what fish?

And when they had brought their boats to land, they left everything and followed him. (Luke 5:11, ESV)

The disciples had just had the catch of their life and they left it to follow Jesus. They had just filled their boats with so many fish that they were sinking, they had never seen anything like it before during a lifetime of fishing, but all of a sudden fish didn't seem as important anymore. When confronted by Jesus' miracle, their thoughts do not turn to what they have gained, or what they could gain in the future. They are not overcome with excitement about the miracle, they are overwhelmed with their own sin (v8) and a desire to follow Jesus. 

What fish? 
We need to follow this man.
