  • 1998년 3월부터 2000년 4월까지 전라남 북도 및 충청남도 일원의 내수면 양식장에서 사육중인 잉어(Cyprinus carpio)와 미꾸리(Misgurnus anguillicaudatus)를 채집하여 아가미에서 3종의 단생흡충류를 검출하였다. 검출된 단생 흡충류는 잉어에서는 Dactylogyrus extensus(Mueller and Cleave,1932)와 Diplozoon niponicum(Goto, 1891)을, 미꾸리에서는 Gylodactylus paralatus(Gussev,1955)가 검출되었다. 이들 단생흡충 중 Dactylogyrus extensus와 Gylodactylus paralatus는 국내에서는 처음으로 보고되는 종이다.

  • Spring viremia of carp virus (SVCV) poses a significant threat to numerous cyprinid fish species, particularly the common carp (Cyprinus carpio), often resulting in substantial mortalities. This study explores the potential use of a chimeric recombinant snakehead rhabdovirus carrying the SVCV G gene (rSHRV-Gsvcv) as a live vaccine against SVCV infection. Through virulence testing in zebrafish at different temperatures (15 ℃ and 20 ℃), no mortality was observed in groups infected with either rSHRV-wild or chimeric rSHRV-Gsvcv at both temperatures, whereas 100% mortality occurred in fish infected with wild-type SVCV. Subsequently, as no mortality was observed by rSHRV-Gsvcv, three independent experiments were conducted to determine the possible usage of chimeric rSHRV-Gsvcv as a vaccine candidate against SVCV infection. Fish were immunized with either rSHRV-Gsvcv or rSHRV-wild, and their survival rates against the SVCV challenge were compared with a control group injected with buffer alone at four weeks post-immunization. The results showed that chimeric rSHRV-Gsvcv induced significantly higher fish survival rates compared to rSHRV-wild and the control groups. These findings suggest that genetically engineered chimeric rSHRV-Gsvcv holds the potential for a prophylactic measure to protect fish against SVCV infection.

  • 3종의 잉어 품종계통, 즉 이스라엘잉어, 홍백계 및 황금계의 치어성장에 관하여 비교한 바는 다음과 같은 결과였다. 1975년 $8\~11$월에 걸쳐 수면적 $316m^2$, 평균수심 55 cm, 바닥에는 부식질 진흙이 $20\~30cm 정도 깔린 못에서 상기 3품종의 치어를 혼합해서 약 $0.5g(2\~3cm)$의 치어로부터 길렀다. 공급란 사료는 어분과 정맥을 반반씩하고, 생초를 상기량의 $10\%$, 식염을 $1\%$첨가하였다. 조단백질함량은 건조상태로써 $34.9\%$였다. 총생산량은 20.588 kg(방양치어중량은 무시), 사료 공급량은 건조상태로 30.08kg였으므로 사료계수는 1.51이였다. 품종별개체중량은 이스라엘잉어는 $98\~311g$, 평균 172.6g, 홍백계는 $15\~268g$, 평균 104.1g였으며, 황금계는 $30~268g$, 평균 128.7g으로 성장했다. 이것을 백분율로 비교해 보면 이스라엘잉어를 $100\%$로 할때, 홍백계는 $60.3\%$, 황금계는 $74.6\%$의 성장을 한 것으로 된다, 그간의 수온은 평균 $20.7^{\circ}C$였으며, 평균수온이 $15^{\circ}C$ 이상인 10월 하순까지의 80일간을 주성장기간으로 보고 검토하였다. 주성장기간중의 평균 1일성장도(1일후의 체중)는 이스라엘잉어 1.075786배, 홍백계 1.06901배, 황금계는 1.07185배이다.

  • 잉어, Cyprinus carpio와 동자개, Pseudobagrus fulvidraco의 상악 하악 수염을 조직학적으로 조사하였다. 동자개의 수염은 연골성 증축(axial rod of cartilage), 신경섬유다발(bundle of nerve fiber), 표피(epidermis), 평활근 층(smooth muscle layer) 및 미뢰(taste bud)로 구성되었으며, 잉어의 수염은 표피, 신경섬유다발, 혈관(blood vessel) 및 미뢰로 구성되었다. 수염 길이에서 잉어는 상악 바깥쪽 수염(second maxillary barbel)이 상악 안쪽 수염(first maxillary barbel) 보다 길게 나타났으며, 동자개는 하악 안쪽(inner mandibular barbel), 상악 위쪽(upper maxillary barbel), 하악 바깥쪽(outer mandibular barbel), 상악 아래쪽(lower maxillary barbel) 순으로 길게 나타났다(P<0.05). 미뢰의 수를 고려하였을 때, 동자개와 잉어간의 미각에 대한 유의적 차이가 없었다(P>0.05). 아울러, 두 어종의 모든 수염에서 수염 상부의 미뢰 수가 하부의 미뢰 수 보다 높게 나타났다(P<0.05). 본 연구 결과, 동자개의 수염은 딱딱하며 굴절성인 수염(flexible and stiff type)이었으며 잉어의 수염은 연하고 유연한 수염(tender and yielding type)으로 파악되었다.

