ジャーナル フリーOver 400 specimens of Mustelus manazo were collected from Choshi to study its age, growth, reproduction, and food habits. Annuli were estimated to occur on vertebral centra yearly from analysis of monthly marginal growth ratios. linear relations were obtained between radius of centrum and total body length. Von Bertalanffy growth equations are described as follows; male: lt=1043[1-exp{-0.19(t+2.00)}]: famale: lt=2771[1-exp{-0.032(t+4.77)}]. Both males and females reached their first maturity at 621-640mm and all the specimens over 700mm attained their maturity. However, age determination suggests that females reached maturity at a little older age than males. Monthly gonad indices of males show that copulation occurred between June and July. Gestation period is estimated to be approximately 10 months. Litter size ranged from 1 to 22 with an average of 4.9, although litter size increased with the length of the parent. Stomach content analysis shows that Crustacea were the most important prey animals with 85% occurrence. Among others, percentage occurrence of crabs exceeded 50%. Fishes composed chiefly of sardine were also important food items as well as Polychaeta and Spinculoidea.抄録全体を表示PDF形式でダウンロード (596K) -

ジャーナル フリーJapanese eels Anguilla japonica. 2g in average body weight, were raised for 22 days in 16 l-tanks with continuous supply of freshwater of 25plusmn;1°C with various dissolved oxygen concentrations, in order to obtain the lowest limit of dissolved oxygen concentration above which normal values for growth rate, feed efficiency and feeding rate could be maintained.
Oxygen concentration was controled by introuducing nitrogen gas in a reservoir of inflowing water.
The growth rate, feed effciency and feeding rate in each experiment were represented by the relative value.
The relative growth rate and the relative feed efficiency were kept almost constant above the oxygen concentration of about 4.5 mg/l and decreased remarkably below that level. The relative feeding rate began to decrease below the oxygen concentration of 4.0mg/l.
The occurrence of high mortality at the oxygen concentration of about 1.0 mg/l suggests that oxygen deficiency at this level is fatal to the fish.
From these results, it is concluded that the critical level of dissolved oxygen concentration for the normal growth of eel weighing about 2g must be about 4.5mg/l (54% saturation) at 25plusmn;1°C.抄録全体を表示PDF形式でダウンロード (331K) -

ジャーナル フリーTo obtain neccessary information about the infection mechanisms of edwardsiellosis in eel, variation in the number of pathogenic bacterial cells released from the diseased eel was investigated. Eel were injected with Edwardsiella tarda intramuscularly and kept individually in aquaria incubated at 20°C, 25°C and 30°C respectively. Two sets of aquaria were prepared at specified temperature. Dead eel were taken off from one set while they were left in the other set.
The number of released cells reached almost the same level ranging from 105 to 106 cells/ml at the three temperatures in common, but the increase in the number of cells was faster at higher temperature than at lower temperature. The number of cells increased very much in aquaria in which dead eel were left, and reached about 1, 000 times as many as that in aquaria from which dead eel were taken off. The level of the number was maintained throughout the experimental period of 21 days.
From these results, it is confirmed that diseased eel release a great number of pathogenic becteria, consequently the infection would spread throughout the pond if diseased eel are not taken off.抄録全体を表示PDF形式でダウンロード (377K) -

ジャーナル フリーAs a part of reasearch on introduction of lobster Homarus americanus into Japan, a preparatory release was achieved in Koshiki Islands near Kyushu in July 1982. Before releasing, 100 concrete blocks were laid on sandy bottom in 4 parallel lines with a 2m space between each block. 97 one year old lobsters (XI-XV stage) were introduced under each block one by one. Monitoring was carried out for 11 days by diving. Survival rate was 2.7% and 25.0% for the lobsters released close to the stony-coral substrate and the others respectively. Movement of lobsters between blocks was rather frequent. Roughly 20-40% lobsters disappeared and 10-15% new ones appeared under the blocks. These facts suggest that the number of lobsters decreased mainly due to aggression by fishes which inhabit the stony-coral substrate.
A net cage (3m×3m×hight 0.3m) without bottom was immersed into the sandy substrate for another experiment. About 500 oyster shells were placed inside the cage. 156 three week old lobsters (IV-V stage) were released into the cage. Survival rate was 68% just after release and 25% agter 9 days. Degree of movement for IV or V stage lobsters was rather similar to that of one year old lobsters.抄録全体を表示PDF形式でダウンロード (516K) -

