#DYK up to 10 or more sea lampreys may be present on a nest during spawning?! Sea lampreys usually spawn in the early spring (in tributaries to the lower Great Lakes) through mid-summer (in tributaries to the upper Great Lakes). When adults migrate into rivers, the males excrete pheromones to attract females to mate. The males and females build a nest together upstream in an area with gravel substrate. Sea lampreys use their suction-mouths to move rocks into a horseshoe shaped nest, with the open side facing upstream. During the next few hours or days, the sea lampreys will alternate bouts of rock moving, tail fanning (to clean the nest), and spawning. To initiate the act, a male suctions onto a female’s head then coils around the female and rubs his rope (i.e., the ridge of tissue that male sea lampreys develop on their back) on the abdomen of the female, encouraging her to release her eggs. As the eggs are expelled, the male fertilizes them and the eggs fall into the spaces among the rocks in the nest, where they are protected. One female can produce up to 100,000 eggs! After spawning, the adults will die, providing nutrients for their larvae as their bodies decompose. If you want to learn more about invasive sea lampreys in the Great Lakes and how they spawn, check out our website: www.sealamprey.org. And be sure to keep watching for our weekly #DYK posts!

Field of View is a crucial factor in choosing the right surveillance camera for your needs. It determines the area a camera can capture, measured in degrees. 📐 A wider FOV covers more ground, perfect for open areas, while a narrower FOV focuses on details, ideal for identifying faces or licence plates. Understanding FOV helps you tailor your security setup for optimal coverage and clarity.
