Species | Development state | Trait | Primary Data | Secondary Data |
Aristichthys nobilis | Egg | Egg Buoyancy | They produce eggs that are semi-buoyant and require a curent to float | Pelagic |
Aristichthys nobilis | Larvae | Larvae behaviour | One day after fertilization, larval bighead haTch and enter the ichthyoplankton drift. Seven days after hatching, bighead carp larvae migrate to shore | Demersal |
Aristichthys nobilis | Female | Age at sexual maturity | Reach sexual maturity at ages 3 through 9 depending on the environmental conditions [Both sex] | 3.0 year |
Aristichthys nobilis | Female | Length at sexual maturity | 50-70 [Both sex, in Asia and Europe] | 60.0 cm |
Aristichthys nobilis | Female | Weight at sexual maturity | 5-10 kg [Both sex, in Asia and Europe] | 7.5 kg |
Aristichthys nobilis | Male | Age at sexual maturity | Reach sexual maturity at ages 3 through 9 depending on the environmental conditions [Both sex] | 3.0 years |
Aristichthys nobilis | Male | Length at sexual maturity | 50-70 [Both sex, in Asia and Europe] | 60.0 cm |
Aristichthys nobilis | Male | Weight at sexual maturity | 5-10 kg [Both sex, in Asia and Europe] | 7.5 kg |
Aristichthys nobilis | Male | Male sexual dimorphism | Males generally mature one year earlier and at smaller size than females | Absent |
Aristichthys nobilis | Spawning conditions | Spawning season | In Asia, bighead carp generally spawn between April and June with a peak in late May | ['April', 'May', 'June'] |
Aristichthys nobilis | Spawning conditions | Spawning temperature | Optimum temperature for spawning is 22-26°C, and must be greater than 18°C | 24.0 °C |
Aristichthys nobilis | Spawning conditions | Spawning water type | Spawning typically occurs at the confluence of two rivers, behind sanbars, stonebeds, or islands. These areas are characterized by rapid current (>0.8 m/s) and mixing of water | Flowing or turbulent water |
Aristichthys nobilis | Spawning conditions | Spawning release | Bighead carp often have two or three spawning periods per year [Extended spawing period or multiple spawning] | Multiple |
