Title StatementCarp polyculture in fertilized and unfertilized pond
General NoteMunoz, Nueva Ecija: CLSU, 1975. pp. 23-30. -(NSDB Assisted Proj. No. 7103 Ag; Inland Fisheries Proj
Summary, Etc.Three carp species of different feeding habits namely, Hypopthalmichthys molitrix (silver carp), Cyprinus carpio (common carp) and Labeo rohita (rohu carp) were combined in polyculture experiment to determine the effectiveness of fertilizer in raising carps. Chicken manure was broadcasted first in a single application of approximately 1100 kg/ha to provide an organic base to support productivity in the new ponds. The inorganic fertilizer, 16-20-0 or 0-20-0 with each application of approximately 50 kg/ha, was given when water visibility, as measured with a secchi disk, exceeded 45 cm. The fish grew most in the fertilized ponds and least in the unfertilized ponds. The addition of fertilizer in two previously unfertilized ponds starting on culture day 70, resulted in accelerated fish growth. The mean net productions in both treatments with fertilization were significantly higher (P<.05) than those without fertilization. Mean net production was 1080 kg/ha in ponds fertilized 14 days prior to stocking, 841 kg/ha in ponds fertilized 70 days after stocking, and 222 kg/ha in ponds without fertilization
