Analyze and compile the nutritional composition of potential feed ingredient resources in American Samoa into a feed manual for use in developing formulated aquaculture feeds…

The overall objective is to develop an aquaculture feed manual containing the nutritional value of animal and plant products and byproducts available locally in American Samoa, basal formulas for omnivorous and carnivorous finfish feeds using these locally available feed ingredients, and basic feed processing techniques for American Samoa.

The specific objectives are to:

  1. Identify, quantify and collect potential local products and byproducts for aquatic feeds development in American Samoa and dry samples for shipment to the Oceanic Institute (OI) for compositional analysis.
  2. Analyze the nutrient composition of selected samples. Analyses will include: proximate composition (crude protein, crude fat, ash, moisture, and fiber), gross energy, amino acids, and fatty acids, when applicable. Data on ingredients will be compiled in a database.
  3. Compile a feed manual containing the following information: a) list of locally available ingredients and byproducts, and their nutritional composition; b) practical finfish feed formulations using local  ingredients; and, c) feed processing techniques and quality control tests (mix time for mixers, ingredient particle size determinations, pellet stability test) for use in making aquaculture feeds containing the identified ingredients.
  4. Transfer of technology and dissemination of information will be achieved through a work shop and feed manual hand-outs to local producers and farmers.

Aquaculture of Opihi…

 The overall objective is to develop a suitable feed for Opihi.

The specific objectives are to:

Year 1

  1. Collect wild giant opihi and establish a broodstock holding facility.
  2. Develop an artificial feed for opihi.
  3. Identify the best method of spawning opihi and develop larval rearing methods to increase survivorship.  Danger points include larval settlement and metamorphosis.

Year 2

  1. Continue testing feeds with adjusted nutritional profiles and with different attractants included to improve opihi growth.
  2. Rate the flavor of cultured opihi with a panel of experienced opihi eaters.
  3. Work on sustaining the life cycle in culture.  Focus on better management practices.  On land growout
  4. Transfer technology to a few motivated stakeholders via extensive, hands on extension and an industry manual summarizing the developed techniques for opihi aquaculture.
