Atari 2600 Game: Fishing Derby (1980 Activision) 

In Fishing Derby, your goal is to be the first of two players to catch 99 pounds of fish. Each player is on a dock at the top of the screen and you control the fishing line underwater. By moving the fishing line up or down, you can catch swimming fish. The deeper you go, the bigger the fish. When you catch a fish, you have to reel it in! To make the game more difficult, a shark continuously swims back and forth. If you have a fish on your line and it hits a shark, the shark will eat it and then you will have to catch another fish. There are two levels of difficulty and the game can be played by one person against the computer or two people against each other.
