Conference paperZ Talib - In CT Villegas, MT Castaños & RB Lacierda (Eds.), Proceedings of the Aquaculture Workshop for SEAFDEC/AQD Training Alumni, 8-11 September 1992, Iloilo, Philippines, 1993 - Aquaculture Department, Southeast Asian Fisheries Development CenterIn aquaculture, nothing is more important than a well-balanced diet and adequate feeding. An undernourished fish is never able to maintain its health and attain its growth potential regardless of the quality of its environment. The production of nutritionally balanced diet for fish requires research, quality control, and biological evaluation. The Department of Fisheries first acknowledged the importance of formulated feed when it established the Feed Section at the Fisheries Research Institute in Glugor in 1976. With the establishment of the research branch, Brackishwater Aquaculture Research Centre (BARC), in Gelang Patah, Johor in 1979 and the National Prawn Fry Production and Research Centre (NAPFRE) in Pulau Sayak, Kedah in 1987, the feed section has been expanded further to cover pond grow-out feeds for fishes and shrimps and the postlarval stage of shrimps. The feed section in Glugor placed greater emphasis on larval and postlarval feed. In the case of freshwater fishes, research and production of feeds began in 1975 at the Freshwater Fish Research Station, Batu Berendam, Melaka. The development of formulated feeds is concentrated on fishes and crustaceans.
Evaluation of dietary freeze-dried Chaetoceros calcitrans supplementation to control Vibrio harveyi infection on Penaeus monodon juvenile Effects of supplementation of diets with freeze-dried Chaetoceros calcitrans to control Vibrio harveyi infection are evaluated through immune responses, and disease resistance of juvenile Penaeus monodon. Total lipid and fatty acid profile of Chaetoceros calcitrans is also analyzed. A challenge infection with 107 cfu/mL concentration of Vibrio harveyi is intramuscularly injected to juvenile Penaeus monodon after 45 days of feeding of diets supplemented with 15 g/kg and 30 g/kg dried Chaetoceros calcitrans. The use of dried Chaetoceros calcitrans is compared with that of ß-1,3 glucan Curdlan, a commercial immune enhancer. Incorporation of 30 g/kg Chaetoceros calcitrans in the diet enhances the immune system of shrimp as effected by high prophenoloxidase activity and plasma protein concentration and is better compared to the commercially available Curdlan. Chaetoceros calcitrans also contains polyunsaturated fatty acids (PUFAs) such as linolenic acid and eicosapentanoic acid (EPA) which are responsible for its antibacterial action against Vibrio harveyi. All these biological activities of Chaetoceros calcitrans add up to increase resistance of the juvenile Penaeus monodon to vibriosis as shown by its high survival rate from the challenge infection with Vibrio harveyi. Therefore, it is worthwhile to use Chaetoceros calcitrans as supplementary feed. Its effect in increasing the immune competence coupled with its antibacterial action, make the shrimp resistant to luminous vibriosis that continues to affect the industry, thereby augmenting aquaculture production.
Effect of feeding regimes on growth and survival of bighead carp (Aristichthys nobilis Richardson) fry CB Santiago & OS Reyes - In SS De Silva (Ed.), Fish Nutrition Research in Asia. Proceedings of the Third Asian Fish Nutrition Network Meeting, 1989 - Asian Fisheries SocietyTwo five-week feeding trials were undertaken to evaluate growth and survival of bighead carp (Aristichthys nobilis ) fry of 1.9-2.4 mg mean weight reared on various feeding regimes. In Treatment 1, the carp fry were fed with Brachionus alone. In Treatment 2, 3, 4 and 5, the fry were fed with Brachionus for 2, 4, 6 and 10 days, respectively, and then with an artificial diet for the remaining period. The carp fry were fed with the combination of Brachionus and artificial diet in Treatment 6 and with artificial diet alone in Treatment 7. Results showed that the combination of Brachionus and artificial diet was the best feeding regime in enhancing the growth of the bighead carp fry. Mean weights of the fry fed with Brachionus for 2, 4, 6 and 10 days prior to the shifting to artificial diet were similar to that of the fry fed with Brachionus alone or artificial diet alone. There was no distinct trend in survival as a function of feeding regime. However, Brachionus alone gave the highest survival rate in both trials.
