ジャーナル フリーThe number of creatures remaining in a pot may be closely related to the pot construc-tion and the degree of interaction between the captured individuals in the pot, influenced by its passive catching function. We examined aspects of escape and capture of Macrobra-chium nipponense in small prawn pots under actual fishing conditions. The number of in-dividuals in a pot changed in an oscillatory pattern. The entry and escape of small prawns was an important factor in daily variations in the number remaining in a pot. There was no difference in the mean values of animals remaining obtained under different conditions. There was a similarity between the period for a peak catch in the experimental results and findings from actual operations.抄録全体を表示PDF形式でダウンロード (457K) -

ジャーナル フリーThe burying ability and grain size selection of hatchery-reared marbled sole and Japanese flounder juveniles were studied using sand of various grain sizes.
Sand obtained from fishing areas were categorized into six grain-sizes: ?? 0.125mm, 0.125 ?? 0.25mm, 0.25 ?? 0.5mm, 0.50 ?? 1.0mm, 1.0 ?? 2.0mm and 2.0 ?? 2.83mm. The buried area was visually measured. Marbled sole juveniles from all three size groups (The means of the total lengths were 35.0, 58.7 and 80.6mm.) were able to bury themselves in sand consisting of grains smaller than 1mm in diameter. However, in sand with a diameter larger than 1mm, only the 80.6mm group was able to bury themselves. Thus, the burying ability increased with growth.
Sands of two different grain sizes were laid on both halves of the bottom of the container. Marbled sole (35.0mm TL) and flounder (55.7mm TL) preferred medium grain sizes, 0.125 ?? 0.5mm in diameter. A positive correlation between the preference index and the buried area was found in both species. It is suggested that the juveniles preferred the type of sand in which they can bury themselves most easily.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To examine the role of the lateral-line canal in schooling, the canals of the red sea bream Pagrus major (mean body length, 16.7cm) and the bluegill Lepomis macrochirus (7.8cm) were denervated by cutting the main trunk ramus of the posterior lateral line nerve, mandibular, superficial opthalmic and buccal rami of the anterior lateral line nerve without removing the eyes. Schools of 20 individuals were videotaped over 2 hours while cruising in a tank and mean distances to the nearest neighbor (NNDs) were obtained. In both species, the fish with the denervated canals swimmed slowly in a school but the effect of the sensory denervation on schooling was evident; their NNDs were significantly larger than those of the control. It was hypothesized that the canals on the head were different from the trunk canal in their role in schooling.抄録全体を表示PDF形式でダウンロード (293K) -

ジャーナル フリーThe annual life cycle and distribution of adult Lepidotrigla microptera were studied in the Mutsu Bay, Aomori Prefecture. The seasonal changes in gonadosomatic index, hepatosomatic index, condition factor, and stomach contents index of samples obtained by experimental bottom trawls from March 1986 to July 1988 indicated that the annual life cycle of adult L.microptera was divided into the following four periods; wintering period (December-March), preparatory period for spawning (April-May), spawning period (June-August), and preparatory period for wintering (September-November). The habitat of L. microptera in this study area was not confirmed. However, at least a part of them were concentrated in relatively warm waters (6-9°C), i.e. the mouth of the bay in winter. In spring, most of them moved to the western part of the bay (West Bay) with rising bottom water temperature. In summer their habitat spread over the bay, and the fish concentrated toward the mouth of the bay in autumn.
The annual life cycle and the space utilization pattern of adult L. microptera are thus associated greatly with seasonal changes in the bottom temperature.抄録全体を表示PDF形式でダウンロード (503K) -

ジャーナル フリーDevelopmental processes of the internal organs of the swimming crab Portunus trituber-culatus were observed histologically for the zoea, megalopa and juvenile stages. At zoea 1, the following organs were partly organized; the nervous tissue, digestive tract, gnathal appendages, heart and gills, as well as the respective muscular systems. At zoea 2, the brain differentiated the olfactory lobe, the heart was enlarged, and the midgut gland ramified its diverticula. At zoeae 3 and 4, the muscles related to the appendages and ab-domen were developed. In the megalopa stage, the thoracic ganglion developed its pos-terior neuropiles and differentiated the rudiments of the abdominal ganglions. The gill lobes were transformed into a lamellae shape which corresponded to the juvenile type, rather than the bole-shape which lacks branches, as observed in previous stages. At the juvenile stage, the abdomen was reduced, but the structure of the thoracic ganglion was principally the same as that of the megalopa. The midgut gland showed further rami-fication.抄録全体を表示PDF形式でダウンロード (701K) -

