Allozyme variations among the allopatric populations of Moroco lagowskii, M. oxycephalus, M. steindachneri and M. jouyi were observed in EST-1, EST-2, PGI-1, PGI-2, PGI-3, PGI-4, ME, MDH-1 and G6PDH out of 16 loci detected by electrophoretic enzyme analyses. Two alleles, PGI-1^a and PGI-2^c, were detected only in the population of M. steindachneri and MDH-1^a with the population of M. jouyi, although no genetic markers were identified between M. lagowskii and M. oxycephalus. The genetic variation (average heterozygosity) in M. lagowskii was higher than in M. oxycephalus. However, the highest variation was observed in the population of M. steindachneri and the lowest variation was detected in the population of M. jouyi. Genetic identity value (I) between the populations of M. lagowskii and M. oxycephalus were 0. 879. M. jouyi and M. steindachneri were genetically closer to the M. oxycephalus and M. lagowskii, respectively. In summarizing the above results, it is elucidated the that four species of genus Moroco employed in this study were proved to be genetically closer to each other, so that the systematic rearrangement of genus Moroco is expected.
동사리 Odontobutis platycephala ( 망둥어과 ) 의 개체발생

Embryonic development of Odontobutis platycephala was observed. The peculiarities of eggs and development of this species are similar to those of O. obscura interrupta. O. platycephala swims along the water bottom because of its poorly developed air bladder, whereas O. o. interrupta has a well developed air bladder and rises in the water at the feeding stage. In O. platycephala, xanthophores are observed at a later stage and are weaker than in O. o. interrupta. The differences between O. platycephala and O. o. interrupta may relate to the habitat of adults; the former occurs in the middle and upper reaches of rivers, whereas the latter lives in the lower reaches and the slow-moving regions of middle reaches of rivers.
