However, the elvers (glass eels) needed for aquaculture production are still dependent on catches from the wild, where production is continuously declining because of over-fishing and environmental degradation. Thus, artificial propagation becomes the key point for the sustainability of the eel aquaculture industry. The main problems for the artificial propagation include: (1) the insufficient knowledge on the mechanisms of eel maturation; (2) the unstable fertilization and hatching rates of eel eggs by long-term induced maturation; and (3) the unknown culture conditions for larval rearing. |
