      Competitive and comparative advantages of brackishwater aquaculture of tiger shrimp, mud crab, and milkfish in the Philippines in 1985-1995 

      LA Gonzales, CD Elca, VA Gonzales, PA Alviola IV, FJ Paraguas & C Olalo - In T Bagarinao (Ed.), Research Output of the Fisheries Sector Program, 2007 - Bureau of Agricultural Research, Department of Agriculture
      The brackishwater aquaculture sector contributes considerably to the growth of the fisheries sector. Tiger shrimp Penaeus monodon, mud crab Scylla serrata, and milkfish Chanos chanos, in particular are efficient users of domestic resources and earners of foreign exchange. These three commodity sectors have not been fully developed because of inadequate policies in research, technology generation, and extension, and in public investment and support services in production, marketing, and post-harvest processing. Our analysis used the domestic resource cost approach. The average resource cost ratios for the Philippines were 0.44 for tiger shrimp, 0.66 for mud crab, and 0.35 for milkfish. If the peso overvaluation is corrected, the comparative advantage can be dramatically enhanced with respective resource cost ratios of 0.36 and 0.55, and 0.28. Given the current international market and production technologies for these commodities, competitive and comparative advantage can be sustained above the breakeven border price per kilogram of US$6–7 for tiger shrimp, US$5–6 for mud crab, and about US$1 for milkfish. The actual border prices per kilogram during the past five years have been higher at US$12.34 for tiger shrimp, US$8.39 for mud crab, and US$2.39 for milkfish. At current domestic costs and border prices of the these commodities, the advantage in exports may be sustained at yields per hectare greater than about 2 mt tiger shrimp, 100 kg mud crabs, and 500 kg milkfish. To enhance the efficiency of production of these commodities, the following areas of intervention are needed:
      • Technology improvements in seed production from the hatchery of tiger shrimp, mud crab, and milkfish
      • Research and technologies for diagnosis, prevention, and control of diseases of tiger shrimp (e.g. luminous bacteria)
      • Training in farm management to enhance the skills of small-scale pond operators
      • Public investments in infrastructures and support services including credit access to enhance efficient flow of goods and services from the farm to strategic market outlets
      • Market development to ensure sustainable outlets for brackishwater pond production
      • Reforms in trade and exchange rate policies to enhance global competitiveness

      Milkfish grow-out culture in ponds 

      N Sumagaysay-Chavoso - SEAFDEC Asian Aquaculture, 2003 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Milkfish farming is regarded as the backbone of Philippine aquaculture. In 2001, nearly 50% of the Philippines' aquaculture production was milkfish cultured from brackishwater ponds. It has 3 major culture systems: extensive; semi-intensive and intensive. A brief outline is given of the stocking and feeding procedures, providing also some details as to investment costs and returns.

      Price relationships in Philippine milkfish markets: Univariate and causality analysis 

      ND Salayo - Aquaculture Economics and Management, 2006 - International Association of Aquaculture Economics and Management (IAAEM)
      Uncertainties and lack of information on milkfish product prices, along with production-related problems with inputs, generally constrain efficient resource use in milkfish grow-out operations. Milkfish growers complain of fluctuating product prices such that when output price is low, they refrain from investing in inputs and technologies recommended to boosts production. The industry wants to know the state and behavior of milkfish prices. ARIMA models showed instantaneous price relationships between monthly wholesale prices in Manila and the regional producing areas. The cross-correlations of the error terms of the ARIMA models showed that prices in Manila are related with Lucena, Dagupan, Iloilo, and Zamboanga prices, but not with Cebu. Seasonal price indexes are higher (> 1) from December to May and lower (< 1) from June to November. Milkfish grow-out operators may benefit from understanding these patterns of price movements.
