Manitoba Youth Angling Card

Since 2009, Fish Futures Inc. has facilitated a fish-themed artwork contest for children and the winning entry is featured on the cover of the Manitoba Youth Angling Card.  Each year highlights a different fish species and entries must include a short paragraph about the fish and its habitat.  Over 40,000 Youth Angling Cards are distributed for free to children in Manitoba each year.  

Lake Sturgeon – Spawning Behaviour

• Males mature at 18 to 20 years old and females mature at 20 to 24 years old. Compare to walleye that mature at 3 to 5 years and rarely live 20+ years.

• When mature, female lake sturgeon may spawn only once every four to six years. This means only a small portion of the population spawns each year, making them vulnerable to disturbance from overfishing or habitat loss.

• Lake sturgeon will return to where they were born to spawn.

• Spawning occurs in spring when the water temperature is between 13 to 15 degrees Celcius.

• Spawning habitat is 2 to 15 feet of fast-moving water – below waterfalls, rapids or dams – with sand, gravel, and boulders on bottom.

• The female approaches, males drum against her, releases eggs that mixes with their milt to fertilize the eggs, and they sink and stick to bottom.

• The number of eggs varies from 50,000 to 1 million - egg size, health and viability increase significantly with age.

• The lake sturgeon Hatch in about 7 to 10 days, and grow to about 20 cm (8 inches) by the end of the first summer.
