Article Synopsis
- Butterflyfishes are important coral reef residents with high hybridization rates and significant evolutionary implications, though there's limited understanding of their karyotype evolution.
- An extensive cytogenetic study of 20 butterflyfish species revealed a stable karyotype characterized by 2n = 48 acrocentric chromosomes shared by most species, except for two with unique structural variations.
- The analysis showed minimal chromosomal reshuffling and similar karyotypic patterns across geographical regions, highlighting the species' adaptability and potential for hybrid viability.
Karyotypes of four catfishes of the genus Scopoli, 1777 (family Bagridae), Fowler, 1937, Roberts, 1992, (Bleeker, 1846) and (Bleeker, 1851), were analysed by conventional and Ag-NOR banding as well as fluorescence in situ hybridization (FISH) techniques. Microsatellite d(GC), d(CAA), d(CAT) and d(GAA) repeat probes were applied in FISH. The obtained data revealed that the four studied species have different chromosome complements.

The freshwater family Siluridae occurs in Eurasia and is especially speciose in South and Southeast Asia, representing an important aquaculture and fishery targets. However, despite the restricted cytogenetic data, a high diploid number variation (from 2n=40 to 92) characterizes this fish group. Considering the large genomic divergence among its species, silurid genomes have experienced an enormous diversification throughout their evolutionary history.

In this study, karyotypes and other chromosomal characteristics of 15 species from eight genera were examined using conventional and molecular cytogenetic protocols. Our results showed the diploid number (2) to be highly divergent among species, ranging from 2 = 40 to 92, with the modal frequency comprising 56 to 64 chromosomes.

However, Clarias species have also been introduced in many different countries and represent the most widespread catfishes in the world. These fishes are also known as "walking catfishes" due to their ability to move over land.
