PRODUCTION FUNCTION ANALYSIS IN AQUACULTURE

        

In carp culture, the quantity of fish farmed and harvested represents the outputs for which various inputs are used.  The production function is as follows:

Y= f (m, u, s, f, r, g, l)

Where,

Y = Output of farmed carps kg/ha

m = cattle manures in kg/ha

u = urea in kg/ha

s = superphosphate in kg/ha

f  = stocking density in no./ha

r = ricebran in kg/ha

g=groundnut oil cake in kg/ha

l = labour in man-days.

The above equation could be solved with required data set in a computer using some analytical software such as SPSS.  Some researchers prefer to exclude pond area as an independent variable in the production function.  However, when ponds are classified according to area or volume then the variable area may be excluded.
