CarpChip carp tagging kits use PIT microchips to give individual fish a permanent electronic ID, helping fisheries track growth, welfare records and stock history over time.
Designed for commercial fisheries and independent carp lakes, CarpChip makes fish identification simple.

Microchipping your fish should always be carried out responsibly. Correct fish handling, suitable equipment, appropriate tag selection and good implantation technique are important.
CarpChip provides guidance to help commercial fisheries understand the correct approach to carp tagging, scanning and logging of data. The aim is simple: reliable long-term identification while protecting fish welfare.

Good fish management relies on understanding what happens to an individual fish over time.
Once a carp has its own ID, future observations can be connected to the correct fish.
That can include:
- Weight changes
- Welfare observations
- Capture frequency
- Growth trends
Rather than keeping isolated notes, the fishery gradually builds a long-term welfare history for each tagged

Knowing what a carp weighs today is useful.
Knowing that the same carp weighed 34lb two seasons ago, 38lb last year and 42lb today tells you considerably more.
Because the microchip identifies the individual fish, each new weight can be connected to its previous records.
Over time you can begin to see:
- Which carp are growing fastest
- Which strain is performing best
- How recently stocked fish are developing
- How your overall stock is progressing
For commercial fisheries investing heavily in their fish stock, that information can become extremely valuable.
A kit to microchip your carp gives a fishery the equipment needed to permanently identify individual carp.
CarpChip uses small passive PIT tags containing a microchip. Each tag carries its own unique electronic identification number.
Once a fish has been appropriately microchipped, a compatible handheld scanner can read that number whenever the carp is caught again.
That unique ID can then be linked to information such as:
- Fish name or reference
- Species & Stocking Information
- Photographs
- Capture dates, Growth history and Weight
- Welfare observations
- Lake records
This gives the fishery a reliable way to identify individual carp rather than relying only on photographs, markings or memory.


In practical terms, the terms are often used to describe the same process. Tags often sit outside the body, at CarpChip we recommend small microchips that are placed under the skin on the fish. This is safe and easy to do, with extensive research backing the process.
With CarpChip, a carp is tagged using a PIT microchip.
The most useful way to think about it is:
Microchipping a carp describes what you are doing.
PIT tagging describes the identification technology.
Microchipping is the familiar way of describing the small electronic chip used to identify the fish.
All three terms refer to the same goal:
Giving an individual carp a reliable electronic identity.
A PIT microchip — Passive Integrated Transponder — is a small electronic identification device used to give a fish a unique ID.
Microchipping fish with PIT tags is widely used in fisheries and fish research where individual fish need to be identified over time.
The microchip does not need its own battery.
When a compatible scanner is passed near the tag, the scanner reads the unique identification number stored within it

That can be an important reason for tagging.
But permanent identification can provide much more value to a commercial fishery.
Once a fish has a unique ID, every future capture creates an opportunity to add more information to its record.
Over several seasons, you can build a much clearer picture of:
- Growth
- Condition
- Capture frequency
- Stock history
- Fish welfare
- Important individual carp
Identification becomes data.
Data becomes history.
History helps you manage your lake.
Designed for Independent and Commercial Carp Fisheries
You do not need to operate a large aquaculture facility to benefit from microchipping your fish.
CarpChip is designed around the practical needs of commercial carp fisheries and independent lake operators.

Many fisheries still keep stock information across a mixture of:
- Paper notebooks
- Spreadsheets
- Photographs
- Social media posts
- Angler reports
- Staff knowledge
- Memory
The problem is that information becomes fragmented.
A permanent fish ID gives you one consistent reference around which the fish's information can be organised.
For fisheries wanting to take this further, CarpChip Lake Tracker connects individual fish IDs with their records, catches, photographs and weight history.
Instead of searching through paperwork, you can build a living digital history for each carp.
Please reach us at hi@carpchip.com if you cannot find an answer to your question.
Know Exactly Which Fish You Have
Two carp can look remarkably similar.
Photographs and scale patterns can help, but identifying fish this way can become difficult as your stock grows.
A PIT tag gives each carp its own machine-readable identity.
Scan the fish and you can confirm exactly which individual carp you are handling.
A CarpChip tagging setup can include:
PIT Microchips: (We can advise on the suitable size for your lake). These are small passive electronic tags carrying an individual identification number.
Handheld Fish Scanner: A compatible scanner used to detect the tag and display the fish's unique ID.
Tagging Equipment
Equipment required to administer the PIT tag appropriately.
Fish Identification Records
A simple method for connecting each microchip number to the correct fish.
CarpChip Lake Tracker
An optional digital lake management system for fisheries wanting to link fish IDs with growth, capture and welfare records.
The process is straightforward.
1. Tag (microchip)the Carp
A suitable PIT microchip is implanted using appropriate fish handling and tagging procedures.
2. Scan the Chip
The unique electronic ID is read using a compatible handheld scanner.
3. Record the Fish
Connect the tag number to the fish's information, photographs and current weight.
4. Scan Future Captures
Whenever the fish is caught again, scan it to confirm its identity.
5. Build Its History
Add the latest weight, capture information and welfare observations to the same fish record.
Over time, each tagged carp develops its own reliable history.
What is the best way to identify individual carp?
A PIT tag provides an individual carp with a unique electronic identification number that can be read with a compatible scanner.
This allows the fishery to positively identify the same fish during future captures.
Carp can be identified using PIT microchips designed for animal identification.
Each tag contains a unique number that can be detected using a compatible scanner.
Appropriate fish handling, tag selection and implantation technique are important.
A PIT tag is a small passive electronic identification tag.
It carries a unique identification number and does not need its own battery.
When a compatible scanner is placed near the tag, the number is displayed.
A PIT tag contains a microchip and is commonly described as a microchip.
In fisheries and research, PIT tag or PIT tagging is the more technical terminology, while microchipping is often easier for the general public to understand.
Fisheries can tag carp to support:
- Individual fish identification
- Growth monitoring
- Fish welfare records
- Stock management
- Capture histories
- Stock verification
- Theft deterrence and identification
The unique ID provides a permanent reference around which the fish's history can be built.
No.
The PIT tag stores the fish's unique identification number.
The fishery records the weight separately and connects it to that ID.
This means future weights can be compared against the same individual fish.
Yes.
Because individual carp can be reliably identified, observations about weight, condition, injuries and other welfare information can be recorded against the correct fish.
That makes long-term welfare records more useful.
Yes.
Fish tagging can help fisheries maintain more accurate stock records, monitor growth, track capture histories and maintain individual fish welfare information.
Permanent identification gives operators better information for managing their stock.
No.
CarpChip PIT tags and scanners can be used independently.
The CarpChip Lake Tracker is available for fisheries that want to connect those IDs with digital fish profiles, captures, photographs, growth records and welfare information.
