Year 1

  1. Characterize growth of juvenile red pacu under monoculture conditions encountered on Maui utilizing locally available commercial feeds.
  2. Compare growth and survival in monoculture and polyculture (e.g., Chinese catfish and red pacu) growout trials on Oahu.
  3. Initiate the establishment of broodstock populations for red pacu on three islands.
  4. Obtain and collate technical information available on pacu including those written in foreign languages.
  5. Locate sources of the black pacu that meet import requirements for the state of Hawaii.
  6. Conduct technology transfer to appropriate end users.

Year 2

  1. Conduct pilot-scale monoculture growout enterprises in collaboration with private sector farms.
  2. Characterize growth and survival of juvenile red pacu in closed recirculating systems.
  3. Test market pacu as a food fish species on both Oahu and Maui and conduct survey of ornamental market demand.
  4. Technology transfer to appropriate end users.
