Please tell me what has to do with pickled fish, Easter egg and Good Friday?

I grew up not knowing anything about Pickled Fish and Easter egg. All I know about Easters is that Christians get together celebrate the life of Jesus Christ.  According to my knowledge Good Friday means a holiday celebrated by Christians, who believe in the death and rebirth of Jesus Christ, and the holiday is recognized as the historical day that Jesus died.

In our days most of the people are celebrating this day differently some by having family dinner which is Pickled Fish, it makes me wonder where this trend coming from. Everywhere in the malls and shopping centre you see Easter egg adverts, and in some grocery stores picked fish Buffet. I need your help can please someone  tells me what pickled fish and Easter egg has to do with Good Friday, maybe I’m later back.
