Japanese eat grilled eel called Kabayaki

We eat grilled eel from the end of July to the beginning of August for relief from summer heat, because eel has good nutrition, like high-protein. Japanese cunsume 70% of the eel in the world. From 2003, the number of eels  is decreasing rapidly. Some institutes warn that Japanese consumption of eel is too high. Actually, we have succeeded in developing aquafarming of eel but there are some problems. It requires a stack of money in order to hatch eel eggs. Therefore, an eel business operator can't do perfect aquafarming of eel, so they take eel alive from the sea instead making it. Thats why natural live eels alevin are decreasing every year. Japanese people notice that eel are becoming expensive this year in this season because of the above reason. In japan, eel can be eaten as raw. However,  "Be careful, eel blood contains poison. Unfortunately I've never tried it. Someday I want to try to eat it.

[Good entry.  Eels eaten as food in general would be referred to as 'eel' ("We had eel for dinner.").  If I'm talking about the number of eels, especially in the sea, it is plural.  I can also use the singular form in an adjective ('the eel population")]
