Ranging in height from 4 to 6 feet, it will stretch 13 miles and consist primarily of concrete jersey barriers and chain-link fencing. Construction is underway and should be completed later this month.

In both areas the numbers went significantly high. Which displays the extent of the problem. ]]> 2016-12-08 18:15:27 UTC https://padlet.com/ix2xm/9p7w8rqrcmj3/wish/142638912 ix2xm https://padlet.com/ix2xm/9p7w8rqrcmj3/wish/142639328 Although eDNA tests are being done it is not always accurate, for example the test may say positive but the DNA could have come from other sources such as bilge water. It is a small connection but has a big outcome. ]]> 2016-12-08 18:16:30 UTC https://padlet.com/ix2xm/9p7w8rqrcmj3/wish/142639328 ix2xm https://padlet.com/ix2xm/9p7w8rqrcmj3/wish/142639634 eDNA was developed to help monitor invasive species since all fish release DNA into the environment.

The Shock Treatment is a system where a high voltage- powerful enough to stop the human heart, acts as a third barrier meant to provide redundancy. "Equipment in the control station produces a direct current that is delivered, in 4 millisecond pulses, through the electrodes, creating an electrical field in the water sufficiently uncomfortable for Asian carp."

Rotenone works by entering the fish's bloodstream via the gills and hampering cellular respiration.
