The four dominant fish species known in the United States as Asian carp are introduced invasive species.They all cause harm within their new environments. Specifically, the four most well-known species of invasive Asian carp are black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix), and bighead carp (Hypophthalmichthys nobilis).
The Carp Classic not only allows bowfishers a chance to shoot some fish, he said, but to educate people about the damage carp can do. The estimate is that there are about 400,000 carp in Moses ...
