what is northern snakeheads preferred habitat
Abstract. The northern snakehead (Channa argus) is a large piscivorous fish that is invasive in eastern Europe and has recently been introduced in North America.n the winter (NovemberâApril), these fish moved to deeper water (~135 cm) with warmer temperatures, but habitat selection was weak at both scales. Northern snakeheads returned to shallower water (~95 cm) in the prespawn season (AprilâJune) and used milfoil and other cover.
In the winter (NovemberâApril), these fish moved to deeper water (~135 cm) with warmer temperatures, but habitat selection was weak at both scales. Northern snakeheads returned to shallower water (~95 cm) in the prespawn season (AprilâJune) and used milfoil and other cover.Habitat selection was the strongest at both meso-and microhabitat scales during the spawning season (JuneâSeptember), when fish preferred macrophytes and cover in shallow water (~88 cm).n the winter (NovemberâApril), these fish moved to deeper water (~135 cm) with warmer temperatures, but habitat selection was weak at both scales. Northern snakeheads returned to shallower water (~95 cm) in the prespawn season (AprilâJune) and used milfoil and other cover.
