Abstract:
The effects of introducing common carp (CC) and of adding artificial feed to fertilized rohu ponds on water quality and nutrient accumulation efficiency were studied. All ponds were stocked with 15 000 rohu ha-1. Treatments included ponds with rohu alone, rohu plus 5000 common carp ha -1 and rohu plus 10 000 CC ha-1. A comparison was also made between supplementally fed and non-fed ponds. The overall highest nitrogen (N) and phosphorus (P) concentrations were observed in ponds with 5000 CC ha-1, followed by ponds with 10 000 and 0 CC ha-1. The largest fractions of N and P inputs accumulating in fish, phytoplankton and zooplankton were observed in ponds with 5000 CC ha-1, followed by ponds with 10 000 CC ha-1 and subsequently ponds without CC. Relatively more nutrients accumulated in benthic organisms in ponds without than in ponds with CC. A smaller fraction of the nutrient input was retained in fish, plankton and benthic organisms in ponds without CC compared with ponds with CC. Compared with 5000 CC ha-1, stocking 10 000 CC ha -1 can be considered as overstocking, because this leads to lower fish production and relatively less nutrients retained in plankton and benthic organisms. © 2008 Blackwell Publishing Ltd.
