“…North American percids of the tribe Etheostomatini, at least as regards to the species already karyotyped (Ross 1973;DANZMAN 1979;GoLD et al 1979GoLD et al , 1980 then exhibit the most derived karyotypes from this point of view.…”

“…Among North American Percids, one species of the genus Ammoerypta (GoLD et al 1979), 8 species of the genus Etheostoma (Ross 1973;DANZMAN 1979;GoLD et al 1980), 4 species of the genus Pereina (DANZMAN 1979;GoLD et al 1979), Perea flaveseens (Chromosome Atlas 1973, DANZMAN 1979 and Stizostedion vitreum (DANZMAN 1979) have been analyzed karyologically.…”

“…Similarly, karyotypes of Perea flavescens and Stizostedion vitreum appear to be the same being dominated by subtelocentric and acrocentric elements, too (Chromosome Atlas 1973, DANZMAN 1979). Those of Etheostomatini are then somewhat different in their morphology possessing more hi-armed elements (DANZMAN 1979;GoLD et al 1979GoLD et al , 1980. For European species, however, more detailed cytogenetic studies have been nonexistent except those on the localisation of nucleolar organizer regions (NORs) in the karyotype of Perea fluviatilis (MAYR et al 1985) and a metric analysis of chromosomes by BoZHKO et al (1978).…”

Karyotype Study of Eight Species of European Percid Fishes (Pisces, Percidae)

SUMMARY -Karyotypes of eight species of European percid fishes representing allEuropean tribes of Percidae, viz. Percini (Perea fluviatilis, Gymnocephalus cernuus, G. baloni, G. schraetser), Luciopercini (Stizostedion lucioperca, S. volgense) and Romanichthyini (Zingel zingel, Z. streber) were analyzed. Diploid chromosome numbers 2n = 48 have been found in all species analyzed. Their karyotypes are dominated by submetacentric to subtelocentric and acrocentric chromosome and differ in number of metacentric elements: one pair P. fluviatilis, S. lucioperca, S. volgense and G. cernuus to 5 pairs in G. baloni and G. schraetser. In the karyotypes of all species analyzed, the same marker chromosome pairs have been detected, viz. a pair of small metacentrics and a pair of large satellited (i.e. NORs carrying) subtelocentrics, respectively. Karyology of Percidae is further reviewed and discussed. It is postulated that chromosomal evolution of the family has been connected with rearrangements changing the centromere position on particular chromosomes but not with gross, i.e. numerical, karyotype changes.

SUMMARY: For this report, we studied the conventional karyotype and the NOR-bearing chromosomes in the toadfish Halobatrachus didactylus. We found a karyotype of 46 chromosomes made up of 8 metacentric, 12 submetacentric, and 26 acrocentric elements (FN = 66). No heteromorphic sex chromosomes were observed in the species. Metacentric chromosomes were easily classified as homologous pairs according to their morphology and L/S ratio. The rest of the chromosomes could not be accurately classified as homologous pairs because differences in chromosome size and L/S ratio were too slight between adjacent pairs within a size-ranged series. A single pair of NOR-bearing chromosomes was found. Active NORs were terminally located in a submetacentric pair of chromosomes.Key words: karyotype, NOR, cytogenetic, toadfish, Halobatrachus didactylus. RESUMEN: CARIOTIPO Y REGIONES ORGANIZADORAS DEL NUCLEOLO DEL PEZ SAPO MARINO HALOBATRACHUS DIDACTYLUS(SCHNEIDER, 1801) (PISCES: BATRACHOIDIDAE). -Se estudió el cariotipo convencional (Giemsa) y las Regiones Organizadoras del Nucleolo (NOR) en el pez sapo marino Halobatrachus didactylus. El número diploide de cromosomas 2n = 46 estuvo compuesto de 8 elementos metacéntricos, 12 submetacéntricos y 26 acrocéntricos (NF = 66). No fueron observados cromosomas sexuales heteromórficos en esta especie. Los cromosomas metacéntricos fueron fácilmente clasificados como pares homólogos según su morfología y la relación longitud del brazo largo/longitud del brazo corto (L/S). El resto de los cromosomas no pudo ser clasificado con precisión como pares homólogos debido a que las diferencias en el tamaño de los cromosomas y la razón L/S fueron muy pequeñas entre pares adyacentes dentro de la misma serie de tamaños. Fue detectado un par de cromosomas portadores de NOR. Las NOR están localizadas en la región terminal de un par de cromosomas submetacéntricos.Palabras clave: cariotipo, NOR, citogenética, pez sapo marino, Halobatrachus didactylus.

“…This is not unexpected, given that Clupea harengus has a haploid complement of 26 chromosomes (Gold et a!., 1980) and, accordingly, the probability of establishing linkage is low amongst the random loci. Obviously, too few comparisons have been made to draw significant conclusions on linkage in this species and a great deal of research remains to be done with many more pairwise comparisons yet to be examined.…”

SUMMARYSingle pair matings were performed to confirm the genetic basis of electrophoretic variants of several enzyme systems in north-east Atlantic herring (Clupea harengus) collected in spawning condition from the North Irish Sea. Mendelian inheritance of codominant autosomal alleles was established for Aat-2, Idh-2, Ldh-2 and Pgi. Crosses among Fum-1, Idh-1 and Sod homozygotes produced only homozygous offspring.This study also permitted the investigation of linkage relationships between polymorphic loci. Linkage was not observed between any two loci in the 13 pairwise comparisons made. This analysis constituted the first investigation of linkage relationships in the species.
