ジャーナル フリー“Hamachi” culture has been rapidly developing in recent years. But it is considered that there is much room for further research, especially, into feedstuff and technical manage-ment. Needless to say, blood properties are connected with the physiological conditions. From July 1961 to Feb. 1962 the authors investigated the seasonal variations of serum protein, phosphorus, calcium, cholesterol and alkaline phosphatase contents in the blood of cultured “Hamachi”. The results obtained are as shown in Table 2 and Fig. 2-7.
(1) From spring to summer, the contents of these constituents increased with the speedy growth of the fish. Subsquently, the contents began to decline with the drop of water tem-perature, with the exception of cholesterol contents which rather increased in winter after a temporary decrease in autumn.
(2) In winter, the value of “Free cholesterol content/Total cholesterol content” and “Inorganic phosphorus content/Total phosphorus content” slightly rose and dropped respec-tively.
(3) The coefficients of variance of the contents of each constituents did not show the similar seasonal change but those of alkaline phosphatase and free cholesterol contents were generally high and low in calcium.
(4) In such excessive culture as three times number above normal, the individual difference became larger and serum protein and total phosphorus contents were lower and the value of “Inorganic phosphorus content/Total phosphorus content” was extremely higher compared with those of moderate.抄録全体を表示PDF形式でダウンロード (421K) -

ジャーナル フリー1. The diurnal fluctuation of carbon dioxide content of water in eel-culture-ponds was studied by means of the diffusion analysis method.
2. Total CO2, HCO3- as well as H2CO3 (dissolved gas of carbon dioxide plus free car-bonic acid) were found to decrease in the daytime and to increase in the nighttime. Their minimum figure was observed in the afternoon at the time when O2 was at its maximum, and the maximum one was observed early in the morning at the time when O2 was at its minimum. The fluctuation of CO3- content was contrary to that of other forms. (Fig. 1-3.)
3.The range of the diurnal fluctuation of carbon dioxide content was proportional to the density of phytoplankton, the density of fish, the total amount of solar radiation, and the tem-perature of water. (Table 1.)
4. H2CO3 content of the water ranged from 0.003 to 0.821 mEq./l early in the morning at its maximum. These values were considered not to cause the surfacing of eels which is a sign of dyspnoea. (Table 2.)
5. Total CO2 content of the water ranged from 0.11 to 3.58mEq./l in the afternoon at its minimum. (Table 2.)抄録全体を表示PDF形式でダウンロード (475K) -

ジャーナル フリーOn the basis of questionnaire returned from about 30 fishing boats which operated for the saury (Cololabis saira) off Northeastern Region in 1950 and 1951, relationship between catch per boat-day and technical factors for fishing such as size of boat, and efficiency of equipments was analyzed. Since saury lift netters are engaged in other types of fishery during the offseason, boat-day catch among competing fishing units may as well be affected by fishermen's economic dependency based on annual income for each fishing boat was inquired of, and made available by, fishermen who cooperated in the survey.
The study indicated that factors which had a positive correlation with the boat-day catch were the size of boat in term of gross tonnage, economic dependency, powers of fishing light and search light, and size of net (Tables 1 to 3 and Figs. 1, 2).
The questionnaire returned revealed that the boat-day catch had a positive correlation with two items out of seven means the fishermen relayed on in choosing a fishing ground for every trip. They were combinations of items 1 and 5, radio broadcast of fishing conditions and data of current and water temperature provided by local service agencies, respectively (Figs. 3 to 5).
In locationg a school of fish, advantageous combinations among six technical items inquired of the fishermen were: 2) use of fish finder, 4) detecting an area with a favorable water temperature for the fish, and 5) search for water boundary (Figs. 6 to 8). The results suggest that those boats which combined relatively new kinds of information and more advanced technical means for their use seem to have had a higher catch per boat-day than their fellow fishing boats.抄録全体を表示PDF形式でダウンロード (274K) -

ジャーナル フリーThe digestibilities of protein and starch in the diets containing different levels of these nutrients were determined by the indirect method using Cr2O3 as an indicator. The fish used were rainbow trout. The results obtained are summarized in Table I. The digestibilities of protein and α-starch (cooked) varied with the contents of these nutrients in diet. The digestibility of protein was high when the diet contained relatively high levels of protein. Whereas, the digestibility of α-starch showed high value when the diet contained relatively low levels of starch. As the content of starch in diet increased, the digestibility decreased. A β-starch (raw) was considerably low in digestibility.抄録全体を表示PDF形式でダウンロード (204K) -

