Several fishing produces Japanese eel and are also brought up in captivity to meet the requirements. The overall numbers decrease and some scientists have suggested that there may be several reasons for this decline in numbers. The Japanese eel friction of the eel was designed for a very small area in the Pacific. Ocean currents will pick up eel in their larval form and allow them to reach the coast to travel inland to grow up. After several years in fresh water, the eels are betrayed and can travel back to friction to reproduce.

Adult eel Need to put eggs in an area with ocean streams that will carry the Japanese larvae eel in the right direction and very few places in open inOnce offers the right mixture of ocean currents. This may be one of the reasons why the eel population decreases, especially because some scientists believe that changes in the ocean salinity can confuse Japanese eel and lead them to incorrect places.

eels eat crustaceans they find on the bottom of the ocean, along with insects and bony fish. Some Japanese eel spend most of the time in salt water, while others prefer fresh water and are highly adaptable fish capable of mastering the environment that have different degrees of saltiness.

Aquaculture Operations for increasing Japanese eels on caught larvae or so -called glass eels, "the immature eel are preparing to move into fresh water because fish farmers were unable to breed in captivity. breeding opportunityAT and produce multiple eels. This, combined with harvesting eels for the commercial market, may be another reason for falling in the eel population.
