Sperm performance limits the reproduction of an invasive fish

The Stickleback has a wide area of natural distribution, occurring in most inland coastal waters within the northern hemisphere. Here, they are found in a variety of shallow, heavily vegetated freshwater and brackish environments, including lakes, rivers, streams, and estuaries over muddy or sandy substrates. The stickleback is a prolific breeder and is expanding its range. Its impacts are a significant concern for our native aquatic ecosystems. During development, stickleback fish express Pitx1 in different parts of the body, including the pelvis. Most marine stickleback fish have a pelvis with a protective spine, but stickleback fish from certain freshwater populations have a missing or reduced pelvis.
