Title: FISH FERTILIZATION. 5. EFFECT OF ARTIFICIAL FEED ON THE GROWfH PERFORMANCE OF MAJOR CARPS
Abstract: The response of artificial feed (30%( crude protein) in major carps rearing pond has been studied. The results indicated the use of artificial feed in two ways: (i) direct utilization of feed, and (ii) indirect response of left over feed in terms of planktonic productivity. The planktonic biomass accounted for about 42% of the variations in fish yield. Correlation coefficients between increase in fish yield and planktonic productivity in both treated and control ponds were significant. Added nitrogen, in the form of crude protein, resulted in significant increase in wet weight, fork length, and total length of fish. However, increase in fish yield showed linear relationship with concomitant increase in water temperature. The maximum benefit from artificial feed was derived by Cirrhina mrigala followed by Labeo rohita and Calla calla.