  • G Protein-coupled receptors (GPCRs) mediating wide ranges of physiological responses is one of the most attractive targets for drug development. Rhodopsin, a dim-light photoreceptor, has been extensively used as a model system for structural and functional study of GPCRs. Fish have rhodopsin finely-tuned to their habitats where the intensity and the wavelength of lights are changed depending on its water-depth. To study the detailed molecular characteristics of GPCR architecture and to understand the fishery light-sensing system, genes encoding rod opsins were isolated from fishes living under different photic environments. Full-length rod opsin genes were obtained by combination of PCR amplification and DNA walking strategy of genomic DNA isolated from olive flounder, P. olivaceus, Japanese eel, A. japonica, and Common carp C. carpio. Deduced amino acid sequences showed a typical feature of rod opsins including the sites for Schiffs base formation (Lys296) and its counter ion (Glu113), disulfide formation (Cys110 and Cys187), and palmitoylation (Cys322 and Cys323) although Cys322 is replaced by Phe in Japanese eel. Comparison of opsins by amino acid sequence alignment indicated the closest similarity between P. olivaceus and H. hippoglossus (94%), A. japonica and A. anguilla (98%), and C. carpio and C. auratus (95%), respectively.

  • This study was conducted to compare sensory and nutritional and digestive properties of the Israeli carp Cyprinus carpio muscle (ICM) by size [normal large (NLF) and small (NSF) fish], part [ventral (VM) and dorsal (DM) muscle], and commercial value [NLF, recessive (RF) or deformed (DF) fish]. In NLF, the major amino acids were lysine, aspartic acid, and glutamic acid, whereas aspartic acid and glutamic acid were predominant in NSF, DM, VM, DF, and RF. Taurine content increased with fish size, and was higher in DM than in VM, and higher in NLF than in DF but lower than that in RF. Regardless of ICM size, part, and commercial value, potassium and iron were expected in the health function, but calcium and zinc were not expected. The major fatty acids present in ICM were 16:0, 18:1n-9, and 18:2n-6, regardless of size, part, and commercial value. The digestion rate of ICM by digestive organ was lower in NLF than in NSF, and lower in VM with a high lipid content than in DM, and lower in DF than in RF.

  • The aims of this study were to optimize the processing procedure of high-quality semi-alternating temperature dried Israeli carp Cyprinus carpio (SAD-IC) and to investigate the sensory properties of the product. Based on the differences in moisture content of the dorsal and ventral muscles, high quality SAD-IC was prepared by alternating the drying temperature between 4 h at 35℃, and 2 h at 5℃, three times before final drying for 2 h at 35℃. The surface in SAD-IC produced under the optimal alternating-temperature drying process had a markedly superior browning index value and softer texture compared to products produced using constant-temperature drying. SAD-IC produced from dorsal and ventral muscle had significantly superior taste values than the raw material. These results suggest that SAD-IC has the potential to be industrialized.

  • This study was conducted to compare the sensory and enzymatic properties of Israeli carp Cyprinus carpio muscle (ICM) according to size [normal large (NLF) and small fish (NSF)], part [ventral (VM) and dorsal muscles (DM)], and commercial value [NLF, recessive (RF), or deformed fish (DF)]. There was not difference in salty of all samples. The sourness was stronger in NLF and DM than in NSF, RF, and DF, and VM, respectively. The umami of ICM showed no size-associated differences; however, those of DM, and DF and RF, were superior to those of the VM and NLF, respectively. The sweetness was also stronger in NLF than in NSF and RF, and in DM than VM. The sweetness of DF didn't differ compared to those of NLF and RF. The intensity of fish odor was weaker in NSF or DF than that in NLF, and was higher in DM than in VM. The color of ICM was bright in NSF and DF compared to NLF. Enzyme activity was very low in the muscles and high in viscera. Therefore, ICM could be used as a material for seafood products, regardless of size, part, and commercial value; however, the issue of lipid oxidation must be considered.
