23 <br />area were more protected due to their relative exposures. This helped <br />minimize disturbances from the storms. Razorback suckers failed to <br />return to the Six Mile Coves area during the remainder of the 1983 <br />spawning season but continued to spawn in the more protected shoreline <br />areas elsewhere in Lake Mohave. Netting was continued in Tequila and <br />Nine Mile Coves for the remainder of 1983 where spawning activity <br />followed the pattern similar to that in 1982. <br />The large mesh nets used for routine sampling were selective toward <br />large fish. Experimental trammel and gill nets were used on two sampling <br />dates (Nov. 1982 and Jan. 1983). There were some differences in"the <br />sizes and numbers of fish caught in the two types of nets set in <br />November. The experimental nets were set for 24 hours. Trammel nets were <br />pulled after eight hours due to large numbers of razorbacks being taken. <br />Only 2 species of fish, threadfin shad (Dorosoma petenense) and rainbow <br />trout were too small to be taken by the regular trammel nets. Both <br />species were taken at night in the experimental nets after trammel nets <br />had been pulled. The rainbow trout were nearly identical in size and <br />appeared to be from a recent stocking. Similar nets set in January 1983 <br />caught nearly the same types of fish. Small sunfish were not collected <br />in sampling and were not present in the shallow water until late April <br />near the end of the spawning season. The species composition and <br />relative abundances of fish caught in the trammel nets seem to reflect <br />those present in the sampling areas. <br />4.3 Length and Weight Distributions, Condition Factors, Sex Ratios, <br />and Disease <br />Lengths.and weights of razorback suckers captured during this study <br />are summarized in Table 2. Total lengths were similar to those reported
