Natural HistoryNorthern pike spawn immediately after the ice leaves the water in spring, typically when water temperature is around 40 F.
In South Dakota, northerns are the first gamefish to spawn, usually during late March or early April. Male northern pike
typically mature at age two, and females at age three. A single large female may produce up to 600,000 eggs. Northern pike
lay their eggs on submerged vegetation in shallow water in the bays of large lakes, or at the mouth of a tributary or creek.
They do not create a nest for the eggs, nor do they provide any care for the eggs once they are laid. The eggs adhere to the
vegetation and will hatch in less than two weeks. Most of the eggs will not hatch successfully, falling prey to fungus,
invertebrates, or other fishes. The newly hatched fish (or fry), which are about one-quarter of an inch (7 mm) in length, use
their attached yolk sac for food during the first 7 to 10 days, and later feed on zooplankton in the water. Between feedings,
they return to some vegetation, attaching to it via a sticky patch on their heads. Eventually, they begin to feed on small fishes
and their sticky patch will disappear. Young northerns, under ideal conditions, may reach 10 or 12 inches (25.4 - 30.5 cm) in
length by fall
"I posted this because I thought that the amount of eggs one female can lay are amazing. I know every place is different as far as how and when the spawn occurs but the amount one lays is an accurate average I think. Enjoy this bit info and Tight Lines...
