ジャーナル フリーThe secretory granules of the corpuscular cells of STANNIUS and the renal juxtaglomerular cells (JG cells) were examined histologically, using five species of teleosts. The granules in the corpuscular cells are stainable by the BOWIE'S method which is used exculsively far the staining of JG cell granules. However, remarkable differences were detected in the staining of both kinds of granules when the following stains were used: GOMORI'S chrome-hematoxylin and phloxine, HEIDENHAIN'S iron-hematoxylin, and PAS stain. Therefore, it may be concluded that the JG cells and the corpuscles of STANNIUS, histologically speaking, are composed of different kinds of cells.抄録全体を表示PDF形式でダウンロード (1783K) -

ジャーナル フリーIn the present paper, the age and growth of butter fish, Psenopsis anomala (TEMMINK and SCHELEGEL), in the Kii Channel, are estimated based on size composition and on otoliths and ring marks on scales covered by the pectoral fin.
During the period from July in 1970 to April in 1972, 995 specimens were collected. Among those, scales from 510 specimens and otoliths from 203 specimens were observed and measured by a shadowgraph.
The results are summarized as follows:
1) The annual ring marks on scale are formed once a year in the spawning season from April to July.
2) The growth at the young stage is very rapid. However, the growth rate decreases when a length of about 130mm in body length is reached. This slowing down of growth rate is observed in autumn.
3) Since the change of the growth process in the early days, the growth equations for more than one age in length and weight are given as follows,
BLt=243.2{1-e-0.34(t+1.674)}, BWt=486.7{1-e-0.34(t+1.674)}2.8912
The body lengths at the age of 1-4 are calculated as 145.2, 173.5, 193.6 and 207.9mm respectively.抄録全体を表示PDF形式でダウンロード (1058K) -

ジャーナル フリーTo analyse the population of the jack mackerel, Trachurus japonicus, a total of 785 individuals, in 25 groups, were collected from 12 localities along the western coast of Kyushu. These specimens were examined for some blood elements and the electrophoretic pattern of plasma proteins. The ecological significance of the results obtained was then discussed from the fisheries point of view.
1. The specific gravity of blood, hematocrit value and the amount of plasma proteins were compared between the two groups of blood specimen. The one withdrawn from fish immediately after catch by angling, and the other withdrawn from the fish kept in a concrete tank for 56 days. All the obtained values in the latter group were higher than in the former. While, the electrophoretic patterns of plasma protein of the two groups were quite identical.
2. Electrophoretic patterns of plasma protein of the sepcimens kept in floating fish cages at several places in the northern part of Nagasaki Pref. were all the same. On the other hand, four different types were found in the fish collected from Goto-nada and the coast of Kagoshima Pref.
3. Although the correlation coefficient between the hematocrit value and the specific gravity of blood was as high as +0.92, the coefficient between the specific gravity of blood and the amount of plasma protein was +0.51, and that between the hematocrit value and the amount of plasma protein was +0.53.抄録全体を表示PDF形式でダウンロード (505K) -

ジャーナル フリーMishooking in skipjack troll fishing has continued to be a source of annoyance to fishermen. The authors carried out some investigations to know the causes for mishooking in skipjack trolling by using two types of generally used hooks and a new type of hook designed by the authors. Simultaneously, the effect of the improved hook with protections from mishooking were evaluated.
The results obtained were as follows.
1. The ratio of mishooked fish with the double hook was the greatest among the three kinds of hooks compared, and the smallest with the improved hook.
2. There was no difference in catch efficiency between the improved hook gear and quartet hook gear.抄録全体を表示PDF形式でダウンロード (398K) -

ジャーナル フリーThe carotenoid pigments from the fin and skin of horse mackerel, swellfishes, porcupinefishes and striped mullet were investigated. Tunaxanthin was predominant in horse mackerel (63-69%), swellfishes (33%) and porcupinefishes (56%). The following carotenoids were identified and their contents determined in the respective fishes: β-carotene(-, -, 4%), α-cryptoxanthin (2-trace, 3, 10%), cryptoxanthin (-, 10%, -), lutein(15-19, 3, 6%), zea1xanthin(10-16, 33, 16%), diatoxanthin(-, 7%, -), cynthiaxanthin(-, 8%, -), α-doradecin (-, 3, 1%) and astacene (-, trace, 1%), respectively.
Carangoxanthin originally reported in horse mackerel by Hirao was not detected in fishes collected at various seasons and places in spite of our detailed investigation.
In contrast with the above fishes, striped mullet contained zeaxanthin (68%) and lutein (20%) as the major carotenoids and a relatively small amount of tunaxanthin (6%).抄録全体を表示PDF形式でダウンロード (320K) -

ジャーナル フリーProperties of insolubilized protein formed by the reaction of lipid oxidation products such as propanal or caproic acid with rainbow trout actomyosin during storage at -20°C were studied in KCl-phosphate buffer (I=0.5, pH7.2).
These insolubilized proteins retained nearly the same amino acid compositions, but tended to be harder, more elastic and more digestible. In addition, the net-work grade in electron photomicrographs became slender and close. These effects were stronger in the caproic acid addition system than in the propanal addition system. It was considered that the differences in those effects were due to the various progressive degrees of the intra- and/or intermolecular reactions of the proteins, and that these reaction degrees were attributable to propanal and caproic acid having different interaction mechanisms.抄録全体を表示PDF形式でダウンロード (912K) -

