"Biology of an Introduced Species" offers a comprehensive analysis of the biological characteristics and developmental needs of the introduced rainbow trout (Oncorhynchus mykiss) in Bolivia. The book examines the impacts of introducing this species on local ecosystems and highlights both the positive and negative consequences associated with the establishment of new species. By studying five lagoons in the Cordillera del Tunari, it provides a detailed insight into the adaptability and ecological requirements of the rainbow trout. The authors, Vivian Eliana Ocampo Bernal and Ximena Aguilera, combine scientific research with practical observations to convey a well-rounded understanding of the dynamics between introduced species and their new habitats. This specialized book is aimed at students, researchers, and professionals engaged in ecology, biology, and conservation.
