Abstract
Data on the production of prawns (Macrobrachium rosenbergii) from ponds are not suitable for traditional analysis of variance models because the determining variables or treatments are at widely varying levels. However, the data are amenable to analysis within a simple two‐equation econometric model which is recursive in structure. The first equation has survival rate as a function of dissolved oxygen levels, pH measurements, stocking density, and length of grow‐out period. The second equation has kilograms harvested per hectare as a function of survival rate, stocking size, stocking density, length of grow‐out period and kilograms of feed. The explanatory power of both equations was very promising: R2, the square of the multiple correlation coefficient, was 0.99 for the first equation and 0.97 for the second equation.This publication has 1 reference indexed in Scilit:
