<br />easy capture and enumeration of the majority of cripples and mortalities <br />in a given lot of fry. But the time and effort involved in doing this are <br />disproportionately large compared to the benefits realized. Secondly, the <br />efficiency of traditional feed training procedures at Clark's Fork Hatchery <br />were reaffirmed through this experiment. And finally, delaying the first <br />cleaning of rearing tanks by three to foUr days was determined to be highly <br />beneficial to fry survival. <br />Recommendations for the future include the following. <br /> <br />1) A discontinuation of the use of the fry sorter, since its use <br />produced such mixed results. <br /> <br />2) At a water temperature of 520F fall rainbow fry should be trained <br />to feed for 7 to 8 days before dumping, and brown trout should be <br />trained to feed for 12 to 13 days. <br /> <br />3) All fry should be given a three to four day adjustment period <br />in the rearing tanks before the tanks are cleaned for the first <br />time. <br /> <br />LITERATURE CITED <br /> <br />Booker, W.
