During the spawning run, cisco feed heavily on their own eggs (Bangerter, 1962). Sigler (1962) states, "Bottom dwelling invertebrates are taken more commonly by the cisco in the winter months when the ciscos are in close to shore.'5 Unlike other species of cisco and whitefish, tins form has an extremely low incidence of parasitism (Perry, 1943). Numerically the Bonneville cisco is the most abundant species in Bear Lake (Sigler, L962 I. This was determined by gill nets set in open water flVn-y. L943) and on the bottom (Loo, I960; Sassier, I960). Distri- bution has been correlated with depth, temperature, and zooplankton abundance. Loo (1960) believed temperature exerted the controlling influence while Sigler and Miller (1963) stated that food was probably the prime factor. The most dense cisco concentrations are found along the steep east shore (Loo, I960). Perry (1943) found cisco widely distributed throughout Bear Lake except during the summer when they remained in and below the thermocline and seemed to prefer temperatures Less than 59° P. Using bottom gill nets, .McConnell et al (197)7 1 reported cisco numbers increased with depth. However. Loo (I960) and Sassier (1960) found cisco most concentrated at 50 and 100 feet, with lesser numbers at 150 feet; they reported a similar distribution for lake trout. Pood habil studies of Lear Lake game fishes have been few and the samples small. Smart (1958) examined 28 lake t rout stomachs and found, '" S i 11 were in the majority of slomachs except during De- cember and January when cisco was more common. This was due to the inshore spawning schools of cis
