Abstract:
... Between 1970 and 1990, 85% of all new electric power generating capacity is estimated to require water for cooling. This poses a question for research scientists from several disciplines of finding some productive use for the waste water required by steam generating plants. Since there is usually a finite amount of water available for cooling purposes adjacent to the plant sites, the problem becom ...

... Food selectivity by the common freshwater carp, Esomus danricus (Ham.) was studied through Ivlev's equation of electivity. The selective feeding seemed to be influenced by many factors, including the accessibility, abundance and taste, of the food items, the mechanical and physiological adaptations on the part of the fish to capture and digest those food organisms, as also the inherent and instinc ...
... A new myxosporean, Myxobolus basilamellaris sp. n., is described from carp fry and fingerlings. It forms cysts in the gill arches. Spores have polar capsules of different size, mucous envelope and lack intercapsular appendix and iodinophilous vacuole. ...
... "Arai" (washing) is a traditional cooking method of fish preparation in Japan. Carp muscle slices were washed in water (49 degrees C for 15 sec, or 0 degree C for 10 min), and examined for physical and biochemical changes. At 49 degrees C, rigor-mortis was accelerated, resulting in a marked decrease of muscle slice thickness. ATP degradation proceeded faster at 49 degrees C than at 0 degree C. Ara ...
... Inorganic gamma-phosphate liberation from adenosine 5'-triphosphate (ATP) by carp myofibrillar ATPase was measured at 0-60 degrees C to elucidate mechanisms in rigor mortis acceleration of sliced carp muscle during washing at a moderately high temperature. ATP splitting within 20 sec in the presence of 5 mM MgCl2 plus 0.25 mM CaCl2 was maximal at 45 degrees C, which agreed well with the commercial ...
... Carp respond to water hypoxia with an evaluation in the rate of gill ventilation. In order to characterize closer the adequate stimulus for the increase in respiratory drive specimens of carp, Cyprinus carpio L., were exposed simultaneously to moderate environmental hypoxia (PwO²˜ 75mmHg, 10kPa) and elevated water nitrite concentration (089 ± 0-lmmol/l) for 24h. The differential effects of these t ...
... Glutathione peroxidase (GSH-Px) activity was detected in the muscle and skin tissues from several fish species. The muscle GSH-Px showed an optimum pH at 8.0 for salmon and 8.5 for carp. Stability of salmon muscle enzyme was enhanced in the presence of reduced glutathione (GSH), but considerably decreased in the presence of tert-butylhydroperoxide. When salmon fillets were stored at -50 degrees C, ...

Abstract:
... Four feeding trials with Israeli carp, Cyprinus carpio L., were performed in cages or in ponds in order to investigate responses to lysine supplementation of low protein carp feeds under different practical conditions. In each of the trials one of the basic conditions was different: fish size--small (80-125g) or large (560g); temperature--22°C or 26°C; density--cages or ponds. In each trial 2-3 ra ...
... The Km values of 5'-nucleotidase against IMP markedly increased below 6 degrees C in the case of 32 degrees C-acclimated carp muscle microsomes. This caused a break point at 6 degrees C in the Arrhenius plot of 5'-nucleotidase activity against IMP at a low concentration. The discontinuity of temperature dependency was not found when a surfactant had been introduced. Muscle microsomes of carp accli ...
... Structural changes of actomyosin, the major protein of muscle, on heating have been estimated on ATPase activity. We investigated carp actomyosin molecule changes on heating based on biophysical and biochemical techniques. Actomyosin molecules began to unfold at approximately 30 degrees C Hydrophobic amino acid residues and SH groups, which had been inside the molecule, emerged to the surface. Bec ...

... Experiments were performed using ionisating radiation in order to prolong the shelf-life of two groups of refrigerated fish (Cyprinus carpio). After irradiation fish were kept at 0-2 degrees C. Non-irradiated fish reached the nonacceptability point in 16 days and irradiated fish reached that point in 31 days. No difference was found between shelf-life of whole or eviscerated fish. If fish were imm ...

