Colorado Parks and Wildlife officials removed 14 massive, invasive carp from a pond at an Arvada park last week, more than 30 years after the fish were introduced as part of a national study. State officials were tipped to the presence of bighead carp at Jack B. Tomlinson Park by an angler, Colorado Parks and Wildlife said in a news release Monday. Agency officials removed the fish after stunning them with an electric current in the water Wednesday.
