<br />~ <br /> <br />1-3 <br /> <br />patterns of target larval fishes at the power canal intake. <br />3. Determine the level in the vertical water column used primarily by <br />the drifting target larval fishes at the intake point. <br />4. If T&E fishes occur, recommend guidelines and propose limits of <br />drifting target fish densities to USFWS and CDOW to determine the need for <br />fish screening devices at the power canal intake. <br /> <br />1.3 Tasks <br />The following tasks were performed to address each of the stated <br />objectives: <br />1A. Assess the species composition and calculate relative densities <br />(percentage) of adult and juvenile fishes in the vicinity of the project by <br />electrofishing and seining. <br />lB. Assess the species composition and calculate relative densities <br />(percentage) of young-of-the-year and larval fishes in the vicinity of the <br />project by using drift nets, dip nets and small-mesh seines. <br />2A. Calculate the densities (numbers per 1000 cubic feet) of fishes by <br />species drifting in the immediate vicinity of the power canal intake. <br />2B. Determine the daily and seasonal temporal drift patterns of the <br />larval fishes in the immediate vicinity of the canal intake. <br />2C. Relate larval fish drift in numbers per 1000 cubic feet to <br />temperature patterns in the vicinity of the project intake. <br />20. Calculate the sizes of drifting larval fishes, juveniles and adults <br />in the immediate vicinity of the project intake. <br />3A. Calculate the relative densities of drifting larval fishes in <br />numbers per 1000 cubic feet in the water column by using vertically-stacked <br />drift nets. <br />4A. Assess the need for fish screening or diversion devices at the <br />
