AquAdvantage salmon anadromous GM male salmon lack reproductive success and have a reduced number of surviving offspring. GM salmon's lack of fertilization success can be attributed to nest fidelity, quivering frequency, and spawn participation. Under simulated competition environments, 94% of siring occurred by wild-type salmon, while only 5.4% was attributed to GM salmon. This advantage allows more than twice as many wild-type offspring to be produced. Other characteristics that could cause wild-type males to be chosen more frequently could be the lack of growth of the kype, the hooked jaw of a male, and red coloration on anadromous males, which demonstrates sexual
King-of-the-salmon the pelvic fins, which are elongated with rows of pigmented swellings. Juvenile coloration is silvery with red fins and 3–5 dark blotches on the sides above the lateral line. Large king-of-the-salmon feed on copepods, krill, small pelagic fishes, young rockfishes, squid, and octopus, while small individuals feed on copepods, polychaete worms, and fish larvae. Off the coast of Oregon, juveniles have different diets depending on habitat. Offshore juveniles feed mainly on the hyperiid amphipod "Phronima", also taking small numbers of other amphipods, copepods, and free-floating fish scales. Inshore juveniles feed mainly on copepods and fish larvae. Known predators of small
