우리나라 양식 쥐치, Stephanolepis cirrhifer에서 분리된 비브리오의 특성
지보영 ( Bo Young Jee ),방종득 ( Jong Deuk Bang ),조미영 ( Mi Young Cho ),김진우 ( Jin Woo Kim ),원경미 ( Kyoung Mi Won ),조영아 ( Young Ah Cho ) 한국어병학회 2011 한국어병학회지 Vol.24 No.2
An epidemic was occurred in Stephanolepis cirrhifer during acclimation in laboratory tanks (water temperature was about 17℃). Diseased fish showed an unique external sign, large cloudy skin surface. We investigated the cause of the disease, and isolated one pure cultured bacterium, that was identified as Vibrio anguillarum by biochemical analysis and sequence analysis of the 16S rRNA and recA genes. During the outbreak, about 30% of S. cirrhifer showed the large cloudy skin surface, and approximately 10% of the stocked fish died. Fish were effectively cured by treatment with oxolinic acid.

Effects of various concentration of skullcap Scutellaria baicalensis in the diets on a nonspecific immunity and a disease resistance of olive flounder were investigated. After feeding trial, weight gain of fish fed 0.05% skullcap immersed group was higher than that of fish fed 0, 0.1 and 1% skullcap diet but no significant differences were observed among the experimental groups. Furthermore, no significant differences in hematological indices of olive flounder were found among the experimental groups. Lysozyme activity in the serum and kidney of the administrated group(0.05% skullcap immersed group) was significantly higher than the control group. In addition, the chemiluminescent(CL) responses of head kidney leucocytes from the 0.05% skullcap immersed group was significantly higher(P<0.05) than the control group. In the histological results, the 1% skullcap immersed group appeared to have the detrimental effects for fish health. In a challenge experiment with Edwardsiella tarda(GY-01) and Streptococcus iniae(FT5228), relative percent survival (RPS) in the 0.05% skullcap immersed group was higher than the control group injected with E. tarda(GY-01) at 4th and 8th weeks. The results suggest that the skullcap extract (0.05%) would be effective to enhance the nonspecific immunity and protective ability of olive flounder against fish pathogen such as E. tarda.

The monitoring was performed to survey the mortalities and medications occurred in the inland aquaculture farms of olive flounder in South Korea from May to October, 2012. Both of the indirect inquiry for entire inland farms and the sample survey for selected farms were carried out. The aquatic organism disease inspectors, who have the national licenses for the diagnosis and prevention of aquaticorganism diseases and have close relationship with the farms, investigated the rates and causes of mortalities according to the standard manual. The cumulative mortalities rate by the indirect inquiry on 565 farms, was calculated to 27.18%, and the mortalities rate by infectious diseases was 22.64%. Otherwise, the mortalities rate by sample survey on 60 farms was 25.50%, 19.33% of them were caused by infectious diseases. The high mortality rates were recorded by scuticociliatosis, non-infectious loss, streptococcosis, VHS, artificial eliminations, vibriosis and gliding bacterial disease. Streptococcosis and non-infectious mortality caused to serious loss in productivity and economy of the farms, because of their outbreaks in the flounder groups over 600 g. The monitoring of medications in the selected farms revealed that formalin for the treatment of external parasites, such as scuticociliates, was the most commonly used drugs in the farms. As the antibiotic medications, amoxicillin and florfenicol for streptococcosis, and oxytetracycline and neomycin expecting wide antibacterial spectrum, were frequently prescribed.

