Download or read book Biology of the Northern Pike in Oahe Reservoir 1959 Through 1965 written by Thomas J. Hassler and published by . This book was released on 1969 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variations in length, weight, and maturity of northern pike in Oahe Reservoir were associated with sex and year class. Females were larger and more numerous than males. Catches were dominated by the 1959 and 1962 year classes; the 1964 year class was missing. Annulus formation began in April and was completed by July. SInce impoundment, large year classes have been associated with a rise in water level above previous high levels in spring and continuation of the higher level though early summer.

Download or read book Species and Age Composition of Trap Net Catches in Lake Oahe South Dakota 1963 67 written by James A. Gabel and published by . This book was released on 1974 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-seven fish species were captured in Lake Oahe with trap nets in 1963-67. The catch was dominated by eight species in order of abundance: black crappie, bigmouth buffalo, white crappie, carp, river carpsucker, freshwater drum, smallmouth buffalo, and goldeye. Catch per unit of effort did not reflect changes in abundance of some of the species because of variation in environmental conditions. Frequency and strength of postimpoundment year classes were considered the best indicators of the ability of a species to adapt to reservoir conditions.

This book was released on 1974 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The body-scale relation, calculated length, length-weight relation, age at maturity, and sex ratio of 13 major species collected at Lake Oahe from 1963 to 1968 with trap nets and bottom trawls are described. Eight species grew at a faster rate than has been recorded in other Missouri River reservoirs: goldeye, bigmouth buffalo, smallmouth buffalo, white bass, black crappie, white crappie, walleye, and freshwater drum. Four species grew at rates similar to those recorded from other Missouri River reserviors: carp, yellow perch, northern pike, and sauger. One species -- river carpsucker -- grew slower than in other waters. Growth generally was excellent for all major species in the early years of impoundment (1959-62) but then declined. Although inundation of new lands was associated with rapid growth of fishes in the early years of impoundment, water level fluctuations during the growing season had no discernable effect on growth rate. Increased average reservoir depth, which decreased the amount of littoral area, was associated with decreased fish growth.

Download or read book Ecological Changes During the Transitional Years of Final Filling and Full Impoundment 1966 70 of Lake Oahe an Upper Missouri River Storage Reservoir written by Fred C. June and published by . This book was released on 1974 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information on ecological changes during the last years of filling (1966-67) and early years of full impoundment (1968-70) of Lake Oahe, a large storage reservoir on the Missouri River, is needed to determine both short- and long-term effects of the water regimen and to interpret changes in fish production. This paper gives synoptic data and trends on water discharge, water level, sedimentation, turbidity, transmissivity, temperature, specific conductance, dissolved oxygen, and plankton. Correlations indicate the nature of some apparent interactions between the plankton and certain of these environmental variables.

This book was released on 1969 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catch-effort data derived from gill net samples were used to estimate relative abundance, age composition, sex ratio, growth rate, survival rate, and relative year-class strength of northern pike, walleye, and sauger populations in Lake Sharpe, Missouri, S.D., during the first three years of impoundment (1964-1966.). Catches were generally highest in Oahe Dam tailwaters. Females were more numerous and larger at most ages than males.
