Stocking Rate Estimations of Tilapia mossambica Fingerlings for some Inland Reservoirs of Sri Lanka
Authors:M. J. S. Wijeyaratne  H. H. Costa
Abstract:The Morphoedaphic Indices for several Sri Lanka inland water bodies (mostly ancient man-made reservoirs) were calculated using conductivity and depth data. The relationship between Morphoedaphic Index MEI and the annual catch of fish C was found to be equation image . Using this equation, the annual potential yields were calculated. The stocking densities of Tilapia fingerlings needed to be stocked were then estimated taking into consideration the natural recruitment of fingerlings from the already existing stocks of reproducing Tilapia.
Keywords:Morphoedaphic Index  fish catch  reservoirs of Sri Lanka  stocking density  annual potential yields
