Abstract
Previous research showed that stocking 1.5 rohu (Labeo rohita) and 0.5 common carp (Cyprinus carpio) m¿2 yields the highest production in small holder ponds in Bangladesh. The present study looked into the effects of additional stocking of Nile tilapia (Oreochromis nilotica) in fed or non-fed ponds on water quality and fish production. A low, additional stocking density of 0.2¿Nile¿tilapia¿m¿2 was tested. All treatments were executed in triplicate in 100¿m2 ponds and the duration of the experiment was 4.5 months. The results showed that tilapia addition increased nutrient concentrations and reduced total suspended solid concentration and phytoplankton biomass (P
