  • We investigated the proper feeding frequency and satiation rate for the growth of red- and white-colored carp fingerlings in a feeding experiment. Triplicate groups of fish averaging 6.3 g were fed diets at four feeding frequencies (1, 2, 3, or 4 meals a day) and two satiation rates (satiation and 80% satiation) for 6 weeks. The survival of the fish was not affected by either the feeding frequency or the satiation rate. The weight gain, feed efficiency, and protein efficiency ratio of fish were affected by the feeding frequency and satiation rate, and increased significantly with both. The feed efficiency and protein efficiency ratio with satiation feeding of fish fed four meals a day did not differ from those of fish fed three meals a day. The daily feed intake was affected by the feeding frequency and satiation rate. The moisture, crude lipid, and ash contents of whole body were affected by the feeding frequency. Moisture and crude lipid contents were affected by feeding satiation. Based on these results, we conclude that the proper feeding frequency and satiation rate for the optimum growth of red- and white-colored carp fingerlings is four meals a day with satiation feeding.

  • Goldfish hematopoietic necrosis (GHN) affects hematopoietic organs and causes high mortality in goldfish. The causative agent of GHN is cyprinid herpesvirus 2 (CyHV-2). The purpose of this study was to detect CyHV-2 in ornamental cyprinid fish. CyHV-2 monitoring was conducted on a monthly basis for 1 year using goldfish Carassius auratus and pearlscale goldfish Carassius auratus that had been cultured at a domestic aquafarm and imported from Singapore, respectively. The results of polymerase chain reaction (PCR) assays using specific primers for the CyHV-2 helicase gene showed that 27.8% of goldfish and 33.3% of pearlscale goldfish were positive for CyHV-2. No cytophatic effects were detected in koi fin or common carp brain cells inoculated with tissue homogenates from either fish. Our data provides the useful data for establishing future quarantine and disinfection policies.

  • Japan has several unique traditional colors. The traditional colors of Japan include a collection of colors used in traditional Japanese literature, textiles such as the kimono, and other Japanese arts. Japanese color system has a long history, leading to some consistencies in color and naming. During the Edo period(1603~1867), the unique color sense of 'iki' produced many color names that are often related to mouse(nezumi) and tea(cha), and fashion color originated as kabuki actors. As for colors named after animals, the most popular appears to be the mouse, which is used to express grey tones. Recently, many fashion companies in Japan have been working on reviving an interest in traditional Japanese colors. Ordinary people of Edo named even slightly different color tones, each with individual exquisite and mind valuing 'iki' senses. They translated these into their livelihood and culture. The colorimetry result of 49 restored dyed fabrics were as follows; Hue difference was 7.8, value difference was 2.9, chroma difference was 1.8 of prefix siro. Hue difference was 3.8, value difference was 1.6, chroma difference was 1.7 of prefix usu. Hue difference was 3.5, value difference was 1.5, chroma difference was 1.4 of prefix cha. Hue difference was 6.4, value difference was 1.1, chroma difference was 1.6 of prefix koi. Hue difference was 7.5, value difference was 0.8, chroma difference was 3.3 of prefix nezumi.

  • `Kyukonyoram Dyusikbang` is an old cooking book hand-written in Korean by unknown writer, housed in Shinam-mungo of the Korea university. This book introduces Tojungbigyul and Dyusikbang(the part about food), and explains in detail how to handle emergency cases at home, take care of women who deliver a baby and give it name and so on. It can be summarized as follows. (1) 29 'Koi's seem to keep unexpected accidents and encourage people to enjoy stable life at home. (2) In this book are not only 27 ways of how to make liquors but also ways of how to cook dishes using 12 kinds of food with cold water and one kind of rice cakes. (3) It says good yeast is critical for good quality liquors and also emphasizes the. taste of good 'Jang' to enhance the taste of other food and the importance of having basic food materials and spices at home. (4) It describes in detail the day of good or ill luck while mentioning how to name a baby. It can be seen that there were somethings that were considered especially important such as the process of making Jang, the day of placing the rooftop, or the good or ill luck of people.

  • The prevalence of Centrocestus formosanus metacercariae was investigated in ornamental fish purchased from a pet shop in Chiang Mai, Thailand, including Carassius auratus (goldfish), Cyprinus carpio (Koi), Poecilia latipinna (Sailfin Molly), Danio rerio (Zebrafish), and Puntigrus tetrazona (Tiger barb). The parasite species was identified by the morphology of worms as well as by a molecular approach using ITS2. The results showed that 50 (33.3%) of 150 fish examined were infected with the metacercariae. The highest prevalence was found in C. auratus (83.3%), and the highest intensity was noted in C. carpio (70.8 metacercariae/fish). The most important morphological character was the presence of 32-34 circumoral spines on the oral sucker. The phylogenetic studies using the rRNA ITS2 region revealed that all the specimens of C. formosanus in this study were grouped together with C. formosanus in GenBank database. This is the first report on ornamental fish, C. carpio, P. latipinna, D. rerio, and P. tetrazona, taking the role of second intermediate hosts of C. formosanus in Thailand. Prevention and control of metacercarial infection in ornamental fish is urgently needed.

  • Unidentified viral disease with high mortalities has been recorded consistently since 1998 in cultured carp Cyprinus carpio in Korea. In the present study, we investigated the histopathological characteristics of the diseased carp to evaluate the relatedness to koi herpesvirus disease (KHVD). Histopathogical examination revealed severe necrotic changes and vacuous cells in the kidney, spleen, liver, pancreas, heart and intestine, but eosinophilic intranuclear inclusion, a typical characteristic of KHV infection was not detected. These results suggest that KHVD may be not a cause for the high mortality occurring among cultured carp in Korea and possibly other unknown viral disease could are related.

  • Freshwater farms are primarily located adjacent to rivers and lakes, facilitating the introduction and spread of pathogens into natural systems. Therefore, it is necessary to continuously monitor natural aquatic organisms, the breeding environment, and infection rates by pathogenic organisms. Fish and crustaceans were sampled 4 times in the Geum River estuary in 2016. The samples were analyzed for the presence of pathogens for reportable communicable diseases, including KHVD (koi herpesvirus disease), SVC (spring viraemia of carp), EUS (epizootic ulcerative syndrome) and WSD (white spot disease); parasite abundance was also examined. The dominant fish species were deep body bitterling Acanthorhodes macropterus (21.4%), followed by skygager Erythroculter erythropterus (12.7%). For crustaceans, Palaemon paucidens and Chinese mitten crab Eriocheir sinensis were dominant. Sixty fish and 36 crustacean species were examined for reportable communicable diseases. When using a specific primer set for each disease, PCR analysis did not detect any reportable communicable diseases in the samples. Some instances of Dactylogyrus, copepods, nematodes and metacercaria were detected. However, the PCR results indicated that the metacercaria were not Clonorchis sinensis.

  • With the rapid growth of information technology and the internet. the physical contents are transformed into digital contents at a fast rate. With the change. accessing the digital contents, toe service methods and the identifier used for the digital contents are not systematic and limited for use. The DOI identifier system used for the URN is also limited to academic journals or magazines and are not adequately applicable for non-academic journal or digital contents. Therefore. we have developed a unique identifier based on the analysis made on the system adopted by foreign digital contents service institutes. two types of academic journals 3 types of non-academic journals owned by KISTI that can be adopted by non-academic journals. The identifier is to be used to design and implement a digital contents service system.
