Embryonic Development and a Simple Method for the Evaluation of Developmental Competence in Murray Cod (Maccullochella peelii) Eggs
ABSTRACT From fertilisation to hatching, we investigated the embryonic development of hatchery‐reared Murray cod eggs incubated at 20°C and determined the developmental stages. Twenty‐eight readily identifiable stages with distinct morphological features were described and illustrated. Meanwhile, a...

| Achoimre: | ABSTRACT From fertilisation to hatching, we investigated the embryonic development of hatchery‐reared Murray cod eggs incubated at 20°C and determined the developmental stages. Twenty‐eight readily identifiable stages with distinct morphological features were described and illustrated. Meanwhile, a simple and effective method for evaluating developmental competence at 1/2 epiboly was developed, which does not require the exhausting removal of egg chorion. Acute mortality was observed within 28 h post‐fertilisation, indicating that critical stages may occur during this period. The presented results may provide vital information to improve hatchery practices. |
