Onsella

Flowing through Aragón, Spain, Onsella is a river that suits anglers willing to walk a bank. Most fish at Onsella hold in identifiable lies — the same eddies, drop-offs, and shaded undercuts produce trip after trip. After heavy rain, Onsella can colour up and rise quickly; that's often when bigger predators come out to feed, but wading conditions get dangerous.

Fishing Techniques

• For Common carp

  Pre-bait the area with a similar bait you plan to fish with to attract carp and increase your chances.

• For Largemouth bass

  Vary your retrieve speed and lure presentation until you find what the bass are keying on, as their preferences can change daily based on weather and water conditions.

• For Wels catfish

  Fish near structures like fallen trees or bridges, as Wels catfish are ambush predators and like to hide.
