Review of the environmental toxicity of quaternary ammonium halides

Autor: Jon C. Cooper

Publikováno v: Ecotoxicology and Environmental Safety. 16:65-71

This paper summarizes all available information on the environmental toxicity of quaternary ammonium compounds (QACs). Ten-minute contact kills of bacteria occur at 50–333 mg/liter. These chemicals are acutely toxic at approximately 1 mg/liter to i

Experimental Confirmation of the Olfactory Hypothesis with Homing, Artificially Imprinted Coho Salmon (Oncorhynchus kisutch)

Autor: Allan T. Scholz, Jon C. Cooper, Ross M. Horrall, Arthur D. Hasler, Dale M. Madison

Publikováno v: Journal of the Fisheries Research Board of Canada. 33:703-710

To test the olfactory hypothesis of salmon homing, fingerling coho salmon (Oncorhynchus kisutch) were exposed to low concentrations of an odorous synthetic chemical, morpholine during presmolt and smolting periods. Equal numbers of these fish were no

Homing of Rainbow Trout Transplanted in Lake Michigan: A Comparison of Three Procedures Used for Imprinting and Stocking

Autor: Allan T. Scholz, R. I. Daly, Ross M. Horrall, C. K. Gosse, Jon C. Cooper, Arthur D. Hasler, R. J. Poff

Publikováno v: Transactions of the American Fisheries Society. 107:439-443

We compared the homing ability of three groups of rainbow trout (Salmo gairdneri) stocked in Lake Michigan by different procedures. One group of juvenile rainbow trout was imprinted to a synthetic chemical, morpholine, during the presmolt and smolt s

Movements of Hudson River Striped Bass

Autor: James B. McLaren, Thomas B. Hoff, Vincent Lander, Jon C. Cooper

Publikováno v: Transactions of the American Fisheries Society. 110:158-167

The movements of age-II and older striped bass (Morone saxatilis), tagged during 1976 and 1977 within a 70-km section of the lower Hudson River, were determined from recaptures of fish within and outside the river. Movements within the river prior to

Recognition of Year-Class Dominance in Striped Bass Management

Autor: Jon C. Cooper, Tibor T. Polgar

Publikováno v: Transactions of the American Fisheries Society. 110:180-187

Major biological processes that establish the year-class strengths of Atlantic coast striped bass stocks (Morone saxatilis) are reviewed. Environmental factors seem to be the most important determinants of the initial population sizes. A general mana

Homing of Artificially Imprinted Steelhead (Rainbow) Trout, Salmo gairdneri

Autor: Allan T. Scholz, Jon C. Cooper

Publikováno v: Journal of the Fisheries Research Board of Canada. 33:826-829

Greater numbers of rainbow trout (Salmo gairdneri) exposed to morpholine as fingerlings as compared to trout left unexposed to morpholine as fingerlings homed to a stream scented with this odor (174 vs. 16). In order to locate this stream, the imprin

Electrophysiological Studies of Morpholine-Imprinted Coho Salmon (Oncorhynchus kisutch) and Rainbow Trout (Salmo gairdneri)

Autor: Jon C. Cooper, Arthur D. Hasler

Publikováno v: Journal of the Fisheries Research Board of Canada. 33:688-694

Two groups of coho salmon (Oncorhynchus kisutch) were exposed to a 5 × 10−5 mg/liter concentration of a synthetic chemical, morpholine, for 4 wk during the smolting period, while two corresponding groups were left unexposed (controls). All groups
