Catla - Growth

The average size of freshly hatched catla larvae is 4.7 mm and after 5, 10 and 15 days may reach an average size of 9, 15.6 and 27 mm, respectively (Jhingran, 1991). Growth is density dependent, rapid (7 to 10 cm per month) and allometric (W = 0.0069 L3.201, r = 0.999; length range: 23–91 cm, weight range: 175–12, 000 g) (Ahmed et al., 2003). The growth of the early life history stages of catla are shown in Figure 3. There is no published information on the natural growth rate of Catla catla.
