ジャーナル フリーGenetic analyses of red sea bream hatched from eggs spawned on different dates were carried out by using electrophoretic biochemical markers. Eggs for seeding were collected from natural spawning in tank 5 times at 5 day intervals during spawning season. We have detected significant differences in allele frequencies among the offsprings spawned on different dates. It is argued that the difference in allelic frequency caused by genetic drift is due to too few number and different in-dividuals of parents spawned on each spawning date. With this argument, we estimated that the actual number of parents genetically contributing in each spawning date varied from 8 to 16, although the total number of parents placed in tank was 130. A reduction of genetic variability was also found in the pooled hatchery samples when comparing to the wild population. The magnitude of reduction was 40% in the number of polymorphic loci, 12.2% in the number of allele per locus and 18.0% in observed heterozyosity. These results have to be considered in the artificial produc-tion of red sea bream for enhancement of natural stock.抄録全体を表示PDF形式でダウンロード (485K) -

ジャーナル フリーThe amphidromous form of ayu Plecoglossus altivelis is distributed in Japanese natural rivers flowing into the sea, and the landlocked form is restricted in the freshwater lakes. The latter form has a spawning season two months earlier than the former form. We investigated the ayu in Monobe river using isozyme markers, i.e. Gpi-1 and Mpi loci, and gonado-somatic index (GSI). The Gpi-1100 and Mpi100 allele frequencies of amphidromous form were 0.626 and 0.874 respectively, and those of landlocked form 0.343 and 0.390 respectively, were examined as a control. The samples which were collected from three sites of Monobe river showed that the allele frequencies of Gpi-1100 ranged from 0.525 to 0.652 and Mpi100 from 0.600 to 0.957 res-pectively. The samples from two sites of lower reaches did not include the landlocked form, and showed the lower GSI value. The higher GSI groups of third site of upper reaches was identi-fied as a landlocked form, and the lower GSI groups was identified as an amphidromous form based on the allele frequencies of Gpi-100 and Mpi100.
We concluded that the released fish of landlocked form disappear on the lower reaches of Monobe river at the beginning of September (in the spawning season of landlocked form). This is evidence that the landlocked form released on the lower reaches may be almost caught or finished its spawning. It was discussed that the released landlocked form of lower reaches might scarcely take part for the reproduction in the area of amphidromous populations.抄録全体を表示PDF形式でダウンロード (348K) -

ジャーナル フリーDuring an acute drop of ambient temperature from 25°C to 5°C at the rate of 0.3°C•min-1, total loss of equilibrium, decrease in heart rate and remarkable extension of time elements of ECG (P1, PQ1, QRS1 and QT1) were observed in carp Cyprinus carpio acclimated at 25°C. Oxygen con-sumption and oxygen utilization significantly decreased, while there was no significant change in minute volume of gill ventilation.During restoration of ambient temperature from 5°C to 25°C at the rate of 0.2°C•min-1, recovery from loss of equilibrium, increase in heart rate and shortening of time elements of ECG were observed. When the temperature was restored to 25°C, frequency and minute volume of gill ventilation and oxygen consumption were higher than the initial level probably owing to oxygen debt during the low temperature period.抄録全体を表示PDF形式でダウンロード (615K) -

ジャーナル フリーTo gain a better understanding of the spawning mechanism and a better sampling of the gonad for estimating gonad development in Cyclina sinensis, a detailed study of the morphology
and histology of its gonad was made. The gonad consists of a large number of acini connected with one another by gonoducts. Terminal gonoduct leading to the genital aperture formed the vesicle for an accumulation of sex products prior to spawning, and the genital aperture led to dorsal region of the inside mantle cavity of inner demibranch. The dorsal region of the gonad was occupied by the vesicle and the terminal gonoduct.
So, it is considered that the samples obtained from a part of the abdominal half of gonad are better than those from the dorsal half to estimate gonad development and gonad index.抄録全体を表示PDF形式でダウンロード (474K) -

