On the growth of grass carp, Ctenopharyngodon idella Val. in composite fish culture at Kalyani, West Bengal (India)

Experiments were conducted in eight ponds of 0.08 ha each for a period of 6 months to evaluate the production performance combinations of Indian major carps and exotic carps at varied stocking densities and species. The four different treatments evaluated were stocking densities of 5000 and 10 000 fingerlings/ha with three Indian major carps (catla, rohu, mrigal) and combination of three Indian major carps with three exotic carp species (silver carp, grass carp and common carp) in replicate ponds. The mean net production levels recorded in different treatments were 1791 kg/ha, 2385 kg/ha, 2532 kg/ha and 3472 kg/ha in 6 months in treatments with three species combinations at 5000/ha, six species at 5000/ha, three species at 10 000/ha and six species at 10 000/ha, respectively. Correspondingly, the mean growth, survival and feed conversion ratios recorded in four treatments were 432 g, 84.7% and 1.49; 567 g, 86.2% and 1.47; 318 g, 82.1% and 1.69; and 444 g, 80.4% and 1.67, respectively.

Asian aquaculture has been contributing in great measure to the global fish basket. The Indian subcontinent, with a rich biodiversity of fish species, has emerged as an important aquaculture country, particularly in the freshwater environment. Carps form the mainstay of culture practices in the country, supported by a strong traditional knowledge base and scientific input in various aspects of biology, environment, nutrition, and health management. New species and culture systems, integration with other farming systems, use of organic material as nutrient inputs, and depuration measures in waste-fed culture systems are being considered for enhancing aquaculture productivity. This article presents the status of grow-out production of carps in India and traces the growth of the practices over the decades as well as the potential of the sector.

“…Nevertheless, higher primary production levels stimulated by fertilization and reduced water flowthrough resulted in a greater abundance of natural food resources and provided more support for growth, especially of the filter-feeder fish species such as silver carp, bighead carp and tilapia. Also, grass carp under the modified pond management system showed a higher growth rate than under the traditional system, indicating a better feed base of natural food due to lower stocking densities (Sinha and Gupta 1975) and consumption of pelleted supplemental feed which was intended to feed common carp. All stocked species under the semi-intensive pond management system, such as the common carp, grass carp, silver carp, bighead carp and tilapia, showed significantly higher specific growth rates (in %), of 2.6 AE 0.2, 2.4 AE 0.3, 2.5 AE 0.1, 2.9 AE 0.2, and 3.4 AE 0.6 respectively, and when compared to those under the traditional management system, which were 1.8 AE 0.1, 1.9 AE 0.7, 1.7 AE 0.0, 2.0 AE 0.0, and 2.5 AE 0.4 respectively (Pucher et al 2010b).…”

“…Here, small amounts of green plants of comparatively high nutritional quality should be used to supplement the feed. Furthermore, grass carp stocked at low densities have shown extremely high growth rates in polyculture ponds, as investigated by Sinha and Gupta (1975).…”