ジャーナル フリーExperiments were conducted to find out dietary lipids suitable as the practical feed of Tilapia nilotica, feeding them with the diets containing corn oil, soybean oil, pollock liver oil, beef tallow and medium chain triglyceride (MCT), respectively.
The best weight gain and feed effciency were obtained in the fish receiving corn oil or soybean oil, both rich in 18: 2ω6. When corn oil was replaced by pollock liver oil, the growth rate was significantly decreased, indicating that pollock liver oil has no growth enhancing effect for the fish. The growth rate of fish, fed on the diet containing beef tallow or MCT as a basallipid, was inferior to that of the fish receiving 18: 1ω9, suggesting that the saturated fatty acids with carbon number 8 to 18 are not suitable for the basal lipid in diet of Tilapia nilotica.
Feeding the diet containing 18: 1ω9 or beef tallow resulted in raising the level of 20: 3ω9 and an ω9 fatty acid with carbon number 22. Both corn oil and soybean oil were found to be more effective than pollock liver oil in reducing these levels.
Thus, the dietary lipid suitable for Tilapia nilotica was found to be vagetable oils rich in 18: 2ω6 such as corn oil and soybean oil, and pollock liver oil had no dietary value for the fish unlike the other fish species.抄録全体を表示PDF形式でダウンロード (292K) -

ジャーナル フリーIn order to clarify a reason for which carboxymethylcellulose (CMC) increases the growth of red sea bream Chysophrys major and feed efficiency, the effects of CMC supplement on the absorptions of dietary dextrin and protein, and on the levels of blood sugar and plasma amino nitrogen were studied. CMC supplement into diets delayed the absorptions of dextrin and protein, and suppressed the elevation of blood sugar and plasma amino nitrogen levels within 2 hours after the feeding. From these results, it is presumed that the dietary dextrin and protein are effectively utilized by the supplementation of CMC as the energy source and for the biosynthesis of body components, consequently the growth of red sea bream and feed effciency are improved.抄録全体を表示PDF形式でダウンロード (211K) -

ジャーナル フリーThe coelomic fluid of Balanus balanoides was found to agglutinate mouse keukemia cell L5178Y and a marine bacterium Vibrio sp. in addition to various kind of animal erythrocytes. It stimulated the phagocytosis of rabbit erythrocytes by mouse macrophage. The agglutinin was purified and found to be a glycoprotein having a molecular weight of 330, 000 daltons. It contained three different subunits. The main subunits had a molecular weight of 70, 000 daltons. Isoelectro-focusing gave two bands; the main band at pI 4.7 and the minor one at pI 5.3. The hemag-glutinating activity of the purified agglutinin was inhibited by D-galacturonic acid, D-glucuronic acid and N-acetylneuraminic acid. The glycoprotein contained high amount of aspartic acid and glutamic acid, and little histidine. There was no preasence of half cystine and arginine.抄録全体を表示PDF形式でダウンロード (571K) -

ジャーナル フリーFeeding experiment was conducted for 6 weeks to clarify effects of supplemental electrolyte and/or dietary pH on utilization of an amino acid diet using fingerling carp. Growth and feed effciency improved without noticeable effect on feed consumption as the dietary pH was raised from 4.6 to 5.2 or 5.8 together with rise in Na level from 0.13% to 1.23% or 1.73%, due to substitutions of Asp and Glu with Na•Asp and Na•Glu, respectively. Also change in the dietary pH alone showed the similar effects on the growth and feed effciency when pH of the diet was lwered from 4.9 to 4.5 by addition of acetic acid, where Asn and Gln were used instead of Asp and Glu to raise the original dietary pH to about 6. When the dietary pH were kept at 5.7-5.9 levels with use of Asn and Gln instead of Asp and Glu, supplement of K (1.41%) as acetate form up to equimolar level of Cl from supplemented Arg•HCl and Lys•HCl resulted in better growth and feed efficiency than that of Na (0.70%). However, excess supplements of K (2.30%) and Na (1.23%) depressed growth and feed effciency almost to half in the former and only slightly in the latter with significantly elevated feed consumption in both cases. Rise in the dietary pH level alone or combination with increment in Na level resulted in the decline of moisture with increased fat content as well as fall in Na, K and ash contents in the whole body of fish sampled at the end of the experiment. However, almost completely opposite results were obtained when Na or K level was raised with little change in the dietary pH.抄録全体を表示PDF形式でダウンロード (295K) -

