10 <br />Plankton nets (0.5-m diameter mouth, 0.565-mm mesh) were fished <br />daily in the main channel at bottom, mid- and sub-surface depths for <br />3-5 min at each depth. Nets became clogged with debris if towed for <br />a longer period of time. Tows were also made in quiet water and slow <br />back eddies near Gypsum Canyon. Ichthyoplankton samples were preserved <br />in 5-8% buffered formalin containing rose bengal dye for later exam- <br />ination for the presence of fish eggs and larvae. Eggs and larvae found <br />in the samples were measured with an ocular micrometer. <br />A 1.3-cm square mesh fyke net with 15.25-m lead was fished from <br />June 13 - July 12, 1981. The net was set with the lead perpendicular <br />to shore in shallow (0 to 1.5-m) water and checked approximately every <br />12 hr.
