Samples of each treatment 20 fish carp with 4 treatments. Treatment I (wastewater new households by ferns), treatment of II (wastewater new households by plants hyacinth), Treatment III (domestic wastewater long by ferns), treatment IV (household wastewater long by water hyacinth plants). The measured parameters ie width, length and weight of carp within a certain period. Data were analyzed using Analysis of Variance (ANOVA) two lanes and qualitative analysis. The results obtained by analysis of existing water plants on the effect of domestic wastewater on growth of carp (Osphronemus gouramy), as well as the provision of fern (Azolla pinnata) provides the most good influence on the growth of carp.
