Mr Koizumi Professional Koi Measuring Sleeve 65cm

Mr Koizumi Professional Koi Measuring Sleeve 65cm

The Mr Koizumi 65 cm professional koi measuring sleeve combines controlled transfer and measurement in one wet handling tool. It is intended to support a koi along its body while the fish is moved from a pan net to a bowl, treatment vat or measuring station.

Unlike lifting in an open pan net, a proper sleeve supports the fish and retains water around it during a short transfer. The printed or integrated scale provides a useful length check without forcing the koi against a dry ruler.

Handling benefits

• 65 cm measuring length
• Supports the koi during short transfers
• Useful between pond, bowl and treatment vat
• Reduces the need to lift a large koi in a pan net
• Professional Mr Koizumi handling format

Verified product information

Using a measuring sleeve

Prepare the receiving bowl first and fill it with pond water. Guide the koi calmly with a pan net, bring the sleeve under the fish and keep the body level and supported. Avoid sharp folds, prolonged air exposure or carrying the fish farther than necessary.

After use, rinse away mucus and debris, disinfect between ponds and allow the sleeve to dry fully. Biosecurity is particularly important for equipment used at shows, dealer systems or several customer ponds.

Our practical view: Measure and transfer as one calm movement. Repeatedly netting the same koi because the bowl, camera or treatment is not ready causes far more stress than the few seconds saved by rushing the setup.

Frequently asked questions

Can it replace a pan net?

No. Use a pan net to guide the fish into position, then use the sleeve for supported transfer.

Can I carry a koi dry in it?

No. Keep the fish wet and supported and minimise time out of the pond.

Which length should I choose?

Use a sleeve comfortably longer than the largest koi you expect to handle.

Can it be shared between ponds?

Only with thorough cleaning and disinfection to prevent cross-contamination.

Is the measurement suitable for official shows?

Use the measuring method required by the event; this sleeve is a practical husbandry tool rather than a certification device.
