Fingerling grass carp (Ctenopharyngodon idella), 100-120 mm total length, were exposed to various hypotonic and hypertonic waters to determine tolerance, body weight loss, and muscle tissue water content. Maturity weight is about 40 pounds with a four-foot length, but specimens to 100 pounds have been reported. They grow very rapidly, and young fish stocked in the spring will reach over 18 inches by fall. Grass carp have elongated, chubby, torpedo-shaped body forms. male grass carp which 50% of male became matured was expressed at 53cm length as shown in Fig. The natural growth of grass carp fry in length and weight is best described by the exponential equations Key ID Features: Grass carp are large fish with a torpedo-shaped body, blunt head, and moderately large scales. Length 92, 105, 157. Most Catla Carp stick to forms of zooplankton for the food of choice. In both of these countries, control is made easier by the fact that grass carp are very unlikely to naturally reproduce because of their very specific breeding requirements,[13] but elsewhere control is obtained by the use of sterile, triploid fish.

In India, grass carp are cultured as an important species in pond-based composite systems consisting mainly of Indian major carps and Chinese carps. The rate of growth was always found to be higher in those fry maintained on a mixed diet … these relations can be expressed in the following mathematical equation: y = 26081x - 1E+06 R² = 0.986 When measuring the length of the fish, be sure to measure from the lower jaw to the tail.
