Fish were electro-shocked and netted from a 15 ft <br />Achilles raft between 1998 and 2000. A l6-ft Hyside self-bailer raft was equipped for <br />electro-fishing in 2001 using the same Smith-Root electro-fisher, 5000-watt generator <br />and anode array mounted on a forward boom as in the three earlier years.
