Book excerpt: This history of the salmon in the Great Lakes describes the decline and extinction of the Atlantic salmon in Lake Ontario in the 1800's; the failure to establish, by salmon culture, permanent or sizable populations of Atlantic or Pacific salmon in any of the Great Lakes in 1867-1965; and the success of plantings of coho and chinook salmon in the Great Lakes, 1966-1970 -- particularly in Lake Michigan.
Book Synopsis Alteration Tests of the Abernathy Salmon Diet, 1971 by : Laurie G. Fowler
Download or read book Alteration Tests of the Abernathy Salmon Diet, 1971 written by Laurie G. Fowler and published by . This book was released on 1972 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding trials using fall chinook salmon finglerlings were conducted at the Salmon Cultural Laboratory, Longview, Washington, during 1971 for the purpose of improving the Abernathy diet formula. The results indicated that cottonseed meal could replace a portion of the fish meal in the diet without reducing fish growth, but similar substitutions of wheat and corn gluten meal reduced growth. Fish growth was significantly increased when a diet containing 50 percent protein and 3,350 kcal per kilogram was fed as compared with a diet containing 45 percent protein and 3,350 kcal per kilogram. Soybean lecithin proved to be equal to soybean oil as a caloric source when fed at 2 percent of the diet. Two types of dried whey product with different levels of lactose content produced similar growth response. Reducing the dried whey portion of the diet to 5 percent did not affect growth, nor did methionine supplementation produce any effects. Anchovy meal was unsuitable as a replacement for herring meal.

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.

Book Synopsis Studies of Caloric and Vitamin Levels of Salmon Diets by : Laurie G. Fowler
Download or read book Studies of Caloric and Vitamin Levels of Salmon Diets written by Laurie G. Fowler and published by . This book was released on 1966 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the 1963 feeding trials may be summarized as follows: (1) Fish fed a vitamin-supplemented all-meal diet were maintained successfully for 24 weeeks with low mortality; (2) Rancidity in salmon carcass meal as indicated by a high TBA value reduced growth; (3) Fish that received meat supplements deposited more protein but did not have more efficient protein utilization than fish fed all-meal diets; (4) soybean oil meal was an inadequate replacement for cottonseed meal when fed as a component of the basal ration; (5) increasing the caloric level of a diet produced a sparing action on the protein requirements of the fish; (6) blood characteristics of fish from all diets were similar and satisfactory; (7) Fish fed with the meat-control diet had fatty infiltrated hepatic cells, which was not the case with fish fed the all-meal diets.

Book Synopsis Biology of the Crayfish Orconectes Causeyi and Its Use for Control of Aquatic Weeds in Trout Lakes by : Jack L. Dean
Download or read book Biology of the Crayfish Orconectes Causeyi and Its Use for Control of Aquatic Weeds in Trout Lakes written by Jack L. Dean and published by . This book was released on 1969 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sumerged aquatic plants limit the suitability for trout management of many shallow lakes in the Southwest. Control of these weeds has been achieved by the introduced crayfish Orconectes causeyi. The life history, ecology, and weed-control activities of the crayfish are discussed. Abundant crayfish populations occur over a wide range of elevations in permanent well-oxygenated ponds, lakes and streams where predaceous warm-water fishes are scarce. Weed control is proportional to the crayfish population and proximity of a rocky substrate which is preferred habitat. This crayfish is a tertiary burrower establishing relatively shallow burrows for hibernation and egg hatching periods. It has not damaged dams or irrigation ditches and has been compatible with local agriculture.

This book was released on 1967 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most steam-electric generating plants located near the ocean use sea water as coolant for their steam condenser system. During observations of coastal surface water temperatures off southern California in December 1962 with an airborne infrared radiometer, a noticeable rise in surface temperature was encountered when near warm-water outlets of generating plants, and heated discharge appeared to diffuse over the surface layer.
