Abstract

This study investigates the economic potential of five diffrent tilapia pond culture systems . Pond culture systems were based on the use of chemical fertilizer only (CHEM), feed only (Feed) , chemical fertilizer , chicken litter , and feed (TRAD) , chicken litter and feed with mixed sex or monosex stocking CLFEDMS and CLFEDSR , respectively . Data on inputs and outputs of each system were obtained from experiment conducted at the central Laboratory for Aquaculture Research (CLAR) . Data regarding labour requirements and equipments were obtained from the available information from the production ponds at CLAR Item costs for pond construction were obtained from the General organization for fisheries Resource Development . Budgets were developed for the five systems , utilizing 2.1 ha pond . Net returns , values of production for major inputs , break-even prices and yields , and average rate of returns to capital were estimated for each system. CLFEDSR ,TRAD , and CLFEDMS systems had the highest yield , net returms , and average rate of return to capital . The same systems had the highest margin betwwen average price and break-even prices to cover total cost which indicated reduced risk to farmers in the event of a decline in market price . The above systems had the highest net returns when production decreased by one or two standard errors . Sensitivity analysis indicated that TRAD and CLFEDSR systems maintained positive net returns if fish yield decreased by two standard errors and prices decreasd by 20% .
