UK Glass Eels are a supplier of pre juvenile eels commonly known as glass eels for commercial eel farming and river restocking programs throughout Europe. Located in Gloucester, close to the river Severn that runs into the Bristol Bay on the west coast of England, owner Peter Wood contacted VAKI with a challenge to develop a high speed and accurate counter for these tiny creatures.

VAKI then teamed up with ACE to develop the counter for use in the wild and install it in one of ACE´s eel ladders. EA suggested we would test the new  counter at East Mills.

This is the first time we have modified one of our counters to count glass eels; the main challenge is the fact that they are almost transparent and only about 300mg in weight.
One of the prime objectives was to establish that the counter could “see” the glass eel, which to the delight of all proved to be a significant and surprising success.
