Abstract

Among members of the Cyprinidae family, hybridisation is more widespread than in any other group of freshwater fish. Therefore, the aim of this work has been to use two different approaches, biometric and genetic, to assess differences between common carp (Cyprinus carpio) × goldfish (Carassius auratus) hybrids and their parents. Twenty-three length measurements of 10 fish from each group have been performed. Statistical analyses of results were conducted using Levene’s, ANOVA, NIR and Kruskal–Wallis tests. Genetic analysis has been conducted by means of amplified fragment length polymorphism (AFLP) technique. The AFLP allowed us to distinguish groups of fish and showed that hybrids had more in common with C. auratus than with C. carpio.
