Habitat & Range

Primary habitat: Deep Pacific/Atlantic.

The Sixgill Shark thrives across a wide range of saltwater environments throughout North America. Seasonal movements are driven by water temperature — fish tend to move into shallower water during spring and fall feeding periods, and push deeper or seek cover during the heat of summer and cold of winter. Understanding these patterns is critical to locating fish consistently across the season.

How to Fish for Sixgill Shark

Best bait: Whole Fish.

Technique: Deep Drop.

Match your presentation to the season and conditions. In clear water, downsize your bait and slow your retrieve. In stained or muddy water, switch to high-contrast colors and add vibration. Early morning and evening are the most productive windows during summer months. During spawning season, fish become highly territorial and will strike out of aggression as well as hunger.
