The stocking rate can be much higher (up to 20 000/ha) if cereals and pellets also used. The daily ration is approximately 3-5 percent of body weight. Common carp can be produced in extensive, natural food and supplementary feed-based monocultural production systems, in stagnant water ponds. Res., 6 (28): 2011, 6177-6182p. Can.

The tanks were stocked with European carp (initial weight 169 grams ± 56 grams) from a commercial farm at stocking densities of 2.5 and 4.6 kg per cubic meter for the APL and APH treatments, respectively. Moreover, growth and feed conversion of fish were negatively influenced by stocking density, but total biomass yield increased with increasing density of fish. Res., 33 (10): pp777-784. [4] R.C. Barrows. Biochem., 20 (1) (1999), pp. Density (kg/m 2) of submerged macrophytes was recorded once every three months by “Quadrant” method. Fish stocking density (no/ha) was recorded as the number of carps (total and by species) stocked annually in each baor. The stocking density is one of the most important parameters of fish growth and productivity in farming activities. Farming of common carp, silver carp, silver barb, tilapia and catfish is encouraged by government and development organizations so that farmers in the rural areas can have fish for their own consumption and income generation. The experiment demonstrated a remarkable technological plasticity in both experimental variants, whereas, in terms of technological performance indicators, it was found that the application of lower stocking densities lead to higher crop biomass. Angling Information: Recomended Safe Carp Rigs Silver and bighead carps are stocked at a size of 3-4 cm at 16.5-21/m2. This study was factorial-designed (3 arginine levels ×2 stocking densities). T2 - International Journal of Scientific Research in Biological Sciences Slaughter activities include handling, restraining, stunning and killing. Grass carp (Ctenopharyngodon idella Val.) stocked at a low density (29 kg ha −1) to one of two small ponds significantly reduced the biomass of aquatic macrophytes (especially of the filamentous alga Cladophora globulina Kütz.) farming of common carp and rainbow trout, as well as other economically relevant species. 2002. doi.org/10.1016/0044-8486 (1993) 90272-Z.
