Across an archipelago of more than 7,600 islands, the sea has always been a lifeline. But with wild fish stocks shrinking under ecological pressure, aquaculture has stepped up as the true backbone of Philippine fisheries.

Today, fish farming does far more than just supply local markets; it secures the country’s food supply, keeps rural coastal economies afloat, and drives valuable exports. It has become an essential force in the seafood industry.

Status and contribution of Philippine aquaculture

Aquaculture consistently plays a dominant role in Philippine fisheries production. It remained the largest contributor to fisheries production in 2025. According to the Philippine Statistics Authority (PSA), aquaculture produced about 2.2 million metric tons (MMT), accounting for 55 percent of the country’s total fisheries output during the year. Production declined by almost two percent in 2024, attributed to environmental pressures, disease outbreaks, and production inefficiencies affecting major commodities.

Among the country’s 21 major fisheries commodities, production declined mainly for seaweed, tamban, skipjack tuna, and galunggong. In contrast, higher production was recorded for milkfish, tilapia, and squid.

Overall, PSA pointed out that despite remaining the country’s leading source of fisheries production, aquaculture continued to face production fluctuations, underscoring the need for innovations, stronger science-based interventions, and climate-resilient farming practices.

Role of R&D in Philippine aquaculture

Research and development (R&D) plays a crucial role in strengthening the sustainability, productivity, and resilience of the Philippine aquaculture sector. As the country’s lead institution for fisheries R&D, DA-NFRDI generates science-based technologies and management strategies that help address the industry’s evolving challenges.

At the forefront of these efforts is the DA-NFRDI’s Aquaculture Research and Development Division (ARDD), which conducts research on genetics and breeding, fish nutrition and feed development, aquatic animal health, and aquafarming systems and engineering. Through these initiatives, ARDD develops technologies that improve production efficiency, enhance product quality, and promote environmentally sustainable and climate-resilient aquaculture practices.

To respond to the needs of the aquaculture industry, ARDD undertakes research that addresses critical concerns ranging from feed and nutrition to animal health, sustainable production systems, and climate resilience.

Among its notable innovations is the development of Nano-Nutrimix®, a nanoparticle-based dietary nutrient mix for Nile tilapia produced through plant-mediated green synthesis. The technology aims to improve nutrient absorption and feed efficiency, potentially enhancing fish growth while reducing feed wastage.

Complementing this work is ARDD’s research on insect-based feeds for Nile tilapia, which explores Black Soldier Fly larvae meal as a sustainable and locally available alternative to conventional fishmeal. By reducing dependence on costly feed ingredients, the technology has the potential to lower production costs while supporting more sustainable aquaculture.

ARDD is also expanding opportunities for aquaculture diversification through research on high-value and emerging commodities. Studies on the culture of spiny lobster (Panulirus ornatus) in marine floating cages seek to identify optimal stocking densities that maximize growth and survival, while research on oyster production using bamboo raft technology offers a low-cost culture system that can improve yields and generate additional livelihood opportunities for coastal communities.

Recognizing the increasing impacts of climate change, the division is evaluating innovative production technologies such as CLSU’s Aquashading system, which aims to improve water quality, regulate pond temperature, and enhance aquaculture performance under changing environmental conditions.

ARDD is likewise advancing the application of metagenomics to better understand the microbial communities found in aquaculture environments. By providing insights into water quality, disease dynamics, and ecosystem health, this emerging technology supports more proactive and science-based aquaculture management.

Aquatic animal health also remains a major research priority. White Spot Syndrome Virus (WSSV) and Acute Hepatopancreatic Necrosis Disease (AHPND) have long been among the most devastating diseases affecting shrimp aquaculture, capable of causing massive mortalities within days and resulting in billions of pesos in economic losses worldwide. To help safeguard the industry, research on disease surveillance, early detection, diagnostics, and management strategies have been conducted to strengthen farm biosecurity and improve the country’s capacity to prevent and respond to disease outbreaks.

Through these science-based innovations, DA-NFRDI continues to equip the aquaculture sector with practical solutions that improve productivity, reduce production risks, and promote sustainable resource management. Collectively, ARDD’s research initiatives strengthen the competitiveness and resilience of Philippine aquaculture while contributing to national food security and the livelihoods of fishing and farming communities.

Ways forward

As aquaculture continues to supply more than half of the country’s fisheries production, its future will depend on the sector’s ability to adapt to emerging challenges while meeting the growing demand for safe, affordable, and sustainably produced aquatic food. The declining production recorded in recent years underscores the need for continued investments in research, innovation, and technology development.

In this regard, DA-NFRDI, through ARDD, plays a crucial role in generating the scientific knowledge and practical solutions needed to strengthen the industry’s resilience, productivity, and competitiveness. From improving feeds and animal health to developing climate-smart production systems, ARDD’s research initiatives demonstrate how science can help address real-world challenges faced by fish farmers and aquaculture stakeholders.

Moving forward, greater emphasis should be placed on scaling up and transferring proven technologies to farming communities, strengthening collaborations among research institutions, government agencies, industry partners, and local governments, and investing in emerging fields such as biotechnology, genomics, and precision aquaculture.

Continued support for sustainable feed development, disease surveillance, climate-resilient farming systems, and high-value aquaculture commodities will be essential in ensuring the long-term growth of the sector.

By bridging research, policy, and practice, the institute can further accelerate the transformation of Philippine aquaculture into a more innovative, sustainable, and inclusive industry that contributes to national food security, economic development, and the well-being of coastal and rural communities. ### (Rita dela Cruz)
