Figure 3. Schematic representation of the effects of common carp on nutrients (PO4-P, PO4-P, NO3-N, NO2-N, total ammonia nitrogen) and natural food availability. + and – indicate positive and negative effects, respectively. Filled ovals indicate processes and states that illustrate the influence of common carp on primary production.

Figure 4. Comparison of the effect of culture systems with common carp (CC) (polyculture of rohu and common carp) and without CC (monoculture of rohu) on nitrogen and phosphorus accumulation (%) in bottom soil and fish. Nitrogen and phosphorus retention efficiencies with no letters in common among three attached bars are significantly different (p < 0.05). Retention efficiency is calculated based on total input nutrients, higher total nutrient input and total fish (data from Rahman et al. Citation2008a).
