The relationships between surface area, stocking density and fish yield in 40 small reservoirs in India between 1994 and 1999 were examined. A significant positive correlation ( r = 0.6) was found between stocking density and fish yield. Area was negatively correlated with stocking density ( r = −0.57) and fish yield ( r = −0.62), but its correlation with efficiency of stocking was not significant for all the size groups of small reservoirs.
