Happy Fishing!!

• Each person represent the head of their family• You all are fishing for a public lake with fish that feeds your

family.• You only get one chances to fish a year.• You may take as many fish as you would like. However –

catching one fish or less – your family will starve.• Every fish you catch after two fishes – you can sell for

profit.• The fish will reproduce in the lake once a year. Each fish is

able to spontaneously make two new fish.• When your group runs out of fish, the game is over for you.