ジャーナル フリーThe occurrence of a sibling species of the frog flounder Pleuronichthys cornutus was uncovered by population analysis of allelic variations at three enzyme loci for 272 specimens of 8 population samples collected from the eastern part of the Seto Inland Sea. The sibling species (type B) was discovered in a population sample (WK) collected at the Kiisuido Channel, and highly resembled P. cornutus (type A) in morphological features, which is commonly distributed in this area. Type B, however, could clearly be distinguished by genotypes at Mdh-B and Icd-B loci, respectively, coding for malate dehydrogenase-B and isocitrate dehydrogenase-B. All the specimens of type B showed genotype B2B2 at Mdh-B locus and B3B3 at Ied-B locus. In the population sample WK, a remarkable homozygote excess was observed at these two loci, all the remaining specimens except the genotypes mentioned above were type A which had genotypes B1B1 at Mdh-B locus and B1B1 at Icd-B locus, and no heterozygotes were found at these loci. At another locus coding for α-glycerophosphate dehydrogenase, the same homozygote excess was demonstrated, and different alleles were predominant in types A and B.
Morphological examination of the two types revealed that the number of dorsal, anal and ventral fin rays was fewer in type B than in type A, and the differences were statistically significant in most cases, but differences as to several other meristic characters and relative growth of body parts to body length were not significant. Differences in spots and coloration on the body surface and the possibility of isolation by a difference in spawning season between the two types are dis-cussed.抄録全体を表示PDF形式でダウンロード (2518K) -

ジャーナル フリーAplysia juliana had antibacterial and antitumor glycoproteins in its reproductive organs. A major active factor isolated from the genital mass was a glycoprotein having a molecular weight of 375, 000. It was composed of non-covalently bonded subunits of a molecular weight of 78, 000. A similar glycoprotein was also isolated from the eggs laid. These molecules are closely related in their antigenic specificity to the antibacterial glycoproteins (aplysianins) found in the corresponding organs of A. kurodai. Antibacterial activity of fertilized eggs disappeared by the time embryos assumed their veliger forms. From these observations we assume that aplysianins and related glycoproteins serve as a part of defense system of eggs in early stages of prehatching development of Aplysiidae.抄録全体を表示PDF形式でダウンロード (1376K) -

ジャーナル フリーTo examine the hydrodynamic characteristics of the saucer-shaped otter boards made of plastic, their camber is varied from 0 to 25 percent at intervals of 5 percent. The lift force and drag force of the otter boards are measured by three components load cell in the flume tank. The lift coefficient, drag coefficient and lift-drag ratio are calculated for attack angles between 0 and 60 degrees.
The maximal lift coefficients of the otter boards for camber from 0 to 25 percent are obtained at attack angle from 30 to 35 degrees. The drag coefficient gets greater when attack angle is gradually increased from 0 to 60 degrees.
From the points of view of the mean value of lift-drag ratio in some fixed range of attack angle where the maximal lift-drag ratio was obtained and width of attack angle in 75 percent of maximal lift-drag ratio, it is most efficient for the saucer-shaped otter boards cambered in 5 percent that we have experimented.抄録全体を表示PDF形式でダウンロード (506K) -

ジャーナル フリーThe first order rate constants, KD, of thermal inactivation of myofibrillar Ca2+-ATPase were determined for a total of 79 fishes of 50 families caught from six waters covering from the tropical waters, 28°C in a bottom water temperature, to the cold waters, 2°C.
The mean value of KD for fishes from a certain fishing ground tended to be lower with a higher habitat temperature; the value was lowest for the fishes from the Gulf of Thailand (28°C in the habitat temperature), followed by fishes from northern waters in the order of the adjacent waters of Amami-Oshima (25°C), Sakishima Islands (28°C), the East China Sea (17°C), the Yollow Sea (9°C), and off Kushiro (2°C). A significant, negative, logarithmic functional correlation was seen between the bottom water temperature of a fishing ground (t) and the mean value of KD for fishes inhabiting there (-KD); their rela-tion is formulated as below.
ln KD=-0.1013t+5.611
Similar influences of habitat temperatures on KD were also seen for a fish from two areas of different habitat temperatures, though the degree of the influence was somewhat variable by fish species.
Fishes with higher values of ΔK32, the increasing rate of K value, tended to show higher values of KD.抄録全体を表示PDF形式でダウンロード (479K) -

ジャーナル フリーThe present study elucidated factors affecting the propagation of Grammatophora marina (Lyngb.) Kuetz. found on the nori thalli. The following results were obtained: 1) The mucilage pores of this species looked like the compound eyes were located on the valve side. 2) The range of the optimal temperature for good propagation was 15-25°C. 3) The optimal light intensity was above 5, 000 lx at 15°C and 2, 000 lx at 20°C. 4) The species grew optimally under the value of chlorinity from 14.1 to 15.8‰ at 15°C and 20°C. 5) The optimal pH was 8.0-9.0 at 15°C and 20°C. 6) Inorganic nitrogen, borate, silicate and thiamine HCl were necessary for the propaga-tion, and especially the first two compounds were essential. 7) When the inorganic nitrogen was rich in media, the propagation was accelerated by a few amino acids released from the nori thalli, while the lack of inorganic nitrogen caused to use several amino acids as the nitrogen source of the propagation.
These results of the laboratory experiments were made to speculate about the propagation of this species in the nori cultivation ground.抄録全体を表示PDF形式でダウンロード (1213K) -

