Abstract

 The aim of this study is to provide useful information about the population dynamics applied to carp cultivation for
maximum biomass production. In this report, the carrying capacity of common carp (Cyprinus carpio) grown on polyculture
system in earthen ponds (250m2 pond-area) with aeration and without aeration was investigated. Prior knowledge of pond surface area, fish species cultivated, inital and density population, survival rate, feed conversion, cultivaton time, and total fish production are some key variables required to estimate fish farming carrying capacity. Common carp when grown on aerated system, with density population of 1 fsh 2m2, has produced a maximum biomass yield of 183,772g (183.77Kg) achieved at the
peak of 27.8 months, suggesting that total fish harvesting in this period of time is highly recommended due to its maximum profitability.
