Brown Trout fly box

A realistic Dutch trout fallback. Do not force a wild-river-trout identity here; keep it as a stocked stillwater and lake-trout pack.

About this water

Niche coastal sea-trout fishing along the Dutch North Sea coast. A specialist pursuit for dedicated anglers — not a mainstream Dutch fishing activity. Night fishing with streamers and baitfish patterns from beaches, harbour walls and estuarine margins. VISpas (national fishing licence from Sportvisserij Nederland) required. Limited but real sea-trout presence in North Sea coastal waters.
