After eighteen years of frustrating research, Japanese scientists have at last been bale to breed eels in captivity. To film part of this report the available light in a laboratory was electronically boosted thirty thousand times.
SYNOPSIS: Eels are an important food in Japan so this breakthrough by Tokyo. University's Professor Hibiya may have far reaching effects.
Fish breeding has been commonplace for many years, but eel-breeding habits are peculiar, as they take place in deep ocean far away from the lakes and rivers where they spend most of their lives. The simulation of the deep water environment has been the eel-breeder's problem. But now by using hormone injections to stimulate the female, the scientists of Tokyo University's fishery Laboratory have achieved success.
The hormone injection make the female eel swim closer to the male and at daybreak the releases her eggs. The male then fertilizes them. The university team are able to grow the eels form eggs to baby eels, on an artificial diet. Although the economics of this revolutionary method are not yet commercially proven, the future looks good fro large scale eel-farming.
