Download or read book Abate Effects of the Organophosphate Insecticide on Bluegills and Invertebrates in Ponds written by Herman O. Sanders and published by . 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.

Download or read book Ecology of Larval Fishes in Lake Oahe South Dakota written by William Roland Nelson and published by . This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The time and location of spawning, food and larvae, and habitats used as nursery areas by young-of-the-year fishes were studied from 1972 to 1975 in South Dakota waters of Lake Oahe, a main stem Missouri River reservoir. Sampling locations were in the tributary rivres -- the Grand Moreau, and Cheyenne -- and their embayments. Year-class strength of river-spawning species was strongly correlated with river flow rates during the spawning season. Success of reservoir-spawning species was primarily dependent on above-average water levels, which inundated terrestrial vegetation to provide a substrate for egg deposition and cover for larvae. Preserving adequate streamflow and enhancing reservoir shoreline areas by managing water levels, seeding vegetation, and eliminating grazing alongshore would probably ensure adequate reproduction of most areas.

Download or read book Changes in Distribution of Trout in Great Smoky Mountains National Park 1900 1977 written by George Alan Kelly and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes have occurred in the distribution of trout in streams of Great Smoky Mountains National Park since 1900. By the mid-1970's the original range of the native brook trout had been reduced by about 70% and the species was relegated to suboptimal habitat in head water streams. Most of the stream sections lost by brook trout became the territory of the introduced rainbow trout, which in 1977 occupied about 80% of the Park waters. After 1950, brown trout introduced in State waters outside the Park established reproducing populations in some 50 miles of stream formerly occupied only by rainbow trout. If current trends continue, the recovery of brook trout in Park water may be difficult, if not impossible, and brown trout may occupy much of the territory now held by rainbow trout.

Download or read book Largemouth Bass Aquaculture written by James Tidwell and published by 5m Books Ltd. This book was released on 2019-04-30 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Largemouth bass (Micropterus salmoides) are highly prized as sports fish and increasingly as high-value food fish. The farming of largemouth bass is becoming increasingly important and international as the procedures and management for successful culture are being refined. Largemouth bass aquaculture is now widespread across the USA and increasingly in other countries worldwide: the largemouth bass aquaculture industry in China is particularly strong. Largemouth Bass Aquaculture provides comprehensive coverage of all aspects of the farming of largemouth bass, with chapters encompassing all major areas of importance, including: their history, production, environment requirements, reproduction, culture methods, diseases and major markets. Many of the world experts in the field have contributed chapters to this landmark publication and the editors are very well-known and respected worldwide. The book is fully international in scope, drawing information from all major countries where largemouth bass are farmed. Largemouth Bass Aquaculture is an important resource for those working in aquaculture, including fish farm operatives and managers, veterinarians and fish health managers, inspectors and consultants. Personnel within companies supplying the aquaculture industry with feed, technical equipment and pharmaceuticals will find a wealth of useful information within this book. Libraries in all universities and establishments teaching and researching aquaculture, fish biology, ichthyology, fisheries, aquatic sciences and veterinary studies should have copies of this comprehensive book on their shelves. 5m Books
