Spawning occurs annually in southern areas, every other year in Great Slave Lake, Northwest Terrritories, and only every other year in Great Bear and some other lakes of the arctic (Ref. On occasion, as many as seven males and three females may engage in a mass spawning act (Ref. The act is repeated until the female releases all her eggs (Ref. The eggs fall into the crevices and the spawners disperse. One or two males approach a female, press against her sides and quiver. Store in the refrigerator - or in cases of larger batches, in an insulated cooler - for at least two hours, but overnight. Make sure all the fish is covered with brine. Thirty trout came in to Miller’s Landing. Mix the salt and brown sugar into the water and stir until both ingredients are dissolved. During and following courtship, the males attempt to spawn with the females. Veteran Bass Lake guide Mike Beighey of Bass Lake Fishing said, The Bass Lake Trout Derby was a tale of two days. Females arrive a few days later and are courted by the males. During winter, when most lake waters are a uniform. Males reach spawning beds first and spend some time cleaning the rocks. Lake trout inhabit deep, cold lakes, and are strongly influenced by annual temperature events within a lake. During the day the fish are more or less dispersed away from the spawning beds but return in considerable numbers in the late afternoon (Ref. The spawning act occurs mostly at night, with peak activity between dusk and 9 or 10 pm (Ref. Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae Canadian scientists at IISD-ELA have discovered that certain lake predators are altering their behaviour due to climate change, revealing what the future. Utilized as a food fish, its flesh is usually of a yellow or creamy color but may be anything from white to orange (Ref. Lake trout are highly susceptible to pollution, especially from insecticides (Ref. Such plankton-feeding lake trout grow more slowly, mature earlier and at smaller size, die sooner and attain smaller maximum size than do their fish-eating counterparts (Ref. They are a slow growing fish with a low reproduction rate. Although lake trout generally feed on a variety of organisms such as freshwater sponges, crustaceans, insects, fishes (with a preference for ciscoes), and small mammals, some populations feed on plankton throughout their lives (Ref. As their name implies, Lake Trout live almost exclusive in lakes, rarely in rivers. A solitary wanderer, the extent of their movements apparently limited by the size of the lake and individual (Ref. Occurs in shallow and deep waters of northern lakes and streams and is restricted to relatively deep lakes in the southern part of its range (Ref.
