15th January to 15th October
Although the river Ness season opens on 1st February, the loch and the other rivers in the system open in early January and it is rare for fish to be in the river at that time. The fish start to be caught on a regular basis from March onward, but it is not until mid June/July that the main run of salmon and grilse begins.
The spring salmon have an average weight of 10lb, and in the summer months the grilse average 6lb. Towards the end of the season the average weight of late running fish in September and October increases, and it is not unusual for fish of 15 to 20lb to be caught.
On the Moriston the salmon fishing season starts on 15 January. The salmon come into the estuary beat which is just where the River Moriston runs into Loch Ness. The estuary is where most of the Moriston's salmon are caught as they will not go further up the River Moriston until late May. By June the fish reach the water below Inverwick.
On the River Garry the fish will only be at the Estuary until well into April unless the water temperature has been unseasonably warm. The fish stay here till the river warms up a little. The "fishy" water is
the few hundred yards from the turbine outflow to Loch Oich. This can be very productive and the fish can be large in size.
