Freshwater eels are very valuable fish species, principally in Asian and European countries. Eel farming is a capture-based aquaculture activity, based on the practice of collecting juveniles’ eels from the wild and on-growing in captivity to marketable size using aquaculture techniques. Due to their complex life cycle, research efforts have not yet managed to produce glass eel at a commercial scale. Dr. Erfan Shahkar, Nutritionist at Blue Aqua International Ltd explains how, after a series of efforts, Korea got the breakthrough to produce two Japanese glass eels in 2012.
