cgg 67-3 0815 hrs. - 1015 hrs. Total Trap hrs. = 34 Upper Shelf - (1) sinker was placed where I thought it would trap as many individuals as possible. See map Trap Depth (ft.) Number Captured [5] 2½' 6 Lower Shelf - Four lines were set at selected places, with four traps in each line. See below for depths. Lines I, III, IV were nearly vertical - Line II had weighted traps (except for floats), and rested against the western slope. Even "floats" of Line 4 was pulled beneath surface several feet - not enough traps to add another at this time. Traplines designated as I, II, III, & IV "a" is top trap, ("d" is lowest) Trap Depth (ft.) Number Captured Ia floata 0 Ib floata 0 Ic 10' 6 Id 20' 5 IIa floata 0 b 10 0 c 18 0 d 23 3
