Technical Guide for Tilapia Farming (CDI, 1998, 51 p.)


Complete and detailed information on the state of aquaculture and fisheries in the country concerned by the study is necessary. The study should show:

  • A brief description of the history of these activities, in the country describing successes and failures and analysing the causes for their incidence.
  • The actual situation of both the aquaculture and the fisheries sectors (industrial and artisanal); annual production, species, markets, imports, exports etc..
  • An outlook and forecast for these sectors.

Moreover, it is necessary to answer the following questions:

A. Technical information

  1. Fish Species
    • Which are the endemic fish species?
    • Which are the targeted species for fish farming, species that are already farmed in the region and the possibilities of supply for fry and/or broodstock?
  2. Potential Sites
    1. Land
      • What is the soil composition?
      • What is the nature of vegetal cover?
      • Establish the site topography (particular for drainage and flood risk)
    2. Water
      • Measurements required:
        • Water quality; both physical analysis (temperature graph, conductivity) and chemical analysis (pH, nitrite, ammonia, etc) are essential.
        • Water volumes available (annual graph, m3/sec. etc.) Water supply by gravity, pumping? Seasonal variation?
      • National legislation, Riparian Law?
      • What is the human or industrial activity upstream and downstream?
    3. Geographical situation
      • Site description (localisation on map, altitude, etc.)
      • Road networks (+ railways).
    4. Climate
      • What is the type of climate, temperatures and monthly/annual rainfall?

B. Economic information

  1. Markets
    1. Local markets:
      • Types of product consumed and requested/desired?
      • Quantification of the market by product?
      • Estimation or records of product values (ex-farm, wholesale, and retail)?
      • Evaluation of competition (local producers, imports, fisheries)?
    2. Export markets:
      • What is the actual situation?
      • What is the export potential?
  2. Potential in fish feed supplies
    • Are there any fish or animal feed processing factories?
    • Appraisal of the interest and motivation of the existing factories to produce fish feeds?
    • What are the raw materials available for the manufacture of fish feeds?
    • Estimation of formulated feeds costs and raw material costs?
  3. Civil engineering, construction
    • What are the possibilities for
      • Earth works?
      • Construction (concrete, buildings etc)?
      • Supply of requisite materials (Cement, PVC pipes, etc.)?
  4. Labour
    • What is the availability and cost of labour and personnel (workers, employees, management)? #*Documentation on social regulations, employees rights and company obligations.
  5. Services
    1. Electricity:
    • Has the site accessibility to supply and what is the cost of electricity?
    • Appraisal of electricity supply security?
    1. Transport:
    • Possibility and cost for transport of goods (including refrigerated transport); roads, railways, air.
    1. Fuel:
    • Availability and cost of different fuels (diesel, petrol, and gas.)?
    1. Telecommunications, post, banks, insurance and different services.
    • Availability and cost?
    1. Repairs & maintenance
      • Service stations, mechanical engineering, electricians, etc.
  6. Current economical situation
    1. Inflation - average rates and forecasts.
    2. Interest rates (overdraft - short, medium and long term loans) applied by local banks.
    3. Currency stability towards reference currencies (US$ and Deutschmark).
    4. Potential for access to local and international financial assistance programmes or investment incentive schemes

C. Information on legislation

  1. Company registration
    • Collect all useful information on this topic.
  2. Exploitation/Operating permits
    • Which are the local administrative offices concerned and what are the permits required for construction and operation?
    • What is the legislation concerning the import and production of exotic species?
  3. Immigration
    • What are the conditions for expatriate personnel regarding residence and work permits?
  4. Taxes

Collect documentation on custom duties (equipment imports), personal and corporate taxation. Taxes on vehicles, boats, service use etc.
