http://en.wikipedia.org/wiki/Silver_carp google ir t.t. In North America Silver carp were imported to North America in the 1970s to control algae growth in aquaculture and municipal wastewater treatment facilities. They escaped from captivity soon after their importation.[5] They are considered a highly invasive species.[6] Silver carp together with the closely related bighead carp often reach extremely high population densities and are thought to have undesirable effects on the environment and on native species.[7] By 2003 silver carp had spread into the Mississippi, Illinois, Ohio, and Missouri rivers and many of their tributaries in the US. They are now (August 2009) abundant in the Mississippi River watershed from Louisiana to South Dakota and Illinois, and are close to invading the Great Lakes via the Chicago Sanitary and Ship Canal.[8] Navigation dams on the Mississippi River seem to have slowed their advance up the Mississippi River, and until late November 2008 silver carp had not been captured north of central Iowa on the Mississippi.[9] Dams that do not have navigation locks are complete barriers to upstream natural movement of silver carp, and it is important that fishermen do not assist this movement by the unintentional use of silver carp as bait.[10] The silver carp is also called the flying carp for its tendency to leap from the water when startled.[11] They can grow to over 40 lb (18 kg), and can leap 10 ft (3 m) in the air. Many boaters traveling in uncovered high-speed watercraft have been injured by running into the fish while at speed. In 2003 a woman jet-skiing broke her nose and a vertebra colliding with a silver carp and nearly drowned.[12] In another example, a teenager's jaw was broken by a silver carp while being pulled on an inner tube.[13] Water skiing in areas where silver carp are present is extremely dangerous.[14] "B.A.@work" <andriuiTRINK@hotmail.com> wrote in message news:in406u$t7s$1@trimpas.omnitel.net... > 2011.04.01 09:57, Kuujis@work rašė: >> Man irgi tiesą pasakius... =) >> >> "Blynas" <blynasTRINTI@gmail.com> wrote in message >> news:in3mr6$efl$1@trimpas.omnitel.net... >>> Sudomino.