ジャーナル フリーThis paper deals with mathematical modeling of fish behavior in a water tank. The time series data are obtained by sampling the video image data recorded in a water tank experi-ment. The model presented in our earlier papers describes the behavior of each individual in a school. Then, it is applicable to the case of small school. In order to construct an aggregation model for large school, our investigation is based on the following assumption: The behavior of fish school can be decomposed into two components. One is the motion of a representative of the school. The other is the variation of the school size.
In this paper, we consider a model for describing variation of the school size. For this purpose, a water tank experiment is made by using twenty bitterling. An autoregressive model is presented for describing this phenomenon. The model order is determined by minimizing the AIC. The unknown parameters are estimated by applying the Burg algorithm. The validity of the model is examined by a residual whiteness test and a simulation study.抄録全体を表示PDF形式でダウンロード (432K) -

ジャーナル フリーThe stocking effects on the population are considered using Lomnicki's model which assumes that the resource use of an individual is a function of its rank. When the indi-viduals are in scramble competition, if the number of natural individuals is small, the stock-ing increases the population size. The heavy stocking destroys the population completely. When the individuals are in contest competition, if the number of natural individuals is small, the stocking increases the population size. If the stocked individuals are superior to natural ones in utilizing natural resources, the heavy stocking depress the natural individuals. and finally, the natural individuals are replaced by stocked ones.抄録全体を表示PDF形式でダウンロード (308K) -

ジャーナル フリーThe spontaneous rosette formation of peripheral leucocytes of carp with red blood cells of various mammals was investigated. Spontaneous rosette formation was observed with SRBCs, HRBCs and BRBCs with the frequency of rosette formation being higher with SRBCs and HRBCs than with BRBCs. Variations in surface morphology, in cell size of the rosette forming cells and in rosette formations were observed under light and scanning electron microscope. However, by examining Giemsa-stained preparates, the RFCs were identified as lymphocytes. The spontaneous rosette formation occurred gradually depend-ing on the incubation time. The spontaneous rosette formation was not specific to SRBCs and was observed at a temperature range of 0°C to 37°C. In these respects the rosette formation of carp lymphocytes differed from the earlier reported rosette formation of mam-malian lymphocytes.抄録全体を表示PDF形式でダウンロード (1249K) -

ジャーナル フリーThe resistance to vibriosis of triploid ayu induced by cold shock and normal diploid ayu were compared by the susceptibility to Vibrio anguillarum and the potency of vibriosis vaccine as parameters. It was demonstrated by immersion challenge experiments that there was no difference in susceptibility to V. anguillarum between the two groups. The artificial challenges with V. anguillarum were also attempted at 1, 2, 3 and 8 weeks after an immersion vaccination. The relative of percentages survival in triploid was slightly lower than that in diploid, but the difference was not sigrificant. From these results, it is suggested that the resistance to vibriosis in triploid ayu is quite similar to that of normal diploid ayu.抄録全体を表示PDF形式でダウンロード (339K) -

ジャーナル フリーThe condition of infestation by the spionid polychaetes which bore into the shells of the scallop Patinopecten yessoensis on the coast of Hokkaido and Tohoku district was studied. The boring polychaetes were identified as Polydora convexa, P. concharum, P. variegata and P. websteri. Large numbers of P. convexa and P. concharum bore into the shells of the cultured and natural scallops in Shibetsu and Notsuke. Polydora variegata were extracted from almost all the sampling stations. Many borings of P. websteri were seen in Hiranai. Heavy infesta-tions by Polydora were observed in the scallops collected in 3 stations, Shibetsu, Notsuke and Kukurizaka. Each Polydora species had morphological characters in its burrow formed by itself. The soft-Xray photographs are very useful in identifying the boring species and also the condition of inner infestation.抄録全体を表示PDF形式でダウンロード (824K) -

