how do elvers breed and can they be bred in man made conditions?

Answer 1

The European eel was for a long time regarded as a very mysterious animal. Until quite recently no one had even seen a baby eel. People had all sorts of weird ideas about where eels came from. The ancient Greeks thought that eels had some strange way of reproducing, like scraping off pieces of their skin that then turned into adult eels.
We now know that baby eels are born in or near the Sargasso Sea in the western Atlantic Ocean - far from where we might expect to find them. When they hatch, the young fry do not look like eels, but like tiny curled up leaves, so it is not surprising that people thought they had never seen a young eel. At this stage they are called leptocephalii (you can see a leptocephalus in the figure on the right).
They then drift across the ocean to Europe, 5600 km (3480 miles) away, swept by Gulf Stream and the North Atlantic Drift. During the journey across the Atlantic they develop into elvers or glass eels, named because they are almost transparent.
When they reach the European coast the tiny eels swim up rivers, feeding and growing for the next 6-20 years. Once they achieve maturity, the adult yellow eel as they are now called, make their way back downriver, helped by the current. Their instinct to reach the sea is very strong. On wet nights the eels will even travel overland in the wet undergrowth.
At this stage they look quite different to the young eels that entered the river several years ago - their eyes are bigger, their heads wider and their bellies have turned silver or bronze (and so are sometimes called silver eels).
When they reach the sea the eels begin the very long, and still rather mysterious, journey back to the breeding grounds of the Sargasso Sea.
Fish that spend most of their lives in freshwater but migrate down river to spawn at sea are called catadromous.
So in order to breed eels in captivity first of all your method of holding them must be very, very, secure to stop them sliding off into the undergrowth and then you need to mount an expedition to the Sargasso Sea to obtain breeding stock. Good Luck in your endeavours.
