Yes ,they do like to think about fishing, but there are definite season trends in the fishing niche. Even with ice shanties and such, well, again if you are a warm-water fishermen, and your audience is warm-water fishermen, there is a seasonal trend. Stanley is in Texas and I'm in Alabama, and we can both assure you that there are seasonal trends. Whether those trends apply to this particular video, who know? However, it's curious that he asks this question right when fishermen in north American are switching to an active mode: more on that later.
That's why many fishing channels are dual sport. They switch to hunting amid autumn and winter. Many fishing T.V. shows have done this over the years because that's the seasonal trend. Just like gardening sells best in spring, although gardeners think about gardening all the time, there is a seasonal trend: things don't grow in winter because there isn't enough sunlight. The only thing to do is wait until the planet tilt forward again.
You simply cannot discount seasonal trends in the outdoors niche. This is one of the areas traditional YouTubers and teachers don't seem to understand. We deal with things that simple don't apply from other areas/niches. We have to pace ourselves at the pace of the planet itself. If it isn't the season for active fishing, most fishermen will do something else to take their minds off fishing until the next active season comes around. This always-on mentality of modern internet culture doesn't necessarily apply to fishermen and other outdoors sports/activities.
Warm climate people don't do cold climate activities. And passively thinking about fishing is different than actively planning for fishing. I've found that fishermen and hunters don't watch lots of videos when they are not in an active mode. Facts.
I can watch the weather and as soon as the first warm front of February rolls in here in the southeastern USA, that when you'll see fishermen at the boat dock,. That's also when you start seeing a slight uptick in views and subscribers. It happens without fail, every year. The season always peaks at about July 4th, then goes into decline for the rest of the year, wit a list uptick around the time school starts, but only briefly.
So seasonal trends are real in the fishing niche. They are real in other outdoors sports and activities, but you'll never hear that from the YouTube teacher types because they simply don't inhabitant that world, nor do they understand how those trends play into building and structuring your content to take the best advantage of those trends.
Also when those seasonal trend and uptick happen on the many sales start coming in not long after. Six years worth of data say this is fact.
