ジャーナル フリーThe avoidance response of the jack mackerel Trachurus japonicus to a strobe light barrier was investigated in the laboratory, by electrocardiogram measurement.
The avoidance response varied with the strobe flash frequency (1.7-430 Hz) and strobe light intensity. Avoidance was greatest at flash frequencies of 5 and 10 Hz and clearly decreased as the strobe light intensity (15 Ix•s) was reduced.
Heart rate increased when the fish stayed in the dark section of the tank or approached the barrier, but decreased when fish avoided or passed through the barrier or strobe light. Therefore, heart rate change can be used as an index of fish response to the effect of strobe light stimuli.抄録全体を表示PDF形式でダウンロード (413K) -

ジャーナル フリーSampling surveys to investigate the diet composition of Hippoglossoides dubius and distribution of megalobenthos were conducted from June 1985 to September 1986 in Funka Bay and its offshore waters. In the bay, Ophiura spp. was the predominant species, followed by Crangon dalli, Tachyrhyncus reticulatus, Haustator fortilirata, and Turritellopsis acicula stimpsoni. In the northeastern part of the bay mouth and outside the bay, the species composition fluctuated with season. The principal food of H. dubius was the dominant species in megalobenthos communities through the year except for mollusca with hard shells. It is inferred that the seasonal and geographical differences in the diet of H. dubius reflect the megalobenthos communities.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 effects of light quality and quantity on growth of germlings and thalli of Sargassum horneri and S. patens were examined in an indoor culture. Red, green, blue and white light were used at 3-5 different levels from 10 to 120 μE/m2/s. The effect of light quality on their growth was the same in the germlings and thalli of both species. Growth of S. horneri was the best under white and blue light, better under green, but very poor under red light. Though S. patens did not grow under red light, it grew vigorously at similar rates under the other three light sources. As for the light quantity, both species grew well with more light. S. horneri grew 2-4 times faster than S. patens.抄録全体を表示PDF形式でダウンロード (669K) -

ジャーナル フリーThe small otter trawl fisheries in Osaka Bay use cod-end of small mesh size of about 20mm in stretch measure, since their target species are white-spotted conger Conger myriaster and small shrimps e. g. the southern rough Shrimp Trachypenaeus curvirostris. Many juveniles, which play an important role for future resource control, are caught and discarded at sea immediately after net hauling because most of these juveniles are smaller than the commercial size.
This paper describes the mesh selectivity for white-spotted conger. Fishing experiments were carried out using an existing trawl with cover net in July and October 1991. The trawl used had a cod-end of four mesh sizes (21.2, 22.5, 25.0, and 27.0mm) and the mesh size of the cover net was 15.3mm.
Mesh selectivity for white-spotted conger is shown as a function of G/P (body girth/mesh perimeter). Mesh selectivity increases at G/P=1, reaching 100% at a G/P of about 1.25. This indicates that white-spotted conger can pass through a mesh of slightly smaller perimeter than their own body girth.抄録全体を表示PDF形式でダウンロード (391K) -

ジャーナル フリーCapture probability for the anchory larva Engrauris japonicus was estimated from the day-to-night ratio of catches with 23.4cm BONGO net (B-net) and 130cm ring net (R-net) respectively. The two samplers were towed obliquely from a depth of about 45m at 7 stations during the day and night. During the day, the B-net caught more larvae than the R-net over 5mm S. L. At night, the B-net caught almost the same number of larvae as the R-net winthin the range of 4-7mm S. L. and caught more larvae than the R-net over 7mm S. L. The day-to-night catch ratio (CD/CN) of each sampler decreased rapidly with increase of length of larvae. At 10mm S. L., CD/CN of the B-net was about 0.2 and that of the R-net was about 0.05. These results indicate that the capture probability of the B-net is higher than that of the R-net and that larvae over 7mm S. L. can avoid the net at night. At 10mm S. L., capture probaility during the day was estimated to be less than 0.2 with the B-net and less than 0.05 with the R-net.抄録全体を表示PDF形式でダウンロード (531K) -

ジャーナル フリーGrowth of bacteria isolated from a new blade surface of the brown alga E. bicyclis was stimulated by algal excreted organic matter (EOM). The bacteria utilized some major algal components such as mannitol, fucoidan and alginate, but failed to utilize laminaran. Two fractions of EOM were obtained by elution on an activated charcoal column. The effect of these two fractions on growth was different. The first fraction caused bacterial cell density to increase linearly with concentration, whereas the second fraction stimulated bacterial growth at low concentration, yet increasing concentrations did not cause an increase in cell density. From the result of 1H-NMR, the second fraction seemed to consist of some sugars and phenolic substances.抄録全体を表示PDF形式でダウンロード (413K) -

