19.2 Fish Handling Guidelines
General fish handling guidelines are detailed below.
a) The drain(s) will be blocked or diverted according to individual project section drawings.
b) All fish will be removed from the project site through electrofishing, small seine and dip nets (various mesh size 1/8 – 1/4) and immediately transferred to aerated coolers located onshore.
c) Fish will be graded (size) and transferred in aerated tanks to sites upstream of the project area. Size separation is conducted to reduce damage and stress on the fish.
d) All transfer tanks will contain water from the original water body in order to reduce thermal or chemical stress on the fish.
