Producing hybrid fry from cross-breeding between Barbus xanthopterus

Abstract

The process of hybridization was carried out between female of Barbus xanthopterus X male of Barbus sharpeyi by artificial reproduction in Marine Science Center hatchery. Environmental factors (Temperature, salinity, dissolved oxygen, and pH) of the hatchery water were measured. The environmental factors within the optimum limits for the process of artificial breeding of these two species. The fertilized eggs were hatched and the larvae were reared inside the hatchery for six days. Later the hybrid larvae transferred to floating cages in the earthen pond, the initial larval weight was5.2 mg. The rearing of hybrid larvae continued for 20 days and the average of final length was 20 mmand average of final weight was 41mg.
