Yes, I’ve long known the explicative, “Holy mackerel!” but have never gone beyond that until moving to Eastport, where it’s commonly fished from the Breakwater pier. Previous postings here at the Barn reflect that.

That said.

1. It’s a small fish (around here, less than a foot long), oily like salmon, and to my eyes quite pretty.
2. For those casting with a rod and reel, it’s caught with four to six hooks on a line, on a good day all of them emerging from the water fully loaded.
3. Much of the haul here is either thrown back, as sport, or kept as bait for lobsters, or eaten smoked, pickled, or cooked fresh. Otherwise, mackerel don’t keep long. They’re bony, FYI, so they need to be fileted expertly.
4. Oily? They’re rich in healthy omega-3 fatty oils, a plus when it comes to cholesterol control. And, thanks to that oil, their beautiful scales do stick to the human touch. Oh, and the fish are low in dreaded mercury.
5. They exist in many species around the globe and are high on the menu of larger fishes.
6. They breed near the surface of the water, with a female releasing between 300,000 and a million-and-a-half eggs that float free in the open sea.
7. Ours travel in dense schools, roiling the water above.
8. They’re fun and easy to catch, from what I’ve seen, and a great target for young and new anglers. There is no size limit, harvest limit is 20 a day per person, no license required except in interior waters, however that’s defined.
9. They’re related to tuna and bonito. (Now we’re talking.)
10. There’s an art in the cast and in the jigging of the line while reeling it in.
