This book was released on 1981 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of the organophosphate insecticide Abate three times (at about monthly intervals) to duplicate 0.04 ha earthen ponds at 18 g/ha (4 micrograms/liter) -- the recommended application rate -- and 180 g/ha (40 micrograms/liter) caused no mortality on blugills. In ponds treated with 18 g/ha fewer bluegill fry were produced than in control ponds, brain acetylcholinesterase (AChE) activity was not affected, and accelerated growth of both fry and adults appeared to result from heavy feeding on dead or moribund Diptera larvae that resulted from the first two applications of Abate. The routine use of Abate at the recommended rate should have little adverse effect on fishery resources.

Book Synopsis Chronic Effects of Methoxychlor on Bluegills and Aquatic Invertebrates by : Harry D. Kennedy
Download or read book Chronic Effects of Methoxychlor on Bluegills and Aquatic Invertebrates written by Harry D. Kennedy and published by . This book was released on 1970 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significantly higher numbers of aquatic insects were sampled in treated ponds than in untreated, and insect numbers at high-treatment ponds were significantly higher than at low-treatment ponds. Chironomids were dominant and significatnly increased after a certain level of treatment. Chironomids comprised 74 percent of samples from high-treatment ponds, but only 43 and 42 percent respectively fro untreated and low-treatment ponds. Methoxychlor residues were not detectable in pond-bottom mud samples.

Book excerpt: Research into ecotoxicology can be classified into three fundamental concerns: abiotic factors, which characterize the physicochemistry of environments; biotic factors, relating to biological structures and functions; and contamination factors, which define the modes of pollution of ecosystems. The most significant research methodologies currently being developed in aquatic ecotoxicology are presented, specifically experimental approaches in the laboratory

Book Synopsis Freshwater Field Tests for Hazard Assessment of Chemicals by : Ian R. Hill
Download or read book Freshwater Field Tests for Hazard Assessment of Chemicals written by Ian R. Hill and published by CRC Press. This book was released on 2018-05-04 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater field tests are an integral part of the process of hazard assessment of pesticides and other chemicals in the environment. This book brings together international experts on microcosms and mesocosms for a critical appraisal of theory and practice on the subject of freshwater field tests for hazard assessment. It is an authoritative and comprehensive summary of knowledge about freshwater field tests, with particular emphasis on their optimization for scientific and regulatory purposes. This valuable reference covers both lotic and lentic outdoor systems and addresses the choice of endpoints and test methodology. Instructive case histories show how to extrapolate test results to the real world.

Book Synopsis Proximate Composition and Caloric Content of Eight Lake Michigan Fishes by : Donald V. Rottiers
Download or read book Proximate Composition and Caloric Content of Eight Lake Michigan Fishes written by Donald V. Rottiers and published by . This book was released on 1982 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proximate composition (percentage lipid, water, fat-free dry material, ash) and caloric content of eight species of Lake Michigan fish were measured: lake trout, coho salmon, lake whitefish, bloater, alewife, rainbow smelt, deepwater sculpin, and slimy sculpin. Except for alewives, proximate composition and caloric content did not differ significantly between males and females. Although the caloric content of all species varied directly with lipid content and inversely with water content, an increase in lipid content did not always coincide with a proportional increasein caloric content when other components of fish composition were essentially unchanged. This observation suggests that the energy content of fish estimated from the proximate composition by using universal conversion factors may not necessarily be accurate.
