Liguasan Marsh is in south-central Mindanao, Philippines and it is the largest swamp and marsh area in the island. The marsh is an important wetland site and supports breeding populations of many fishes, waterbird species, including herons and egrets, rails, shorebirds, ducks and crustaceans such as shrimps including giant freshwater shrimps. As per observation in the marsh area, plenty of giant freshwater shrimps from wild that found in every landing sites and source of the largest size. The giant freshwater prawn (Macrobrachium rosenbergii) is considered to be the world’s largest shrimp and a high value species. The culture of freshwater prawn in the Philippines started in 1970s. Culture trial ensued, but technology was not sustained at the commercial level due to necessity in broodstock development and seed improvement. A study will be conducted to assess the population, determine the reproductive performance and offspring quality of Macrobrachium rosenbergii broodstock from Liguasan Marsh, Philippines. The population assessment will be conducted in randomly selected landing sites of the marsh area. A trials on captive breeding will be conducted. Ovarian development, moulting and spawning events will be checked during the period of study. In addition, a number of egg and larval quality parameters will be determined. The breeding frequency, fecundity, egg laying success rate, egg dimensions and egg hatchability will be also determined to assess the potential of wild caught adult M. rosenbergii in Liguasan Marsh for captive breeding and for hatchery production. In general, wild broodstock from different landing sites of the marsh will be determined for its offspring quality. The results of the research will be the source of the broodstock for future attention in hatchery operations of Macrobrachium rosenbergii from Liguasan Marsh, Philippines. The results will be the basis for selective breeding research in Southern Philippines to improve the local culture environment for freshwater prawn.
