Monogeneans(Phylum Platyhelminthes) have been known as common parasites onto the skin and gills of cultured freshwater fishes. Infestation with these parasites result in a great loss in aquaculture industry. Some classification studies on these parasites have mostly been conducted in Japan but rarely in Korea. For the purpose of classifying monogenean parasites infesting two Korean freshwater fishes, carp(Cyprinus carpio) and loach(Misgurnus anguillicaudatus), samples captured from March 1998 to April 2000 were examined. Here we report that three different species of Monogeneans, Diplozoon nipponicum, Dactylogyrus extensus from carp and Gyrodactylus paralatus from loach, respectively. Of these the latter two parasites have never been identified in Korea.

This survey conducted to know the species of helminth parasites of cats slaughtered in Daegu during the period from July to September in 1977. A total of 65 cases of internal organs of cats was used for this examination. The results obtained were summarized as follows: 1. Six species of trematodes belong to order digenea were found; Clonorchis sinensis (Cobbolt, 1875), Heteropheys heterophyes nocens (Onji et Nisinio, 1915), Metagonismus yokogawai(Katsurada, 1912), Centrocestus sp. Echinochasmus perfoliattlus (Ratz, 1908), and Echinopharyphium sp. 2. Five species except Clonorchis sinens are firstly recorded in cats in Korea.

In order to analyze chromosome numbers and karyotypes of intestinal trematodes belonging to the genus, Metagonimus, the gonad tissues of M. takahashii, M. miyatai, and M. yokogawai were prepared and examined. The number of bivalents in the first meiotic division of M. takahashii was nine (n＝9). The diploid number of M. miyatai was observed to be eighteen (2n＝18) and their chromosomes consisted of one pair of metacentric, 7 pairs of submetacentric, and one pair of telocentric chromosomes. The diploid number of M. yokogawai was thirty-two (2n＝32) and the chromosome complements were composed of two pairs of metacentric, 11 pairs of submetacentric, and three pairs of subtelocentric chromosomes. These results could be a supporting evidence for the validity of the new species, M. miyatai, distinct from M. yokogawai.

In order to clarify infestation Pattern for the encysted larvae of digenetic trematodes from fresh-water fishes, this survey was carried out from March to September, 1983. A total of 380 fishes of 32 species wore collected with netting at the three reaches, upper, middle and lower in Mangyeong riverside area. After the fishes were dissected into small scraps, they were pressed under cover glass and examined-for the presence of those of digenetic trematodes with a microscope. The resillts obtailled were as follows; Out of a total of 380 knishes inspected, 320 fishes(84%) from 31 species were found positive with, digenetic trematode metacercariae; more than 10 species of the metacercariae Ivere detected in Pseuderasbora parva; .Gnnthepegen mtajimae, Microphysogokio yaluensis, Cultriculus eigenmanni and Gnnthopogon coreanus (more than 8 species) ; Aphyocypris chinensis (8 species) and etc. respectively. Clonorchis sinensis metacercariae were found positive from 93 fishes (25%) from 12 species and detection rates in other species of digenetic trematode metacercariae from various fishes were; Exorchis oviformis, 261 fisles (57%) from 28 species; Cyathocotyle criensalis, 47 fishcs (12%) from 12 species; Metorchis orientalis, 21 fishes (6%) from 12 species; Metagonimus yokogawai, 164 fishes (43%) from 26 species; Pseudesorchis major, 71 fishes (19%) from 18 species; Metacercaria haiegawai, 77 fishes (20%) from 25 species; Centrocestus armatus, 24 fishes (6%) from 7 species; Echinochasmus japonicus, 2 fishes (0.5%) from 2 species, and unidentified species, 34 fishes (9%) from 15 species respectively. The sums of average number of the encysted larvae of all species found in fish body/gram showed 83 in P.parva, Cobitis taenia (74.2), A. chinensis (28.5), Pseudoperilampus uyekii (26.6), G. majimae (19.6) and etc. respectively and the average peak number of each metacercaria in fish body/gram showed 21.7 C. sinensis, 245. ovifcrmis, 15, 3 M, crientalis and 6.1 5. japonicus in P. parva. 42.7 C. orientalis and 25.1 M. yohogawai in C. taenia; 8.3 C. armatus and 8.3 M. hasegawai in P. uyekii. 6.3 P. major in Carassius carassius, and 2.9 unidentified species in G, niajimae respectively.
