In recentyears, fishfarminghasundergonesuccessivetransformations, consolidatingitself as animportantactivity in national agribusiness. Highlightingmainlytilapiafarming, anexoticspecies, whichpresentsgoodadaptability, withfastgrowth, high productivityandwith a definedtechnologicalpackage. Despitetheprogressivegrowthoffishfarming, littleimportancehasbeengiventotheeconomicaspectoftheactivity in some regions. Then, theemergingneedarosetobetterunderstandtheeconomicaspectsoftilapiafarming, in additiontoidentifyingthemostrelevantitems in thecompositionoftheproductioncostandthemainparametersthatinfluence its profitability. The productioncostisoneofthemostimportantinformation for anyproductiveactivity, it wouldnotbedifferent for fishfarming. It ismainlycomposedoffeedexpenses, whichcanreach 80% ofthe total productioncost, beingthemainfactorofproductionandoneofthemainobstaclestotheactivity. Thus, food management isofparamountimportancetoobtainbetterresultsoffeedconversionandincrease in weightgain, determiningbetterzootechnical indexes, whichwilldirectly interfere in economicresults. Thisworkaimedtoanalyzethecostsandtheeconomicand financial viability in theproductionofNiletilapia in differentrearing systems in properties in theStateof Rio de Janeiro. Data from 10 propertiesofdifferentsizes, structuresandproduction volume wereevaluated, thusallowing a betterestimateandunderstandingoftheeconomicandzootechnical reality offishfarming in theStateof Rio de Janeiro. The averageproductioncostwas R $ 4.51 / kg oflivefish. Feedwasthe input thatmostinfluencedthisresult, accounting for 66.21% ofproductioncosts. Accompaniedby 11.49% ofexpenditureon labor. The averagevalueof Payback foundwas 0.65 years. Net PresentValue, ontheotherhand, presentedanaverageresultof R $ 161,161.35 at a minimumattractiveness rate of 10% per year, for 10 years. WithanInternal Rate ofReturnof 188%. Fromtheresultsfound for costanalysis, zootechnical indexes andthe financial viabilityofNiletilapiafishfarms in the South Fluminense region it wasfoundthattheproductionofthisfishbythestudiedproducersisprofitable.
