Species | Development state | Trait | Primary Data | Secondary Data |
Ctenopharyngodon idella | Egg | Egg Buoyancy | Currents carry the eggs and larvae to the quiet water at the tributary mouth | No category |
Ctenopharyngodon idella | Larvae | Initial larval size | The larvae captured (6.1-7.9 mm TL) ranged in age from 1 to 7 posthatching | 7.0 mm |
Ctenopharyngodon idella | Larvae | Larvae behaviour | Currents carry the eggs and larvae to the quiet water at the tributary mouth | Demersal |
Ctenopharyngodon idella | Larvae | Temperature during larval development | Water temperature at the time of capture ranged from 23 to 28°C | 23.0 °C |
Ctenopharyngodon idella | Spawning conditions | Spawning period duration | We captured larvae as early as 23 May and as late as 15 July; however, most of the larvae were taken within a 6-d period in late May [The long breeding season was evident in our samples] | 23.0 weeks |
Ctenopharyngodon idella | Spawning conditions | Spawning water type | Adults spawn upstream in the tributaries [high current velocities and long segments of unimpounded river] | Flowing or turbulent water |
