    Abstract: This study analyzed the economics of small-scale catfish farming 
  in Ido local government area of Oyo State. Sixty small-scale catfish farmers 
  were selected using simple random sampling technique. Structured interview schedule 
  was used to collect information from the respondents. Descriptive analysis revealed 
  that the average age of respondents was 45.07 years. Average year of schooling 
  was 9.5 years and 90% of them use earthen ponds. The major problems faced by 
  the catfish farmers were predators, high cost of inputs and finance. Per harvest 
  cost and returns analysis revealed the gross margin as <img src="http://medwelljournals.com/fulltext/aj/2010/images/img10-2k10-318-321.gif" width="14" height="13" align="absmiddle">428, 
  917.78, net revenue as <img src="http://medwelljournals.com/fulltext/aj/2010/images/img10-2k10-318-321.gif" width="14" height="13" align="absmiddle">370,154.40 
  and the Benefit Cost Ratio (BCR) as 2.173. This result shows that catfish farming 
  is a profitable enterprise. Regression analysis was employed to determine the 
  relationship between cost of production and returns. Adjusted R<SUP>2</SUP> 
  of 89.6% revealed that rent on land, pond construction cost, cost of fingerlings, 
  feed cost, transportation as well as salary and wages were significant factors 
  affecting total revenue of respondents.
