한국산 기름종개속 어류중 Cobitis taenia complex의 집단간 유전적 차이에 따른 종 분화 여부를 밝히고자 6개 집단을 대상으로 mitochondrial DNA(mtDNA)의 RFLP분석을 실 시하였다. C. taenia complex mtDNA를 10개의 6-base cutting 제한효소로 처리한 다음 그 절편 양상을 비교, 분석한 결과 6개 집단 공히 mtDNA 의 전체 genome 크기는 약 17.0$\pm$ 0.5Kbp였으며 공동절편수(F)에서 C. t. taenia 2개집단과 C. t. stria와 C. t. lutheri 4개 집단 간의 F값은 평균 0.263으로 차이가 있었으나, C. t. striata 와 C. t. lutheri 사이는 F=0.569로 가깝게 나타났다. 염기치환율 (p)에 있어 C. t. taenia는 C. t. striata 및 C. t. lutheri와 평균 p=0.082로 뚜렷한 종간차이를 보였으나, C. t. striata와 C. t. lutheri 집단들은 p=0.033으로 매우 가까운 유사성을 나타내었다. MtDNA 분석결과 C. taenia complex 중 C. t. taenia는 완전히 종분화가 이루어진 별종으로, C. t. striata와 C. t. lutherisms 아직 종수준의 분화가 이루어지지 않은 아종으로 분류함이 타당하다고 사료된다.

The Chromosomes of five cobitid fishes, Cobitis taenia taenia, C. taenia lutheri, C. taenia striata, C. longicorpus and C. koreensis were studied. The karyotypic studies were based on the observations from the flame-drying preparations. The results obtained such as the number of somatic chromosomes, the type of chromosomes according to the centromeric loci and the number of chromosomal arm(AN) were as follows: C. longicorpus, 2n=50, 12m-8sm-30a, AN=70; C. koreensis, 2n=50, 10m-12sm-28a, AN=72; C. taenia taenia, 2n=48, 14m-4sm-30a, AN=66: C. taenia lutheri, 2n=50, 10m-6sm-34a, AN=66; and C. taenia striata, 2n=50, 10m-6sm-34a, AN=66. Peculiarly, in the case of C. taenia lutheri the chromosome number of somatic diploid was found to be 48-51, however, the number of chromosomal arm was 66, irrespective of the difference in the numbers of each somatic genome. It was confirmed there exists the Robertsonian event, one of the chromosomal polymorphism in C.t. lutheri. It was remarked taxonomically that the karyotype of C. taenia taenia of Korea having 48 diploid chromosomes was not identical with that of Europe and Japan with 50 chromosomes. Based on the karyotype analysis the Korean cobitid fishes can be classified roughly into three species groups according to arm numbers and diploid numbers; 1) C. taenia taenia, C. taenia lutheri, C. taenia striata 2) C. koreensis, C. longicor pus, C. rotundicaudata and 3) C. granoei.

Sinca early 1930' Colitis taenia striate were introduced to the Donsgjin in Chollabukdo, where it hybridized with an endemic subspecies C. tiutheri. Protein electrophoresis revealed high levels of hybridization with intensive backcrossing occupied approximately 20 kilometers of the river. This is roughly one-half of tech historic range of the endemic species. The average frequency of introduced alleles of three diagnostic loci ranged 0.03-0.46 among 11 sites in tech svrnpatric area. Clinal patterns in allele frequencies suggest C. tiutheri were introduced in an upper reaches of the Dongjin and downstream dispersal of the introduced alleles followed. There is little linkasedisequilibrium between the diagnostic loci, suggesting the nuclear genomes of tech two subspecies are randomly associated. The evidence presented here and previously supports recognition of C. t. striata and C. t. lutheri as the typical subspecies.

