This study was conducted to compare the nutritional properties of cookies made with Israeli carp Cyprinus carpio (C-IC) to those made without Israeli carp (control). The proximate composition of C-IC per 100 g was 4.1 g moisture, 9.7 g protein, 29.2 g lipid, 1.4 g ash, and 55.6 g carbohydrates. Moisture, protein and ash contents were significantly higher and the carbohydrate content was significantly lower (P<0.05) in C-IC than control, but there was no difference in lipid content (P>0.05). The total amino acid content of C-IC per 100 g was 9.46 g and the major amino acid was glutamic acid (2.49 g). The mineral contents of C-IC per 100 g were 216.6 mg calcium, 193.2 mg phosphorus, 170.9 mg potassium, and 18.2 mg magnesium, which were all significantly higher than the contents of the control (P<0.05). The major fatty acids of C-IC were 16:0, 18:1n-9, and 18:2n-6. The digestibility of C-IC in the small intestine was 51.3%, which was higher than the digestibility of the control. These results suggest that C-IC have better nutritional properties than the control.

Effects of ambient nitrite, NO$_2$$\^$-/, at 1, 3, 10 and 30 mg/1, on the changes of plasma nitrite/nitrate and on hepatic drug - metabolizing enzyme activity were examined in the juvenile Israeli carp, Cyprinus carpio. When the fish were exposed to 1 and 3 mg/1 NO$_2$$\^$-/, there was an exposure duration-dependent increase in plasma NO$_2$$\^$-/ over the 96-hr period reaching 6∼7 fold excess the ambient concentration. In the fish exposed to 10 mg/1, a plateau concentration of less than 2-fold of the environment was attained in 12 hr. With 30 mg/1, however, the maximal plasma NO$_2$$\^$-/ was 41.25 mg/1 at 12 hr followed by a gradual decline. There was a concentration-dependent increase in methemoglobin (metHb) level in all NO$_2$$\^$-/ -exposed groups and a significant decrease in hematocrit value in 30 mg/l group after 96-hr exposure. Apart from the blunted increase in plasma NO$_2$$\^$-/ with higher NO$_2$$\^$-/ (10 and 30 mg/1) exposure, the ratio of plasma NO$_3$$\^$-/ to NO$_2$$\^$-/ was signifirantly higher in these groups compared to 1 and 3 mg/1. The imbalance in the plasma NO$_3$$\^$-//NO$_2$$\^$-/ at higher NO$_2$$\^$-/ exposure suggests a possible accelerated conversion of NO$_2$$\^$-/ to NO$_3$$\^$-/. Nitrite exposure did not affect the hepatic drug-metabolic activities in juvenile Israeli carp. All these data indicate that disposition of NO$_2$- differ depending upon exposed concentration and that metHb production may not be the exclusive toxic mechanism in carp.

The muscles of wild and cultured carp (Cyprinus carpio), and Israeli carp (Cyprinus carpio nudus) were analyzed for the amino acid profiles, in vitro digestibility, predicted digestibility, C-PER and DC-PER. The distribution patterns of the total amino acid profiles in wild and cultured carp were found to be very similar, although there were relatively large differences in lysine, aspartic acid and glutamic acid contents which were higher in the cultured carp. Israeli carp was 2 times as much as wild carp in lysine. The quality of muscle proteins in wild and cultured carp, and Israeli carp was predicted by the in vitro method. The protein quality of Israeli carp was higher than that of wild and cultured carp, whereas there showed a similar tend to protein quality between wild and cultured carp. The contents of hitidine, tyrosine, aspartic acid, alanine and glutamic acid in diet showed stronger positive corelation with the levels of protein deposition than those of protein intake, and those amino acids would greatly influence on amino acid composition of muscle protein in fishes.

Serum immunoglobulins (Igs) from Israeli carp were purified using affinity chromatography. Fish were immunized with purified mouse IgG, and the specific fish antibodies were purified from the immune serum on a mouse IgG-immobilized agarose gel. Rabbit anti-Israeli carp Igs (R $\alpha$ I. carp Igs) antibodies were produced following hyperimmunization with mouse IgG specific carp antibodies. SDS-PAGE analysis under reducing condition showed that Israeli carp Igs were composed of two $\mu$-like heavy chains with about 82 and 50 kd, respectively, and one light chain with about 25 kd. On immunoblotting analysis, however, R $\alpha$ I. carp Igs failed to react with the light chain. When both protein A and protein G-purified normal carp Ig were compared with mouse IgG-specific Israeli carp Ig, no significant structural differences among them were observed. To investigate if there is any homology between other fish Ig molecules, cross-reactivity of R $\alpha$ I. carp Igs against Ig molecules from 6 different fish sera and mouse control serum was checked on immunoblotting analysis. As a result, R $\alpha$ I. carp Igs responded to Israeli carp, common carp, and tilapia Ig molecules. In flow cytometry study, however, R $\alpha$ I. carp Igs appeared to recognize 42.0%, 35.8% and <5% of Israeli carp, common carp and tilapia $Ig^+$ head kidney cells, respectively. The result suggests the heterogeneity between receptor Igs on B-like lymphocytes and soluble Igs in serum. It is crucial to obtain pure fish Igs to produce reagent antibodies as tools for the study on their specific immune responses.

