This conference aimed to consolidate all existing data on milkfish, plan the directions and magnitude of future research related to milkfish and develop a collaborative program on milkfish research among countries, research institutions and other organizations. Milkfish, which is widely distributed throughout the Indo-Pacific and South China Region, is considered an important food fish, and extensive culture is currently being done in Indonesia, Philippines and Taiwan. One of the major problems of the industry is the inadequacy of fry supply. Milkfish fry are caught in the wild and the wide fluc­ on January 17, 2019 at 11:19 AM CST tuations as to amount and seasonal occurrence have hampered rational planning and investment for the development of the industry. This conference, therefore, is significant. The solution to the fry supply problem would contribute immensely to the development of the milkfish industry, and consequently contribute to the protein requirements of a burgeoning population in the region, and also may become an export commodity, thereby increasing the foreign exchange of the countries http://repository.seafdec.org.ph of the region. Working papers were requested from the participants which formed the bases of the discussions in the sessions. Six sessions were organized to determine the existing knowledge and information on milkfish, identify the knowledge gaps and determine the priorities and strategies to bridge these gaps. Downloaded by [Anonymous] from Session I discussed the behavior and bio-ecology of milkfish in the wild; Session II, egg and larval surveys; Session III, maturation and reproduction in the wild and captive fish; Session IV, egg incubation and larval rearing; Session V, predators, diseases and physiology of s stress, and Session VI, research network for countries and institutions engaged in milkfish research. The conference agreed on the following highest priorities and the countries/institutions which will implement them: (1) physiological maturation/induced breeding (Taiwan, SEAFDEC, Oceanic Institute); (2) racial studies (a) morphology (Japan), (b) biochemical (Oceanic Institute and Hawaii Institute of Marine Biology); (3) larval rearing ii (Taiwan, SEAFDEC, BFAR, UP, Hawaii Institute of Marine Biology, Oceanic Institute, India and Indonesia); (4) migratory and spawning studies (SEAFDEC, Oceanic Institute and Thailand); (5) reference repository (SEAFDEC); (6) sex determination (SEAFDEC); (7) cryo­ genics for males (Taiwan, SEAFDEC); (8) pituitary bank (SEAFDEC); (9) egg and larval survey (SEAFDEC, UP, BFAR, India and Indonesia). Capsulated research proposals by the representatives of the different countries/institutions, in attendance, were submitted. The proposals included objectives, methodology, institutions involved, approximate cost and personnel requirements. on January 17, 2019 at 11:19 AM CST http://repository.seafdec.org.ph Downloaded by [Anonymous] from INTERNATIONAL MILKFISH WORKSHOP-CONFERENCE Tigbauan, Iloilo, Philippines May 19-22, 1976 Sponsored by the Aquaculture Department of the
