Author: Thermal Characteristics of Lake Michigan, 1954-55
Author: John F. CarrPublisher:
ISBN:
Category : Michigan, Lake
Languages : en
Pages : 148
Book Description
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.
Biology of the Redtail Surfperch (Amphistichus Rhodoterus) from the Central Oregon Coast
Author: Donald E. BennettPublisher:
ISBN:
Category : Fishes
Languages : en
Pages : 32
Book Description
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.

Book Description
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.

Chemical Forest Fire Retardants
Author: W. Waynon JohnsonPublisher:
ISBN:
Category : Acute toxicity testing
Languages : en
Pages : 16
Book Description
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.
