It is their juvenile form that has turned an odd-looking, slippery fish into an expensive commodity. Elvers are now Canada’s most valuable fish. Driven by demand in Asia, glass eels can fetch thousands of dollars per kilogram (approximately a one-litre bottle full)—even sometimes more than $5,000 per kilogram. In 2022, fishers in Nova Scotia and New Brunswick earned $39 million from 7,557 kilograms of elvers harvested, according to DFO.
Yeah that kind of shit is nearly causing the European population of eels to disappear from rivers :-/
Too much fishing the larvae and there’s not much back to the continent.