ジャーナル フリーThe interaction mechanism of lipid oxidation products, such as propanal or caproic acid, with rainbow trout actomyosin (AM) was studied in KCl-phosphate buffer (I=0.5, pH7.2) during storage at -20°C.
From the results obtained in the present and the previous studies, the mechanism was hypothesized to be as follows:
During storage, AM aggregation and consequent insolubilization occurs, mainly due to intra and intermolecular S-S bonding.
Propanal forms mercaptal by reacting with SH groups which appear on the unfolding AM molecule during the initial stage of frozen storage, and thereby accelerates the AM insolubilization.
Caproic acid, bound to AM with hydrogen and/or hydrophobic bonds, unbalances the net-charge of the AM molecule thus inducing the insolubilization of the protein.抄録全体を表示PDF形式でダウンロード (261K) -

ジャーナル フリーIt has been demonstrated that protein digestive enzymes in the digestive tract of octopus, Octopus vulgarts CUVIER, are mainly secreted by the liver and pancreas. In the previous paper, the author suggested that the posterior salivary gland enzyme plays an important part in protein digestion. In order to confirm whether the protein digestive enzyme originates in the posterior salivary gland or not, a few experiments were carried out using an octopus which had undergone an operation to stop the saliva secretion from the gland.
The results may be summarized as follows: there are remarkable differences between the experimental group and the control group in (a) the state of dietary protein remaining in digestive tracts, (b) the proteolytic activity of digestive juices and (c) the proteolytic activity of posterior salivary gland extracts.
From the results described above, it is evident that the greater number of protein digestive enzymes in the digestive tract originate from the posterior salivary gland and largely contribute to digestion.抄録全体を表示PDF形式でダウンロード (935K) -

ジャーナル フリーIn the previous paper, it was shown that the greater number of protein digestive enzymes in the digestive tract originate from the posterior salivary gland. The present paper deals with isolation and purification of proteolytic enzymes from the gland.
Results obtained are summarized as follows: a crude extract was obtained with 1% NaCl solution from the tissues and subjected to gel filtration of Sephadex G-75. From proteolytic enzyme fraction obtained by the gel filtration, seven proteolytic enzymes and carboxypeptidase A like enzyme (CPA like enzyme) were separated by ion-exchange chromatography on CM-Sephadex C-50. Three of the seven enzymes obtained were electrophoretically homogeneous and hydrolyzed casein strongly at near pH 7. On the other hand, CPA like enzyme, when further purified by the ion-exchange rechromatography, was also found to be electrophoretically homogeneous.抄録全体を表示PDF形式でダウンロード (891K) -

ジャーナル フリーThe purpose of this study was to elucidate the lipid components of marine benthic algae: i.e., one species of green, nine of brown and seven of red algae. For comparative purposes, more highly evolved plants, i.e. one fresh water stonewort and two phanerogams, one marine and one terrestrial type, were also analyzed. The component fatty acids in the acetone-soluble fractions were analyzed by gas-liquid chromatography.
The brown and red algae both contained high proportions of 20:4 and 20:5 fatty acids while both green and brown algae were distinguished by high contents of 18:3 and 18:4 acids. A high proportion of the component fatty acids in green algae consisted of C18-and C16-acids, in brown algae of C18-and C20-acids and in red algae of C16-and C20-acids.
While there were significant differences among the component fatty acid patterns of the acetone-soluble lipids of green, brown and red algae, the green algae pattern particularly showed a close resemblance to the stonewort and phanerogam patterns.抄録全体を表示PDF形式でダウンロード (563K) -

ジャーナル フリーCarotenoid pigments in two species of lobsters, Scyllarides squamosus (=Scyllarus sieboldi) (I) and Parribacus antarcticus (=p. ursus-major) (II), were analyzed and the results were compared with those of Panulirus japonicus (III) reported in a previous paper. The carapace of I, II and III were almost similar in carotenoid content, astaxanthin comprising nearly half of the total content with such carotenoids as β-carotene, echinenone, canthaxanthin, phoenicoxanthin, lutein and zeaxanthin being relatively minor. However, I and III which are taxonomically closely related species also contained 4-keto-zeaxanthin and cynthiaxanthin, which accounted for about 30% and 10% of the total carotenoid content respectively (4-keto-zeaxanthin=30%; cynthiaxanthin=10%), while II entirely lacked both pigments.
In the eggs, the carotenoids were found only in the free form and their carotenoid patterns were similar to those in the carapace of the respective species examined. In I and III, the main carotenoid was astaxanthin which comprised about 40% of the total while in II, it was β-carotene (40%). β-carotene was the dominant carotenoid in the hepatopancreas of I, II and III, comprising 80 to 90% of the total. 4-Keto-zeaxanthin was identified in I and III in spite of the fact that its occurrence in crustacea has never been reported, possibly because its separation from astaxanthin during analysis is difficult.抄録全体を表示PDF形式でダウンロード (272K) -

ジャーナル フリーThe results of examination at subzerotemperatures in supercooling of the growth or viability and TMAO reducing activity of some psychrotrophic bacteria isolated from fresh fish indicate that the minimum growth temperature is -4 to -5°C and that, generally, there is no increase in bacterial cells nor any TMAO reducing activity at -4°C during 25-day storage when the initial cell counts are 106/ml, although reduction of TMAO does occur when the initial cell counts are 108/ml.抄録全体を表示PDF形式でダウンロード (308K) -