ジャーナル フリーSeveral marine biological samples were collected from the Pacific coasts of Ibaraki and Aomori Prefecture in 1987 to 1989, and 239, 240Pu and 137Cs concentrations were measured. A comparison was a lso made between some pelagic and benthic fishes for their radio-nuclide concentration.
239, 240Pu contents of coastal fishes were higher in viscera, and muscle usually showed the lowest value. On the contrary, 137Cs contents were rather higher in muscle.
The diffierens of radionuclide concentrations were found among species, but no de-finite regional variation was observed between the Ibaraki and Aomori coasts.
The 239, 240Pu concentration level in coastal fishes was higher than that in pelagic ones, and no significant difference was observed between pelagic fishes from warm water masses and cold water masses. On the contrary, 137Cs contents of the pelagic fishes showed clear difference between warm water species and cold water ones.
The surface and benthic fishes seemed to show similar concentration levels of radio-nuclides.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A considerable amount of catch was recently obtained by tuna long-line using monofilament nylon on the small and coastal fishing boats.
Actual tests on the research and training vessel were conducted to evaluate the catch rate and operation efficiency using monofilament long-line and the possibility of commercial tuna operation for large fishing vessels
The results showed that the catch rate using monofilament gear reached a mean value of 2.71% and the catch efficiency was approximately 6.7 times as compared with that of ordinary gear. However, this method needed much time for line casting operation and hauling opera-tion. Moreover the tangling rate of the branch line showed a high value. With improvements in the mechanization and handling, this method could be introduced to large fishing vessels as the catch rate had a high value.抄録全体を表示PDF形式でダウンロード (417K) -

ジャーナル フリーSensitivities to alanine, arginine, proline, tryptophan, valine, betaine, uridine 5'-monophosphate and diluted sea water were studied for 83 single fibers of the palatine taste nerve (ramus palatinus facialis) in the young yellowtail Seriola quinqueradiara.
Results of the analysis of the impulse numbers elicited in the first one or first two seconds after the onset of stimulation showed that the sensitivities to the 8 stimulants were not randomly distributed among these fibers: most of the fibers were specifically sensitive to a limited number of stimulants and some were only sensitive to one. Thus, the fibers obtained were classified into five major groups in their sensitivity patterns: (1) fibers responding specifically to tryptophan, uridine 5'-monophosphate and diluted sea water; (2) those responding well to betaine, proline and valine; (3) those responding only to betaine; (4) those responding well to alanine and arginine; and (5) those responding only to alanine.抄録全体を表示PDF形式でダウンロード (549K) -

ジャーナル フリーA new type fish meat for foodstuff prepared by grinding sardine meat in a relatively small quantity of water and separating using high-speed centrifuge was tentatively called the highly nutritional fish meat (HNFM) in this series of studies. In this study, changes in the amount of various nutritive components of HNFM at every step of processing was investigated in comparison with the case of conventional surimi processing.
The lipid content of HNFM was as low as 1/10 of that of minced meat. This indicates that lipid in the sardine muscle was very effectively removed in HNFM processing process. Fish odour was also fairly removed. While large amount of triglyceride was removed, a greater part of phospholipid remained in HNFM along with other miner components. On the other hand, 20-40% of water soluble component including amino acids such as taurine were found to be preserved in HNFM. The taurine content in HNFM was relevantly higher than that in conventional surimi.
Moreover, the relative amount of myofibrillar protein in HNFM was larger than that in conventional surimi due to the effective removal of lipid.抄録全体を表示PDF形式でダウンロード (628K) -

ジャーナル フリーTrypsin-like enzyme in hepatopancreas of shrimp Penaeus indicus was obtained as two fractions (P1 and P2) from shrimp extract by an FPLC system using a Mono Q ion ex-change column. The enzyme in the peak P2 was purified. The enzyme has a single polypeptide chain with a molecular weight of 36, 000, although the enzyme showed a molecular weight of 18, 000 on gel filtration. Isoelectric point was estimated to be below 3.0 by isoelectric focusing. The enzyme showed broad pH optimum (pH 6.5-11.0) and stability (pH 6.0-12.0), and was most active at 45°C. The Km value for the synthetic sub-strate (α-N-benzoyl-1-arginine-p-nitoroanilide) was 294μM. The activity of the enzyme was almost completely inhibited by phenylmethansulfonyl fluoride or trypsin inhibitor (soybean). Propanol was a potent activator for the enzyme, the activity was extremely activated by propanol. The activity was approximately 4 fold at 30°C, and 177 fold at 4°C in the presence of propanol of the concentration of 25%.抄録全体を表示PDF形式でダウンロード (701K) -

