Well being a pescarterian would mean that your only source of meat comes from seafood. You would need to eat more seafood to make up for other meats you aren't eating, plus take any food that you can eat that has proteins. Drink more milk to get vitamin D, which keeps bones strong and healthy. And most pescarterians eat either vegetarian meals or seafood meals, often switching back and forth between the two.
Hoe this helps!