한국산 기름종개의 학명사용에 정확을 기하기 위하여 우리나라 낙동강의 15개수역에서 채집된 1,472마리의 기름종개 표본과 유럽산 기름종개 표본을 비교검토하였다. 종전에 국내에서 C.taenia로 간주하였던 낙동강산 표본은 체측과 배면 반문의 수와 모양, 입수염의 길이, 및 안하극말단의 위치등의 유럽산 C.taenia와는 달리 중국산 C. sinensis와 더 유사하였다. 따라서 우리나라 낙동강산 기름종개 표본은 Cobitis sinensis et Dabry, 1874의 학명을 사용하는 것이 타당하다고 판단된다.

2, 300 specimens of Cobitis taenia lutheri were collected at the Samchon stream, Kui-myon, Wanju-gun, Chollabuk-do province from December, 1984 to November, 1985. Sex ratio and specific lateral color pattern of this subspecies were investigated. During the spawning season, May to Augustm sex dimorphisms in lateral color pattern were remarkable, that is the striped type appeared in most of males and the spotted type largely in femals. Besides the spwaning season both male and female showed the spotted type. These seasonal varaitions of the lateral color pattern were considered to be a significant biological characteristics in this taxon.

Cobitis choii, n. sp. is descirbed from 14 specimens (55.1-69.7 mm SL) collected from sand bottoms in the Miho-cheon stream, Chungcheongbug-go province, Korea. C. choii is compared with the specimens of C. koreensis, C. granoei, and C. taenia lutheri. The new species differ from them in the serrated lamina circularis at the base of pectoral fins in male, the rounded spots and small scales on the body sides, and slender caudal peduncle.

A new species of Cobitid fish, Cobitis longicorpus is described, based upon many specimens from several tributaries of the Seomjin River situated in the south western part in Korea. Cobitis longicorpus was previously reported as the crossband type of C. taenia by all ichthyologists in Korea. This is distributed in the Seomjin River and characterized by the distinctive cross-band color pattern, the black spots at the back of its opercula, and the structure of lamina circularis in male.

Morphometric, band-pattern and electrophoretic analysis on Cobitis taenia complex were performed to investigate the morphological and genetic differentiation and to clarify their taxonomic status. Intermediate types of band-pattern (C and D type) were more frequently expressed than that of types of C. t. taenia(type A) and C. t. lutheri (type B). Sexual dimorphism of band-pattern was observed not only in C. t. taenia(type A) and C. t. lutheri(type B). Sexual dimorphism of band-pattern was observed not only in C. t. lutheri but also in C. t. taenia and C. t. striata as well. Discriminant function analysis based on 19 morphological characters shows no significant differences among C. taenia complex. The degree of genic variation of C. t. striata was higher ( =1.48, P=31.2%, HD=0.009) than those of C. t. striata was higher( =1.48, P=31.2%, HD=0.082 and HG=0.009) than those of C. t. lutheri ( =1.37, P=2.7%, HD=0.058 and HG=0.065). The average genetic similarities between C. t. lutheri and C. t. taenia-C. t. striata were S=0.62 and S=0.66 respectively and these values indicate that C. t. tanenia has evolved specific level of differentiation. C. t. striata and C. t. lutheri show subspecifc level of close genetic similarity (S=0.82). Based on the divergent time estimate (Nei, 1975) it is assumed that C. t. tanenia was branched off from the other subspecies about two million years before present (MYBP) and C. t. striata and C. t. lutheri were differentiated about 0.6 MYBP. The use of C. sinesis an the scientific name for the Korean C. t. taenia, proposed by Kim and Lee (1988) seems incorrect since they are quite different in the structure of lamina circularis (Vladycov, 1935), the external morphology and distribution (Cheng and Zheng, 1987) and the chromosome number(Yu et al., 1989). Kim and Lee(1988) also argued that C.t. striata and C. t. lutheri should be treated as distinct species but the present study and other reports (Kim and Lee, 1984; Kim and Yang, 1993) do not support it. We conclude that C. t. taenia is a good species and C. t. striata and C. t. lutheri are subspecific status. Their scientific names should be revised in the future.
