  2. Malnutrition in East Africa • (Excluding GDP’s greater than 4 trillion USD) • In descending order of Protein Consumption- • Kenya (59.7g) • Somalia (52g) • Tanzania (49.1) • Mozambique (38.6)

  3. (Food and Agriculture Organization)

  4. Shellfish Farming Factors • Depth • Temperature • Road access/proximity to market • Salinity • Nutrients (and the related presence of filterable food sources) • Turbidity • Substrate • Current Strength

  5. Depth • 3 fathoms (18 ft.) or less • Adjacent to the • Excluding mangrove stands (FAO Africover.org) • Noting marine protected areas

  6. Total Suitable Area 4126.7 km2 of sea floor of which the vast majority is at least partially sheltered by reefs or the topography of the shore (Office of Geographer, BIR, 1981) + 500 km2 salt flats (theseaaroundus.org Pew Foundation)

  7. Factors that help determine marine nutrient levels: • Human waste • Run-off • Upwelling • Thermocline mixing Marine Primary Productivity

  12. If primary production were the only limiting variable in shellfish carrying capacity…

  13. Summary • Tanzania’s traditional fisheries are depleted • There is space and need for shellfish protein • The availability of filterable food sources for extensive aquaculture is not a limiting factor

  15. Market Value • At $1.00 - 2.00 (USD) per kg in local markets, (and potencially greater values at tourism hubs) shellfish meat sells at roughly $1,000-$2,000 per tonne. • With the potencial for 10.9 tonnes/km*yrof shellfish meat and 1,424 km of coastline…
