Fish farming is a vital agripreneurship venture in Kenya, offering significant opportunities for income generation and food security. Successful fish farming requires careful management of the aquatic environment and fish stock to optimize growth and production. This chapter addresses essential practices for conducting fish farming, focusing on species identification, water management, fish health, and marketing of hatchery products, all tailored for agripreneurs aiming to establish or improve their fish enterprises.
Identifying the appropriate fish species is fundamental to establishing a successful fish farming business. Different species have varying requirements for water quality, temperature, and diet, which influence their growth rates and market value. In Kenya, species such as Nile tilapia, African catfish, and rainbow trout are commonly farmed due to their adaptability and consumer demand. Proper species selection aligns with local environmental conditions and market preferences, enabling agripreneurs to maximize productivity and profitability.

It then discusses the critical factors involved in selecting an appropriate fish farm site, including considerations of security, the species to be reared, soil type, water availability, market access, reliable fingerling sources, and the management skills required. The construction of fish ponds is examined as a foundation for successful fish farming. Maintenance and management practices are detailed extensively, highlighting aeration, control of water flow, water quality monitoring, predator control, sludge removal, and proper cleaning techniques. The chapter also addresses the control of fish pond waste and predators to maintain a healthy environment. Causes of fish diseases are explored, categorizing them into environmental, hereditary, microbial, nutritional, and physical injury factors. Finally, the chapter concludes with the principles of fish pond stocking, emphasizing the importance of proper stocking practices for optimal fish production.