ジャーナル フリーThe specific gravity of black sea bream Acanthopagrus schlegeli larvae and juveniles was measured in a series of saline solutions. The volume of the swim bladder and wet and dry fish weights were also measured. During the egg and prelarval periods, they have a slightly positive or neutral buoyancy in sea water of ca. 1.024 specific gravity. During the postlarval period, specific gravity increased to a level ca. 1.028 and began to change diurnally. After inflation of the swim bladder, voluminal changes in it caused the postlarvae to be negatively buoyant during the day and neutlally buoyant at night. These changes could be induced by manipulation of the photocycle. No diel change in specific gravity could be detected in black sea bream of 20mm. These results indicate that levels in the specific gravity of black sea bream during the larval and juvenile periods are much lower than those reported for the red sea bream during this same period. It has been suggested that this difference influences the differences in behavior of these two sparids which results in differences in the vertical distribution from the pelagic to benthic life.抄録全体を表示PDF形式でダウンロード (1165K) -

ジャーナル フリーIn order to determine the mechanism of histamine (Hm) formation in scombroid fish stored at low temperature, total viable and luminous bacterial counts (TVC and LBC), bacterial flora, Hm contents in several parts of mackerel stored in ice and at the temperature of ice, and Hm formation by the isolates were studied.
In the first experiment (Exp. I), Hm was formed in the muscles during storage at the temperature of ice but not in ice. Hm content was far higher in the ventral muscles than in the dorsal muscles. P. phosphoreum grew in the abdominal walls in both storages (ca. 81% in LBC/TVC), and in the muscles during storage at the temperature of ice (ca. 2.5% in LBC/TVC). P. phosphoreum isolated formed a high level of Hm. In the second experiment (Exp. II), a small amount of Hm was formed in the muscles, especially the ventral muscles, and P. phosphoreum was not found in fish before and after storage. These results indicate that P. phosphoreum plays an exclusive role in histamine formation in mackerel stored at the temperature of ice.
Both whole and halophilic bacterial floras were dominated by Vibrio in all the parts (skin, muscle, abdominal walls) of fish in Exp. I and by Pseudomonas or Moraxella in Exp. II. Photobacterium leiognathi was found in all the parts of fish before storage in Exp. I but not in Exp. II, and P. phosphoreum also grew only in fish after storage in Exp. I as above. Pseudomonas or Moraxella dominated also in Exp. I after growth of P. phosphoreum. These results suggest that Photobacterium grows in the flora dominated by Vibrio, especially halophilic floras, and hardly grows in the flora dominated by Pseudomonas or Moraxella.抄録全体を表示PDF形式でダウンロード (739K) -

ジャーナル フリーThe present work was carried out to investigate factors influencing histamine formation by washed cell suspensions or cell-free extracts and growth in each condition on Photobacterium phosphoreum isolated from mackerel when stored at 0°C.
In the study of the effects of the reaction temperature on histamine formation and histamine forming activity, the optimum was at 35-40°C, and this was also observed at 50°C. Also while the growth was optimum at 25°C growth did not occur at 35°C. In regard to the effect of the reaction pH value, the activity was optimum at pH 5.5-6.5 and did not occur at pH 8.0, while growth was good at pH 5.5-8.0. In regard to the reaction NaCI concentration, the activity of the washed cell suspensions was optimum in 2-4% and low in 1 and 5%, and the activity of the cell-free extracts was optimum in the absence of NaCI and decreased with an increase of the concentration, while the growth was similar to the trend obtained on the activity of the washed cell suspensions. In regard to the reaction histidine concentration, activity increased quantitatively in the concentration above l00μg/ml and did not vary in that under 10μg/m/. In regard to the culture age, the activity was low in the early logarithmic phase, became maximal in the latest logarithmic phase, and decreased with the age of the culture. In regard to the presence of glucose in the growth medium, the activity increased in the presence of glucose and the activities with incubation time were different between the presence and the absence of glucose, while the pH value of the culture decreased with an increase of the activity. In regard to the oxygen tension of the culture medium, the activities were higher in anaerobic culture than in aerobic one, while growth was higher in the aerobic one.抄録全体を表示PDF形式でダウンロード (451K) -

ジャーナル フリーKamaboko gels were prepared by adding 0.5% food additive, bovine plasma powder, by preheating at different temperatures from salt-ground meat of walleye pollack frozen surimi. The quality of kamaboko gel thus formed was compared to kamaboko formed without additive. The gelling property of the salt-ground meat with bovine plasma powder varied with the temperature of preheating. At 30°C and less, the breaking strength and breaking strain of the kamaboko gel formed with the additive was much higher, whereas the breaking strength and breaking strain of the kamaboko gel formed at 40°C and above remained low. However, the quality of the kamaboko gels formed with the bovine plasma powder was generally found to be similar to that of the products on the market by a sensory test, although gel strength and spring constant of products were slightly different.抄録全体を表示PDF形式でダウンロード (517K) -
