How does the Fish Fat Meter work?

The fish fat (lipid) content measurement is based on the fish water content that is measured by the micro-strip sensor. From the fish water content, the device uses its proprietary calibration algorithm to provide the fish fat (lipid) percentage results.

The Fish Fat Meter was developed and refined the algorithm based on years of research through experience & customer feedback. Its been tested, proven and trusted by world’s most demanding customers for many years.

How accurate is the Fish Fat Meter?

The accuracy of the Fish Fat Meter depends on the overall fat (lipid) content percentage of the fish, please refer to the accuracy guide.

How to read the accuracy guide: when using the Fish Fat Meter and you get a fish fat percentage from 2% to 15%, the accuracy is about ± 0.5% to ± 1.0%.

If the fish fat (lipid) content percent is from 16% to 30%, the accuracy is about ± 1.0% to ± 2.0% and so on. As the total fish total fat (lipid) content increases, so does the percentage of variance in accuracy.

Accuracy Guide:

Fish Fat (lipid) content percentage resultsAccuracy
2% to 15%± 0.5% to ± 1.0%
16% to 30%± 0.5% to ± 1.0%
31% and above± 0.5% to ± 1.0%

What types of fish can the Fish Fat Meter measure?

32 fish types with 73 settings!

The Fish Fat Meter can measure 32 fish types (species) of fish with 73 possible setting.

For every purchase or rental, you get to choose up to 4 species to be pre-calibrated to the device and a “Research” setting to make your own calibration if needed.

Fish Fat (lipid) content percentage results in Seconds & Non-destructive

Depending on the size of the fish, take 1 to 4 measurements per fish for reliable & accurate reading. You’ll get an “average” of those readings as the fish fat (lipid) percentage.

The Fish Fat Meter was designed to be used on live fish so it does no harm to the fish. You can use the fish or sell it with confidence to your customers.

Fish Fat Meter FAQ

Please call us at: 1.800.295.6134 or email at:
We do not provide pricing information on our websites.

In order to use the Fish Fat Meter, the fish has to have a minimum body length (not including head or tail) and thickness to accurately measure the fish fat percentage.

For fish body length (NOT including the head and the tail), it must be at least 1.5 inches (40 mm) long.

For fish thickness, it depends on the overall fish fat content (percentage):
– if the fish fat content is round 1 – 7%, then the fish thickness must be at least 0.28 – 0.31 in (7 – 8 mm).
– if the fish fat content is around 8 – 15%, then the fish thickness must be 0.6 – 0.67 in (15 – 17 mm).
– if the fish fat content is around 16 – 25%, then the fish thickness must be 0.79 – 1.0 in (20 – 25 mm).

These are the absolute minimum body length size and thickness required. If the fish does not meet the requirements, unfortunately, you will not get an accurate result.

The Fish Meter has an accuracy of about +/- 0.5% to 4% accuracy depending on the type of fish and total fat content. Please see the Accuracy Guide above.

The Fish Fat Meter is used to measure fat content (lipid) percentage in fish. It is used in many situations such as fish research with NOAA, USGS and many other worldwide Government and non-Government fish research projects. Used in fish aquaculture farming to measure proper fish diet. Used in restaurants and grocery stores to ensure fish quality standards from suppliers and vendors they work with.

Yes it can. The Fish Fat Meter is a non-destructive and non-invasive measuring device so it does no damage to the fish. You can measure the fish many times as needed without affecting the quality of the fish. After measurement, you can sell it or cook to eat safely.

The Fish Fat Meter can be used to measure on live fish as long as you can hold the fish steady enough to make sure the sensors are in full contact for few seconds with the fish. The Fish Fat Meter is a non-invasive and non-destructive device, so it’s harmless to use on live fish.

It’s a great way to monitor the fish health and growth as it responds to certain diets and environmental conditions.

Unfortunately the Fish Fat Meter can not measure fish fat (lipid) content of frozen fish. The fish must be thawed and unfrozen.

Yes the Fish Fat Meter can measure directly on and through the skin of the fish. It can of course measure directly on the flesh of the fish (e.g. bone side) as well. There are different calibration settings available for each method.

If you measure directly on the lateral line of the fish, the measurements will have more variance when compared with results from measuring above the lateral line.

The reason is that if you measure directly under the skin on the lateral line, there is a strip of flesh which tends to contain more fat. The amount of fat present in this area varies significantly due to seasonal changes.

If you measure above the lateral line, then you are measuring directly into the fish flesh & muscle area. This is much more repeatable (stable) and representative of the fat distribution in the flesh & muscle. We recommend this approach since it’ll give more consistent results with low variance (changes less) over time as seasons change.

Like any scientific and industrial measuring devices, basic regular maintenance and up keep is highly recommended. We want to make sure it’s working properly.

For basic every day use suggestion, please make sure to wipe and clean the sensors after each use. Simple wipe with damp towel or wet wipe will do.

We highly recommend at least a once a year re-calibration and maintenance by the manufacture. This is done for additional fee to ensure the Fish Fat Meter measurements are accurate, precise and working as expected. During the annual maintenance, we will clean, inspect and update the firmware if available. The entire process take about 3 days from the time the Fish Fat Meter is received.

Please call 1.800.295.6134 or email us at: to get started.

The Fish Fat Meter can hold and save up to 1,000 measured data results on the device. After the 1,000 measurements, the measured data results can be downloaded to your PC with the free download cable provided in the kit.

Once the measured data is downloaded to your PC, you can use the free Data Management Software to manage the measured results.

If the fish you want to measure is not on Fish Fat Meter calibration list, you can provide us with the fish species you want to measure and we can recommend a fish that is close to what you want to measure that will give a “good enough” result. You can also create your own custom calibration. Please see the Custom Calibration instructions guide.
