Okay it says to start fishing:
Puzzle 3 is completed by cleaning up the debris on the beach. Completion of this puzzle is required before your villagers will be able to fish in the ocean (which also requires Level 3 of Harvesting). Drag a villager to the debris field and they will begin cleaning up the beach.

I cleaned the debris but what does it mean by Level 3 Harvesting? Is that Master Farmer?

It should read Level 3 of Farming! That technology is called Harvesing in Village Sim (the Palm version of Virtual Villagers), and I forgot to change it. I've updated the guide to correct that error.

So level 3 is Master? When he becomes level 3 will he be automatically be able to fish?

Level 3 refers to Farming Technology - go to the Tech Screen in your game!

Erg... well I STILL only have level 1 Farming... I also only have 3027 tech points and 618 berries! So if I got level 2 farming where else could I get food?

Level 2 of Farming Technology will allow your villagers to grow crops.

Okay! Well I sorta did a bad thing... I just got level 2 in construction but now I'm still running out of food... I'm finding myself starting over veeeeery soon

That's one way to figure out a successful strategy!

Okay well I started over! I'd like you to help me because you know alot! So I have a girl foraging, someone dude researching, another girl building, and two people cleaning the beach up. I'm asking you, What should I buy with my tech points first? Farmig, Fertility, Science, Construction, Spirituality, and I forget the other one? Which one is most important to get to level 2 first?

Well, for starters, I never have my villagers clean the beach or build the first hut until I have enough tech points to purchase the next level of Farming Technology (unless I'm doing some special testing). They don't need a clean beach until they're ready to start fishing, and the berry bush won't comfortably support more than about 7 villagers - so they don't really need that new hut just yet.

I usually put one or two villagers to work gathering berries and everyone else gets plonked down at the research table. As soon as they've got enough points, I always buy Farming tech first. Different people have different strategies after that (you can search the forums and find many discussions about it), but basically everybody gets farming first.
