“…Thfs family consists mostly of marine species but anadromous and freshwater representatives also occur (NELSON 1976). While marine and some anadromous species (genera Serranus, Epinephelus, Dicetrarchus, Lateolabrax) posses subtelocentric and acrocentric chromosomes in their complements only, in some other anadromous and freshwater species as well (genera Epinephelus, Morone, Lateclabrax, Corecperca) 1 pair of meta-to submetacentrics is present and there are 2 pairs of such elements in the sets of other freshwater species (genera Coreoperca, Siniperca) (NATARYAN and SUBRAHMANYAM 1974;CATAUDELLA et al 1973;KANG and PARK 1975;UENO and OJIMA 1977;RAcHUN et al 1978;VASILEV 1978;KITADA et al 1981;YANG 1982;ALvAREZ et al 1983;SoFRADZHIJA 1985). This apparent parallelism between chromosomal evolution of Serranidae and Percidae indicates that the same selective factors connected with the adaptation from marine to freshwater environment and changing the karyotypes of some serranids, played very likely also an important role in the karyotype differentiation of percids in Europe.…”

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.

“…In Perciform fishes, the basic chromosome number has been considered as 48, since 2n=48 occurred in number of species studied (Post 1965, Nayyar 1966, Ohno et al 1968, Chen and Ebeling 1971, Ueno and Ojima 1977, Ojima and Kashi wagi 1979. Abe (1976) stated that the karyotype of the freshwater species might have been derived from that of the marine species or less freshwater adopted forms in Perciformes.…”

CYTOLOGIA

Family Nandidae includes 7 genera and 10 species of fishes (Nelson 1976). This family has been split in various ways by past authors. Barlow et al. (1968) in a de tailed and comprehensive study, erected a new family for Badis badis and concluded that it has descended from a proto-anabantoid stock. Gosline (1971) recognized three families-Badidae, Nandidae and Pristolepidae, and placed them at the start of Percoidei. He believed them to be related to the Anabantoidei and suggested their placement with them. Liem (1970) in a detailed myological and osteological study with a functional analysis of the feeding apparatus, argues convincingly that Nandi ds and Anabantoids show no phylogenetic affinity and considered Nandids to re semble relatively advanced members of Percoidei. The present cytological studies on Nandus nandus and Badis badis of the family Nandidae were taken up with a view point of finding their cytotaxonomic status. Materials and methodsBoth Nandus nandus and Badis badis were collected from the side pools of the New Khul at Gho-Manasan, Jammu (J and K; India), with the help of hand net and casting net gears. During collection trips only males of N. nandus were encounter ed. Fishes were brought alive to the laboratory. N. nandus specimens received an injection of 0.5% colchicine solution at the rate of 1ml/100g body weight for 3 hrs, whereas B. badis individuals being quite small in size, were allowed to swim in a dilute solution of colchicine (0.005%) for 6-8 hrs. Testes and different somatic tissues like gill and kidney used for chromosomal preparations, were kept in 0.075 M KCI for 20 to 30 minutes and later fixed in Carnoy's fixative (3 parts ethanol: 1 part glacial acetic acid). The slides were prepared using air-drying Giemsa staining technique.The chromosomes were classified following Levan et al. (1964). Meta-, sub meta-, and subtelocentrics were taken as biarmed and telocentrics as mono-armed for purposes of calculating the fundamental arm number. ResultsEight specimens of Nandus nandus and ten of Badis badis were employed for karyotypic analysis. Best results were obtained from both testicular as well as soma tic tissues (kidney and gill).

“…Improved techniques for the preparation of fish chromosomes were developed after the 1970s Nagpure et al (2001).Tissue cultures Roberts (1964), squashing technique of the testis, and other karyotypic techniques have accompanied the advancement in cytogenetical studies of teleostean fishes. Roberts (1964); Ohno et al (1965), embryonic tissues or haematopoetic materials Simon (1963); Yamada (1967), smearing technique from gill epithelium McphaiL and Jones (1966); Stewart and Levin (1968), solid tissues like kidney Ojima et al (1972); Arai (1973); Ueno and Ojima (1977), from regenerating fin tissue Cattin and Ferreira (1989); Volker et al (2005) and air drying techniques Eicher (1966); Bertollo et al (1978); Thode et al (1988), together with colchicine treatment Yamazaki (1971). Dropping method was used in most previous studies to distribute cells from different tissues for chromosome preparation.…”

Cytogenetics is the diagnostic study of chromosomal structure and properties, as well as cell division, using a variety of methods, one of which is “karyotyping.” It refers to a method of photographing a stained preparation in which the chromosomes are organised in a uniform pattern. The advent of modern techniques such as “karyotyping” has made it feasible to visualize undetected chromosomal abnormalities such as short chromosome segments and chromosome translocations. Because such techniques enabled each pair of chromosomes to be identified separately, they have further aided our understanding of the chromosomal basis of a certain significant genetic diseases. Every organism has its own unique karyotype, which is defined by its number and shape. Karyotypic variation, on the other hand, occurs in different individuals of the same species, as well as between different species. Monitoring cytogenetic data of economically significant fishes as well as threatened fishes can hold importance of the succeeding generations. This review article highlights the variation in the chromosomal number & classification, methods of chromosome preparation and karyotypic analysis of various fish species of India with a special reference to fishes of Kashmir Himalayas.
