Paperback. Etat : New. Print on Demand. This book delves into the effects of DDT, a powerful insecticide that came into widespread use in the mid-20th century, on various species of fish. The author, a prominent researcher in the field of fisheries, conducted a series of experiments in different types of ponds and aquaria to study the toxicity of DDT in relation to the size and species of fish. These experiments, conducted in the 1940s, contributed to a growing body of scientific research on the environmental impact of pesticides, which at the time was a relatively new and understudied field. The author's meticulous research highlighted the differential sensitivity of various fish species to DDT, with smaller fish and fry proving particularly vulnerable. This book provides valuable historical insights into the early scientific understanding of the ecological effects of DDT, a chemical whose use has since been largely restricted due to its harmful effects on wildlife and the environment. The book's findings remain relevant today, reminding us of the importance of understanding the complex interactions between human activities and the natural world.

Paperback. Etat : New. Print on Demand. This book provides a comprehensive guide to the practical techniques for controlling aquatic weeds in ponds and small lakes. The author, a leading expert in the field, delves into the history of weed control methods, tracing the evolution of techniques from traditional mechanical approaches to the use of chemical agents like copper sulfate and sodium arsenite. The text explores the impact of different weed species on fish populations, emphasizing the importance of maintaining a healthy balance between predator and forage fish. The book also discusses the role of fertilizers in promoting the growth of microscopic plants that outcompete larger, nuisance weeds, and the potential hazards of chemical treatments. A detailed section covers the use of new herbicides, including Diquat, Endothal, and Silvex, outlining their effectiveness and safety considerations. The authorââ â¢s detailed analysis of the various weed control methods and their environmental implications provides valuable insights into the complex relationship between aquatic ecosystems and human interventions.
