Catch your first sea trout with confidence

Catch your first Sea Trout in 3 steps

A simple, repeatable plan juniors can follow with help from a parent, coach or older angler.

  1. Step 1

    Expert-led sessions only

    Sea Trout fishing on rivers often takes place in low light or at night and involves strong currents. Juniors should only participate under the guidance of experienced game anglers or guides.

  2. Step 2

    Use appropriate river tackle

    Fly or spinning gear must match the river size and flow, with strong, knot-free leaders and barbless or de-barbed hooks to reduce damage.

  3. Step 3

    Respect strict rules and fish welfare

    Show juniors how important it is to follow local catch-and-release, season and method rules. Emphasise quick, careful handling and photos close to the water.

Tackle setups that work

Designed with juniors and fish welfare in mind. Start with an IDEAL or GOOD setup for easier casting and safe unhooking.

Fly Rod

Beginner tip: Focus on smooth casting and gentle lifting strikes, keep false casts to a minimum and always wear eye protection.

IDEAL

Rod: Fly rod rated to the correct line weight for the species and venue.

Reel: Matching fly reel with enough backing for the line weight.

Line: Tapered leader of 5–8 lb for trout and 8–12 lb for larger game fish.

Terminal tackle

  • ["Selection of flies"
  • "tippet ring or loop to loop connection"
  • "barbless or debarbed hooks"]

Extras

  • ["Polarised glasses"
  • "landing net"
  • "wading staff and belt if wading"]

Fly rod setup matched to line and leader for trout, grayling and other game fish.

Ultra-Light Lure Rod

Beginner tip: Stress local byelaws and seasons – many game fish must be returned carefully and some are protected.

GOOD

Rod: 6–7 ft ultra-light spinning rod (2–10 g).

Reel: 1000–2000 size fixed spool reel.

Line: 4–6 lb mono or braid with 4–6 lb fluorocarbon leader.

Terminal tackle

  • ["Barbless hooks where required"
  • "Appropriate local patterns or small spinners"]

Extras

  • ["Polarised glasses"
  • "Priest where legal"
  • "Rubber mesh landing net"]

Game fish like trout and grayling are usually targeted with fly tackle or light spinning gear.

About the Sea Trout

Sea Trout are migratory brown trout that feed at sea and return to rivers to spawn. They are often targeted at night with fly or spinner and are renowned for their strong fights.

Junior tip

Only target sea trout with an experienced adult and always follow local byelaws. Night fishing demands extra care with wading and safety gear.
