it is not appropriate to apply the same incubation technique to all these species.
