In AnWL, fishing is a very profitable way to earn your living.
Fish can be found in different sizes and different kinds. The more rare the fish, the larger profit it maes. Bigger sizes of the same kind will also earn more money. For instance, a Big Huchep will earn more than a Huchep. However, different kinds of fish are worth more than others. For example, a Yamame is worth more than a Big Huchep, because Yamames are more rare.
 Location, Location, Location
It's all about the location. There are different spots where you can fish in AnWL, which will get you more fish. The waterfall beside the excavation site is the most profitable spot, because the fish there are more high in value. However, the rarest fish, the Huge Sharshark, is found downstream. Although it is worth more, they are rare and extremely hard to find, meaning that fishing downstream isn't as profitable as fishing near the waterfall.