ジャーナル フリーThe lipid class compositions of the different tissues and stomach contents from the giant squid Moroteuthis robusta of the northwestern Pacific Ocean were investigated.
In this species, the liver contained a remarkably large amount of lipids, which were characterized by a high percentage of triglycerides and diacyl glyceryl ethers. Conversely, the above types of lipids were not detectable in the flesh and gonad lipids, but were high in phospholipids. In addition, lipids from the stomach contents also consisted of large amounts of diacyl glyceryl ethers. Glyceryl ethers derived from diacyl glyceryl ethers of the liver and stomach contents were very similar in composition. The most abundant component was chimyl alcohol followed by selachyl alcohol. Fatty acids of diacyl glyceryl ether and/or triglycerides in the liver and stomach contents lipids were similar in composition, respectively. Also discussed are the fatty acid compositions of the total lipids obtained from the examined body tissues and stomach contents.抄録全体を表示PDF形式でダウンロード (358K) -

ジャーナル フリーMackerel water-soluble proteins' concentrates (SPC), which had been concentrated by the ultrafiltration system, were treated with three kinds of methods. The gel formation properties were also studied on the insolubilized SPC.
Over 95% of protein in the SPC was insolubilized by two pH shifting methods: One was to adjust the primary pH of SPC lower than 3 then to 7, the other was to adjust the primary pH of SPC higher than 12 then to 7. The preferable gel was obtained by the pH shifting from 12 to 6.
An elastic gel like Kamaboko was obtained from SPC by simple heating when SPC was highly concentrated (over 100mg/1).
The alcohols caused insolubilization of SPC and the rate of the insolubilization increased with increasing of the carbon chain length of added alcohols. Insolubilized SPC with 50% ethanol formed a gel by heating, but its gelation property was poor. Fish water-soluble proteins were presumed not to cause gelation; we found, however, that the fish water-soluble proteins could form a gel if they were concentrated by an appropriate method like ultrafiltration.抄録全体を表示PDF形式でダウンロード (379K) -

ジャーナル フリーSalt concentration of minced meat from walleye pollack was fixed among 0.14-2.1M by soaking in 3M NaC1 for various periods at 4°C. During the dehydration of the cured meat at 30, 40, and 50°C. inactivation of myofibrillar Ca-ATPase and formation of myosin heavy chain polymer (as estimated on SDS-polyacrylamide gel electrophoresis) were investigated.
On dehydration of the uncured meat containing NaCl corresponding to 0.14M, its myofibril-Jar Ca-ATPase activity and myosin heavy chain were hardly changed irrespective to dehydrat-ing temperature. Whereas the cured meat containing 0.9M NaCl was dehydrated at 30°C. myofibrillar Ca-ATPase was slowly inactivated with the accumulation of myosin heavy chain polymer having a relatively larger molecular size (HCn').
On dehydration, with the rise in temperature of over 40°C together with the increase in NaCI concentration of cured meat, myofibrillar Ca-ATPase was rapidly inactivated and the myosin heavy chain polymer (HCn') did not accumulate much.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Effects of pyrophosphate and divalent metal ions (Mg2+, Ca2+) on actomyosin were examined by viscosity measurement and electron microscopy. Various media were added to actomyosin solution, and the mixtures were applied to the above examination.
In the case of protein concentration of about 3mg/ml, the viscosity decreased only in the medium containing 10-4M pyrophosphate and 5mM Mg2+ On the other hand, in the case of protein concentration of 5.2mg/ml, the decrease in viscosity was recognized in all media containing 10-4M pyrophosphate, and it was remarkably accelerated by the addition of Mg2+ (5mM, 25mM). The association of actin and myosin was obviously recognized in a medium by a greater decrease in the viscosity.抄録全体を表示PDF形式でダウンロード (1853K) -

ジャーナル フリーThe experiments were carried out to elucidate the reasons why marked increase in the pH of kusaya gravy after fish immersion occurred only in a beaker and did not in a manufacturer's large tank.
Changes in chemical components such as organic acids, volatile basic nitrogen and polyamines were analysed during storage of kusaya gravy in vitro. Acetic acid showed the most significant decrease by about 0.8% in the gravy of which pH increased from 7.0 to 8.8 after 8 days' storage at 20°C. When acetic acid was added into this gravy to give the concentration of 1%, the high pH recovered to below 7. Spiral bacteria isolated from kusaya gravy consumed acetic acid.
Drastic increase of pH value, accompaninig the growth of spiral bacteria, was observed in the gravy kept in an open beaker and was not observed in a screw-capped bottle. A great increase in the pH value was not observed in the bottom layer of the gravy infused in a long tube during 3 months' storage.
These results suggest that a reason why the pH of the gravy kept in a large tank in situ did not greatly increase is that spiral bacteria can hardly grow to consume organic acids like acetic acid in the inner part of the gravy.抄録全体を表示PDF形式でダウンロード (534K) -