Three test diets containing different levels of LF (0.01, 0.1 and 1%) were fed at 2% of fish body weight per day, i.e. LF at 2, 20 and 200 mg kg⁻¹ body weight day⁻¹ was administered orally to carp for 14 days at 20 °C. In the fish reared ...
... The ability of carp cathepsin L to degrade opioid peptides and separate myofibrillar proteins was examined. The enzyme differentially released fragments from leucine-enkephalin, alpha-neoendorphin, and dynorphin, in which the common cleavage site of the enzyme was determined to be a Gly2-Gly3 bond. A Leu5-Arg6 bond in alpha-neoendorphin and dynorphin was also commonly cleaved by the enzyme. At a p ...

Abstract:
... Sixty common carp in groups of five in four tanks per treatment were given three diets containing different increasing amounts of methionine. The aroma extract dilution analysis (AEDA) of the boiled carp fillets resulted in 32 odorants, of which 26 were identified.

... In less‐developed countries, fisheries enhancement using stocking is a common practice to manage reservoirs for biomass production. In many cases, there appears to be little control over whether the stocking activity is appropriate or necessary. Cuban reservoir fisheries have been usually managed to maximize fish biomass. Blue tilapia have been introduced and supplemented in reservoirs, and Chines ...

... A serine proteinase inhibitor, termed serpin62, was purified to homogeneity from carp serum with an increase in specific inhibitory activity of 6.2-fold and a 3% recovery rate after separation from α₁-antitrypsin. Specific inhibitory activity of serpin62 against bovine pancreatic trypsin was less than half of the specific antitryptic activity of α₁-antitrypsin. Under both reducing and nonreducing ...
... α₁-Proteinase inhibitor was purified to homogeneity from carp serum with an increase in specific inhibitory activity of 17-fold and a 3% recovery rate. The inhibitor was estimated to have molecular weight of 55,000 under reducing and nonreducing conditions, indicating its composition of a single polypeptide. The inhibitor immunologically crossreacted faintly with carp muscular serine proteinase in ...
... A single cDNA of cytochrome c oxidase subunit VIa was characterised from liver, heart and the thermogenic organ of the partially endotherm tuna fish. The amino acid sequence revealed high identity with subunit VIa from carp and trout, but low identity to subunits VIaL (liver type) and VIaH (heart type) of mammalian cytochrome c oxidase. In reconstituted cytochrome c oxidase from bovine heart, the ...
... The presence of Yersinia ruckeri, the causal agent of enteric redmouth dis- ease (ERM) in salmonids and a few other freshwater fish, has so far been reported from a variety of sources including the intestine of healthy carp. Since there are no data on the pathogenicity of this bacterium for carp, 15 fingerlings were experi- mentally infected by intraperitoneal injection of about 5 × 10⁵ cells. Thi ...
... Changes in several dielectric parameters of carp, herring and sea bass during their storage after death at 4 degrees C, 15 degrees C and 25 degrees C were examined by electrochemical impedance spectroscopy (EIS) in the frequency range of 0.1 Hz to 100 kHz. This method offers a simple, rapid and in situ measurement of the onset of spoilage. The phase angle and admittance changes are the best freshn ...
... Several recent papers have reported the difficulties in expressing olfactory receptor proteins (ORs) in heterologous systems, and proposed that some sequences in ORs have negative effects on their efficient expression. To obtain an efficient expression system of ORs, we modified N-terminal sequences of ORs through the addition of exogenous sequences. Three kinds of sequences, designated as 5HT, V, ...
... Upon heating carp myofibrils at 40 degrees C, the amount of myosin that is soluble and monomeric dropped very quickly, roughly 5 times faster than the ATPase inactivation. This rapid decrease of solubility was well explained by a rapid denaturation of the rod portion as measured by chymotryptic digestibility. Chymotryptic digestion of heated myofibrils in a low-salt medium with EDTA generated a re ...
