For several years, there's been an increase in the number of mackerel in the water. I'm going to share an experience with you.
Last summer, we were caught by a big storm out on the water. We had about four miles to cover on the water, and the mackerel rose to a depth of about five fathoms. It was a continuous line. We fished in several spots and the mackerel was very nice.
Often, you don't see it during the day. It swims up through the water column to the surface just before nightfall, then swims back down in the morning. When the sun rises, it goes down to the bottom. In the evening, it comes up because its stomach is empty, and it goes down in the morning because its stomach is full. It swims in the water column to feed. For that reason, it's impossible to catch it at that time.
