Landlocked Quinnat salmon fisheries are sustained by artificial stocking
Landlocked Quinnat Salmon are regularly released into various South Island lakes by Fish & Game. Aside from Lake Heron, in the Ashburton group, landlocked salmon fisheries in New Zealand are entirely supported by artificial stocking. These hatchery-reared salmon only live for a few years or so.
Landlocked salmon are the same species of Quinnat salmon that return as sea-run fish to our South Island east and west coast rivers over summer and autumn to spawn.
Landlocked salmon are released (stocked) into the lakes by Fish & Game. They do not spawn successfully before dying.
Landlocked salmon tend to swim in schools. The food supply for them in Lake Coleridge isn’t very plentiful so that don’t grow that big. Most reach only a kilo or two at most. Though anglers occasionally catch a larger one. The shoaling behaviour often leads to multiple hook-ups. There may be nothing happening for the shore anglers fishing the “picket-fence” then suddenly fish are hooked by several anglers at once!
Salmon trapped in lakes are voracious feeders and will tend to hit almost any lure that comes near them. For this reason, the catch in Lake Coleridge, for example, is dominated by landlocked salmon, followed by lesser numbers of rainbow trout, and browns making up a distant third place. Landlocked salmon will also readily take fluorescent lures at night that have been powered-up to glow with a touch. They are good fighters and make good eating – though possibly not quite as good freshly caught sea-run salmon which must surely rank as one of the best-eating fish in the sea!
Land-locked salmon are bright silver in colour with a blue tinge on their backs. This is a typical colouration of schooling land-locked salmon. They will readily take trolled or cast lures. It is not unusual for several anglers to hook-up in quick secession when a salmon school is encountered. It is important to keep casting when fishing from shore so that your lure will be in the water when a school happens along!
Rainbow Trout or Landlocked Salmon
They can look very similar when caught in lakes.
There are also landlocked salmon in Lake Coleridge, Heron, Sumner, Wakatipu, Wanaka, and Hawea.
