The appreciation of the clients results in different prices. Different methods of catching, transport and storage result in different qualities. But also for every location the first glass eels are caught in water that is much colder as the last glass eels from that location and therefore of better quality. The last few years the glass eels from England are most appreciated and next those from the north of Spain and the south of France. mixing of glass eels: Frequently we hear about mixing batches of glass eels. Low quality, cheaper glass eels from Morocco  or the mid of France are mixed with a good quality batch to lower the price and to make an offer more competitive. Even American glass eels are used, if available and cheaper. Although some people claim it to be normal that a few Anguilla Rostrata swim, together with the Anguilla Anguilla, to the European coasts, we think that is quite unlikely. size: When the glass eels have entered the river and swim upstream and the temperature rises in Spring, they start feeding because of the increasing quantities of micro organisms. So far all their energy came from their own bodyweight, so their weight had been decreasing. Therefore the last glass eels are smaller as the first glass eels, but also the catching location makes a difference. Glass eels from Spain are usually smaller as glass eels from England.
