The study investigated the potential for increasing carp (<italic>Cyprinus carpio </italic>L.) production in temperate climates without expanding farming area and simultaneously reducing wastewater discharge in intensive fish production using an in-pond cage system. An earthen pond with a stocking density of 209.3 kg per ha−1 and four cages stocked with 8.12 kg m−2 (A1 and A2) and 2.61 kg m−2 (B1 and B2) were monitored. The gross yield from the cages was 27.09 kg m−2 (A1), 24.3 kg m−2 (A2), 10.09 kg m−2 (B1), and 9.73 kg m−2 (B2). The fish in the pond had the highest specific growth rate (SGR) at 0.98%, and the feed conversion ratio (FCR) was above 3 for all the cages. The cages provided a high enough nutrient load to enable a net fish production of about 450 kg ha−1 in the pond. Ineffective feed utilization affected the production performance in the cages. Thanks to the high yield obtained in the pond, the overall return on the investment was 16%, which rendered production profitable.
