Download or read book Bottom Soils Sediment and Pond Aquaculture written by Claude E. Boyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture pond managers measure water-quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil-water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration. Pond fertilization may not produce phytoplankton blooms in acidic ponds. Total alkalinity is too low to provide adequate carbon dioxide for photosynthesis, and acidic soils adsorb phosphate added in fertilizer before phytoplankton can use it. Agricultural lime stone application can raise total alkalinity and neutralize soil acidity. The amount of limestone necessary to cause these changes in a pond depends on the base unsaturation and exchange acidity of the bottom soil. Two ponds with the same total alkalinity and soil pH may require vastly different quantities of limestone because they differ in exchange acidity. Aeration enhances dissolved oxygen concentrations in pond water and permits greater feed inputs to enhance fish or shrimp production. As feeding rates are raised, organic matter accumulates in pond soils. In ponds with very high feeding rates, aeration may supply enough dissolved oxygen in the water column for fish or shrimp, but it may be impossible to maintain aerobic conditions in the surface layers of pond soil. Toxic metabolites produced by microorganisms in anaerobic soils may enter the pond water and harm fish or shrimp.

Available in PDF, EPUB and Kindle. Book excerpt: This is a book about knowing God. It is for those for whom just believing (or not believing) is no longer enough. Through personal experience, anecdote and story, a priest shares an ancient, but neglected aspect of Christian prayer. Contemplation takes us into the depths of the present moment, the only reality there has ever been and so the only place where God can be found. It takes us at different times into mystical oneness with the All, into profound self-knowledge and reveals love in the midst of the world.

Book excerpt: "It's up to every single one of us to do our bit for wildlife, however small our gardens, and The Butterfly Brothers know just how that can be achieved." Alan Titchmarsh Join the rewilding movement and share your outdoor space with nature. We all have the potential to make the world a little greener. Wild Your Garden, written by Jim and Joel Ashton (aka "The Butterfly Brothers"), shows you how to create a garden that can help boost local biodiversity. Transform a paved-over yard into a lush oasis, create refuges to welcome and support native species, or turn a high-maintenance lawn into a nectar-rich mini-meadow to attract bees and butterflies. You don't need specialist knowledge or acres of land. If you have any outdoor space, you can make a difference to local wildlife, and reduce your carbon footprint, too. "Wildlife gardening is one of the most important things you can do as an individual for increasing biodiversity and mitigating the effects of climate change. From digging a pond to planting a native hedge, the Butterfly Brothers can help you every step of the way." Kate Bradbury

Download or read book A Walk around the Pond written by Gilbert Waldbauer and published by Harvard University Press. This book was released on 2008-04-15 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: A water strider darts across a pond, its feet dimpling the surface tension; a giant water bug dives below, carrying his mate’s eggs on his back; hidden among plant roots on the silty bottom, a dragonfly larva stalks unwary minnows. Barely skimming the surface, in the air above the pond, swarm mayflies with diaphanous wings. Take this walk around the pond with Gilbert Waldbauer and discover the most amazingly diverse inhabitants of the freshwater world. In his hallmark companionable style, Waldbauer introduces us to the aquatic insects that have colonized ponds, lakes, streams, and rivers, especially those in North America. Along the way we learn about the diverse forms these arthropods take, as well as their remarkable modes of life—how they have radiated into every imaginable niche in the water environment, and how they cope with the challenges such an environment poses to respiration, vision, thermoregulation, and reproduction. We encounter the caddis fly larva building its protective case and camouflaging it with stream detritus; green darner dragonflies mating midair in an acrobatic wheel formation; ants that have adapted to the tiny water environment within a pitcher plant; and insects whose adaptations to the aquatic lifestyle are furnishing biomaterials engineers with ideas for future applications in industry and consumer goods. While learning about the evolution, natural history, and ecology of these insects, readers also discover more than a little about the scientists who study them.
