The approach
Start with the right question.
Look for places where fish can travel, rest, feed or use nearby depth changes.
In practice
Make it useful on the water.
Note what you can see directly and what remains a guess until a catch or measurement confirms it.
Keep learning
Connect the dots.
Use this guide as a starting point, then compare it with the water you're fishing, the tackle you're using, and your own observations. Good fishing knowledge grows through real practice.
