COMPARISON OF HUMIDITY CHAMBER, MARISOURCE HATCHING-TRAY AND ZUGER GLASS FUNNEL INCUBATION SYSTEMS FOR BREEDING OF CYPRINUS-CARPIO (L) AND CLARIAS-GARIEPINUS (BURCHELL)

Abstract

Humidity chamber, MariSource hatching-tray and ''Zuger'' glass funnel incubation systems were compared for hatching successes of both Cyprinus carpio and Clarias gariepinus fertilised eggs. The humidity chamber incubation system proved superior for C. carpio, whilst the MariSource hatching-tray system was better for C gariepinus. Fungal infections greatly influenced hatching results
