A paste-form of soybean cake or other by-products from grain processing is applied from the 5th day after stocking, usually at a rate of 1.5-2.5 kg/100 000 fish daily. The stocking density is much reduced, compared to the rearing of yearlings. INU02, INU2, and MOS2 significantly improved relative weight gain, specific growth rate, protein efficiency ratio, and food conversion ratio of grass carp fed with food waste-based diet. FAO Names: En - Grass carp(=White amur), Fr - Carpe herbivore(=chinoise), Es - Carpa china View SIDP Species fact sheet. Nursery Earthen ponds (usually 0.1-0.2 ha and 1.5-2.0 m deep) are used for the nursing of grass carp. The feeding regime is similar but the rate is much higher. The total production from such systems can reach 8-10 tonnes/ha/yr. The marketing size for grass carp is 1-1.5 kg and 1.5-2.5 kg in ponds and cages respectively. Feeding rate should also be adjusted according to temperature and body size. Because of its utility as a biological control for aquatic vegetation, the grass carp has been legally introduced into at least 35 states in the US. Under culture conditions, grass carp can well accept artificial feed such as the by-products from grain processing, vegetable oil extraction meals, and pelleted feeds, in addition to aquatic weeds and terrestrial grasses. The royal family prohibited common carp to be sold and killed by the people. Careful planning of cage and pen culture developments inland water bodies, especially shallow lakes, is very important. If you have not witnessed this scene, big grass carp cruise the surface with their mouth open, literally vacuuming dozens of floating fish food … 0 %--Glucides. It is acceptable to consumers in many countries and it very likely has good potential for development. If populations are sufficiently high, grass carp tend to stimulate phytoplankton blooms that reduce water clarity. Aquatic plants are beneficial and a necessary part of lakes and reservoirs. They prefer relatively low fertility. Grass carp are especially good when smoked. Grass carp is an excellent model for studying vegetarian adaptation, as it shows food habit transition from carnivore to herbivore. Relatively larger (0.2-0.3 ha) and deeper earthen ponds are used for fingerling rearing. Culture techniques and models for pond, cage and pen culture have also been well developed. In terms of non-specific immune response, grass carp showed significant improvement in all three tested parameters (total serum immunoglobin, bactericidal activity, and anti-protease activity). In his review, Bain (1993) stated that Grass Carp have significantly altered the food web and trophic structure of aquatic systems by inducing changes in plant, invertebrate, and fish communities. The Central Institute of Freshwater Aquaculture (ICAR), Kausalyaganga, Bhubaneswar, 751002, Orissa, India. The initial feeding rate is 10-15 kg/10 000 fish daily and is gradually increased according to the demand of the fish. This usually means production costs are high.