ジャーナル フリーFeeding experiments were carried out to examine the supplemental effect of crystalline amino acids to casein diets on the growth of cherry salmon Oncorhynchus masou and amago salmon O. rhodurs fry. The essential amino acid patterns of eyed egg and whole body protein of cherry salmon were used as references. The following four diets were given to both groups for six weeks; a casein diet without crystalline amino acid (Diet 1), a casein diet supplemented with crystalline amino acids to simulate the essential amino acid ratio (A/E ratio) of the eyed egg protein (Diet 2), a casein diet supplemented with crystalline amino acids to simulate the A/E ratio of the whole body protein (Diet 3), and a white fish meal diet (Diet 4). Both species showed essentially the same responses to the dietary treatments and their growth responses were as follows Diet 3>Diet 2>Diet 1>Diet 4. The groups fed on Diet 3 showed significantly higher daily growth rates than those fed on Diet 1, whereas daily growth rates between Diet 2 group and Diet 1 group were not significantly different. The highest feed effciency and protein effciency ratio were obtained in the groups fed on Diet 3. Fishes fed on Diet 4 showed the highest daily feed consumption rates, but the daily growth rates and the feed effciencies were the poorest compared to all the other dietary groups.抄録全体を表示PDF形式でダウンロード (362K) -

ジャーナル フリーThe upper stream, midstream and downstream of the Tama River were chosen as stations 1, 2, and 3, and water quality and bacterial flora in the gastrointestinal tracts of fishes, water, sediment, aquatic insects and aquatic plants were bimonthly examined by using 10 different agar media under aerobic and anaerobic conditions.
In the gastrointestinal contents of the fresheater fishes, facultative anaerobes, Enterobac teriaceae and Vibrio-Aeromonas group were always predomint but obligate anaerobes, Bacteroides type A and Bacteroides type B failed to be isolated from all fish samples. Vibro-Aeromonas group, Bacteroides type A and Bfailed type B which are known to be major components in the gastrointestinal tracts of cultured freshwater fishes; these were isolated from water, sediment and aquatic plants, so the bacteria in the gastrointestine of fishes in the natural waters are suspected to originate from the environment.
In the water and sediment, log number of total viable counts was found to correlate with concentrations of COD. The relationship between vaible counts in each bacterial components and total viable counts in each habitat was discussed using the regression equatin.抄録全体を表示PDF形式でダウンロード (587K) -

ジャーナル フリーEnzymatic hydrolysis of phospholipids in cod flesh during storage at -16°C for 24 weeks were studied. The contents of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) decreased rapidly during storage for up to 11 weeks and then slowly. During storage for 24 weeks, 72.5% of PC and 52.2% of PE were hydrolyzed: pc was hydrolyzed faster than PE. Contrary to this, the content of free fatty acid increased rapidly during storage for up to 11 weeks and then slowly.
Major PC in the cod flesh were those having fatty acid combinations of (C16, C22), (C16, C20), (C18, C22), (C18, C20), (C20, C22), and (C16, C18). Percentages of PC having the combinations of (C16, C22), (C20, C22), (C16, C18), and (C22, C22) increased slightly during storage, while those of (C16, C20) and (C18, C20) decreased. In the case of PE, major fatty acid combinations were those of (C18, C22), (C16, C22), (C20, C22), (C22, C22), (C20, C20), (C18, C20), and (C22, C22) During storage, percentages of PE having the combinations of (C18, C18) and (C22, C22) increased slightly, while toshe of (C18, C22), and (C20, C22) decreased.
From these results, it was presumed that the PC and Pe having certain fatty acid combinations in cod flesh are hydrolyzed preferentially by lipolytic enzymes during cold storage.抄録全体を表示PDF形式でダウンロード (536K) -

ジャーナル フリーThe lipids of cultured sea bream was analyzed by GLC and HPLC and compared with that of wild sea bream. The results obtained are as follows: (1) the lopid content of cultured sea bream is higher than that of the wild one. (2) In the fatty acid composition of non-polar lipid, percentages of C14:0, C18:8, C20:5, and C22:6 in cultured fish are higher than those in the wild one, while percentages of C16:1, C18:0, and C18:1 lower. (3) In the fatty acid composition of phosphatidylcholine, percentage of C22:6 in cultured fish is higher than that in the in the wild one, while percentages of C16:1, C20:4, C20:5, C22:4, and C22:5 lower. (4) In the case of phosphatidylethanolamine, percentages of C18:0 in cultured fish is higher than those in the wild one, while percentages of C20:4, C20:5, C22:4, and C22:5 lower.
In addition, some differences in the triglyceride compositions based on the total acyl carbon and partition number were found between cultured and wild sea breams.抄録全体を表示PDF形式でダウンロード (281K) -

