This book was released on 1976 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abundance increased and was highest in the lower third of the reservoir while it was filling, whereas it decreased and was generally highest in the upper two-thirds of the reservoir after it was filled. Abundance of species produced in littoral areas was greater wwhile the reservoir was filling -- particularly in years when spring water levels covered vegetation, fluctuated little, and were maintained through May or longer -- than after the reservoir was filled.

Book Synopsis Food of Alewives, Yellow Perch, Spottail Shiners, Trout-perch, and Slimy and Fourhorn Sculpins in Southeastern Lake Michigan by : LaRue Wells
Download or read book Food of Alewives, Yellow Perch, Spottail Shiners, Trout-perch, and Slimy and Fourhorn Sculpins in Southeastern Lake Michigan written by LaRue Wells and published by . This book was released on 1980 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stomachs of 1,064 alewives, 1,103 yellow perch, 246 spottail shiners, 288 trout-perch, 454 slimy sculpins, and 562 fourhorn sculpins from Lake Michigan were examined for food contents. Fish were sampled primarily from March to November and nearly all were caught at the bottom in the southeastern part of the lake near Saugatuck, Michigan. Pontoporeia was the most commonly reprented food item in the stomach contents of the fish examined, with immature midges, Mysis (a type of freshwater shrimp), copepods, cladocerans, fingernail clams and crayfish also being represented. Different species consumed different proportions of foods. Zooplankton was the principle food of alewives and spottail shiners, but was also consumed in small quantities by yellow perch and trout perch. Mysis was important to fourhorn sculpins, in addition to Pontoporeia. Immature midges were a major portion of spottail shiners and trout perch, also being consumed by alewives. Fish were often the most important food of yellow perch in the largest size category. Crayfish were a sizable portion of the diet of yellow perch on rocky bottoms, but sparingly on smooth bottoms. Spottail shiners also ate substantial numbers of fingernail clams.

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 Toxicity of Three Herbicides (butyl, Isooctyl, and Propylene Glycol Butyl Ether Esters of 2,4-D) to Cutthroat Trout and Lake Trout by : D. F. Woodward
Download or read book Toxicity of Three Herbicides (butyl, Isooctyl, and Propylene Glycol Butyl Ether Esters of 2,4-D) to Cutthroat Trout and Lake Trout written by D. F. Woodward and published by . This book was released on 1978 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two formulations of the herbicide 2,4-D (2,4-dichlorophenoxyacetic acid) - the butyl ester (BE) and the propylene glycol butyl ether ester (PGBEE) -- had 96-h LC50's to cutthroat trout and lake trout ranging from 490 to 1,200 microgram/liter in static tests. A third formulation -- the isooctyl ester (IE) -- was not toxic to cutthroat trout or lake trout at concentrations below 60.000 microgram/liter. The butyl ester (2,4-D BE) was slightly more toxic than 2,4-D PGBEE, and the toxicity of both esters increased as water temperature decreased.

Geographical abundance varied and were partly attributable to differences in fishing mortality.