ジャーナル フリーA study of the hooked rates of tuna species in relation to live and frozen bait, and frozen baits of different species was made. Most cases showed slight differences in the hooked rate and very few cases were significantly different. As a result it was not possible to state that there is no food preference among tunas and that it does not have any influence on the hooked rate. However, the variability of tuna catches made with the longline gear is so very large that the effect of the bait preference shown by tunas on the catch may be relatively negligible. Cost and availability of bait species appears to be the aspect to be considered in choosing effective tuna longline bait for commercial or even exploratory purposes.抄録全体を表示PDF形式でダウンロード (338K) -

ジャーナル フリーIn studying how to improve the nature of wheat starch used in “Kamaboko”, a fish meat jelly product, it was found that the gelatinization temperature of wheat starch, when lecithin added, became lower.
Also the following were observed:
1. Wheat starch, when lecithin added, produced a jelly of higher strength at a lower temperature.
2. A higher jelly strength was obtained when “Kamaboko” was from wheat starch containing lecithin and fish meat at a low heating temperature. Especiall when lecithin was added to wheat starch at a rate of 0.1-0.5%, it was most effective.
3. Since lecithin has no action on potato starch, no difference was seen between “Kamaboko” made from lecithin-added potato starch and that from non-lecithin potato starch.抄録全体を表示PDF形式でダウンロード (428K) -

ジャーナル フリーOctopus is well known as incriminated materials of food poisoning. There are many investigations on the food poisoning caused by octopus and concerned problems. Recently halophilic bacteria, Pseudomonas, have been found very often as pathogenic one in food poisoning caused by octopus.
The author had the chance to inspect octopus caused food poisoning in 1956, and found its 80% methanolic extracts had lethal effect on mice (Table 2). This poisonous substance was supposed to be produced by bacterial action. From the results of partition paper chro-matography using buthanol, acetic acid and water (4:1:2) as developing agent, it was found that the toxic substance separated into two toxic spots, Rƒ value of 0.13 and 0.32, of which the former one was lethal and the latter one was less toxic (Figs. 1 and 2; Table 3).抄録全体を表示PDF形式でダウンロード (223K) -

ジャーナル フリーThe proceeding paper considered that the food poisoning by octopus was caused by poisonous substance produced by bacterial action. MIURA et al2) reported previously that the food poisoning by fresh water shrimp, Paratya compressa (improvisa Kemp), was supposed to be induced by the toxic substance produced by a strain of Proteus. This shrimp food poisoning occured in the near place of food poisoning by octopus.
Hereupon author isolated some bacteria (Table 1, Fig. 1) from the fresh water shrimp caught in this area and studied to know whether a strain of these bacteria (thought belong to the same group as the isolated by MIURA et al), toxicate octopus or not.
The results obtained are as follows:
(1) Toxic substance is producible on octopus or its 80% methanol extracts by the action of Rettgerella like bacteria (Table 3).
(2) Toxic substance is extractable by water and 80% methanol.抄録全体を表示PDF形式でダウンロード (1114K) -

ジャーナル フリーWhen a ferric chloride reagent was impure for colorimetric determination of cholesterol, the working line did not pass on its original point and thus had to be corrected suitably for the determination. This correction has been achieved by addition of hydrosulfite to the reagent without further purification. One milligram of hydrosulfite was added as a 15% water solution to 1 cc of the reagent. The reagent was found ready for use as a color reagent by keeping it for one day at 25° and also found stable at least for six days after the preparation. Whereas a reagent, if unstabilized, sometimes yields a turbid solution in the color reaction to render colorimetric measurement impossible.
The time required to develop the maximum absorbancy of a color reaction mixture varies depending on preparations and therefore must be examined before drawing a working line.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 characteristics of the acetone-soluble lipid contained in “TOGGOTOMEBARU”, Sebastodes joyneri, were studied. The lipid contained in ten fresh sample fish was extracted with acetone immediately after catch. The acetone-soluble lipid was obtained in the yield of 2.24% from the fresh fish. The lipid had the characteristcs as given in Table 2.
The mixed fatty acids, prepared from the acetone-soluble lipid by alkali-hydrolysis, were separated into three portions, solid, unsaturated and highly unsaturated acids, with a combination of lead salt-ethanol and lithium salt-acetone methods and their methyl esters were fractionated as usual through the modified E.H.P. column.
According to calculation of HILDITCH, the component fatty acids of the acetone-soluble lipid are shown in Table 7. The paper chromatography indicated the presence of myristic, palmitic, stearic, arachidic, zoomaric, oleic, linoleic and linolenic acids.抄録全体を表示PDF形式でダウンロード (1034K) -
