Selecting fish for aquaculture: efficiency and sustainability factors

Aquaculture is becoming a key source of seafood amid declining wild fish stocks. Tilapia is often recognized as the most sustainable and profitable option due to its rapid growth, tolerance to various conditions, and well-developed global market. However, the final choice of species depends on location, resources, market demand, environmental impact, feed efficiency, and local regulations.

Successful fish farming faces such challenges as water quality control, disease prevention, finding sustainable feed sources, regulatory compliance, and market competition. To improve environmental sustainability, recirculating aquaculture systems (RAS), integrated multi-trophic aquaculture (IMTA), and alternative protein sources, including insect meal, plant proteins, and single-cell proteins, are applied. Disease prevention includes maintaining water quality, using healthy fingerlings, biosecurity, and vaccination.

The success of the enterprise requires careful market analysis, studying consumer preferences, and working with buyers. Feed conversion ratio (FCR) remains a critical indicator, where a lower value reduces costs and environmental burden. In addition, modern farms implement automation technologies, sensors, and data analytics to monitor fish health and water parameters.
