Estuary fishing for sea trout has been carried out for generations. The most common method was to use sand eels or mackerel strips. In recent times, fly fishing has become more popular. Indeed Michael Rogan's Gadget was probably the original estuary sea trout fly. There are many estuaries where sea trout can be fished with a fly. In the estuary we are fishing for feeding sea trout. This calls for somewhat different tactics to those employed on fresh water.
To begin with, the rise and fall of tides have to be taken into account. On big estuaries, when the tide is rising or full, the shoals of sea trout can be widely dispersed and notoriously difficult to locate.The hour before and after low tide can be most productive. Then the fish are confined to the main channel and easier to find. The tackle used is much the same as on the lough.
A single-handed rod, AFTM7 line, floating and intermediate, six to eight pound leader and some flies which differ greatly from those used in fresh water. Most popular appear to be the streamer types, such as the Baltic Special, Parson Tom, White Lure, Black Lure and the Gadget. For spin rods rapala and tobys are known to catch sea trout.
