Tuna!!!

My mother used to live near a port when she was young, so she loves seafood. Everytime I back home during the holiday, she always welcome me with Sashimi. I love seafood and this welcome dinner very much!! But there is a bad news. I've read a news article that said "The number of tuna fish is decreasing, and by 2007, we could have only half amount of tuna". The reason of decrease is that, because people cought the fish too much... Well, not only me and my mother but also many Japanese people love tuna fish. I hope to be able to see tuna and other fish at the table in the futuer too.
