      Nursery and grow-out operation and management of milkfish 

      I Bombeo-Tuburan & DD Gerochi - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      This paper reviews the results of studies on the pond culture of milkfish Chanos chanos Forsskal at the SEAFDEC Leganes Brackishwater Station, Leganes, Iloilo since its establishment in 1973. Substantial contribution on the nursery system includes increased stocking density and survival through the use of nylon substrates, supplemental feeding with rice bran, the use of hatchery-reared and stunted fingerlings as alternative sources of stocks, and improvements in the acclimation process. Studies on monoculture and polyculture in grow-out ponds investigated the use of stunted fingerlings, kitchen or algal nursery ponds, stock manipulation techniques, increased stocking density using the plankton method, method frequency and quantity of fertilization, modular pond culture system, and initial findings on fish diseases. Constraints setting back increased production in the Philippines are discussed.

      Nursery and grow-out operation and management of Penaeus monodon (Fabricius) 

      KG Corre - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      The results of research on nursery and grow-out rearing of prawn conducted by the SEAFDEC Aquaculture Department for over a decade are reviewed. Different rearing facilities designed to accommodate hatchery-produced prawn fry are presented with corresponding data on growth, survival and production. Studies on stocking density, fertilization/natural food production, water management, feeds and feeding schemes and harvest/post-harvest handling are evaluated and viable technology identified. Diseases, pests and predators and other factors considered as production constraints are also mentioned.

      The success in hatchery operation for prawn coupled by the gradual emergence of nursery and grow-out rearing technology have triggered off a technology-dependent prawn industry. When SEAFDEC AQD was established in 1973, there were very few commercial prawn monoculture ventures in the country. Prawn pond production was mostly an incidental crop in milkfish culture. At present, various prawn grow-out techniques ranging from extensive, semi-intensive and intensive culture systems are in practice. SEAFDEC AQD focused its research on the extensive and semi-intensive culture systems which are within the reach of most farmers in contrast to the intensive system that is highly capital-intensive.

      There have been much work done in nursery and grow-out operations, but much remains to be done in research, among which are the development of nutritionally-efficient and low-cost feed, control of diseases, etc.

      Nursery and grow-out operation for tilapia and carp 

      MH Carlos & CB Santiago - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Most researches conducted at the Binangonan Freshwater Station of the SEAFDEC Aquaculture Department were directed toward enhancing growth and survival of the young tilapia and carp in the nursery as well as increasing yields in grow-out cages, pens, and ponds. Studies included the culture and evaluation of phytoplankton and zooplankton as feeds of the tilapia and carp fry to fingerlings; determination of protein and amino acid requirements of young Nile tilapia; development of practical dry diets; evaluation of feeding regimes, feeding rates, and feeding frequencies ; and the use of fertilizers in nursery ponds.

      For the grow-out aspect, one of the earliest studies demonstrated the profitability of the monoculture of tilapia in cages which triggered the initial proliferation of tilapia cage culture by the private sector in areas near the Station. Subsequently, supplemental feeds were developed and evaluated; non-conventional feedstuffs were tested as feeds or feed components; and the growth rates of Nile tilapia fingerlings in cages at varying stocking densities were evaluated at three distinct rearing periods covering one year.

      Prior to the successful mass production of bighead carp fingerlings at the Station, studies on polyculture of tilapia, milk fish, and different species of carp were conducted in cages and pens with remarkable results. This led to the technology-verification projects on polyculture at various areas in Laguna Lake. With the availability of freshwater fishponds for research purposes, studies on polyculture in ponds were also conducted.

      The Philippine aquaculture industry 

      AS Camacho & N Macalincag-Lagua - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      The aquaculture sector of the Philippine fishing industry registered the highest growth rate of 12.5% in 1977-1986. The contribution of aquaculture to the total fish production was equivalent to 24% in 1986 compared to only 85 in the early 1970's. In terms of quantity, the mariculture subsector registered the highest growth rate of 10.2% in 1982-1986, whereas in terms of value the brackishwater fishpond subsector showed the highest growth rate of 33%. Meanwhile, freshwater aquaculture production exhibited a negative growth rate due to reduction of activities in Laguna de Bay and the slow expansion in hectarage of the commercial freshwater fishponds.

      Research by several agencies concentrated heavily on the culture of milkfish (Chanos chanos), tilapia (Oreochromis niloticus), Chinese carps (Aristichthys nobilis and Hypophthalmichthys molitrix), tiger prawn (Penaeus monodon), and sea bass (Lates calcarifer). Innovations in seaweed, oyster, and mussel farming are also discussed.

      Research directions are presented to assure an ecologically sustainable growth in aquaculture with emphasis on countryside development.

      Summary of workshop recommendations 

      JV Juario & LV Benitez (Eds.) - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      A special workshop among participants was conducted to assess the status of the aquaculture industry in Southeast Asia, particularly in Malaysia, Philippines, Singapore, and Thailand. Although hatchery, nursery, and grow-out culture techniques had already been developed for most of the economically important species cultured in Southeast Asia, the outcome of the workshop showed that there are still major constraints to be able to increase production. Further studies have to be conducted to have greater control of factors that lead to better production. The participants prioritized the economically important species and the research area for each species for the Region.

      Training programs of SEAFDEC Aquaculture Department 

      J Honculada-Primavera - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development Center
      With training as one of its three mandated functions, the SEAFDEC Aquaculture Department offered its first training course in 1974. Since then it has trained some 6 519 participants in various degree and non-degree programs. The degree courses are MS. Fisheries (Aquaculture) and M. Aquaculture in collaboration with the University of the Philippines in the Visayas.

      The non-degree programs include regular short-term courses, onsite seminars internship training and practicum for graduating students. The "hands-on" short-term courses cover Prawn Hatchery and Nursery, Marine Finfish Hatchery, Brackishwater Pond Culture, Sanitation and Culture of Bivalves, Freshwater Aquaculture, Aquaculture Management, Aquaculture Engineering, and Aquaculture for Social Scientists. A profile of 637 1982-1986 training participants show 82.3% from Southeast Asia, 79% male and 57.5% from government sector.

      The paper discusses planning and implementation of training programs, funding support (Japanese Government, International Development Research Centre of Canada, FAO Network of Aquaculture Centres in Asia), and future trends.
