Species | Development state | Trait | Primary Data | Secondary Data |
Ictalurus punctatus | Egg | Egg size after water-hardening | Egg production by individual females was considered successful if eggs appeared normal ( yellow and ~ 5 mm in diameter) | 5.0 mm |
Ictalurus punctatus | Egg | Egg adhesiveness | Formed a cohesive mass following activation | Non-Adhesive |
Ictalurus punctatus | Spawning conditions | Spawning temperature | Ambient water temperature in all culture facilities ranged from 23 to 27°C. Warm (30°C) water was added if possible to attempt to maintain water temperatures within the defined spawning range | 23.0 °C |
Ictalurus punctatus | Spawning conditions | Mating system | Females and males are placed in ponds containing spawning containers that stimulate natural nesting sites, and are allowed to form spawning pairs | No category |
