Message from supervisors
Traditionally, the quality of marine products at the distribution stage has been subjectively evaluated by the
experience of distribution specialists and has not been quantified on a certain basis. In order to digitize, it
requires specialized knowledge and special equipment, and we have to rely on time-consuming chemical
methods. Therefore, with the aim of developing a compact device that can measure the content of fat, which is
one of the deliciousness indexes as quality information of marine products, simply and nondestructively,
Nagasaki University Fisheries Department, Nagasaki Prefectural Fisheries Research Institute, Chiba Prefectural
Fisheries Research Center, Yamato Scale Co., Ltd., Fisheries Research Institute (currently National Research
Development Corporation Fisheries Research and Education Organization) jointly developed the technology
conference on agriculture and forestry and fisheries technology 2010 “New Practical Technology Development
Project to Promote Agriculture, Forestry and Fisheries Policy” and "Development of quality measurement
equipment aiming at improvement of fish prices and provision of high quality marine products and fish
processing products", we developed Fish Analyzer TM Pro and have been sold. Fish AnalyzerTM Pro can measure
the fat content of horse mackerel, yellowtail, tuna, sea bream, bonito, and sardines nondestructively and quickly
at fishery sites.
In addition, it is also possible to distinguish fresh fish from frozen / thawed fish. Quality information that can be
measured with this device is branding of tasty superior aquatic products, grasping of raw material characteristics
at the time of manufacturing processed products, quality control of farmed fish, etc. We hope that it contributes
to the sustainable supply of high quality products to consumers.

1-3. Available functions
1 Nondestructive measurement method that does not damage fish.
This device uses the "bioelectrical impedance method" to send a weak electricity
into the fish using four electrodes and estimate the fat percentage from the
impedance. Therefore, the fat rate is displayed in only 4 seconds without
damaging the fish.
2 The multi-frequency measurement method is adopted.
When electricity flows in the low frequency band, electricity flows mainly outside
the cell, and when it flows in the high frequency band, electricity also flows in the
cell. This device has adopted a multi-frequency measurement method in which
electricity flows at multiple frequencies for achieving high accuracy.
3 Measuring the fat percentage of 20 species of fish. (P.11)
This device can measure horse mackerel 1, mackerel 1, Mackerel 2, sardine,
saury, Bluefin tuna (back, belly, tail), Sea bream, Alfonsino, Bonito 1, Salmon,
Rainbow trout, Spanish mackerel, Butterfish, Sea bass, Sailfin sandfish, Grouper,
Bonito 2, Sea eel, Horse mackerel 2.
4 You can also estimate the fat ratio of unregistered fish. (P.20)
It is equipped with "calibration curve mode" to measure unregistered fish. In
impedance mode, the impedance value at 100 kHz is displayed instead of the fat
percentage. From this number, you can know the approximate fat ratio, and you
can also use Fish A, Fish B, and Fish C to create the original formula.
5 Detecting defrosted products
After freezing and thawing the fish, the cell membrane will be destroyed, so the
difference in the flow of electricity will not be seen. Using this feature, fish with
frozen history will be displayed as "defrosted". However, please note that the fat
percentage of the thawed product is not displayed.
6 Displaying the average value of the measurement results. (P. 19)
In order to determine the fat percentage from multiple measurement results, and
also to weigh several fish in a container, and to present it as the average value of
the container, the "average value calculation function" is equipped. The average
value is displayed at the bottom of the screen until you press or turn off the
power.
7 Displaying the fish status (freshness index) in 5 levels (P. 16)
Fish Analyzer TM PRO allows you to determine the condition of fish at the same
time as the fat percentage. The status of the fish is a function to see changes in
in-cells and out-cells, and changes to A ', A, B, C, D according to the deterioration
of cells and the decrease in water holding capacity. It can be used for cooking
guidelines and quality control.
8 Strict quality control can be performed. (P.20)
Fish AnalyzerTM PRO is equipped with "Fish status mode". In the fish status
mode, impedance at 5kHz is displayed along with the 5-step judgment. As the
impedance decreases along with the decrease in freshness, stricter quality control
can be performed by following this process.

