Decline of Wild Seed
The main reason that the aquaculture of Anguillid eels has become more popular in recent times is that the wild seed supply cannot support the demand of the consumer. Because of declining catches of both the European and Japanese glass eels, seed from the short-finned eels is at a commercial premium. The increasing pressure on eels has led to reduced recruitment of juveniles of angullid species which limits the industry and potentially leads to ecological impacts. Supply of seed to aquaculture operations of these eels relies solely on wild stocks of glass eels. These stocks are declining and there is now pressure being placed on the development of intensive eel culture technology. Anguillid eels cannot be reared from eggs in a culture setting, it is the glass eels caught from wild stock that are reared.
