Winter feeding of channel catfish based on maximum air temperature
Dewey L. Tackett, Ray R. Carter, K.O. Allen
1987, Progressive Fish-Culturist (49) 290-292
A relationship between food consumption by channel catfish (Ictalurus punctatus) and maximum daily air temperature resulted in the development of a winter feeding program that has potential application for any geographical location....

Breeding birds and vegetation structure in western North Dakota wooded draws
C. A. Faanes
1987, Prairie Naturalist (19) 209-220
Populations and distribution of breeding birds occupying wooded draws were studied in a five-county region of western North Dakota during June 1982. Wooded draw vegetation was dominated by green ash, which occurred in 96% of the draws sampled. Chokecherry and juneberry were the most frequent shrub species. I recorded 49...
Discrepancies between ages determined from scales and otoliths for alewives from the Great Lakes
Robert O’Gorman, D. Hugh Barwick, Charles A. Bowen
R.D. Summerfelt, G.E. Hall, editor(s)
1987, Book chapter, Age and growth of fish
Discrepancies between ages determined from otoliths and those determined from scales were common and, sometimes, quite large in alewives Alosa pseudoharengus collected in fall 1983 from Lakes Ontario, Huron, and Michigan. Among fish with 'otolith ages' of 4 or more, the percentages having identical 'scale ages' were 1% in Lake...
Geochemical evolution of waters within the north coast limestone aquifers of Puerto Rico: A conceptualization based on a flow path in the Barceloneta area
A. J. Roman-Mas, R. W. Lee
1987, Water-Resources Investigations Report 86-4080
Water samples along a groundwater flow path in the Barceloneta area, Puerto Rico, were collected from wells screened in the Montebello Limestone Member of the Cibao Formation (artesian aquifer) and in the overlying Aguada and Aymamon Limestones (water table aquifer). The groundwater chemistry changes as water migrates from recharge areas...
Meeting future information needs for Great Lakes fisheries management
W.J. Christie, John J. Collins, Gary W. Eck, Chris I. Goddard, John M. Hoenig, Mark Holey, Lawrence D. Jacobson, Wayne MacCallum, Stephen J. Nepszy, Robert O’Gorman, James Selgeby
1987, Canadian Journal of Fisheries and Aquatic Sciences (44) 439-447
Description of information needs for management of Great Lakes fisheries is complicated by recent changes in biology and management of the Great Lakes, development of new analytical methodologies, and a transition in management from a traditional unispecies approach to a multispecies/community approach. A number of general problems with the collection...
Effects of freezing in and out of water on length and weight of Lake Michigan bloaters
Richard E. Sayers
1987, North American Journal of Fisheries Management (7) 299-301
The purpose of this study was to determine if freezing significantly alters the length or weight of bloaters Coregonus hoyi. Bloaters were collected from southern Lake Michigan and were frozen for periods of 2-200 d. Freezing in water caused a significant decrease in length and a significant increase in weight....
Feeding ecology of northern pintails and green-winged teal wintering in California
Ned H. Euliss Jr., Stanley W. Harris
1987, Journal of Wildlife Management (51) 724-732
The feeding ecology of northern pintails (Anas acuta) and green-winged teal (A. crecca) was examined from October through February 1979-81 in 4 major seasonal marsh types in the Central Valley, California. The esophagi of 262 pintails contained 72.3% plant seeds and 27.7% animal matter. The esophagi of 173 green-winged teal...
Estimates of plasma, packed cell and total blood volume in tissues of the rainbow trout (Salmo gairdneri)
W.H. Gingerich, R.A. Pityer, J.J. Rach
1987, Comparative Biochemistry and Physiology, Part A: Physiology (87A) 251-256
1. Total blood volume and relative blood volumes in selected tissues were determined in non-anesthetized, confined rainbow trout by using 51Cr-labelled trout erythrocytes as a vascular space marker.2. Mean total blood volume was estimated to be 4.09 ± 0.55 ml/100 g, or about 75% of that estimated with the commonly...