Since the introduction of Israeli carp into Korea for farming in 1973, there are no breeding studies on developing Korea Israeli carp (domestic) so far. This study performed gene-based cross-breeding studies to restore genetic diversity of lowered Israeli carp through continuous inbreeding, and for rapid growth and better scales. This study produced four cross-breeding groups (F1) using Koean Israeli carp and Chinese Songpu mirror carp for the improvement of growth and scale of Israeli carp in Korea. And mating scheme for breeding groups was set in consideration of the morphological analysis and genetic distance of broodstock. In addition, this study used microsatellite markers and genotype data to analyze genetic diversity and parentage analysis. As a result, the average N_A and H_E values of Korean select broodstock are 8.3 and 0.743, and F1 is 13.0 and 0.764. This study shows that the genetic diversity of F1 has been recovered over Korean Israeli carp through breeding between Korean Israeli carp and Chinese Songpu mirror carp. Common Israeli carp in Korea reached 1.7 kg in 17 months, and improved Israeli carp reached to 2.2 kg. The KC (Korea×China, KC) group was 2.52 and broodstock group was 3.15. F1 showed lower scale score (0.63) than broodstock. The improved carp (F1; CK, KC) had 20% better scales than the parent group (F0), which improved 27% in weight and 25% in scales compared to common Israeli carp. The Israeli carp developed by the genetics-based breeding grew quicker and had improved genetic diversity and fewer scales, which will be of great value for Korean Israeli aquaculture industry due to good marketability.

This study was conducted to evaluate the possible utilization and the replacing range of fish meal analogue (FMA) as a dietary animal protein source for fish meal replacer in fingerling common carp, Cyprinus carpio. Leather meal, meat and bone meal, feather meal, squid liver powder, poultry by product meal, blood meal and amino acids were selected as ingredients for FMA. fish averaging 12.5 g were fed one of five isonitrogenous and isocaloric diets containing fish meal and/or FMA as the dietary animal protein sources. Fish meal protein (0, 20, 40, 60 or 100%) was replaced by the graded level of FMA protein. The feeding trial was conducted for 12 weeks after one week of conditioning period. Percent weight gain of fish fed diets containing 20%, 40% and 60% FMA were not significantly different from that of the fish fed the control diet (P>0.05). Feed conversion ratio of fish fed diets containing 20%, 40%, 60% and 100% FMA were not significantly different from that of fish fed control diet. These findings suggest that replacement of fish meal protein by FMA could be possible up to 60% of fish meal protein in fingerling Israeli carp diets.

To investigate the species and infection rate of Tripartiella sp in three species of freshwater fish, carp(Cyprinus carpio), goldfish(Crassius auratus) and Korean catfish(Parasilurus asotus), fish cultured in the fish farms next to Yosu and in the western area of Chunbuk province in Korea was examined from April to June, 1996. The infection rate was evaluated after observing the gill and mucous from 130 fish under the microscope. The species of Tripartiella was identified on the basis of the shape and number of denticle according to methods of Bychowsky(1985) after staining the parasites with 2% methyene blue solution. All the detected-parasite was classified as Tripartiella differed from Trichodina reported previously in our country. T carassii, T californica, T rhombi from Goldfish, T rhombi from common carp, T californica from Israeli carp and T bychowsky from Korean catfish were observed. In the fish from the fish farms in the western area of Chunbuk province, the infection rate of Tripartiella sp was ranged from 6.7% to 100%, but in neither carp nor goldfish from the farms next to Yosu the parasite detected.

The differences of nutritive components in muscle and viscera of local and Israeli strains of common carp were examined. The crude lipid content in muscle was higher in the local carp than in the Israeli carp, but that in viscera was lower in the local carp than in the Israeli carp. There was no appreciable differences of crude protein and ash in viscera between local and Israeli carp. The distribution patterns of the total amino acid profiles for both local and Israeli carp were very similar. The principal amino acids were aspartic acid, glutamic acid, leucine and Iysine. They were 42 percent of total amino acids. Taurine and histidine were important part of free amino acids. Eicosapentaenoic acid and docosahexaenoic acid content in the polar lipids were high in both strains.

Growth performance and excretions of nitrogen (N) and phosphorus (P) were investigated with carp (Cyprinus carpio) with carp (Cyprinus carpio) grower fed a low pollution diets (A and B) and commercial ones (Com-1 and Com-2). A recirculated rearing system (Exp. I) and a floating net cage system (Exp. II) were employed for two feeding trials in which fish having an initial body weight of 152g and 193g were fed for 41 an 39 days, respectively. The highest weight gain, daily growth rate and protein efficiency ratio were found (P<0.05) in fish fed diet A containing 10% fish meal and 2% monocalcium phosphate (MCP) for both experiments. They also showed the lowest feed conversion ratio and daily feeding ration among treatments. Fish fed diet B containing 10% fish meal, 5% fish protein concentrate and 1% MCP showed weight gain and FCR more improved (P<0.05) than those fed commercial diets. In all groups, whole body cmpositions were not greatly different among treatment, and protein and P contents in final fish ranged from 14.3 to 15.6% and from 0.39 to 0.48%, respectively. Fish fed diet A excreted the least N which were 38.3 in Exp. I and 39.6g/kg gain in Exp. II. However, the values found in fish fed two commercial diets amounted to 59.1 and 58.9g, respectively. A significant decrease in P excretion was also found in fish groups fed diets A and B. In Exp. I, a reduction of 53.4% was shown in fish fed diet A, compared to the averaged value (18.5g P/kg gain) of two commercial groups. In Exp. II conducted using the floating net cages, fish fed diet B excreted the least P (8.6g/kg gain) among the treatment, which was followed by fish fed diet A, showing 48.6% reduction compared to the average value (18.5g/kg gain) for fish fed two commercial diets. The present results clearly showed that N and P excretions from fish culture could be significantly reduced by using the low pollution diet.
