Available in PDF, EPUB and Kindle. Book excerpt: The thermal regime of Lake Michigan is described on the basis of analysis of 1,671 bathythermograph casts made in 1954 and 1955. The beginning, duration, and geographic extent, and ending of thermal stratification were determined from 51 thermal profiles from all areas of the open lake.
Download or read book Biology of the Redtail Surfperch Amphistichus Rhodoterus from the Central Oregon Coast written by Donald E. Bennett and published by . This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on certain aspects of the life history of the redtail surfperch were collected along the central coast of Oregon, from April 1967 through April 1969. Annulus formation occured during February through June, usually earlier in young than in older fish. Mating occurred from late December to early January, and the young were born from July through September. The number of embryos per female ranged from 1 to 39 (mean 13.3) and increased linearly with the length and weight of the females. Food of the fish from the surf zone included crustaceans (by far the most important group in both frequency of occurrence and total volume) and (in order of decreasing importance) fishes, mollusks, and polychaetes. Parasites of the redtail surfperch were immature nematodes (Anisakinae) ; the digenetic trematode Genitocotyle acirra; the monogenetic trematode, Diclidophora sp.; and the copepods, Caligus sp., Clavella sp., and Argulus catostomi.

Heartwell and published by . This book was released on 1975 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Partial antibody characterization indicates that specific channel catfish immunoglobulins are macroglobulins with characteristics like those of most fish immunoglobulins and similar to those of human immunoglobulin-M.

This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spotted bass, Micropterus punctulatus, were studied in Bull Shoals Reservoir during 1966-71 to determine some of the environmental requirements for successful spawning and to estimate the reproductive potential of the species.
Download or read book Chemical Forest Fire Retardants written by W. Waynon Johnson and published by . This book was released on 1977 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicities of four chemical forest fire retardants, Fire-Trol 100 and 931 (ammonium sulfate, or polyphosphate with an attapulgit clay thickner) and Phos-Chek 202A and 259 (diammonium phosphate with guar gum derivative thickner) were determined by static and flow-through toxicity tests for fry and fingerling coho salmon and rainbow trout; fingerling fathead minnows, bluegills, and largemouth bass; and mature scuds. In static tests, Phos-Chek formulations were more toxic than either of the Fire-Trol formulations to scuds and all life stages of fish. In salmon and trout, fry were generally more susceptible than fingerlings to all formulations; yolk-sac fry were more susceptible than swim-up friy. Toxicities of all formulations to salmon and trout were similar at 6 to 11 degress centigrade. Un-ionized ammonia is believed to be the most toxic component of thes fire retardants.

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.

This book was released on 1972 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Morphological, physiological, and serological studies on 55 myxobacteria isolated principally from gill disease, tail rot, and other myxobacterial infections showed that a variety of myxobacteria occur in these infections. Athought there were different morphological types of myxobacteria, all strains from freshwater and estuarine sources were physiologically similar. Isolates from marine sources were physiologically less active than the other test organisms.

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.
