153 Fish

• Is there any significance to the fact the John 21:11 specifically states that 153 fish were caught when Simon Peter cast his net where the post-resurrected Christ told him to?
  
  Why not say 'alot of fish'? Why specifically 153?
  
  
  
  153 'dots' (representing fish) make a triangle; possibly the trinity?
  
  ...or do I just have too much time on my hands? Tim
