Glass eels have an average weight of just over 16 grams and bigger eels might weigh 20kgs so a thousand fold increase in size. (Up to 40kgs in some cases). (New Zealand species in this case)

Global eel aquaculture is between 230,000 tons and 250,000 tons. Not counting wild catch.

The orc example is something between aquaculture and trapping, with eels being concentrated into pools and fed scraps. Then the larger ones are filtered out and eaten or smoked for later consumption.
