Welcome to the fascinating realm of Economic Zoology, where the intricate interplay between human civilization and animal kingdom unfolds through centuries of cultural heritage, scientific innovation, and sustainable practices. This comprehensive book explores the diverse facets of Sericulture, Apiculture, Livestock Management (including Dairy and Poultry), Aquaculture, Fish Culture, Prawn Culture, Vermiculture, and Lac Culture, offering a deep dive into their historical significance, present-day practices, and future potentials. Sericulture, the ancient art of silk production, is traced from its origins in India to its modern-day applications, highlighting the cultivation of both mulberry and non-mulberry species across Karnataka and the wider Indian landscape. The lifecycle of the Bombyx mori silkworm, mulberry cultivation techniques, and methods for reeling and processing cocoons are meticulously detailed, alongside strategies for combating silkworm diseases and pests crucial for sustaining this vital industry. Apiculture emerges as a pivotal component of agricultural ecosystems, where the lifecycle and organizational dynamics of honey bees, particularly Apis indica, play a crucial role in pollination services and the production of honey, beeswax, and other hive products. The chapter delves into indigenous beekeeping methods, advanced extraction technologies, and the challenges posed by bee diseases, viruses, and pests, underscoring the importance of holistic beekeeping practices in preserving biodiversity and ensuring food security. Livestock Management, encompassing Dairy and Poultry farming, explores the foundational principles of animal husbandry and the management practices essential for optimizing milk production, egg yields, and meat quality. From selecting suitable dairy cattle breeds to implementing innovative housing systems and feed formulations, this section equips readers with practical insights into maintaining animal welfare while enhancing farm productivity. It also addresses prevalent diseases and their control measures, critical for sustaining healthy livestock populations.
