During the period from December in 1994 to January in 1995, the Korean endemic Cobitid fish, Niwaella multifasciata collected from the Kyongho River and Dukchon River which are tributaries of the Nakdong River, Sanchong-gun, Kyongsangnam-do, Korea. This report is a description of the gross morphology of the embryos and larvae up to the development of juvenile period of life. The eggs from the females were obtained by injecting gonadotropin and fertilized by dry method in the laboratory. Live, freshly laid eggs of this species were separative, demersal, reddish orange and average 1.8mm in diameter. The eggs began to hatch approximately about 142 hours after artificial fertilization at the water temperature of 10∼14℃. The newly hatched larvae were average 5.4mm in total length possessing yolk sac and 44∼46 myotomes. The hatched larvae showed high mortality and almost all larvae reached the adult stage. 2 days after hatching, the larvae attained average 7.1mm in total length, and were observed the melanophores at the side of the body at this time. 16days after hatchng, the larvae absorbed the yolk completely and became postlarvae. 85days after hatching, the larvae attained 17.3∼19.9mm in total length and entered the juvenile stage. All the fin rays were formed with complete set of fin rays; D.III, 6, A.III, 4, P. 9, V. 6, C.16. 110 days after hatching, the juvenile reached to 21.9∼24.6mm in total length, and the band patterns of them were very similar to those of the adult of Niwaella multifasciata.
잡종 3배체 어류 기름종개 - 왕종개 잡종군의 종간 교잡실험
이은희,김익수 한국어류학회 1995 韓國魚類學會誌 Vol.7 No.1
낙동강 상류의 여러 수계에서 거의 암컷으로 구성된 Cobitis sinensis - longicorpus complex 2배체와 3배체 집단이 높은 빈도로 출현하였다. 그 가운데, 수컷의 C. sinensis (2n=48) 및 C. longicorpus (2n=50)와 암컷 3배체 C. sinensis - longicorpus (3n=73)를 실험실내에서 인공 교잡 실험을 하였다. 그 결과 각 조합에서 얻은 자손의 체측 반문에는 부계 형질이 발현되었고 그들의 염색체는 모두 부계의 haploid genome이 포함된 diploid form (2n=48,49)이었다. 이상의 결과로 볼때 3배체 암컷인 Cobitis sinensis - longicorpus complex는 제 1 감수분열에서 uneven genome을 배제하고 제 2감수분열에 의한 반수체 ovum을 형성하는 독특한 생식 양상을 갖는 것으로 사료된다. Cobitis sinensis - longicorpus complex were commonly found in the upper stream of the Nakdong River in Korea and consisted of mostly with diploid and triploid karyotype forms. Among them, the triploid females of C. sinensis - longicorpus were artificially crossed with diploid males from C. sinensis and diploid males from C. longicorpus, respectively. The progenies from each cross produced the diploid individuals that possessed the paternal characters in their karyotypes and their body color patterns. Based on this results, we can assume that the triploid females, C. sinensis - longicorpus have a peculiar reproductive mode eliminating an uneven genome by the primary meiotic division and then producing a haploid ovum by secondary meiosis.

It was collected 30 specimens of Cobitis sinensis and 11 specimens of C. sinensis-longicorpus complex from the Imchon River, Hamynag-gun, Kyongsangnam-do, Korea in October, 1994. C. sinensis-longicorpus complex were represented by all females and triploid in karyotypes. The chromosome number of the complex have 73 composing 28 meta-submetacentrics and 45 subtelo-telocentric chromosomes. In this paper, we discussed the systematics of C. sinensis-longicorpus triploid population occuring in this area based on their karyotypes and body color patterns.
한국산 칠성장어 속(屬)무악류(無顎類)(Agnatha , Petromyzonidae)의 핵형(核型)
이은희,김익수,심재환 한국어류학회 1992 韓國魚類學會誌 Vol.4 No.2
韓國産 칠성장어屬 無顎類 3種 L. japonica, L. reissneri, L. sp.에 대한 核型을 조사하였던 바, 이들은 모두 약 160여개 정도의 dot chromosome형태였으며 染色體 數에 있어서 種間의 유의한 차이는 인정할 수 없었다. Chromosome numbers of 3 species of Korea lampreys(Genus Lampetra) were investigated. Approximately 160 small and mainly acrocentric chromsomes were present in the three species of Korean lampreys. And the diploid chromosome numbers of three species were not significantly different between the species.
