Download or read book Making Aquatic Weeds Useful written by National Research Council and published by The Minerva Group, Inc.. This book was released on 2002-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This National Academy of Sciences report describes ways to exploit aquatic weeds for grazing, and by harvesting and processing for use as compost, animal feed, pulp, paper, and fuel. The book also describes utilization for sewage and industrial wastewater.Aquatic weeds have always existed, but in recent decades their effects have been magnified by man?s more intensive use of natural water bodies - his modifying them into canals and dams, polluting them with farm and city wastewaters, and introducing aggressive plant species into new locations. These plants, among the most prolific on earth, grow luxuriantly in the tropics, weigh hundreds of tons per hectare, and can be a serious hindrance to a nation?s development efforts. Eradication of the weeds has proved impossible, and even reasonable control is difficult. Turning these weeds to productive use would be desirable, but only limited research has been carried out.This report examines methods for controlling aquatic weeds and using them to best advantage, especially those methods that show promise for less-developed countries. It emphasizes techniques for converting weeds for feed, food, fertilizer, and energy production. It examines, for example, biological control techniques in which herbivorous tropical animals (fish, waterfowl, rodents, and other mammals) convert the troublesome plants directly to meat.

Download or read book Rice Field Ecology in Northeastern Thailand written by Charles W. Heckman and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was carried out in Udorn Thani beginning in September, 1975, in order to elucidate the effects of seasonal changes on the aquatic community of a rice field. Physical and chemical changes that occur during the course of a year were recorded and related to the structure and activity of the aquatic biological com munity. A rice field was selected that is typical of the countless habitats of this kind that are found in Northeastern Thailand (Fig. 1). For a variety of reasons these habitats and their location are of special interest (Fig. 2). Figure 1. The rice field investigated, north of the province capital, Udorn Thani, Thailand. Northeastern Thailand and a small part of Laos comprise the middle Mekong Valley. Its geographic situation and climatic conditions set this area apart as a dis tinct sub-region of Southeast Asia. It is unfortunate that sufficient biological research has not yet been carried out to delimit the SUb-regions according to their fauna and flora and to fully describe the various ecosystems that occur in them. The middle Mekong Valley is one of the most neglected areas of the region, and there is no comprehensive literature on its biota. Very little ecological information is available on many of the species that abound there.
