Download or read book Seasonal Abundance of Aquatic Invertebrates and Their Utilization by Hatchery-reared Rainbow Trout written by Harry D. Kennedy and published by . This book was released on 1967 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2-year study of the composition of bottom fauna, its seasonal and annual variations, and its utilization by hatchery-reared rainbow trout was made in experimental stream channels of Convict Creek, Mono County, California. Three orders of aquatic invertebrates, Trichoptera, Coleoptera, and Ephemeroptera, comprised 70 percent of the total bottom fauna. Terrestrial insects were an important food source between June and November but were absent from the diet between December and February. Forage ratios and frequency of occurrence of the primary food organisms is given. Post-hatchery survival of rainbow trout in small high altltude streams appears to be more dependent upon the physical condition of the trout at time of stocking than on a highly favorable physical environment.

Book Synopsis Changes in the Fish Population in Lake Francis Case in South Dakota in the First 16 Years of Impoundment by : Charles R. Gasaway
Download or read book Changes in the Fish Population in Lake Francis Case in South Dakota in the First 16 Years of Impoundment written by Charles R. Gasaway and published by . This book was released on 1970 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total number of adult fish in Lake Frances Case, a main steam Missouri River Reservoir, has declined since impoundment in 1952. Goldeye, channel catfish, and northern redhorse have probably remained the same; emerald shiner, white bass, walleye, and possibly flathead catfish have increased. The sauger population began to decline at about the time walleye numbers increased. Some species formerly present have become rare. Forage species in the reservoir were gizzard shad, emerald shiner, and yellow perch, but these were not present in large enough numbers to provide an abundant forage fish population.
