This device measures fish fat percentage based on the condition of its cells. These
cells change from the day of the catch as the fish erodes. In order to measure the
fish fat accurately, this device uses 2 measuring modes. One mode is to measure on
the day of catch (within 24 hours) and the other mode is to measure in 72 hours after
catch (day after the catch). The “day of the catch” refers to the day when the fish is
caught and has died.
It also depends on the fish species. As for Saury, Bonito, Sea bream, Sailfin sandfish, Sea ell and Horse
mackerel, use day of the catch mode since there is no mode for measuring the next day. For measuring
correctly in both modes, fish should be kept in an ice storage.
● Taking measurements in the fish processing lines.
If you’re taking measurements in fish processing or in the warehouse, the fish may still be alive. If you take
measurements immediately after when the fish died, you may get a lower fat percentage. We recommend that
you first store the fish in ice and wait at least one hour before making measurements. Also, if several days have
passed since the death, please take the measurement using the “next day after catching” mode.
In Fish Analyzer
TM
PRO, the “status of the fish” or fish freshness is displayed in 5 levels next to the fat
percentage. When several days have passed since its death, if the device shows "A '" or "A", choose the “day of
catching” mode. If it shows "B" or "C", choose the “next day of catching” mode.
● The “next day of catching” means measurement at the distribution site.
When using the Fish Analyzer
TM
to measure fish freshness, take the measurements as soon you receive the fish.
The Fish Analyzer
TM
PRO displays the “status of fish” (fish freshness) along with the fish fat percentage in 5
levels. If the fish freshness level results in "D" grade, this refers to being difficult to obtain an accurate fat
percentage and should not be used.
