Impact of stocking on yield in small reservoirs in Andhra Pradesh, India

Abstract

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.
