<br />3-4 <br /> <br />3.3 Data Recording and Analyses <br />All samples taken during this study were recorded on one of two types <br />of computerized field data sheets (see Appendix A). The drift net and dip <br />net samples were recorded on data sheet IAI which was used for larval fishes <br />identified in the laboratory. This included information on date, time of <br />day the net was set and retrieved, water velocity and depth, weather, cover, <br />habitat, substrate type, water temperature, and the specific information on <br />each fish captured (length and taxonomic features). Electrofishing and <br />seining samples and eventually all drift net and dip net samples were <br />recorded on data sheet IB', which is the standard field data sheet currently <br />used by the U.S. Fish and Wildlife Service in their river program. All data <br />were entered on a computer system to facilitate data management and <br />analyses. <br /> <br />~/. <br />