ジャーナル フリーRemovability of orthophosphate in seawater with the Acid Treated Clay (ATC) developed as an algicide was studied by examining the direct application of ATC to seawater samples under various pH conditions and orthophosphate concentrations.
In the case of direct application of ATC, the minimum and maximum residual phosphorus (P) concentration was at pH 6 and pH 8.5, respectively. Above pH 8.5, P concentration was de-creased. ATC requirement to decrease P concentration from 0.1mg P/l to 0.01mg P/l was 200mg ATC/l at pH 8.2.
The maximum adsorption of orthophosphate to ATC floc was at pH 5. The adsorbed P in ATC was 1.8mg/g (maximum) at pH 5 and also 0.4mg/g at pH 8.2.
From these results, it was suggested that mechanism of removal of orthophosphate by direct application of ATC was to be as follows, 1) formation of aluminum phosphate and coprecipitation with ATC floc at about pH 6, 2) adsorption of orthophosphate in ATC floc (aluminum hy-droxide) at pH 8.5, and 3) formation of Ca-PO4 and Ca-Al-PO4 complex at above pH 8.5.抄録全体を表示PDF形式でダウンロード (679K) -

ジャーナル フリーMultiple discriminant and discriminant analyses were applied to distinguish inherent differences for heavy metal contents among oysters/mussels/limpets and between oysters/mussels, oysters/limpets and mussels/limpets using the concentrations of Zn, Cu, Mn, Cr, Cd and Pb in the soft bodies of the three groups as variates.
The properties of the metal contents in limpets and mussels were perfectly distinguished from that in the oysters. The property of the metal contents in oysters was distinguished from that in the mussels ca. 70% and from that in the limpets by 80%; in mussels, from the oysters by 100% and from the limpets by ca. 36%; and in limpets, from the oysters by 100% and from the mussels by ca. 89%. The results on discriminations between the two groups were obtained as follows: the property of the metal contents in the oysters was distinguished from that in the mussels by ca. 75 % with mussel-like character of ca. 25% and from that in the limpets by 80% with limpet-like character of 20%; and the properties of the metal contents between mussels and limpets were clearly separated each other without any mixture. In respective sampling sites, where more than two groups were collected, the properties of the metal contents in the three groups were com-pletely distinguished from one another. The discrimination rates were decreased by the mixtures of the specimens grossly contaminated with heavy metals.
The orders of metal concentrations in the three groups were as follows: oysters>mussels>limpets for zinc; oysters>mussels>limpets for copper; mussels=oysters>limpets for manganese; mussels= oysters=limpets for chromium; oysters>mussels=limpets for cadmium; and limpets=mussels>oysters for lead.抄録全体を表示PDF形式でダウンロード (478K) -

ジャーナル フリーVenus clams were collected, over four periods of time: May, August, October/November 1984 and March 1985, from Wama tidal flat situated in the south-western end of Seto Inland Sea. Manganese, copper, zinc and iron in whole soft bodies were quantitatively determined. Seasonal variations of the four metal concentrations are discussed in relation to the reproductive cycle.
The concentration levels of four metals were as follows: iron>zinc>copper>manganese with seasonally considerable fluctuations in iron and manganese concentrations. This order, however, was consistently maintained throughout the year irrespective of sampling times. Manganese concentration in August decreased to about one-half of those in May, October/November and March, and was the lowest in the year. It is reasonably inferred that this reduction of manganese was induced by spawnings, particularly the discharging of ovarian substances, since the timing of reduction coincided with the final phase of spawning season and there were sexual differences in the metal contents between ovaries (high) and spermaries (low).
The results of discriminant analyses were obtained by relatively high rates of the proper characters in the four sampling times, with the four variates of manganese, copper, zinc and iron concentrations. Relatively low discrimination rate (77.27%) was found in the sample data of May, since the five sample data among 22 analytical groups obtained in May exhibited the proper character of August.
The concentration levels of three metals except copper in venus clams dwelling in the sheltered tidal flat were nearly equal to those in the wedge clams Latona cuneata inhabiting in the exposed sand beaches. Among 11 species of bivalves (7) and gastropods (4) the four metal concentrations in venus clams ranged at medium levels.抄録全体を表示PDF形式でダウンロード (464K) -

