<br />A. study oi age and gruwth rates of four species oi fish taken from thc Mis-
<br />sumi HiveI'. hetween Hulter Dam and Cascade, Montana, was made during tlw
<br />SllI1llll''rS oj 1')41) and 194<), Fuur hUlldred and seventy-eight rainbow trout 127
<br />hr,Jwn trout, H7 longnose suckers, and 223 western white suckers were e~am-
<br />1I1ed. Age gruups of rainbow trout ranged from I to VII; brown trout, I to
<br />IX; longn,'se Slickers, III. to V.III;, western white suckers, I to VIII. Age
<br />grollP 11 was rno,'t predumlllant III rall1bow and brown trout, group VI in long,
<br />nus". Slickers, aud group III in westcrn white suckers. Greatest growth was
<br />;~llanll'd dUJ"lng thc sec.ond y"ar ill rainbow and brown trout, and during the
<br />!'.rsl and tfllrd years tor .Iunj.(nose and western white suckers, respectively.
<br />I rout gruwth IS more ra'llld than sucker growth. The majority of trout were
<br />represented In age groups I-I If, while suckers w('re predominantly repre-
<br />sellted in age groups IV-VIII. Coefficient of condition for 4B1 rainbow trout
<br />was 37.2 and i or I] 7 brown trout was 34,6.

<br />
<br />During tlie SlIJ11nll:rs of 1948 and 1949 a lislwries survey was COII-
<br />ducted on a section of the l\'lissouri River hetween Holter Darn and Cas-
<br />,ark, Montana. Since no previous tisheries investigations on this pan
<br />of the rivtr were kllown to the writer, a study oi the g-rowth charac-
<br />Inistics oi Some oi the more important species was undertaken to
<br />assist in an evaluation of management prohlems.
<br />
<br />Rainhow trout (-S'n/lllo !laird/lcrii) and brown trout (Sa/lllo IrUltll),
<br />which are the most ill1Jxlrlant game fish in this section of the river,
<br />and longnose sucker (CatosIO/Jllls ra/ostolllttS) and western white Slicker
<br />(Ca~ostol/Jus rOllllllc;rsolmii sHcklii), two of the more important forage
<br />speCIes, were examllled.
<br />
<br />There arc 35 milt's of stream between Holter Dam and Cascade. The
<br />upper 15 miles 0 f this stretch t ra verse a narrow valley of meadow
<br />la~d. Below this area the river tJrst flows through a canyon for 8
<br />mdes and then through :.In open valley of farm land for the remain-
<br />ing distance. The gradient in this section of river is relatively low with
<br />:.I fall of 3.1 feet per mile. In other respects the river is similar to
<br />other streams of the region.
