I am a newbie to Fish Tycoon and spent sometime digging through the posts in the forum. I thought it might be nice for other newbies to have a string that just had hints and suggestions. We can post questions in another area.
OK. So here is my tip. First, remember that these are fish and not race cars! It will take time, so don't rush it. Work on building your cash first, and do the upgrades or research on the food, environment and advertising. It will make the game play much easier.
I would love to see links to support site, spread sheet offers, helpful hints and such in this string.
