r <br />Fisheries <br />Fish sampling within this section vas done a=clnsivel~ with entanglement <br />netting. Most of this sampling occurred during tLe spring period when more <br />personnel were available to adequately sample the extensive area. Bases on <br />previous experience in the Colorado River arm of the reservoir, it vas antici- <br />pated rare or endangered fish, particularly Colorado aquawfish, would be <br />congregating in this a rea prior to moving up the San Juan River. Through <br />extensive netting of the area, ve were hoping to capture several of these rare <br />fish. Since our experience in netting squavfish under reservoir conditions <br />have shown a strong correlation between mesh size and the girth of the fish, a <br />variety of mesh sizes vas used. Trammel nets were aced along with gill wets <br />since, again based on previous experience, traamel nets have been far more <br />effective in capturing the relatively large-bodied razorback sucker. loth <br />floating and sinking type nets were used so that a wider range of existing hab- <br />itat could be sampled.
