Download or read book Tissue Changes in Puffers Exposed to Methoxychlor and Methyl Parathion written by Ronald Eisler and published by . This book was released on 1967 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adult northern puffers were exposed for periods up to 45 days to either 30 parts per billion (ppb) of the organochloride insecticide methoxychlor, 20, 200 ppb of the organophosphorous insecticide methyl parathion, or to a combination of 15 ppb of methoxychlor and 10, 100 ppb of methyl parathion. These concentrations will produce approximately 5 percent mortality in 96 hours under the conditions of the experiment. Profiles were constructed on the effects of each insecticide on blood and tissue components. The visual patterns provided by these profiles suggest a means of identifying unfavorable environmental conditions before the appearence of obvious morphological or physiological changes.

Download or read book Changes in the Fish Population in Lake Francis Case in South Dakota in the First 16 Years of Impoundment written by Charles R. Gasaway and published by . This book was released on 1970 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total number of adult fish in Lake Frances Case, a main steam Missouri River Reservoir, has declined since impoundment in 1952. Goldeye, channel catfish, and northern redhorse have probably remained the same; emerald shiner, white bass, walleye, and possibly flathead catfish have increased. The sauger population began to decline at about the time walleye numbers increased. Some species formerly present have become rare. Forage species in the reservoir were gizzard shad, emerald shiner, and yellow perch, but these were not present in large enough numbers to provide an abundant forage fish population.
