<br />A census using returned tags to determine
<br />migration of stocked fish and their appro%i-
<br />mate growth. Rainbow and brown trout were
<br />compared for winter survival, catchability,
<br />migration, and weight on numerical returns.

<br />Results of stream census conducted during the

<br />recommendation that whitefish take could be
<br />liberalized and that year-round angling was
<br />reseonable.

<br />This report presents observations on the summer

<br />from plants of kokanee salmon and rainbow
<br />trout in Skaguay Reservoir, Colorado.
<br />Colo. Div. Game, Fish and Parks. 16pp.
<br />A study to determine the existing conditions
<br />important to the survival of fish was imple-
<br />mented. Kokanee salmon and rainbow trout were
<br />stocked and their population numbers over a
<br />period of 5 years were noted. A high return
<br />to the creel was sought for a game-fish species
<br />able to compete with the forage species
<br />present. The use of kokanee fry appeared
<br />successful.

<br />Documents the introduction and present status
<br />of whitefish in the Cache la Poudre River.
<br />Reasons for greater abundance in certain areas
<br />are discussed. It is suggested that popula-
<br />tions continue to be monitored and that studies
<br />of trout-whitefish interrelationships be con-
<br />ducted.