ジャーナル フリーAs a part of investigation to explore useful constituents of plankton, we have taken up carotenoid pigments of the Antarctic krill Euphausia superba and analyzed their composition, The content of carotenoids in the frozen krill was determined to be 3-4mg/100g. The carotenoids comprised astaxanthin diester (I), astaxanthin monoester (II), astaxanthin (III), and unidentified ones (IV) in 40-50%, 30-40%, 15-25%, and 5-15%, respectively. In the case of the krill meal, the conten was 15-20mg/100g and the composition of I, II, and IV was 65-75%, 15-25%, and 5-15%, respctively, lacking III. Two kinds of unique colored carotenoids of dense crimson and of violet occupied the major part of IV. Both were supposed t be esters of retro carotenoids.抄録全体を表示PDF形式でダウンロード (333K) -

ジャーナル フリーThe stability t heat and solvent of carotenoids in the Antarctic krill Euphausia superba was examined. When homogenates of the frozen krill were heated at 100°C, little change was noticed up to 1 hour in the content and composition of the carotenoids. After 3 hours of heating, however, the content decreased to less than half and the composition changed into 78% of astaxanthin diester (I) and 21% of astaxanthin monoester (II) with almost complete disappearance of astaxan thin (III) and unidentified carotenoids. As the stability test to solvent, purified I, II, and III were stored in four kinds of solvents, benzent, hexane, acetone, and ethanol, in darkness, at 15°, 0°, and -20°C up to 2 weeks and analyzed for the retained carotenoid. In tbenzene and hexane, I was the most stable without noticeable decomposition. II showed less stable tendencies and III was rather unstable especially in hexane above 0°C. In acetone and ethanol, even I was remarkably decomposed at 15°C. As whole, it was concluded that I was the most stable to heat and solvent.抄録全体を表示PDF形式でダウンロード (296K) -

ジャーナル フリーMicroencapsulated digestive enzymes were supplemented in various combinations and levels in diets for the shrimp Penaeus japonicus based on digestive enzyme activities of live short-necked clam Venerupis philippinarum. The effects of these digestive enzyme additives on growth, feed efficiency, hepatopancreatic glycogen, and digestive enzyme aotivities were investigatred.
Dietary supplements of α-amylase at levels comparable to those of live short-necked clam enhanced the growth and reduced the glycogen storage. However, an α-amylase supplement, at a level three times that found in clam, in combinatin with bovine trypsin, equal in levels to shortnecked clam, enhanced the growth but also increased the hepatopancreatic glycogen, as did a diet supplemented with bovine trypsin alone, A diet supplemented with amylase at a level two times that of cam, enhanced the growth without increasing the hepatopancreatic glycogen. Bovine trypsin dietary supplements may have activated the endogenous protease zymogen (s) of the shrimp, resulting in increased growht and total protease activities.抄録全体を表示PDF形式でダウンロード (1302K) -

ジャーナル フリーEffect of preservation temperature on the quality of defrosted surimi of Alaska pollack was studied as a function of time. For the quality determination of surimi, the hardness of kamaboko gel prepared by grinding surimi with 3% salt and cooking, and also some biochemical properties of myofibrils in the surimi were used.
When surimi kept at an even temperature in the range of 2-35°C, logarithm of hardness of gel vs storage time gave straight lines, indicating that thermal deterioration for gel forming ability of surimi followed first order kinetics. The apparent rate constants (kj×10-5s-1) were then ca'culated as 0.14 at 2°C, 0.4 at 10°C, 1.3 at 20°C, and 28 at 30°C, respectively. A comparison of KJ to the other fish species showed that gel forming ability of the surimi was rapidly lost in the order of Alaska pollack, white croaker, and tilapia from the best to the worst in the descending order.
At above 25°C, changes in ATP ase activity, contractibility, and solubility for myofibrils in surimi during preservation were similar to that in the hardness of kamaboko gel prepared from the same material. However, at lower temperatures (2°-20°C), the gel forming ability of surimi deteriorated rapidly than all the biochemical properties of myofibrils.抄録全体を表示PDF形式でダウンロード (662K) -

