Abramis brama ( Linnaeus, 1758)

Fig. 5 .

Material and dimensions.—See Table 2. Description.—The general shape is elongate to ovate or almost rhombic. The anteromedial and anterolateral edges are similarly developed, rounded and well pronounced. The small posteromedial edge is situated near the posterior end of the lapillus. This is also the case for the posterolateral edge that is represented by a pointed tip. In most specimens, the medial margin is bent and undulated in such a way that an additional edge in the middle of the medial margin appears. However, the medial margin may also be almost smooth. The posterior margin is short and displays a distinct concavity. The lateral margin can be smooth or slightly crenulated. It is generally straight but may be also rounded ( Fig. 5G ).
