You just need to follow these steps :

• Incline the fishing rod to the left (BEFORE to grab it), in order to get the fishs closer to your left hand.
  
• Attach the bait to the hook
  
• Put the hook into the water
  
• Wait until the hook starts to shake
  
• Remove the fish from the water until it stops to resist
  
• Take the fish and put it directly into the bucket (don't remove it from the hook)
  
• Enjoy and repeat
