Yes, there is fishing, just as there is in previous VV games. Like VV2, you have to solve a puzzle to gain access. There is a step-by-step approach to food sources in the Official VV3 Strategy Guide, or (if you only want hints) here are some things to consider when developing your strategy:

Growing the population too large and too soon will create a food crisis. The initial food supplies in all VV games are limited and won't support a very large population. The trees and honey will replenish slowly, but never to the amounts that appeared in the initial harvests. In VV3, if you grow the population beyond about 10-12 villagers before you have an unlimited food supply, you will need to hunt mushrooms a lot to prevent starvation.

Some things you can do to help get extra food:

- Make sure you are using your chief to make extra food every day.
- Hunt mushrooms, especially when it's raining.
- Have all of your working-age villagers do research when there is no food left to harvest. This will get you much-needed tech points.
- Make sure you check what each village tech does for your tribe (click the "?" next to each Buy button). Some are more helpful than others early in the game.
