All the countless millions of elvers on the move are driven by the urge to find freshwater.
Rod not only sells cod and haddock but also elvers from Spain and caviar from the Caspian Sea.
Furthermore, huge quantities of eels of different species, live elvers as well as processed eels, are transported across the globe.
There is no evidence that recent low catches of elvers are due to pollution.
There is also a small commercial fishery for eels, both as elvers and adults, associated with the river.
The salmon, the elvers—the baby eels which come at this time of the year—and other fish are a very important source of revenue to fishermen.
