Available in PDF, EPUB and Kindle. Book excerpt: Nifurpirinol (NFP), also know by code name P-7138, was tested for control of furunculosis, myxobacterioses, and vibriosis, and for effects on rainbow trout, coho, and chinook salmon under various conditions. Further tests are needed to verify the use of NFP for control of other bacterial diseases.

Book Synopsis Ecological Effects of Dredging and Dredge Spoil Disposal by : James Walter Morton
Download or read book Ecological Effects of Dredging and Dredge Spoil Disposal written by James Walter Morton and published by . This book was released on 1977 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to prepare a comprehensive review of the literature on the physical, chemical, and biological effects of dredging and spoil disposal in estuaries and to identify alternative spoil disposal methods. Specific objectives were to identify the most critical problems relating to dredging and spoil disposal and to summarize the progress made to date in solving these problems. Using literature search facilities, bibliographies, and communications with experts throughout the United States, about 520 scientific and technical articles on dredging and spoil disposal were screened. Information extracted from selected articles is included in this review.

Book Synopsis Reproduction of Smallmouth Bass, Micropterus Dolomieui, in Bull Shoals Lake, Arkansas by : Louis E. Vogele
Download or read book Reproduction of Smallmouth Bass, Micropterus Dolomieui, in Bull Shoals Lake, Arkansas written by Louis E. Vogele and published by . This book was released on 1981 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallmouth bass were studied in Bull Shoals Lake to determine the nesting requirements and reproductive capabilities of the species in a reservoir. Underwater observations were conducted weekly in five study areas during the spawning seasons of 1969-76. Length of spawning season was affected by the rate of water temperature rise during the nesting period. Active nests were found at ambient temperatures of 13.3-22.5 degrees Centigrade. Nest were generally on gently sloping rock and gravel bottoms, beside permanent objects such as rocks or sunken logs, and at densities of less than one per 100 m of shoreline.
Book Synopsis Lake Francis Case, a Missouri River Reservoir by : Charles H. Walburg
Download or read book Lake Francis Case, a Missouri River Reservoir written by Charles H. Walburg and published by . This book was released on 1977 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies conducted during the first 23 years of impoundment of Lake Francis Case indicated that fish abundance in the early 1970's was about half of that in the late 1950's. Of 39 species collected, 12 were abundant in the 1950's and 8 in the 1970's, but only 4 were abundant throughout the impoundment period.
Book Synopsis Abundance, Composition, and Distribution of Crustacean Zooplankton in Relation to Hypolimnetic Oxygen Depletion in West-central Lake Erie by : Roy F. Heberger
Download or read book Abundance, Composition, and Distribution of Crustacean Zooplankton in Relation to Hypolimnetic Oxygen Depletion in West-central Lake Erie written by Roy F. Heberger and published by . This book was released on 1977 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Samples of crustacean zooplankton were collected monthly in west-central Lake Erie in April and June to October 1968, and in July and August 1970, before and during periods of hypolimnetic dissolved oxygen (DO) depletion. The water column at offshore stations was thermally stratified from June through September 1968, and the hypolimnion contained no DO in mid-August of 1968 or 1970. Composition, abundance, and vertical distribution of crustacean zooplankton changed coincidently with oxygen depletion. Zooplankton composition shifted from mainly cyclopoid copepods in July to mainly cladocerans and copepod nauplii in middle to late August. We believe that mortality of adults and dormancy of copepodites in response to anoxia was the probable reason for the late summer decline of planktonic C. b. thomasi.
Book Synopsis Verification of a Model for Predicting the Effect of Inconstant Temperature on Embryonic Development of Lake Whitefish (Coregonus Clupeaformis) by : William H. Berlin
Download or read book Verification of a Model for Predicting the Effect of Inconstant Temperature on Embryonic Development of Lake Whitefish (Coregonus Clupeaformis) written by William H. Berlin and published by . This book was released on 1977 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eggs stripped from lake whitefish spawning in Lake Michigan were incubated in the laboratory at temperatures similar to those on whitefish spawning grounds in Lake Michigan during December-April. Observed times from fertilization to attachment of each of 21 developmental stages were used to test a model that predicts the rate of development at daily fluctuating temperatures; the model relates rate of development for any given stage j, expressed as the reciprocal of time (Rj), to temperature (T). The generalized equation for a developmental stage is Rj = abt ct[squared]. The model was used to predict the effects of small temperature increases (caused by a hypothetical waste-heat discharge) on the rate of development and time of hatching of lake whitefish eggs.
