Fish Community Comaosition Electrofishing, gill and trammel netting, and seining yielded one ~ herring, one trout, one pike, seven minnow, three sucker (and one hybrid), two catfish, one killifish, one live-bearer, one sea bass, three sunfish, and one perch species (Table 1). Electrofishing catch data showed flannelmouth sucker, carp, bluehead sucker, and channel catfish dominated the main channel fish community of riverine habitat sampled by UDWR (Table 2). In backwater habitats, seining catches ~ were dominated by red shiner and fathead minnow (Table 3). ]electro- fishing results of BOR from the river-lake transition zone indicated a fish community dominated by channel catfish and carp (Table 4). Back- waters in the transition zone were dominated by fathead minnow and red shiner (Table 5). ~ A total of 94 hrs of electrofishing effort was expended from April through September by UDWR. Spring standardized electrofishing accounted for 26.61 hrs; spring additional target electrofishing accounted for 34.30 hrs. Summer standardized electrofishing accounted for 31.43 hrs and additional target electrofishing for 1.66 hrs. During spring and summer, unidentified suckers (suckers that broke the ~ surf ace of the water but were not netted or identified to species) were the most abundant fish electrofished, followed by carp (Table _ 6). During spring the relative abundance of carp was greater than that of flannelmouth sucker, but during summer, the catch of flannel- mouth sucker exceeded the catch of carp (Table 6). - 13 -
