Exempel på hur man kan använda SMOLTS i en mening

• The hatchery's mission shifted to preserving the species and its genetic diversity through the development of eight broodstocks derived from smolts, anadromous adults, and residual populations.
• The state-of-the-art Robertson Creek Fish Hatchery is the most successful hatchery on Vancouver Island, producing chinook salmon, coho salmon, and steelhead smolts.
• The construction of the dam created reverse currents (currents flowing upstream) in the Metolius Arm of Lake Billy Chinook (a reservoir created by the formation of the dam) confusing anadromous smolts and preventing them from navigating seaward.
• Pacific salmon return to the marine nearshore starting in June, and finish as late as December, dependent upon species and run timing, whereas the smolts typically outmigrate starting in April, and ending in late August, dependent upon species and run timing.
• Beaver may be beneficial to efforts to restore salmonids in Alameda Creek as beaver ponds benefit oversummering salmonid smolts by raising the water table which then recharges streams in the dry summer season and also by providing perennial deep pools when streams are only seasonal.
• Large numbers of lesser sandeel (Ammodytes marinus) available as prey for marine fishes enhance the survival of Atlantic salmon smolts (Salmo salar) as they leave the Tana river, North Norway.
• About 1 1/4 miles below Gumboot Creek is the Imnaha River Acclimation Site and Weir, where adult Chinook salmon are collected and smolts are released for the hatchery supplementation program.
• Modern commercial hatcheries for supplying salmon smolts to aquaculture net pens have been shifting to recirculating aquaculture systems (RAS)s where the water is recycled within the hatchery.
• Another study in 2019 established that survival rates for smolts passing through the turbines and tailrace screens at Invergarry power station were 86 percent, and so the inlet screens, against which they were being squashed by the current, were removed in 2020, and the design of the tailrace screens was altered to improve survival rates.
• In addition, there is a freshet gate in the barrage, and when there is a build up of smolts above the barrage, a smolt freshet is released through the gate, to assist passage of the smolts to the sea.
