DOI : 10.4194/1303-2712-v16_3_26 Viewed : 1650 - Downloaded : 1271 The postembryonic development of the asp, Leuciscusaspius (Linnaeus, 1758) pseudobranch using the technique of histological section and microscopy was done. The morphometricand histological analyses revealed that the morphology of asp pseudobranch changes during early ontogeny of larvae. Histological observations indicated that the pseudobranch was the lamellae-free type just after hatch, then lamellae are fused but the filaments stay free. Generally, the basic structure of the pseudobranch of asp larvae since 14 dph consisted of several rows of parallel lamellae. From 14 dphpseudobranch cells, pillar cells, epithelial cells and lacunar tissue were noted in the asp larvae pseudobranch. Neither chloride cells nor mucus cells were present at this structure, similarly to other fish species possessing covered type of pseudobranch.
