ジャーナル フリーEight groups of eyed eggs were subjected to gamma-ray doses of 100, 200, 400, 500, 600, 800, 1000 and 2000 rads, respectively. All the groups were incubated after irradiation and the fry were reared until they reached a mature stage.
There appeared no differences in the rate of hatching among the eight groups. However, all the fry which had received above 800 rads of the gamma-irradiation died before reaching the advanced fry stage, whereas 50 to 80% of the fry which were subjected to less than 600 rads survived. A high percentage of deformed alevins was observed in the 2000 rads group.
In the groups exposed to more than 400 rads of gamma-rays the percentage of fully muture fish decreased with the increase in gamma-ray dose. This phenomenon was observed more markedly in the females than in the males.
In the groups which received less than 200 rads the percentage of mature fish was similar to that of the unexposed control group.抄録全体を表示PDF形式でダウンロード (360K) -

ジャーナル フリーNo chromaticity-type S-potentials were recorded from the retina of skipjack tuna and two other related species. This, together with a maximal response at about 497 nanometers from the only spectral pattern of the luminosity type, indicates that the species are probably color-blind. Ganglia cell responses and electroretiongrams also supported this view.抄録全体を表示PDF形式でダウンロード (224K) -

ジャーナル フリーMorphological and biochemical characteristics were examined on four strains of the bacteria causative of “pseudotuberculosis” among yellowtail (Seriola quinqueradiata), and on a strain of Pasteurella piscicida, Janssen et Surgalla.
The observation that the pseudotuberculosis organisms were identical with P. piscicida was confirmed.
These organisms were all Gram-intermediate, non-motile rods. A peculiar morphological feature of the organisms is the transformation from rod-shaped cells in the early logarithmic growth phase to small coccoids or cocci in the stationary phase. The organisms gave positive Kovacs' oxidase reaction; fermented glucose in Hugh-Leifson's medium, and produced acid but no gas from a few other carbohydrates such as fructose, galactose, and mannose. They were sentistive to most of the antibiotics and antimicrobial drugs, including penicillin and polymyxin B; were halophilic; and did not grow at pH lower than 6.1.
Although the cells of these organisms did not show any typical coryneform appearance, nevertheless, the above characters suggest that they have a close relationship with coryneform bacteria and genus Arthrobacter seemed to be the most suitable genus to which they belong.抄録全体を表示PDF形式でダウンロード (1593K) -

ジャーナル フリーA single metacercaria of the genus Proctoeces ODHNER (Fellodistomatidae: Trematoda) from an abalone, Haliotis discus hannai INO (Archaeogastropoda: Gastopoda), is discribed. The metaercaria was found in a new locality in the northern regions of the Sea of Japan and on a new second intermediate host for the genus Proctoeces. The abalone was collected along the shores of Funadomari, Rebun Island, Hokkaido. The metacercaria, from between the epipodium and mantle of the host, was unencysted with well developed internal organs but was observed to be not of the progenetic form. Althogh it seemed to be morphologically related to P. maculatus (LOOSS) ODHNER or to P. subtenuis (LINTON) HANSON, specific identifications did not prove fuccessful because of only a single specimen and its lack of eggs.抄録全体を表示PDF形式でダウンロード (275K) -

ジャーナル フリーVitamin B12, thiamine and biotin concentrations in the surface water of Lake Tsukui have been determined over a period of two years, in 1970 and 1971, by the use of microbiollogical assay methods. The assay organism used for the determination of vitamin B12 was Lactobacillus leichmannii ATCC 7830, for thiamine was the marine yeast, Cryptococcus albidus, and for biotin the marine bacterium, Achromobacter sp. strain yH-51. Dissolved vitamin B12 concentration decreased remarkably and particulate portions increased considerably in the surface water at most times when diatoms, Cyclotella sp., Fragilaria crotonensis and Synedra acus, were dominant. Thiamine and biotin concetnrations increased very much in both dissolved and particulate forms in the surface water in such times when diatoms were dominant. From the results, the possible importance of vitamin B12 as one of the ecological factors in Lake Tsukui is suggested.抄録全体を表示PDF形式でダウンロード (404K) -

ジャーナル フリーA taxonomic investigation of the bacteria, 453 strains of gram negative and monopolar flagellated rods, taking part in the precipitation of calcium carbonate, is described in this paper. The method of classification according to Bergey's Manual of Determinative Bacteriology and SHEWAN's scheme was adopted in this study.
The results obtained were summarized as follows:
1. Four hundred and fifty three strains belonged to the 3 genera, Alginomonas (116 strains), Vibrio (5 strains) and Pseudomonas (332 strains).
2. One hundred and sixteen strains belonging to the genus Alginomonas were identified as A. fucicola (66 strains), A. nonfermentans (26 strains), A. alginovora (23 strains) or A. alginica (1 strain).
3. All the strains belonging to the genus Vibrio were identified as V. phytoplanktis.
4. Three hundred and twenty four strains among the 332 strains belonging to the genus Pseudomonas were identified as P. calcis or P. calciprecipitans and 8 strains could not be identified.抄録全体を表示PDF形式でダウンロード (466K) -

