The objective of this research was to evaluate the effect of feed supplemented with baker’s yeast on survival rate of nile tilapia larvae and to determine the effective dose of baker’s yeast that could optimally improve larval quality.  The research was conducted at Pathology and Clinic of Fish Disease from June – September 2014.  Fish as brood stock candidates was cultivated at five concrete tanks (2x1x1 m3) at a density of 30 fish per tank.  Each tank was equipped with water inlet, outlet and water pump for recirculating and aerating.  After seven days of adaptation, fish was fed pellet supplemented with baker’s yeast at five different doses (0, 10, 20, 30, 40 g/kg food) for four consecutive weeks at 4%/bb/day, twice daily.  Larva was captured with seser and moved into five glass aquaria with density of 20 larvae/aquarium and reared for two weeks.  Data collected was survival rate of larvae achieved until the end of larval rearing.  Research result showed that larvae produced by brood stock fed food supplemented with 10 g baker’s yeast per kg food had the highest survival rate namely 60%.  As conclusion, supplementation of baker’s yeast into brood stock feed might increase survival rate of larvae.   Keywords:  nile tilapia, baker’s yeast, larvae, survival rate

Increase Survival Rate

Of 84 surgically treated cases of postcricoid carcinoma, 23 had a pharynxesophageal reconstruction by use of a laryngotracheal autograft. This procedure is most suitable in females with manifestations of the Paterson-Broun-Kelly syndrome. The distal esophagus is not “at risk” because of skip areas or second primary lesions. Failures are due predominantly to inability to control the lymphatic metastasis. Stomal recurrence may be due to ascending metastasis from the tracheoesophageal groove and mediastinum. A routine combined neck dissection is urged in all instances. Mediastinal node extirpation with or without resection of the manubrium may increase survival rate. Adequate surgical exposure with visualization, palpation, and exploration of the extent of the cancer is suggested prior to determination of the method of reconsruction of the pharyngoesophagus. In selected cases without previous radiotherapy the laryngotracheal autograft has proved satisfactory.

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
