A production method for scaled and scaleless strain of common carp (Cyprinus carpio) at a breeding trial is developed by test-cross technique. When the fish with scaleless (Israeli strain of common carp) were crossed with scaled strain (hybrid fish between oriental and Israeli strain of the species), we can easily obtain 2 types of common carp with or without scale. The frequency of scaleless fish in this experiment was about 40% in the population, however, their growth rate was slightly higher than scaled fish after 3 months of this experiment.

시안의 만성적 조건에서 이스라엘 잉어의 생존, 섭이 및 성장에 미치는 독성영향을 파악하기 위하여 유수식방법에 의해 6주 동안 실험을 실시하였다. 시안의 만성적 조건하에 노출시킨 이스라엘잉어의 생존율은 시안농도 $151{\mu}$g/$\ell$이상에서 유의한 감소를 나타내었고, 실험종료시 시안농도 151, $289{\mu}$g/$\ell$에서 대조구에 비해 각각 15.2, $24.5\%$가 감소하였다. 섭이율은 시안농도 $151{\mu}$g/$\ell$에서는 3주, $289{\mu}$g/$\ell$에서는 1주 후부터 실험종료까지, 사료효율은 시안농도 $151{\mu}$g/$\ell$이상에서 2주 후부터 실험종료시까지 대조구에 비해 유의한 감소가 인정되었다. 성장률 및 일일성장율은 시안농도 $73{\mu}$g/$\ell$에서 6주 후에, 시안 농도 $151{\mu}$g/$\ell$이상에서는 2주 후부터 실험 종료시가지 유의한 감소를 나타냈다.

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.

This study optimized the vegetable rice porridge preparation process with Israeli carp Cyprinus carpio (VRP-IC). The optimum heating period for Israeli carp paste (IC-P) in a retort was 120 min as per yield results. Response surface methodology was performed with IC-P/[rice (glutinous rice: non-glutinous rice=6:4) (Rice, RI)+vegetable (carrot: zucchini=1:1) (vegetable, VE)] (X₁) and RI/VE (X₂) as independent variables; viscosity (Y₁), hardness (Y₂), amino nitrogen (Y₃), and overall sensory acceptance (Y₄) as dependent variables. Optimum rates of IC-P, RI, and VE were 47.37%, 24.49%, and 28.15%, respectively; predicted multiple response optimum values for the dependent variables were 20,150 mPa·s, 2,002.9 N/m2, 193.1 mg/100 g, and a 6.4 score for Y₁, Y₂, Y₃, and Y₄, respectively. Under optimum conditions, experimental values for Y₁, Y₂, Y₃, and Y₄ were 20,359.8±191.9 mPa·s, 2,015.0±9.6 N/m2, 188.1±4.9 mg/100 g, and a 6.5±0.2 score, respectively, which were not significantly different from the predicted values (P < 0.05). Results of F0 value, viscosity, hardness, volatile odor intensity, and browning suggested that the optimum sterilization period was 25 min. VRP-IC prepared under the optimum conditions was superior to commercial vegetable rice porridges in sensory evaluations.

Mirror carp, Cyprinus carpio nudus (weight 26.2±3.1 g, length 11.8±0.5 cm) were exposed to waterborne total ammonia nitrogen (TAN) at 0, 2, 4, 8, 16, 32, 64 and 128 mg TAN/L. The lethal concentration 50 (LC₅₀) of mirror carp, C. carpio nudus exposed to waterborne ammonia was 60.38 mg TAN/L. The red blood cell (RBC) count was significantly reduced by ammonia exposure, whereas there was no significant changes in the hemoglobin concentration and hematocrit value. In the plasma components, glucose, total protein, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were significantly increased by ammonia exposure. The results of this study suggest that the ammonia exposure to C. carpio nudus affects the survival rates, hematological parameters and plasma components as toxicity.

This study examined whether N-acetylcysteine (NAC), a glutathione precursor, could attenuate toxic effects of three fish anti-parasitic agents, trichlorfon, hydrogen peroxide ($H_2O_2$) and formalin, all of which are known to exert side effects through free radical production. Common carp Cyprinus carpio were fed with NAC (approx. 50 mg/kg/day) for 3 consecutive days prior to anti-parasite bathing for a 24 hr period. Mortality rates were examined during this 24 hr bathing period, and selected hematological and biochemical parameters were also assessed at the termination of anti-parasite exposure. The mortality rates and plasma glucose elevations caused by all three anti-parasitics were significantly reduced by NAC pretreatment. Trichlorfon, but not $H_2O_2$ or formalin, elevated plasma levels of aspartatetransaminase (AST) and alanine-transaminase (ALT), and these elevations were attenuated by NAC. There was no change in hematocrit values in any treatment. The results provide evidence for the attenuating effects of NAC against toxicity caused by anti-parasite agents that act through free radical-producing properties. The results found in this study also suggest that NAC may be administered to fish to minimize toxicity in fish parasiticide use.

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.
