Ichthyotaxonomy, Morphometrics & Anatomy
- Diadromous Migration Classifications in Fishes:
- Catadromous: Fishes that spend the adult feeding and somatic growth phase of their lives in freshwater and migrate downstream to the sea to spawn and breed (e.g., freshwater eels, Anguilla bengalensis, Anguilla rostrata).
- Anadromous: Fishes that spend most of their life growing in the marine environment and migrate up into freshwater rivers to reproduce (e.g., Hilsa Tenualosa ilisha, Atlantic salmon Salmo salar).
- Amphidromous: Fishes that migrate between fresh and salt water for reasons other than reproduction (e.g., juvenile feeding).
- Potamodromous: Fishes whose migrations occur entirely within freshwater river systems.
- Correct Option: Option 2 (Catadromous fish).