2-4. Selection of the day of catching or the next day of catching
This device measures the percentage of fat from the information inside and
outside the cells, but as the cell condition is different on the day and the next day
of catching (the day of lethality), it has two modes for accurate measuring.
Therefore, make sure that you should choose a mode (the day or the next day)
as well as a fish species.
As for Saury, Bonito, Sea bream, Sailfin sandfish, Sea ell, Horse mackerel, there is no mode for
measuring on the next day, so measurement should be performed on the day of catching. For measuring
correctly in both modes, fish should be kept in an ice storage.
●The day of catching means measurement at the production area.
In the case of production areas, fish may still be alive. If you take measurements immediately after
lethality, you may get a lower fat percentage. First, store it in an ice storage and wait at least one hour
before making measurements. Also, if several days have passed since the death in the production area,
please make measurements on the next day after catching.
In Fish AnalyzerTM PRO, the status of the fish is displayed in 5 levels next to the fat percentage. when
several days have passed since the lethality, if the device shows "A '" or "A", choose the day of catching
and if it shows "B" or "C", choose the next day of catching.
●The next day of catching means measurement at the distribution site.
Fish AnalyzerTM is affected by changes in freshness, so make measurements as soon as possible after
procurement. In addition, Fish AnalyzerTM PRO displays the status of fish along with the fat percentage in 5
levels. If the status of the fish is displayed as "D", please think that it is difficult to obtain an accurate fat
percentage.

past measurement results is completed. Press key to return to the normal
screen.
Remarks: Please note that clearing results will erase all past measurement results and the number of measurements.
3-4. Status of fish
There is a K value as the freshness index of fish based on the result of biochemical analysis, but the "Status of fish"
displayed on Fish AnalyzerTM PRO is a freshness index based on "the electrical feature of cells", which is different from the
K value.
This device uses a multi-frequency measurement method and basically the cell membrane has high electrical capacity and
insulation at low frequency bands. As electricity flows outside the cell without flowing inside the cell, the impedance (electrical

Chapter 4 User parameters
17
resistance) is high. Conversely, at the high frequency band, the cell membrane is electrically shorted, and electricity flows
inside the cell, resulting in low impedance.
This is the electrical feature of the cell, while the status of the fish after death changes with time, and the electrical feature
of the cell also changes in the way that reflects it. After death, the impedance rises first in proportion to the tightness of the
fish. This tightness level is "A" or "A '". After that, the fish starts to soften and the impedance starts to decrease but the cell's
electrical characteristics are still maintained. This status is "B". If the fish being measured immediately after death, the device
may display “B” as the condition is similar to the one before the fish starts to tighten, and if blood remains, it may display "C".
When freshness starts to fall rapidly, the impedance at the lower frequency band in particular drops significantly. This is
because the cell's structure changes and the cell's electrical characteristics deteriorates. Moreover, the water holding
capacity of cells decreases, and the intracellular fluid flows out of cells, which lowers the impedance at the lower frequency
band. Since the ability to retain water in cells is undoubtedly an important factor in fish freshness, the electrical feature of the
cells changes, and the status of poor water holding capacity is “C” or “D”. Of course, the status of fish is not irrelevant to the
K value, and the condition of the fish corresponding to the K value of 1% to 20% is "A", "A '" or "B", and the K value is 20% or
more is equivalent to "C" or "D".
Note that “E” is displayed when a measurement error occurs, and “F” is displayed in the case of a thawed product in the
impedance mode and the fish status mode in which “thawed product” is not displayed.
Remarks: It is not possible to decide whether the fish can be eaten raw only by the freshness evaluation as well as the K value.
Basically, fish such as salmon and mackerel, which are not eaten raw, should be cooked before eating even if the status
of fish is good