ジャーナル フリーA food stuff tentatively named highly nutritional fish meat for food stuff (HNFM) was prepared from round sardine stored for 5 days at 2°C by the method previously described, and the changes in several properties were investigated. The quantity of volatile com-pounds (VC) arisen from the minced meat increased during the storage of the round sardine, but that from HNFM hardly changed. HNFM prepared from the stored sardine gave off little undesirable odor.
The gel-forming ability and myofibrillar Ca-ATPase activity of HNFM rapidly decreased during the storage of the round fish even at a low temperature as raw material. On the contrary, Ca-ATPase activity of dewatered-ground meat was kept at a high level during the storage, and the deterioration of gel forming ability was remarkably suppressed.
For the purpose of manufacturing the HNFM of high quality, it is essentially important to prepare it from the fresh fish as rapidly as possible and to freeze it with the addition of cryoprotectants.抄録全体を表示PDF形式でダウンロード (444K) -

ジャーナル フリーCultured yellowtails were killed by the following three different methods; (1) stabbing the spinal bulb, (2) dipping in cold sea water and (3) letting them to die in the air.
Immediately after death, the fish were stored at 5°C. Rigor index, ATP and its relative compounds, and hardness of the fish meat were measured at constant time interval to examine the relationship between the rigor phenomenon in the round fish and the hardness of the fish meat. The full rigor mortis was observed after 10h, 6h and 2h for the fish killed by the (1), (2) and (3), methods respectively.
No correlation was observed between the external hardness of the round fish and the hardness of the dorsal meat. The hardness of meat showed the highest value just after death and did not increase during storage.
As the stabbed fish maintained the hardness of meat longest after death, this method was found to be the most effective to offer high textural quality sashimi.抄録全体を表示PDF形式でダウンロード (422K) -

ジャーナル フリーNine inorganic elements, i.e., calcium (Ca), phosphorus (P), iron (Fe), sodium (Na), potassium (K), magnesium (Mg), zinc (Zn), manganese (Mn) and copper (Cu), were determined in edible aquatic animals: fourteen species of fish, two species of shrimp and three species of shellfish, in Lake Biwa in Japan.
The results obtained were as follows.
(1) The contents of Ca and P were generally high in whole body or semidressed part of fishes and whole body of shrimps. High levels of these elements were considered to be due to the presence of bone, scale or shell.
(2) The contents of Fe and Cu were generally high in liver or hepatopancreas of fishes and the content of Fe was especially high in the stripped part of Setashijimi and Cu was especially high in liver of Biwamasu.
(3) The content of Na was relatively high in liver or hepatopancreas of fishes and whole body of shrimps.
(4) The content of K was relatively high in muscle of fishes and was low in stripped part of shellfishes.
(5) The content of Mg was relatively low in stripped part of shellfishes.
(6) The content of Zn was high in ovary of fishes.
(7) The content of Mn was especially high in stripped part of Karasugai and Ishigai.抄録全体を表示PDF形式でダウンロード (470K) -

ジャーナル フリーThe softening process of fish bone was studied to utilize fish bone as a calcium source in human diet. To reduce the loss of soluble components of fish tissue during cooking, heating by super-heated steam was examined. Since drying of fish tissue might occur during super-heated steam cooking, the softening rate of mackerel spine and the moisture loss of mackerel meat cooked in super-hated steam were determined for samples cooked at 120°C and 130°C under pressures in the range from 1.2kgf•cm-2 to 2.7kgf•cm-2 (absolute pressure). The softening reaction conformed to an apparent first-order reaction. The softening rate constant apparently depended on the pressure of the super heated steam and not on the temperature of the steam. It is interpreted from the results that the temperature of the spine was the saturation temperature of the super-heated steam which depends only on the total pressure and is independent of the temperature of the super-heated steam. The softening rate constant was represented by an Arrhenius type equation, as following: log (k)=12.2-5.96×103 (1/T ?? ), k: the softening rate constant (s-1), T ?? : the saturation temperature of the super-heated steam. The loss of moisture during cooking was small (2.5%-7.9%).抄録全体を表示PDF形式でダウンロード (344K) -
