Abstract

Female and male brooders were vaccinated by intraperitoneal injection and intramuscular injection respectively. Unvaccinated brooders were used as control. Fry which was produced by vaccinated and unvaccinated brooders were reared separately in paddy field pond for 15 days for the first nursery rearing period and another 15 days for the second nursery rearing period. These field experiment conducted in four locations, namely slmean (2 location) and magelang (2 location). Results of these experiments indicated that brooders vaccination could increase survival rates of the first and the second nursery rearing periods approximately 65.00% and 3.69% respectively. Average weight and total length of fry which produced by vaccinated broodstock increased 12.59% and 58.51% during the first nursey rearing period, 8.55% and 7.14% during the second nursery period.

Abstract

In Indonesia, outbreak of MAS on cultured African catfish  occurs periodically. The outbreek seems relate closely to quality of fry,. High quality fry and proper handling will ensure the successful of African catfish culture. Vaccination on vrooders is one of methods to produce high quality of African catfish fry. The objectives of this experiment  were to know effect of fingerling produced by vaccination brooders on survival., growth rate, and fish production  during grow out periode. Female and male brooders were vaccinated by intraperitoneal and intramuscular injection of 0.5 ml vaccine respectively. Unvaccinated brooders were used as control. Those brooders were spawned 2-4 weeks after vaccination. Fry which produced by unvaccinated brooders was reared separately in paddy field pond 15 days for the first nursery rearing. Fingerling produced by the second nursery rearing period was used for grow out for 3 mounths. Results of this experiment indicated that brooders vaccination could increase survival rate and production of African catfish approximately 22.16% and 9.94% from control respectively. However, the length and weight of fingerling produced by vaccinated brooders were lower than fingerling produced by unvaccinated brooders
