Pangasius Farming in the Philippines: How to Culture Pangasius

Pangasius farming in the Philippines has emerged as a promising venture for those seeking profitable aquaculture opportunities. Delving into the world of cultivating Pangasius promises financial gains and contributes to the country’s aquatic ecosystem. This blog will explore the essential techniques and considerations to successfully culture Pangasius fish, shedding light on the pathway to sustainable and lucrative aquaculture endeavors.

What is Pangasius Farming?

Pangasius farming, also known as catfish farming, involves cultivating freshwater fish called Pangasius hypophthalmus. These fish are widely farmed due to their rapid growth and adaptability to various environments. In aquaculture, Pangasius are raised in controlled ponds or tanks. They are fed a balanced diet, typically pellets, to support their growth. Pangasius farming contributes significantly to the global seafood market, particularly in regions like the Philippines.

Pangasius Farming Techniques in the Philippines

Pangasius farming, a burgeoning practice across Asia, has found its foothold in the Philippines, albeit a novel endeavor. While Pangasius is considered a pest in Laguna Lake and Taal Lake, its potential for profitability emerges when harnessed through aquaculture, serving as valuable livestock feed due to its protein-rich composition. At its core, Pangasius farming involves cultivating this freshwater fish species.

Originating from the Mekong River in Southeast Asia, it boasts various monikers like Vietnamese River Cobbler, Swai, or Tra. Rising demand has propelled Pangasius farming’s popularity, especially given its firm, white flesh that graces dishes like fishcakes and curries. Engaging in Pangasius farming unfolds as a multi-step process. Juvenile fish are nurtured in ponds or cages and later transferred to larger tanks or ponds for substantial growth.

Their diet ranges from live foods like artemia and daphnia to specially prepared feeds. Remarkably swift growers, Pangasius can pack up to 4 kgs in 12-18 months. Successful Pangasius farming hinges on astute management. Diligent oversight of stocking densities, feeding regimens, water quality, and other variables underpins optimal yield. Vigilance against diseases is paramount, necessitating robust biosecurity measures to avert potential outbreaks.

Step-by-step Guide for Pangasius Farming in the Philippines

Site Selection: Opt for a water source without pollution, disturbances, and poachers. Ensure access to a reliable source of electricity.
Size of Culture System: The ideal size ranges from 1,600 to 2,400 sqm for ponds, with a water depth of 1.5-2 meters. Cages should be around 10×10 meters with a depth of 5 meters. Stocking density for cages ranges from 15-50/m3.
Pond Preparation: Drain and sun-dry ponds to eliminate unwanted fish species and condition the environment. Repair dikes and gates to prevent entry and escape of stocks. Remove predatory fish species to enhance yield. Lime the pond to condition the soil for pH tolerance (6.5-7.5).
Water Filling and Stocking: Fill the pond 1.5-2 meters deep to create an optimal environment. Stock Pangasius at 3-15 pcs/m2 for an 80-90% survival rate.
Pond Management: Feed Pangasius with kitchen waste, rice bran, or pellets (2.5% of ABW) for growth and quality. Monitor water parameters (pH, DO, temperature, salinity) to ensure ideal conditions. Conduct regular sampling to track growth and feeding requirements.
Harvesting: Harvest selectively or entirely after 5-6 months of culture. Achieve 1-1.5 kg weight through proper pond management.

Best Practices for Pangasius Farming in the Philippines

Site Selection: Choose a suitable location with ample water supply and proper drainage to avoid water stagnation and ensure healthy fish growth.
Water Quality Management: Regularly monitor and maintain water quality such as temperature, oxygen levels, pH, and ammonia concentration. Clean and aerate the water to support optimal fish health.
Stocking Density: Avoid overcrowding by adhering to recommended stocking densities. This prevents stress and disease outbreaks and promotes uniform growth.
Feeding Regimen: Provide balanced and nutritious diets using high-quality pellets. Adjust feeding frequency and quantity as the fish grow, ensuring efficient utilization and minimal waste.
Health Management: Implement strict biosecurity measures to prevent the spread of diseases. Quarantine fish before introducing them to the main population.
Harvesting Techniques: Employ humane and efficient harvesting methods to minimize stress and maintain fish quality. Avoid sudden changes in water conditions during harvesting.
