湧洞沼

湧洞沼 is a saltwater spot in 北海道, Japan, and the kind of place where tide does most of the work. The hours either side of high water tend to be the most productive on the coast here. At 湧洞沼, structure — reefs, drop-offs, headlands, harbour walls — concentrates baitfish, and predators follow. A good local rule: if the bait isn't where you expect it to be, the fish won't be either.

Fishing Techniques

• For Rainbow trout

  Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.

• For Cherry salmon

  Fish upstream, casting into likely holding areas like behind rocks and in deep pools, and retrieve with the current.

• For Big-scaled redfin

  Fish near submerged structures like rocks or fallen trees, as Big-scaled redfin often use these as ambush points; vary your retrieve speed to find what triggers bites.