ジャーナル フリーCasing-stuffed kamaboko, vacuum-packed kamaboko and nonvacuum-packed kamaboko were prepared from the frozen kaen-surimi of Alaska pollack. The existence of three different states of water in kamaboko was suggested by the Henderson's water sorption isotherm analysis. Mono-molecular water layer was estimated by the B. E. T. equation. Three types of water (I, II, III) different in mobility were also recognized by thermogravimetry. Water classified into the state I, which was regarded as free water, was the most abundant of the three. Most of the water added secondarily to surimi in the processing of kamaboko was considered to exist as in state I. Released water on the surface and the cut surface of the cross-sections of casing-stuffed karaboko was determined. Although little water released on the surface of kamaboko in contact with the casing film was found, some part of the state I water on the cross-cut surface of slices existed already, when it was cut, as released water and was in proportion to the cross-sectional area. The released water on the cross-cut surface of slices increased a little during storage under the nonvacuum-packing condition, whereas it remarkably increased during storage under vacuum-packing conditions. The water release from vacuum-packed kamaboko may be due to the capillary action.抄録全体を表示PDF形式でダウンロード (450K) -

ジャーナル フリーVariations in degrees of fish's aversion to intermittent light in response to different wavelengths of lights and different background irradiances under projected light were studied from an ecological point of view in this report. A school of one-year-old Japanese horse mackerel Trachurus japonicus soon after being caught, were used for the experiments.
As a result, it is clarified that the fish school shows higher degree of aversion to blue intermittent light than that to red intermittent light; that, notwithstanding that the underwater energy of the blue intermittent light is only 1/6 that of the white intermittent light, both lights have almost no difference in degrees of fish's aversion. Furthermore, it is revealed that, when the intermittent light of 100lx is projected, the most prominent degree of aversion to light is seen when background irradiance is less than 0.003lx, and it decreases with increasing background irradiance but a certain degree of aversion still remains up to irradiance of 0.02lx and then, it disappears completely when irradiance reaches to 0.2lx.抄録全体を表示PDF形式でダウンロード (504K) -

ジャーナル フリーIn order to evaluate the effect of josamycin (JM) therapy on the intestinal flora of yellowtail, Seriola quinqueradiata, bacteria were isolated from the intestines of 3 fishes before and after 3 days administration of 30mg/kg JM. Intestinal bacteria were cultured aerobically on BHI, BTB teepol, MacConkey and EF agar, and anaerobically on GAM agar. Sodium chloride was incorporated in all media at 2% except in BTB teepol agar at 3%. The effect of JM administration on the intestinal microflora was compared with that of ampicillin (ABPC) and oxolinic acid (OA). After 3 days administration JM, the number of viable bacteria on EF agar decreased but the number of viable bacteria on the other medium did not decrease. The identification of 50 isolates of intestinal flora was performed on the genus level. Vibrio was the predominant genus before and after JM and ABPC administration whereas, in OA administration, Streptococcus was predominant. Thus, oral JM administration was safe to yellowtail intestinal flora because only the bacteria belonging to the genus Streptococcus decreased.抄録全体を表示PDF形式でダウンロード (299K) -

ジャーナル フリーIn order to compare the strengthening effect of various high polymers on the elasticity of the kamaboko from Alaska pollack frozen surimi, the textural parameters of the kamaboko added with each of them were measured. The high polymers examined were as follows: 1) agar powder, 2) k-carrageenan, 3) cellulose powder, 4) chitin from crab shells, 5) corn starch, 6) egg albumin, 7) gelatin powder, 8) lignin, 9) methyl cellulose, 10, 11) isolated soybean proteins Al and A2, and 12) wheat gluten, where the soybean protein A2 was the heat-denatured product of the soybean protein Al. The textural parameters were determined by the dynamic visco-elasticity test, punctual test and expressible water test. The relatively effective high polymers were 1, 2, 5, 6, 10, 11 and 12.抄録全体を表示PDF形式でダウンロード (268K) -

