In an effort to revive its struggling crab farming sector, Negros Occidental is leveraging innovative all-weather technology. The new approach allows local entrepreneurs to cultivate mud crabs (*Scylla serrata*) more effectively, even amid changing climatic conditions.
Overcoming Traditional Challenges
The Ilog Entrepreneurs Association (IEA) faced significant hurdles due to the limitations of traditional farming methods. President Trinidad Diamante noted the difficulties in harvesting crabs from heavy bamboo and wood cages during adverse weather.
We had a difficult time before because we were using traditional cages... Some crabs would die.
Trinidad Diamante, Ilog Entrepreneurs Association President
- Project initiation in 2023 with a seafood drop-off initiative
- Initial grant of P315,000 from the DSWD's Sustainable Livelihood Program
The association's troubles culminated in a decline from 21 to 7 active members as extreme weather led to increased crab mortalities. To combat this, the group approached the Central Philippines State University (CPSU)-Ilog for assistance.
Innovative Crab Vertical Farming Technology
CPSU-Ilog introduced the Crab Vertical Farming Technology (CVFT), which utilizes recyclable materials for individual fattening cages. This system promotes consistent water circulation and optimal growth conditions, making it more resilient to environmental changes.
The technology is intended for transfer to the community and not for commercialization.
Dr. Paul Doronila, CPSU-Ilog Research Director
- 48 individual cages housed in a shaded structure
- Cost-effective: 40-50% cheaper than commercial systems
Since its implementation in January 2026 at a cost of P60,000, the technology has revived crab fattening efforts, prompting a resurgence in membership to 15.
Support and Future Prospects
The project received additional funding of P300,000 from the DSWD to set up another CVFT, including plans for solar power to ensure continuous operations during outages. This initiative not only boosts local production but also fosters community resilience.
Doronila also mentioned ongoing research into plant-based feed alternatives, which will reduce reliance on traditional marine feeds. As the IEA members adapt to these new methods, they are optimistic about the future of crab farming in Negros Occidental.
