Abstract
In this study we present the efforts of propagation of Bunnei in the Marine Science Center freshwater fish hatchery during of spring of 2006. The brooders weights ranged between 1.5-2.5 kg for females, and about 1 kg for male. The total dosage of pituitary gland was 4 mg/kg presented in two injections. The first was 10% of total dosage. The rest and second injection had given after 12 hours. Eggs 1350g in total weights were obtained after 12 hours from second injection. The males were injected with the first injection of 2mg/kg of PG extract. The fertilization rate reached 85%. The washing process was modified, it was for 20 min. only. The fertilized eggs were incubated in Zoug jars with a rate of 75-100 g/jar. High hatching percent (95%) were obtained with water temperatures of 24-25◦C. The hatching occurred after 72-76 hours. We obtained 750,000 larvae, incubated in the primary rearing incubators(tanks) over four days. They were fed with mixed eggs yolk. Then they were distributed to a closed system, an open system and outdoor ponds. The pesticide Actelic was used (1ppm) for the elimination of big zooplankton in the outdoor ponds before the release of the larvae. The feeding and growth were measured. It was found that Bunnei grow faster in outdoor earthen ponds
