In April and May 66,900 rainbow-trout eggs were collected at LakeLoveland and Twin Lakes. The loss on the Lake Loveland eggs dur-ing incubation was very heavy, amounting to over 54 per cent of thetake. This was attributed to the freezing of the eggs in the pan justafter they were taken. Quite a number of young trout were seen in thelake, and it is believed that much larger collections can be secured therenext season. In addition to eggs already mentioned, 25,000 rainbow-trout eggs werereceived from the California Fish Commission station at Sisson, Cal.,10,000 of them being reshipped to Neosho.
