Default Swordfish daily patterns

Some of this was asked on another thread and I posted this as a response but thought would be an interesting thread on its own.

Compelling data we found couple years back on Swordfish daily patterns. Hope you find interesting as we did, given some great data.

Very cool, and definitive. Thanks for sharing. I wish that I lived near a place where I could target them at night...

Most folks go by the DAYTIME "typical" or "normal" 1600' foot range at least in the states (give or take). However, it is interesting in that there is some nuance to the depth depending upon geographic area and not just an anomaly. There are some folks I know catching Swords (daytime) WELL under that. From what I'm told that is directly correlated to some serious bait attraction. Whether they transit up to that bait vs "hole up" in that area is another issue.

Can anyone zoom in enough to estimate how long the average dive and ascent is? Thatís an awesome chart!

It's virtually an express route with no local stops

Also, it's apparent they stay in a zone of approx 50-100m during the day. At night, as you could imagine they are staying in the zone in, and around, the thermocline

The graph shows the swordfish following the Deep Scattering Layer up and then back down , which explains the consistency , not sure why that wasn't mentioned in the article .

Have been wanting to try day time swordfishing , I would really like to see a sword come from the deep and jump , then head straight back down . That has to be an awesome sight .

Honestly, it's pure awe inspiring. Truly. The only difficult part is the occasional heartbreaker when they do that 3 times over 4 or 5 hours and pull the hook. Ouch, but that's part of the game.

For us, each one is like "new car smell". Never gets old and feels like the first time.

I've seen Swords during the day on the surface. They're usually in a daze and you can get pretty close to them. Of course the Swordfishing boats from yesteryear harpooned them during the daytime.

I've read a few scientific papers on the Sword's movement. They do come up during the day and hang at a certain depth, sometimes not the surface (more of a Northern Atlantic phenomenon and 50-100 meters in warmer climates)

It's been speculated that they come up to water water to digest, Remember the water temps at 500meters is very cold and their metabolism will be slower. However, one of the papers I read said they also come up shallower during the day to regain oxygen. The waters in the deep are very low in oxygen and coming shallower allows them to make up their oxygen debt.

Iím going to put quit a bit of effort in getting one this year when I go on vacation in Sebastian. Would day or night off better odds?

Hey Ken,
That's a loaded question and different technique. I'd say night is "easier" as you have them up in search of dinner and not dealing with great depths. However, you still have to get on top of the right spots. For us, we dial in to where they are during the day so I would say easier for us is day. Maybe thats just because its more fun though.

At night you can play with the thermocline and get 3 different baits out so you have a good shot.

Here's another way to look at it - at least from our perspective. I would not make a trip out at night to just go swordfishing but we do make a deliberate day trip to do so.

The good news again is that there is a pattern as the chart indicates.

I also saw a sword basking on the surface off Cali coast. In a complete daze, was not interested in any offering, including live sardines. Oh well.

We sword out of the Sebastian and Stuart area. Personally, I prefer drifting for them at night given relief from the sun and anticipation of what may swim up into the light. The ocean was like a glass table at sunrise during one trip last summer when a massive blue marlin showed up and hung around the boat for a few minutes. We threw everything we had including a two pound live mullet at the marlin, but unfortunately, it was not interested in taking anything. As Tex alluded above, we always have a backup plan. We sometimes deep drop for tiles and snowys on the way back in if there is not a sword on deck. Ironically, we ended up limiting out on mutton say 200yds from the jetty during the blue marlin encounter trip after travelling around 200 miles without a bite.

Spotted 10- 12 swords during the day sunning themselves 9 of them in 350 to 400 ft of water. Guess none were tagged. Lol very interesting species I know of one last year that was close to 800 darted three miles of the beach.

That must have been the "Midnight Rambler" Sword. Incredible such a fish was that close to shore.