ジャーナル フリーThere is an optimal salt concentration of mating in the conjugal transfer of an R plasmid, and incompatibility (Inc) group C R-plasmids are characteristic in that they demand high salt concentration such as 0.34M or more in the efficient R-transfer. Both sodium and potassium salt are effective but divalent cation (Mg) are not.
Many pili-like structure of Escherichia coli carrying an Inc C plasmid Rms 417 were observed on an L agar plate which contained 0.34M salt, but few in the absence of salt. Therefore, the pili could be considered sex pili that E. coli R+ produced in the presence of a moderate amount of monovalent salt.抄録全体を表示PDF形式でダウンロード (1230K) -

ジャーナル フリーThe first component of complement (C1) was isolated from carp serum by a 6-step purification procedure: 1) affinity chromatography (I) on Blue Cellulofine, 2) QAE-Sephadex A-50 chromato-graphy, 3) gel filtration on Sepharose CL-6B, 4) Blue Cellulofine chromatography (II), 5) DEAE-Toyopearl 650M chromatography (I), and 6) DEAE-Toyopearl 650M chromatography (II). The final recovery of C1 hemolytic activity was 18%, representing a 788-fold purification. The purity of the isolated carp C1 was established by gel filtration on Sepharose CL-6B and by immuno-electrophoresis against anti-whole carp serum (rabbit). The molecular weight of carp C1 was estimated to be 1, 020, 000. The hemolytic activity of carp C1 was inhibited by EDTA treatment, but this inhibition was overcome by dialysis against a Ca2+-containing buffer. The hemolytic activity of carp C1 was destroyed by heating (50°C, 10 min) or incubation with carrageenan, but was retained when incubated with ammonia, hydrazine or zymosan. This indicates that carp C1 resembles mammalian C1 in chemical properties.抄録全体を表示PDF形式でダウンロード (1401K) -

ジャーナル フリーEffects of temperature and hydrostatic pressure on bacteriolytic, autolytic and proteolytic activities were investigated at 10-40°C and at 1-1, 021 atm using a lytic enzyme-producing bacterium Bacillus sp. V 37 isolated from coastal regions of Japan.
Lowering the temperature alone or in combination with increasing the hydrostatic pressure reduced the bacteriolytic, autolytic and proteolytic activities, but did not inhibit them completely.
Significant levels of activity were still observed even at deep-sea pressures.
The temperature characteristics of bacteriolytic activity calculated from the Arrhenius plot slightly decreased with increase in the hydrostatic pressure. Increased pressure had little effect on the autolytic activity, but it inhibited significantly both the lytic and proteolytic activities.抄録全体を表示PDF形式でダウンロード (462K) -

ジャーナル フリーEffects of smoking on the lipid oxidation of niboshi, boiled and dried anchovy Engraulis japonica, and its powder during drying and storage were investigated. Boiled anchovy was smoked for 30, 60, and 360 min at 40-65°C, and then dried by air at 25°C. Total times of smoking and air-drying was adjusted to 30h. During the drying process, peroxide values (POV) of lipids in the samples increased with decrease in percentage of remaining highly unsaturated fatty acid (HUFA) depending on smoking times. Oxidized acid contents of lipids in the samples, which were accepted with a good indication of rusting developed on niboshi, increased during drying. In-creasing rates of oxidized acid contents in non-smoked control and the sample smoked for 30 min were higher than those of samples smoked for 60 or 360 min. Similar protective effects of smoking to lipid oxidation in niboshi were found during storage.
Niboshi powder was also effectively protected from lipid oxidation by smoking although the lipid oxidation proceeded faster than that in the intact niboshi.
These results indicate that smoking for 60 min is effective in protecting lipid oxidation of niboshi during the drying and storage processes, and at least 360 min is necessary for niboshi powder to protect the lipids from oxidation.抄録全体を表示PDF形式でダウンロード (411K) -

ジャーナル フリーBacterial populations in the intestinal contents of seven coastal fishes were investigated qualita-tively and quantitatively, using seven agar media. Total viable counts ranged from 2.1×103 to 1.7×1010 cfu g-1. Three types of anaerobes, Bacteroidaceae, Clostridium and Gram-positive cocci, were isolated from dragonets, Japanese whiting, rudder fish and bambooleaf wrasse with densities ranging from 2.0×102 to 4.2×105 cfu g-1. Four of the nine subgroups of the genus Vibrio, along with genus Pseudomonas were distributed abundantly among the seven fish species, suggesting these micro-organisms are indigenous bacteria. Microfioras among coastal fishes and seawater were analyzed by the multivariate analysis using pattern similarity index.抄録全体を表示PDF形式でダウンロード (674K) -
