Early life stages of development of the red porgy Pagrus pagrus (Pisces, Sparidae) in captivity, Argentina
The early life history, from egg to juvenile, of red porgy Pagrus pagrus, in captivity is described. Yolk larvae were hatched 50 hours after fertilization, at 18°C water temperature. The opening of the mouth took place between the third and fourth day after hatching, corresponding to 2.6-2.8 mm noto...

| Sumario: | The early life history, from egg to juvenile, of red porgy Pagrus pagrus, in captivity is described. Yolk larvae were hatched 50 hours after fertilization, at 18°C water temperature. The opening of the mouth took place between the third and fourth day after hatching, corresponding to 2.6-2.8 mm notochordal length. The transformation stage began at 9 mm standard length, approximately 40 days after hatching. The appearance of the fins favored the displacement of pelagic larvae towards the bottom, acquiring their demersal habit during the juvenile stage |
