Before you sell fishes and boots, hang them on the wall and let the game run for a second, then go to buy mode and sell them. This "wall trick" raise the value about a third.

This is all good info. I only recently installed the Seasons EP, so I'm looking for tips like this. Thanks!

Here's another tip.

If you have a sim with no mechanical skill points and want them to start catching fish quickly, have them go to a comm lot with a pond and wait for several sims to arrive. Then have the sim start fishing and immediately start asking other sims to join. From my testing, they will start catching fish fairly quickly if there are a bunch of other sims also fishing with them. Even if they don't have many mechanical points.

I tested this with sims that had no points and sims that had up to two mechanical skill points. When other sims weren't invited, they quickly got too frustrated and gave up. But with other sims joining them, they got a boost to their social and the frustration was brief. But most importantly, they started catching fish. I did this to see if I could get my sims to fish for their food, no stocked refrigerator, only a grill. Now I know how to feed my new families super cheap.

Are there sunfish in TS2? I catch alot of those in real life.

Nope. far as I see, trout, rainbow trout, stuffed trout, bass... a full list on the wiki.

I think you need furniture all non-decorative furniture types on Kitchen(Dining does not count).

He meant "Hot Tub".

I wish you could swim in lakes/ponds

You can, there is a tutorial somewhere.
