Smolt Trap on the River Nairn

A smolt trap has just been installed on the River Nairn to help measure the health of the fish stocks in the river.¬†Measuring the smolt output from a river is one of the best ways to determine the health of a salmon population.¬†“Smolt” is a life-stage of a juvenile salmon. This life stage occurs when a juvenile salmon begins its migration from freshwater to the estuary and adjusts to living in saltwater.¬†The smolt trap¬†will be¬†in operation from May to June and is checked daily by the FNLFT Biologist, Bob Laughton, and the Nairn Bailiff, Alastair Skinne,¬†with the help of local volunteers. The species, size, and weight of all fish caught are recorded before the fish is safely released downstream.

Great news for the river- in the first night of operation 88 salmon and 22 trout plus 1 large eel were caught!
