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.

Available in PDF, EPUB and Kindle. Book excerpt: This study was based mainly on gill-net collections of yellow perch made during July and August 1971-79, in southern Lake Michigan at Grand Haven, Saugatuck, South Haven, Benton Harbor, and New Buffalo, Michigan; Michigan City and Gary, Indiana; Waukegan, Illinois; and Milwaukee, Wisconsin. Geographical abundance varied and were partly attributable to differences in fishing mortality.
Book Synopsis Proximate Composition and Caloric Content of Eight Lake Michigan Fishes by : Donald V. Rottiers
Download or read book Proximate Composition and Caloric Content of Eight Lake Michigan Fishes written by Donald V. Rottiers and published by . This book was released on 1982 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proximate composition (percentage lipid, water, fat-free dry material, ash) and caloric content of eight species of Lake Michigan fish were measured: lake trout, coho salmon, lake whitefish, bloater, alewife, rainbow smelt, deepwater sculpin, and slimy sculpin. Except for alewives, proximate composition and caloric content did not differ significantly between males and females. Although the caloric content of all species varied directly with lipid content and inversely with water content, an increase in lipid content did not always coincide with a proportional increasein caloric content when other components of fish composition were essentially unchanged. This observation suggests that the energy content of fish estimated from the proximate composition by using universal conversion factors may not necessarily be accurate.
Book Synopsis Acute Toxicity of Six Forest Insecticides to Three Aquatic Invertebrates and Four Fishes by : Herman O. Sanders
Download or read book Acute Toxicity of Six Forest Insecticides to Three Aquatic Invertebrates and Four Fishes written by Herman O. Sanders and published by . This book was released on 1983 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technical grade and field formulations of six experimental forest insecticides -- methomyl, carbaryl, aminocarb, trichlorfon, fenitrothion, and acephate -- were tested for acut toxicity against three species of aquatic invertebrates, (a daphnid, an amphipod, and larvae of a midge), and four species of fish (bluegill, rainbow trout, fathead minnow, channel catfish). Five of the six insecticides were highly toxic or extremely toxic to the daphnid, amphipod, and midge larvae. The sixth insecticide, acephate, was not toxic to invertebrates at concentrations up to 50 mg/L. Five of the insecticides ranged from highly toxic (methomyl to channel catfish) to relatively non-toxic (trichlorfon to fathead minnows); the sixth, acephate, was only slightly toxic to the fishes tested.
Book Synopsis Neuroendocrine Mediation of Photoperiod and Other Environmental Influences on Physiological Responses of Salmonids by : Hugh A. Poston
Download or read book Neuroendocrine Mediation of Photoperiod and Other Environmental Influences on Physiological Responses of Salmonids written by Hugh A. Poston and published by . This book was released on 1978 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manipulation of photoperiods, combined with modifications by other environmental conditions such as temperature and salinity, can alter growth, smoltification, and sexual maturation of salmonid fishes by way of a neuroendocrine pathway. The extent of responses of salmonids to environmental changes, however, is restricted by circadian endogenous metabolic rhythms that cannot be completely overcome by external factors. The success of the manipulation of photoperiod depends primarily on four factors: the daily length and the duration of the light treatment; the season and time of day during which fish are exposed to light; the age, sex, size and species of fish; and the type of physiological response under consideration. Although gaps remain in the available information, salmonids apparently need systematically changing, intermittent periods of darkness for optimum long-term stimulation of growth, reproduction, and migration.

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 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.
