Abstract

Common carp is extensively domesticated globally. However, the existing common carp stock has disadvantages of early sexual maturation (< 6 months) and spawning in grow-out ponds at a small size. Hence, the genetic improvement of common carp made by the collaborative actions of the different institutions, which developed a superior Amur carp strain possessing an additional growth rate of 27.3 percent. The species is cultured, and its performance in Kerala was studied using a participatory approach. The study revealed that 30 days of rearing in natural freshwater ponds were required to rear Amur fry from its Spawn. The average fingerling size was 7.5 ±1.0 cm (2.0 ± 0.5g) after 45 days of rearing in nursery ponds. The survival percentage was 18,70 and 90 in the spawn, fry-to-fingerling, and grow-out stages, respectively. Stocking 10000 fingerlings per hectare can produce an average of 9.0 t of fish in 15 months. The production cost per hectare would be Rs. 7.9 lakh. Fifteen months of farming was required for this species to reach the marketable size of 1100 ±200 g.
