B. Project Objectives

General Objectives

To increase fish production through silver pompano and rabbit fish farming in Tanzania and Kenya marine waters.

Specific Objectives

  1. To breed and produce seeds for silver pompano and rabbit fish under hatchery conditions.
  2. To examine growth performance of silver pompano and rabbit fish fed on different feed diets and stocked at different densities.
  3. iii. To evaluate the cost of farming silver pompano and rabbit fish in comparison to other cultured species and impact on community livelihoods.
C. Expected Results
  • Increased knowledge and number of fingerlings produced for marine species.
  • Increase in number of mariculture farmers doing cage and pond culture of high value marine fish species.
  • Increased production and income from high value marine fish species.
D. Project Activities
  • Breeding of silver pompano and rabbit fish in laboratory.
  • Larval rearing of the two species in laboratory.
  • Conduct growth performance and optimum stocking density of the two culture species.
  • Undertake cost analysis of farming the two species and impact on community livelihoods.