ジャーナル フリーAn experimental feeding trial was conducted with rainbow trout to compare the nutritive value of five commercially avaiable soybean meals (puffed full-fat soybean, toasted full-fat soybean, hexane extracted soybean, extruded hexane extracted soybean and alcohol extracted soybean) as a partial replacement for Peruvian fish meal in a practical ration. The dietary level of Peruvian fish meal was reduced from 35% to 10% and the level of soybean meal increased from 0% to 50%, replacing up to 75% of the Peruvian fish meal protein, with no adverse effects on overall growth performance or feed utilizatin efficiency. There was no apparent difference between treatments on the basis of the five soybean meals tested. The results are discussed in the light of possible anti-nutritional factors present within soybean.抄録全体を表示PDF形式でダウンロード (453K) -

ジャーナル フリーThe ability of photosynthetic diatoms to utilze organic nitrogenous substances in the light was investigated to clarify the physiological characteristics of phytoplankton which was employed as the biological indicator organisms in the eutrophic level as proposed by the authors.
Skeletonema costatum collected at Dokai Bay and ranked as an indicator species of extremely eutroohic level was able to use peptone, trypticase, and urea. Further this species was capable of using several amino acids among twenty two amino acids tested. In this species, arginine and glutamine were excellent nitrogen sources as well as nitrate, followed by glutamate, aspartic acid, and tryptophan in somewhat low order. On the other hand, three indicator organisms ranked as eutrophic species such as S. costatum collected at Suho Nada, and Chaetoceros curvisetus and Eucampia zoodiacus could scarcely utilize organic nitrogenous compounds except urea, as a sole nitrogen source.
The heterotrophic capability of S. costatum which ranked as an extremely eutrophic species appears t be an important factor towards growth under an environmental condition polluted by domestic and industrial effluents.抄録全体を表示PDF形式でダウンロード (332K) -

ジャーナル フリーMuscular protein was freshly extracted with media containing high salt concentrations of I=0.5-1.0 from Antarctic krill Euphausia superba immediately after being caught.
The molecular composition of the extracted protein was roughly discussed by Sepharose C1-4B gel filtration. SDS-gel electrophoretic pattern, viscosity and ATPase activity were also measured to characterize the protein component in the extract.
By gel filtration, the extracted protein with I=0.5 as well as I=1.0 media was separated into three protein fractions: A, b and C in order of molecular size from the large to the small. In addition to SDS-gel electrophoretic patterns of the three fractions, viscosity and ATPase activity of the extracted protein proved that the A and B fractions were composed of actomyosin with different molecular size. A large portion of the C fraction was found to be water soluble protein component which were extractable with medium of I=0.05.
The amout of the components in B fraction decreased with the increase in the component of A fraction during storage for a short period or washing-treatment of muscle.抄録全体を表示PDF形式でダウンロード (2357K) -

ジャーナル フリーThe fatty acid composition of total lipids extracted from the muscles and viscera of wild and cultured ayu (sweet smelt), caught monthly from May to November, was investigated.
It was noticed that the content of C15:0, C17:1, C18:3, C20:5, and C22:5 was higher in the lipids of wild ayu, and that of C18:1 and C18:2 in the cultured ayu. The composition of fatty acids differed slightly during the maturation period after summer; but the decrease of C14:0 and C16:1 and the increase of C20:5 and C22:6 in the viscera of wild ayu were remarkable.
The lipids of wild and cultured ayu seemed to be affected by those of sessile algae and commercial diet, respectively.抄録全体を表示PDF形式でダウンロード (349K) -

ジャーナル フリーThe incorporation of two precursors, [1-14C] palmitic acid and [(U)-14C] L-glycerol-3-phosphate, into the lipid classes by the carp intestinal preparation was investigated in order to clarify the metabolic pathway of triglyceride and phospholipid biosyntheses. It was found that the precursors were incorporated into triglyceride and phospholipid via intermediate phosphatidic acid and diglyceride in the intestine of carp.
The effect of the oxidized lipids on the incorporation of the precursors into the lipid classes by the carp intestinal preparation was examined. The oxidized lipids did not affect the conversion of glycerol-3-phosphate into phosphatidic acid, but they would inhibit drastically the biosynthetic pathway of diglyceride and triglyceride via phosphatidic acid.抄録全体を表示PDF形式でダウンロード (401K) -
