Freshwater fish are species that inhabit rivers, lakes, and streams. They are a significant part of global aquaculture, providing vital food sources for human consumption and contributing to local economies. Common freshwater species include tilapia, catfish, trout, and bass, each having distinct environmental and nutritional requirements. Freshwater fish farming focuses on sustainable practices to manage water quality, reduce disease, and improve growth rates. Innovations in breeding techniques and feed formulations also support the development of healthier and more productive stocks. As demand for freshwater fish rises, aquaculture systems continue to evolve to meet market needs while minimizing environmental impact.
