Karyotype and nucleolar organizer regions (NORs) were studied in the longfin carp (Labiobarbus leptocheilus) from Mekong Basin of Thailand. The mitotic chromosomes were directly prepared from kidney cells from five male and five female fishes and stained by conventional staining and Ag-NOR banding. The chromosome number was 2n=50 and the fundamental number (number of the chromosome arms, NF) was 86 in both male and female fishes. The karyotype was composed of six large metacentric, eight large acrocentric, six large telocentric, four medium metacentric, six medium submetacentric, six medium acrocentric, four medium telocentric, four small metacentric, two small acrocentric and four small telocentric chromosomes. The Ag-NOR banding showed a single pair of Ag-NORs adjacent to the telomeric position of the short arm of the chromosome pair 8.

This is the first nucleolar organizer region (NOR) polymorphism and chromosome analysis of Banggai cardinalfish (Pterapogon kauderni Koumans, 1933). Kidney cell samples were taken from 10 male and 10 female fish. Mitotic chromosome preparations were prepared directly from kidney cells. Conventional and Ag-NOR banding techniques were applied to stain the chromosomes. The results showed that the diploid chromosome number of P. kauderni was 2n=46, and the fundamental number (NF) was 92 in both males and females. The types of chromosomes were 6 large acrocentric, 4 medium metacentric, 14 medium submetacentric, and 22 medium acrocentric chromosomes. The results indicated that the short arm subtelomeric of the acrocentric chromosome pair 13 showed clearly observable NORs. This finding exhibited that three NOR polymorphism patterns were found: 1) homomorphic which shows an equal size of both chromosome pair 13 (13a13a), 2) heteromorphic that displays different sizes of NORs of chromosome pair 13 (13a13c) and 3) heteromorphic which is found in only one homologous chromosome pair 13 (13a13b). There was no observation of strange size chromosomes related to sex. The karyotype formula for P. kauderni was: a m sm a 6 4 14 22 2 (diploid) 46 = L + M + M + M n

NORs can be the perfect markers to display wide chromosomal polymorphism within and between species in many groups of fish.…”

SummaryThe present study reports the first finding of the NOR (nucleolar organizer region) polymorphism and chromosome analysis in the John's snapper (Lutjanus johnii) from Thailand. Kidney cell samples were taken from four male and four female fish. Mitotic chromosome preparations were conducted using the standard squash technique, as well as directly from kidney cells. Metaphase spreads were performed on microscopic slides and then air-dried. Conventional and Ag-NOR banding techniques were applied to stain the chromosome. The results showed that the diploid chromosome number of L. johnii was 2n=48, and the fundamental number (NF) was 48 in both male and female. Karyotpes were present as 28 large telocentric, 16 medium telocentric, and 4 small telocentric chromosomes. No strange-sized chromosomes related to sex were observed. The results indicated that the long arm subcentromeric of the telocentric chromosome pair 1 showed clearly observable NORs (satellite chromosomes). In addition, a heteromorphism of one female had differentsized NORs in chromosome pair 1 (1a1b), while three females and four males had equal-sized NORs in chromosome pair 1 with a homomorphism (1a1a). The karyotype formula for L. johnii is as follows:2n ( The family Lutjanidae (lutjanid fish), or snappers, is a family of perciform fishes, mainly marine but with some members living in estuaries and entering freshwater to feed. Some of them are important food fish. Species from the family Lutjanidae represent one of the major resources for marine fishery. Lutjanid fish are widespread over the Atlantic, Pacific, and Indian oceans. Fishes of the family Lutjanidae occur in tropical and subtropical seas from shallow waters to depths of approximately 550 m. This family comprises 17 genera with about 105 species, and the genus Lutjanus with 64 species is the largest genus including over half of the species in this family (Nelson 2006).In spite of the high number of species and its worldwide distribution, the family Lutjanidae has been little investigated, and contradictory results have been obtained concerning the phylogenetic relationships and the taxonomic status of some of its genera and species. For example, the validity of the genus Ocyurus has been extensively discussed (Chow and Walsh 1992, Domeier and Clarke 1992, Loftus 1992, leading some authors to propose the synonymization of genus