ジャーナル フリーThe distribution of proteolytic enzymes in the internal organs of octopus, Octopus vulgaris CUVIER, was investigated.
1. Proteolytic activities were detected in all the organs examined, though there were remarkable differences in the activities among the organs.
2. Proteolytic enzymes of such organs as liver, renal sac, heart, branchial heart and pancreas showed two optimum pH, near 2.5 and 6.0, for casein hydrolysis and the proteolytic activity of each organ was higher at pH 2.5 than at pH 6.0. The pancreatic enzyme scarcely hydrolyzed casein in the alkaline region. As for the activities of these organ enzymes, that of liver was the highest, followed by those of branchial heart, pancreas, renal sac, and heart in that order.
3. The anterior salivary gland and the submaxillary gland contained a proteolytic enzyme with optimum pH near 2.5. That of the former possessed the highest activity after the branchial heart enzyme.
4. The proteolytic activity of the posterior salivary gland was remarkably high in the alkaline region, which means that it possessed the highest activity of all the organs investigated. The pH optimum was near 8.5.
5. Proteolytic enzymes of digestive organs, such as crop, stomach, coecum and intestine, showed three optimum pH near 2.5, 6.0 and 7.5. They possessed only low activities, especially at alkaline pH.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The preventive effects of four tocol homologues on muscular dystrophy in young carp were compared with the casein-gelatin diet containing oxidized mackerel body oil. From the appearance of muscular dystrophy, growth, feed conversion, and histopathological observations it was concluded that α-tocopherol is far more effective than β-, γ-, and δ-tocopherols, in order of decreasing potency.抄録全体を表示PDF形式でダウンロード (2637K) -

ジャーナル フリーThe classification of bacteria isolated from the diet, environmental sea water and digestive tracts of red sea bream and file-fish fed in this laboratory was carried out, and isolated bacteria were divided into eight major groups (I-VIII). Only two subgroups, I-a1 and I-a11 in I group (genus Vibrio), were always dominant both in stomachs and intestines of red sea bream more than 6 hours after ingestion of diet, irrespective of the kind of diet (F-, S- or C-diet) given to fish, although within 6 hours after ingestion IV group (peritrichous rods) and VIII group (cocci) were present in the stomachs.
I group and VI group (genus Achomobacter) were present in the intestines of file-fish in relatively high ratios and the components of the flora reflected those of the diet. I-a1, and I-a11, dominatly present in the digestive tracts of red sea bream, were uniquely resistant to bile and low pH.
It is suggested that the indigenous flora of marine fish with developed digestive systems consists of specific Vibrio groups (I-a1 and I-a11).抄録全体を表示PDF形式でダウンロード (266K) -

ジャーナル フリーThe response of some representative strains of the indigenous and the other bacterial groups isolated from the digestive tracts of marine fish to the environmental conditions to be encountered in the stomach, i.e. low pH value and gastric juice, was examined. The results obtained are summarized as follows:
(1) In the cases of the indigenous bacterial groups (I-a1 and I-a11) and IV group, viability was not much influenced by 5 hour's incubation at pH 4.0; however, remarkable loss in viability was observed in the other groups under the same conditions. The turbidity of cell suspensions, in general, did not decrease markedly on incubation at pH 4.0.
(2) When gastric juice prepared from red sea bream was added to the pH 4.0 suspension, the viability of the strains of I-d and VI-b groups was significantly decreased after 5 hours' incubation. A marked decrease in turbidity was also observed with the strains of III, VI-b and VII groups, in the presence of gastric juice at pH 4.0. Pepsin, lysozyme and gastric juice from gizzard shad did not decrease the viability.
(3) The strains of the indigenous bacterial and VI-b groups grew well at pH 5.0, while the others did not grow under this condition.
These facts suggest that the indigenous bacterial groups (I-a1 and I-a11) are uniquely resistant or adapted to the environmental conditions in the stomach of marine fish.抄録全体を表示PDF形式でダウンロード (277K) -

ジャーナル フリーThe temperature dependence of the tensile stress relaxation behavior for kamaboko was studied. The results obtained were analysed as follows:
1) Kamaboko is a rubber-like slightly cross-linked material.
2) Kamaboko is thermo-rheologically simple.
3) The simple expression of WLF-form on the shift factor is not applicable in the temperature range of 45°C-65°C.抄録全体を表示PDF形式でダウンロード (190K) -
