Things to remember when feeding your freshwater eel:

Freshwater eels fascinate on virtually every aspect you can think about them. They determine their gender not by genetics but by water temperature – developing into males in salt water and females in fresh water. They’re bony fish, most closely related to the tarpon.

Eels are catadromous, meaning they live in freshwater rivers and spawn in the ocean. In October, sexually mature eels swim out of the Bay to the Sargasso Sea, an area of the Atlantic Ocean east of the Bahamas. In January, the eels spawn there, then die. Tiny eel larvae drift in the ocean for 9 to 12 months. During this time, larvae transform to the “glass eel” stage. Ocean currents carry the transparent glass eels thousands of miles to the U.S. coast. Before entering the Bay, the glass eels become pigmented. These brown eels, called elvers, are only about 2.4 inches long. Some elvers stay in the Bay, but most continue to swim many miles up the Bay’s rivers to fresh water. After a few months, the elvers transform into the adult “yellow eel” stage. Adults remain in freshwater rivers and streams for the majority of their lives. Once they reach sexual maturity, they return to the Sargasso Sea to spawn and die. American eels usually live for at least five years, though some eels can reach 15 to 20 years old.

Any ideas? Do we have freshwater eels in streams or lakes up here?

So, in short, please do not order unagi with your sushi! All of us freshwater eels thank you! The Anguillidae are a of that contains the freshwater eels. The nineteen species and six subspecies in this family are all in the genus . They are elongated fish with snake-like bodies, their long dorsal, caudal and anal fins forming a continuous fringe. They are fish, spending their adult lives in fresh water but migrating to the ocean to . Eels are an important food fish and some species are now but not bred in captivity. Many populations in the wild are now threatened and recommend consumers avoid eating anguillid eels.

A well-balanced freshwater eel diet consists of:

For other types of seafood, farm-raised stocks remain relatively stable when wild catches decline. But unagi, which hatch at sea but mature in freshwater, cannot be effectively bred in captivity, so farm-raised stocks rely on young eels, known as glass eels, which are harvested at sea, then raised to maturity at eel farms in China, Korea, and Japan.

Their fierce look, their snakelike elongated bodyand their general oddball attitude lure many fish keepers into buyingthem. But freshwater moray eels are not really what their common namepretends they are. Put into the standard community tanks they sometimesstart to reduce the stocking, but in most cases simply starve or diedue to various diseases. That's pretty sad, because under the rightconditions and with appropriate care they can be wonderful fish livingfor more than ten years. There is a number of further moray eel species, which can occur inbrackish water as well as in fresh water and therefore sometimes arecalled freshwater moray eel, but they are not seen in trade regularly,if at all. The most prominent example is literally a slender giant. reaches a length of almost 4 m and is rathera case for a indoor pool than a usual tank.
