What is Mudfish Farming in the Philippines

Mudfish farming in the Philippines is an emerging and potentially profitable industry, although it may not be as widely recognized as tilapia and milkfish cultivation. This aquaculture boasts several benefits, including swift high-volume harvesting, the resilience of the fish in challenging environments, and economic feasibility.

Moreover, it offers a pathway to sustainable food production, positively impacting rural communities. The guide covers crucial mudfish farming aspects, including initial setup prerequisites, effective fish nurturing practices, proficient harvest methods, and troubleshooting strategies. Furthermore, the guide delves into the rudiments of water chemistry and the identification of prevalent diseases.

Mudfish Farming Techniques in the Philippines

Mudfish farming techniques in the Philippines are being strategically developed to harness the economic potential of the Channa striata, locally known as “dalag.” Renowned for its delectable taste, rich nutrition, and medicinal value, mudfish holds promise due to its resilience against environmental challenges and adaptability to changing climates. Despite this, the country’s aquaculture landscape has yet to fully explore the potential of this species due to limited C. striata fingerling availability and a lack of comprehensive fish culture expertise.

Led by the National Fisheries Research and Development Institute (NFRDI) through the Fisheries Biotechnology Center (FBC), a two-year project commenced in October 2020. Its primary objectives encompass refining protocols, producing cost-effective hormones for induced spawning, and enhancing nursery-rearing techniques for efficient mudfish production.

The project targets an impressive output of 300,000 mudfish fingerlings distributed among local fish farmers in Central Luzon and Tanay, Rizal, facilitated by the Bureau of Fisheries and Aquatic Resources (BFAR). Another initiative spearheaded by NFRDI focuses on ensuring a consistent supply of high-quality catfish, or “hito,” fingerlings. This project aims to enhance induced spawning methods and rearing protocols.
