The female releases her eggs while the male fertilizes them externally. After spawning, the adults return to their regular habitats, leaving the eggs to develop and hatch. The young longnose suckers then begin their journey, growing and adapting to their environment.
After mating, the female lays her eggs, which are fertilized by the male outside the body.  The parents then go back to their normal environments, allowing the eggs to develop into larvae. These larvae grow and adapt to their surroundings before becoming adults.
