A serving being 4 oz. you should need 1200 oz for 300 people but considering there will be overeaters, you should probably bring 1400 to be sure to have enough.
The amount of fish you will need to feed 150 people will vary depending on what type of fish it is and how it is cooked. You should plan on about 150 pounds or a pound per person.

A person should have at least 1 20 pound turkey and 1 10 pound turkey in order to feed 20 people. There should be 1 pound of turkey for each person.
To serve 300 people, you will need about 9.375 gallons of potato salad. This is based on one gallon being 16 cups, so, if you figure 1/2 cup per serving, one gallon should serve 32 people.
600,000,000,000,000 boxes