넙치 양식장 HACCP 적용을 위한 위생관리에 대한 연구
지보영(Bo-Young JEE),민진기(Jin-Gi MIN),김태진(Tae-Jin KIM),최재석(Jae-Suk CHOI),박선미(Sun-Mee PARK) 한국수산해양교육학회 2013 수산해양교육연구 Vol.25 No.5
Many sanitation control problems due to aging facilities and equipment were identified when applying an HACCP system to a flatfish (Paralichthys olivaceus) aquaculture farm. Specifically, the major problems included a lack of awareness about worker hygiene, lack of management of the use of fish medicines, and vulnerability to secondary contamination by cross-contamination owing to a failure to separate breeding tools used for healthy and unhealthy fish. Therefore, the management standards on the farm regarding the surrounding environment, facilities and equipment, breeding tools, feed and medication, and the hygiene of practitioners must be improved. The hygiene management standards were divided into different procedures such as the management of farm hygiene and environmental sanitation, facilities and equipment, fish hygiene, feed, medications, water, and the stocking and shipping of fish. For each procedure, we established the management standards, inspection period, inspection procedures, and how to deal with errors that occur, to enable hygiene management by a small number of managers. Additionally, an inspection system and record form to implement an HACCP system were developed to maintain systematic management. The management and inspection of all aspects of the farm were designed to be easily managed by the supervisor.

We identified structural and non-structural gene regions encoding major capsid protein (MCP) and DNA polymerase (DPOL) of megalocytiviruses collected from infected cultured fishes in RBIVD outbreak farms in 2013-2017 in Korea. With the two PCRs using 1-F/1-R and 4-F/4-R primer sets of the Manual of Diagnosis Tests for Aquatic Animals of the World Organization for Animal Health (OIE), amplicons were generated from the spleen and kidney tissue from approxmately ~30 fishes, including rock bream (Oplegnathus fasciatus), red sea bream (Pagrus major), and rock fish (Sebastes schlegeli), from 15 outbreak regions in the aquatic farms of the South Sea and Jeju Island. In phylogenetic analysis, complete MCP and partial DPOL genes belonged to RSIV type-subgroup2. Interestingly, these genes formed a cluster indicating closer relatedness to GSIV-K1, RIE12-1, and RBIV-C1, which were previously isolated from Japan and China, than with RBIV-KOR-TY1 isolated from Korea. However, the nucleotide sequence identities of the MCP and DPOL genes of these viruses were high, at >99.8% and >99.7%, respectively, compared with RBIV-KOR-TY1. Comparisons of nucleotide and amino acid sequences showed minimal differences between the obtained strains in the MCP gene, however, one or two nucleotide sequences substitutions of the DPOL gene were detected in nine strains, including a silent mutation detected in five strains. These findings suggest a slow rate of evolution of megalocytiviruses in this region, but the potential for mutations and new pathogenic strains warrants continuous surveillance.

The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal diseases. The paper is to estimate the direct effects of economic benefits on aquatic animal disease prevention program using economic surplus analysis. The economic benefits include changes in consumer and producer surplus owing to a reduction effect of aquatic animal mortality and the consumption recovery effect. The annual changes in producer surplus for flounder, rockfish and others cultured is estimated as 2.33 billion won totally (0.87 billion won, 1.01 billion won and 0.45 billion won respectively) and the annual changes in consumer surplus 10.15 billion won totally (6.36 billion won, 1.85 billion won and 1.94 billion won respectively). Therefore, total annual economic benefit is 12.5 billion won.

Hatchery-reared seeds provides a key source of animal protein for human consumption and restocking for fishery management. For stock enhancement program, we have inspected the hatchery-reared seeds of 33 species in 2009, 44 species in 2010, 43 species in 2011 and 46 species in 2012 for legally designated diseases. Results showed that abalone was the most abundant in the marine species group and then sea cucumber, olive flounder, rockfish and swimming crab were followed. Crucian carp was the most abundant and then mandarin fish, Korean bullhead, melanian snail and Chinese mitten crab were followed in the freshwater species group. The number of inspection for black sea bream, rock bream, scorpionfish, black scraper, and eel has continuously decreased for four years. The inspection for flathead mullet has been carried out only in 2009. The total number of inspection cases for eight pathogens in this study were 8,476 and disqualification cases were 56 (0.67%) by detection of aquatic animals pathogens such as koi herpesvirus, white spot syndrome virus, red sea bream iridovirus or viral haemorrhagic septicemia virus.
